Southern Cosmology Survey Iii: Qso’s from Combined Galex and Optical Photometry
We present catalogs of QSO candidates selected using photometry from GALEX combined with SDSS in the Stripe 82 region and Blanco Cosmology Survey (BCS) near declination −55 degrees. The SDSS region contains ≃ 700 objects with magnitude i < 20 and ≃ 3600 objects with i < 21.5 in a ≃ 60 square degree sky region, while the BCS region contains ≃ 280 objects with magnitude i < 20 and ∼ 2000 objects ...
متن کاملCosmology with Gtc . a Combined Mm - Optical Galaxy Cluster Survey
The CMB Planck satellite (ESA) will provide a catalogue of ≈ 30000 galaxy clusters (Sunyaev-Zel'dovich effect) between redshift 0 and ≈ 2-3 (depending on the cosmological model). This hughe catalogue of clusters will allow detailed studies of the evolution of the cluster population with redshift which will constrain the cosmological model. The identification of the high redshift clusters should...
متن کاملA survey for post common-envelope binary stars using GALEX and SDSS photometry
We report the first results of our programme to obtain multi-epoch radial velocity measurements of stars with a strong far-UV excess to identify post common-envelope binaries (PCEBs). The targets have been identified using optical photometry from SDSS DR4, ultraviolet photometry from GALEX GR2 and proper motion information from SDSS DR5. We have obtained spectra at two or more epochs for 36 tar...
متن کاملThe Hamburg/ESO survey for bright QSOs III. A large flux-limited sample of QSOs
We present a new sample of 415 bright QSOs and Seyfert 1 nuclei drawn from the Hamburg/ESO survey (HES). The sample is spectroscopically 99% complete and well-defined in terms of flux and redshift limits. Optical magnitudes are in the interval 13 <∼ BJ <∼ 17.5, redshifts range within 0 < z < 3.2. More than 50% of the objects in the sample are new discoveries. We describe the selection technique...
متن کاملSouthern Cosmology Survey I: Optical Cluster Detections and Predictions for the Southern Common-area Millimeter-wave Experiments
We present first results from the Southern Cosmology Survey, a new multiwavelength survey of the southern sky coordinated with the Atacama Cosmology Telescope (ACT), a recently commissioned ground-based mm-band Cosmic Microwave Background experiment. This article presents a full analysis of archival optical multi-band imaging data covering an 8 square degree region near right ascension 23 hours...
