2. Catalog of stars in Sgr dwarf galaxy

Title:
Catalog of stars in Sgr dwarf galaxy
Short Name:
J/AJ/145/163
Date:
21 Oct 2021
Publisher:
CDS
Description:
We measure the spatial density of F turnoff stars in the Sagittarius dwarf tidal stream, from Sloan Digital Sky Survey data, using statistical photometric parallax. We find a set of continuous, consistent parameters that describe the leading Sgr stream's position, direction, and width for 15 stripes in the north Galactic cap, and three stripes in the south Galactic cap. We produce a catalog of stars that has the density characteristics of the dominant leading Sgr tidal stream that can be compared with simulations. We find that the width of the leading (north) tidal tail is consistent with recent triaxial and axisymmetric halo model simulations. The density along the stream is roughly consistent with common disruption models in the north, but possibly not in the south. We explore the possibility that one or more of the dominant Sgr streams has been misidentified, and that one or more of the "bifurcated" pieces is the real Sgr tidal tail, but we do not reach definite conclusions. If two dwarf progenitors are assumed, fits to the planes of the dominant and "bifurcated" tidal tails favor an association of the Sgr dwarf spheroidal galaxy with the dominant southern stream and the "bifurcated" stream in the north. In the north Galactic cap, the best fit Hernquist density profile for the smooth component of the stellar halo is oblate, with a flattening parameter q=0.53, and a scale length of r_0_=6.73. The southern data for both the tidal debris and the smooth component of the stellar halo do not match the model fits to the north, although the stellar halo is still overwhelmingly oblate. Finally, we verify that we can reproduce the parameter fits on the asynchronous MilkyWay@home volunteer computing platform.

Publisher:
CDS
Description:
This catalog contains the fourteenth, fifteenth, and sixteenth sections of the 5C Cambridge survey of radio sources. This catalog reports further 408 and 1407 MHz observations of the 5C12 area (Benn et al. 1982), which were carried out with the One-Mile Telescope at Cambridge to provide more accurate positions for the 5C12 sources and to extend the 5C12 catalog. Positions and flux densities were measured for 691 sources in a 5 degree x 5 degree area near the north galactic pole. The catalog data include the serial (source) number, right ascension (B1950.0) and declination (B1950.0), rms uncertainty in 408 MHz position, peak 408 MHz flux density and rms uncertainty, effective envelope attenuation (P_eff) at 408 MHz, difference between the 408 MHz and 1407 MHz positions, rms uncertainty in 1407 MHz position, peak 1407 MHz flux density and uncertainty, envelope attenuation P at 1407 MHz and radio spectral index between 408 MHz and 1407 MHz.

6. 2dFGRS Wiener reconstruction of cosmic web
ID:
ivo://CDS.VizieR/J/MNRAS/352/939
Title:
2dFGRS Wiener reconstruction of cosmic web
Short Name:
J/MNRAS/352/939
Date:
21 Oct 2021
Publisher:
CDS
Description:
We reconstruct the underlying density field of the Two-degree Field Galaxy Redshift Survey (2dFGRS, <VII/226>) for the redshift range 0.035<z<0.200 using the Wiener filtering method. The Wiener filter suppresses shot noise and accounts for selection and incompleteness effects. The method relies on prior knowledge of the 2dF power spectrum of fluctuations and the combination of matter density and bias parameters, however the results are only slightly affected by changes to these parameters. We present maps of the density field. We use a variable smoothing technique with two different effective resolutions: 5 and 10h^-1^Mpc at the median redshift of the survey. We identify all major superclusters and voids in the survey. In particular, we find two large superclusters and two large local voids. The full set of colour maps can be viewed on the World Wide Web at http://www.ast.cam.ac.uk/~pirin .

Title:
Faint Galaxies at the North Galactic Pole
Short Name:
VII/208
Date:
21 Oct 2021
Publisher:
CDS
Description:
The North Galactic Pole Canada-France-Hawaii Telescope Catalogue of faint galaxies is made available. We provide positions, photometric and structural parameters for more than 50000 galaxies. The J and F magnitudes were obtained from IIIaJ and IIIaF CFHT prime focus plates respectively. This catalogue have been used in many studies of faint galaxy properties. Galaxy counts, colour distributions and clustering properties of faint galaxies have been obtained with these data. Statistical properties of stars have been studied as well. For details refer to Infante and Pritchet (1992ApJS...83..237I), Pritchet and Infante (1992ApJ...399L..35P), Infante (1994A&A...282..353), Infante (1994A&AS..107..413I) and Infante and Pritchet (1995ApJ...439..565I). The magnitude errors range from: +/-0.3mag at J=24 to less than +/-0.1 at J=20 +/-0.3mag at F=23 to less than +/-0.1 at F=19 The rms uncertainty in the zero points is 0.022 (J) and 0.038 (F)
8. F2-G5 Stars in a North Galactic Pole Region
ID:
ivo://CDS.VizieR/III/9A
Title:
F2-G5 Stars in a North Galactic Pole Region
Short Name:
III/9A
Date:
21 Oct 2021
Publisher:
CDS
Description:
The catalog is an objective-prism survey for stars of spectral classes F2 to G5 in a region of high galactic latitude. The catalog contains 1127 stars and is complete to a limiting photographic magnitude of 12.5. The photographic plates used permit a separation of the stars into narrow and well-defined spectral classes. The spectral classification of the stars in the catalog is based on the Yerkes MK system. The catalog is subdivided into one-degree declination zones as are the DM catalogs. The degree zones are based on 1855 coordinates. The catalog includes sequence numbers of the stars, BD and HD numbers, positions (B1950), B magnitudes, spectral types, and remarks.
9. G5 and later stars in a North Galactic Pole region
ID:
ivo://CDS.VizieR/III/10B
Title:
G5 and later stars in a North Galactic Pole region
Short Name:
III/10B
Date:
21 Oct 2021
Publisher:
CDS
Description:
The catalog is an objective-prism survey of late-type stars in a region of 396 square degrees surrounding the north galactic pole. The objective-prism spectra employed have a dispersion of 58 nm/mm at H-{gamma} and extend into the ultraviolet region. The catalog contains the magnitudes and spectral classes of 4027 stars of class G5 and later, complete to a limiting photographic magnitude of 13.0. The spectral classification of the stars is based on the Yerkes system. The catalog includes the serial numbers of the stars corresponding to the numbers on the identification charts in Upgren (1984), BD and HD numbers, B magnitudes, spectral classes, and letters designating the subregion and identification chart on which each star is located. This survey was undertaken to determine the space densities at varying distances from the galactic plane. Accurate separation of the surveyed stars of G5 and later into giants and dwarfs was achieved through the use of the UV region as well as conventional methods of classification. The resulting catalog of 4027 stars is probably complete over the region to a limiting photographic magnitude of 13.0. The region covered by the survey is the same as that discussed by Slettebak and Stock (1959) and is in the approximate range RA 11:30 to 13:00, Declination +25 to +50 (B1950.0). The catalog includes all M and Carbon stars previously published by Upgren (1960). For a discussion of the classification criteria, the combining of multiple classifications (each spectral image was classified twice), the determination of magnitudes, and additional details about the catalog, the source reference should be consulted. Corrections, accurate positions, more identifications, and remarks have been added in Nov. 2015 by B. Skiff in the file "positions.dat"; see the "History" section below for details.
10. Interstellar polarization. VI.
ID:
ivo://CDS.VizieR/J/A+A/384/1050
Title:
Interstellar polarization. VI.
Short Name:
J/A+A/384/1050
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present new interstellar polarization measurements for 116 stars at high galactic latitudes. Our data show that Markkanen's cloud - the main polarization structure seen in the North Galactic Pole area (b>75{deg}) extends further towards lower latitudes. Especially, we have found a new dust formation in the area 35{deg}<l<45{deg}, 57{deg}<b<63{deg}. Interstellar polarization in this part of the sky peaks at 0.7%, which gives a lower limit to the extinction A_V_>0.23mag. Polarization vectors in this cloud are very well aligned along the direction of l=50{deg}. On the IRAS 100 micron map this dust structure shows up as a bright emission area. We discuss the new polarization map extending from circumpolar to lower latitudes and point out features which suggest that Markkanen's cloud may be a part of the dust lane in the inner edge of the local spiral or spur.
