- Description:
- Since launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has detected many hundreds of bursts from magnetar sources. While the vast majority of these bursts have been attributed to several known magnetars, there is also a small sample of magnetar-like bursts of unknown origin. Here, we present the Fermi/GBM magnetar catalog, providing the results of the temporal and spectral analyses of 440 magnetar bursts with high temporal and spectral resolution. This catalog covers the first five years of GBM magnetar observations, from 2008 July to 2013 June. We provide durations, spectral parameters for various models, fluences, and peak fluxes for all the bursts, as well as a detailed temporal analysis for SGR J1550-5418 bursts. Finally, we suggest that some of the bursts of unknown origin are associated with the newly discovered magnetar 3XMM J185246.6+0033.7.

- Description:
- Using the Florida Multi-object Imaging Near-IR Grism Observational Spectrometer (FLAMINGOS), we have conducted the FLAMINGOS Extragalactic Survey (FLAMEX), a deep imaging survey covering 7.1{deg}^2^ within the 18.6{deg}^2^ NOAO Deep Wide-Field Survey (NDWFS) regions. FLAMEX is the first deep, wide-area, nearinfrared survey to image in both the J and Ks filters, and is larger than any previous NIR survey of comparable depth. The intent of FLAMEX is to facilitate the study of galaxy and galaxy cluster evolution at 1<z<2 by providing rest-frame optical photometry for the massive galaxy population at this epoch. This effort is designed to yield a public data set that complements and augments the suite of existing surveys in the NDWFS fields. We present an overview of FLAMEX and initial results based on ~150,000 Ks-selected sources in the Bootes field. We describe the observations and reductions, quantify the data quality, and verify that the number counts are consistent with results from previous surveys. Finally, we comment on the utility of this sample for detailed study of the ERO population, and present one of the first spectroscopically confirmed z>1 galaxy clusters detected using the joint FLAMEX, NDWFS, and Spitzer IRAC Shallow Survey data sets.

- Description:
- The FLAIR Shapley-Hydra (FLASH) redshift survey catalogue consists of 4613 galaxies brighter than b_J_= 16.7 (corrected for Galactic extinction) over a 700-deg^2^ region of sky in the general direction of the Local Group motion. The survey region is a 70x10{deg} strip spanning the sky from the Shapley Supercluster to the Hydra cluster, and contains 3141 galaxies with measured redshifts. Designed to explore the effect of the galaxy concentrations in this direction (in particular the Supergalactic plane and the Shapley Supercluster) upon the Local Group motion, the 68 per cent completeness allows us to sample the large-scale structure better than similar sparsely-sampled surveys. The survey region does not overlap with the areas covered by ongoing wide-angle (Sloan or 2dF) complete redshift surveys. In this paper, the first in a series, we describe the observation and data reduction procedures, the analysis for the redshift errors and survey completeness, and present the survey data. Note that there are some minor change/improvements over the example table published in MNRAS: 1. R.A./Dec. is now J2000 rather than B1950. 2. l/b are now given to 3 decimal places rather than 1 decimal place. 3. Some additional redshifts from NED and ZCAT have been included.

- The FON Astrographic Catalogue (FONAC)
- Short Name:
- I/261
- Date:
- 21 Oct 2021
- Publisher:
- CDS
- Description:
- The FONAC is a catalogue of positions, proper motions and photometric data for 2,008,383 of Astrographic Catalogue (AC) stars covering the sky between declinations +90 and -2 degrees. The average epoch of positions is 1988.19. The catalogue is based on the measurements of more then 1700 plates which were taken with the wide-angle astrograph of the Main Astronomical Observatory (MAO) in Kiev within the FON (Photographic Survey of the Northern Sky) project. The AC data were used both as the input catalogue for measuring machine PARSEC (Programming Automatic Radial-Scanning Coordinatometer) and as the first epochs for determination of proper motions of stars. The ACT Reference Catalogue was applied for the reductions of positions and B magnitudes of stars, the GSC1.1 was used for determination of (B-V) values, and the USNO R-magnitudes were used for determination of (B-R) values. The estimated precision is 0.2 arcseconds for the positions, 3 mas/yr for the proper motions, and 0.18mag for the photometry.

- Description:
- A possible pathway for understanding the events and the mechanisms involved in galaxy formation and evolution is an in-depth comprehension of the galactic and inter-galactic fossil sub-structures with long dynamical times-scales: stars in the field and in stellar clusters. This paper continues the series of the Fornax Deep Survey (FDS). Following the previous studies dedicated to extended Fornax cluster members, in this paper we present the catalogs of compact stellar systems in the Fornax cluster as well as extended background sources and point-like sources. We derive ugri photometry of ~1.7 million sources over the ~21 square degree area of FDS centered on the bright central galaxy NGC1399. For a wider area, of ~27 square degrees extending in the direction of NGC1316, we provide gri photometry for ~3.1 million sources. To improve the morphological characterization of sources we generate multi-band image stacks by coadding the best seeing gri-band single exposures with a cut at FWHM<=0.9". We use the multi-band stacks as master detection frames, with a FWHM improved by ~15% and a FWHM variability from field to field reduced by a factor of ~2.5 compared to the pass-band with best FWHM, namely the r-band. The identification of compact sources, in particular of globular clusters (GC), is obtained from a combination of photometric (e.g. colors, magnitudes) and morphometric (e.g. concentration index, elongation, effective radius) selection criteria, by also taking as reference the properties of sources with well-defined classification from spectroscopic or high-resolution imaging data. Using the FDS catalogs, we present a preliminary analysis of globular cluster (GC) distributions in the Fornax area. The study confirms and extends further previous results which were limited to a smaller survey area. We observe the inter-galactic population of GCs, a population of mainly blue GCs centered on NGC1399, extends over ~0.9Mpc, with an ellipticity ~0.65 and a small tilt in the direction of NGC1336. Several sub-structures extend over ~0.5Mpc along various directions. Two of these structures do not cross any bright galaxy; one of them appears to be connected to NGC1404, a bright galaxy close to the cluster core and particularly poor of GCs. Using the gri catalogs we analyze the GC distribution over the extended FDS area, and do not find any obvious GC sub-structure bridging the two brightest cluster galaxies, NGC1316 and NGC1399. Although NGC1316 is more than twice brighter of NGC1399 in optical bands, using gri data, we estimate a factor of ~3-4 richer GC population around NGC1399 compared to NGC1316, out to galactocentric distances of ~40' or ~230kpc

- Description:
- We present a catalogue and atlas of low-resolution spectra of a sample of 341 objects with reliable redshifts in the FORS Deep Field (FDF). The sample contains 42 stars, 8 QSOs, and 291 galaxies up to z=5.98 objects are at z>2. For z>1 most objects were selected using photometric redshifts. The limiting I magnitude has been I=24.5 for 2<z<4. All spectra were obtained using the FORS instruments at the ESO VLT and cover the wavelength range 3300-10000{AA}. The grism 150I with a 1" slit width was used, resulting in a spectral resolution element of our spectra of 18-24{AA}, depending on the light distribution in the slit. Most objects were observed several times. Typical exposure times were about 10h for our z>2 objects. The individual spectra were S/N-optimised co-added. The final spectra were flux calibrated, smoothed to the resolution element, and corrected for atmospheric extinction. Moreover, the spectra were corrected for the atmospheric A and B bands. Redshifts and rough object types were derived by cross-correlation of the galaxy spectra with six template spectra, which had been created from high-quality FDF spectroscopic data by an iterative procedure.

- Description:
- Studies of the stellar and the HI gas kinematics in dwarf and Low Surface Brightness (LSB) galaxies are essential for deriving constraints on their dark matter distribution. Moreover, a key component to unveil in the evolution of LSBs is why some of them can be classified as superthin. We aim to investigate the nature of the proto-typical superthin galaxy Fourcade-Figueroa (FF), to understand the role played by the dark matter halo in forming its superthin shape and to investigate the mechanism that explains the observed disruption in the approaching side of the galaxy. Combining new HI 21-cm observations obtained with the Giant Metrewave Radio Telescope with archival data from the Australia Telescope Compact Array we were able to obtain sensitive HI observations of the FF galaxy. These data were modeled with a 3D tilted ring model in order to derive the rotation curve and surface brightness density of the neutral hydrogen. We subsequently used this model, combined with a stellar profile from the literature, to derive the radial distribution of the dark matter in the FF galaxy. Additionally, we used a more direct measurement of the vertical HI gas distribution as a function of the galactocentric radius to determine the flaring of the gas disk. For the FF galaxy the Navarro-Frenk-White dark matter distribution provides the best fit to the observed rotation curve. However, the differences with a pseudo-isothermal halo are small. Both models indicate that the core of the dark matter halo is compact. Even though the FF galaxy classifies as superthin, the gas thickness about the galactic centre exhibits a steep flaring of the gas which is in agreement with the edge of the stellar disk. Besides, FF is clearly disrupted towards its north-west-side, clearly observed at both, optical and HI wavelengths. As suggested previously in the literature, the compact dark matter halo might be the main responsible for the superthin structure of the stellar disk in FF. This idea is strengthened through the detection of the mentioned disruption; the fact that the galaxy is disturbed also seems to support the idea that it is not isolation that cause its superthin structure.

- The Fourth BATSE Burst Revised Catalog
- Short Name:
- IX/20A
- Date:

- Publisher:
- CDS
- Description:
- This is the fourth catalogue of the BATSE instrument on board of the Compton Gamma-ray Observatory (CGRO), launched on April 5, 1991. It contains the locations and times for 1637 triggered gamma-ray bursts (nominal energy range 50-300keV) observed from 19 April, 1991 until 29 August, 1996. This 4Br version has been revised from the version first circulated on CD-ROM in September 1997 (4B, file "4b.dat") to include improved locations for a subset of bursts that have been reprocessed using additional data. The Interplanetary Network (IPN) localization information for 147 gamma-ray bursts observed by the Burst and Transient Source Experiment between the end of the Third BATSE catalog and the end of the Fourth BATSE catalog, obtained by analyzing the arrival times of these bursts at the Ulysses and Compton Gamma-Ray Observatory (CGRO) spacecraft. are included in the table "ulysses.dat". Bursts found later (1607 triggers until 9 September 2000) are included in the file "grb.dat"; the data related to these events (those having a TrigNo>=5589) should be considered as preliminary. The Exposure table and Trigger Criteria tables are not included here; please consult the statistical results on the BATSE pages (http://gammaray.msfc.nasa.gov/batse/)

- Publisher:

- Description:
- We present the fourth in a series of catalogs of gamma-ray bursts (GRBs) observed with Fermi's Gamma-ray Burst Monitor (Fermi-GBM). It extends the six year catalog by four more years, now covering the 10yr time period from trigger enabling on 2008 July 12 to 2018 July 11. During this time period GBM triggered almost twice a day on transient events, 2356 of which we identified as cosmic GRBs. Additional trigger events were due to solar flare events, magnetar burst activities, and terrestrial gamma-ray flashes. The intention of the GBM GRB catalog series is to provide updated information to the community on the most important observables of the GBM-detected GRBs. For each GRB the location and main characteristics of the prompt emission, the duration, peak flux, and fluence are derived. The latter two quantities are calculated for the 50-300keV energy band, where the maximum energy release of GRBs in the instrument reference system is observed and also for a broader energy band from 10-1000keV, exploiting the full energy range of GBM's low-energy detectors. Furthermore, information is given on the settings of the triggering criteria and exceptional operational conditions during years 7 to 10 in the mission. This fourth catalog is an official product of the Fermi-GBM science team, and the data files containing the complete results are available from the High-Energy Astrophysics Science Archive Research Center.
