- Description:
- As part of our programme to map the large-scale distribution of galaxies behind the southern Milky Way, we observed 314 optically-selected, partially-obscured galaxies in the Zone of Avoidance (ZOA) in the Crux and Great Attractor (GA) regions. An additional 29 galaxies were observed in the Vela ZOA survey region (because of the small numbers they are not discussed any further). The observations were conducted with the Parkes 64m (210 ft) radio telescope, in a single-pixel pointed mode, reaching an rms noise level of typically 2-6mJy over the velocity search range of 400<v<10500km/s. A total of 162 galaxies were detected (plus 14 galaxies in the Vela region). The detection rate is slightly higher than for the Hydra/Antlia region (52% versus 45%) observed in the same way.

- Description:
- The 2MFGC catalog we have used contains 18020 galaxies selected from among the extended objects in the 2MASS infrared sky survey as having apparent ratios of the axes b/a<0.3. Most of them are spiral galaxies of later morphological types whose disks are seen almost edge-on. The individual distances to the 2724 2MFGC galaxies with known rotation velocities and radial velocities are determined using a multiparameter infrared Tully-Fisher relation. A list of the distances and peculiar velocities of these galaxies is presented. The collective motion of the 2MFGC galaxies relative to the cosmic microwave background is characterized by a velocity V=199+/-37km/s in the direction l=304+/-11, b=-8+/-8 . Our list is currently the most representative and uniform sample for analyzing non-Hubble motions of galaxies on a scale of ~100Mpc.

- Description:
- The Photoelectric Astrolabe Mark I (PHA I) has been revised with a new combined prism which could work as an almucantar with zenith distance of 45 degree, to measure continuous declinations at the latitude of Irkutsk, Russia ({phi}=52 degree). The PHA I has been working at the astronomical base of VS NIIFTRI in Irkutsk since Nov. 1995, based on an international cooperation agreement of near 4 years for star catalogue and EOP measurements. The first observing program was ended in June 1997, giving corrections in both right ascension and declination to 200 stars with no blind zone in declination determination, which most astrolabe catalogues in the world usually would have.

- Phoenix Deep Survey: optical and NIR catalogs
- Short Name:

- Date:

- Publisher:
- CDS
- Description:
- The Phoenix Deep Survey is a multiwavelength galaxy survey based on deep 1.4GHz radio imaging. The primary goal of this survey is to investigate the properties of star formation in galaxies and to trace the evolution in those properties to a redshift z=1, covering a significant fraction of the age of the universe. By compiling a sample of star-forming galaxies based on selection at radio wavelengths we eliminate possible biases due to dust obscuration, a significant issue when selecting objects at optical and ultraviolet wavelengths. In this paper, we present the catalogs and results of deep optical (UBVRI) and near-infrared (Ks) imaging of the deepest region of the existing decimetric radio imaging. The observations and data processing are summarized and the construction of the optical source catalogs described, together with the details of the identification of candidate optical counterparts to the radio catalogs. Based on our UBVRIKs imaging, photometric redshift estimates for the optical counterparts to the radio detections are explored.

- Photometric Catalog of Northern Bright Galaxies
- Short Name:

- CDS
- Description:
- Galaxies are the most massive, luminous astronomical objects bound by self gravity and comprise the major fraction of luminous mass in the universe. Recent investigations of galaxies often require statistical analysis of a large body of observational data. High degree of homogeneity of the data is the key point to the success of such investigations. This catalog presents homogeneous photometric parameters of 791 northern bright galaxies on the basis of modern photographic surface photometry. Sample galaxies are taken from the Revised Shapley-Ames Catalog of Bright Galaxies (Sandage and Tammann 1981) and most of them are members of the Local Super-cluster. Observations were made with the 105cm Schmidt telescope at the Kiso Observatory, Institute of Astronomy, University of Tokyo, in the photographic V band (Kodak IIa-D emulsion combined with a Schott GG 495 filter) mostly during 1984-1988. Sample galaxies photographed on a total of 280 Schmidt plates were scanned with the PDS 2020 GMS microdensitometer at the Kiso Observatory during April-August 1988. Data reduction for standard surface photometry was carried out using a software library SPIRAL (Ichikawa et al. 1987; Okamura 1988) during July-September 1988. The intensive plate measurement and data reduction secure high homogeneity of the present data. This catalog is the first machine-readable version (Ver.1) of Part II (The Catalog) of the 'Photometric Atlas of Northern Bright Galaxies' (Kodaira et al. 1990), which also includes in Part III illustrative information such as images, isophotal maps, luminosity profiles, and ellipses fitted to the isophotes. Image data of sample galaxies can be obtained in FITS format magnetic tapes upon request, and it is planned to distribute them on CD-ROMs. We request that those errors in this catalog that are found by the user be transmitted to S. Ichikawa, National Astronomical Observatory, Mitaka, Tokyo 181 Japan (e-mail : richika@c1.mtk.nao.ac.jp) so that they can be corrected in future versions.

- Description:
- We present a deep photometric (B- and R-band) catalog and an associated spectroscopic redshift survey conducted in the vicinity of the Hubble Deep Field-South. The spectroscopy yields 53 extragalactic redshifts in the range 0<z<1.4, substantially increasing the body of spectroscopic work in this field to over 200 objects. The targets are selected from deep Anglo-Australian Telescope prime-focus images complete to R<24, and the spectroscopy is 50% complete at R=23.

- Photometry catalogs for the Lockman Hole
- Short Name:

- Publisher:
- CDS
- Description:
- We present broadband photometry and photometric redshifts for 187611 sources located in ~0.5deg^2^ in the Lockman Hole area. The catalog includes 388 X-ray-detected sources identified with the very deep XMM-Newton observations available for an area of 0.2deg^2^. The source detection was performed on the Rc-, z'-, and B-band images and the available photometry is spanning from the far-ultraviolet to the mid-infrared, reaching in the best-case scenario 21 bands. Astrometry corrections and photometric cross-calibrations over the entire data set allowed the computation of accurate photometric redshifts. Special treatment is undertaken for the X-ray sources, the majority of which are active galactic nuclei (AGNs). For normal galaxies, comparing the photometric redshifts to the 253 available spectroscopic redshifts, we achieve an accuracy of {sigma}_{Delta}z/(1+z)_=0.036, with 12.6% outliers. For the X-ray-detected sources, compared to 115 spectroscopic redshifts, the accuracy is {sigma}_{Delta}z/(1+z)_=0.069, with 18.3% outliers, where the outliers are defined as sources with |z_phot_-z_spec_|>0.15x(1+z_spec_).

- Description:
- We present the results of Thuan & Gunn r CCD imaging observations of the Universidad Complutense de Madrid (UCM) sample of emission-line galaxies (ELGs), selected by the presence of H{alpha} emission in low-resolution objective prism spectra. In this work we characterize photometrically and morphologically a total of 212 objects from the UCM survey. This Paper presents the observations and basic reductions, and lists a set of photometric parameters calculated for each UCM object. In addition, for the first time in a ELGs sample, we have determined the morphological classification of the objects using simultaneously five different criteria.
