Deep Galex Uv Survey of the Kepler Field. I. Point Source Catalog
We report observations of a deep near-ultraviolet (NUV) survey of the Kepler field made in 2012 with the Galaxy Evolution Explorer (GALEX) Complete All-Sky UV Survey Extension (CAUSE). The GALEX-CAUSE Kepler survey (GCK) covers 104 square degrees of the Kepler field and reaches limiting magnitude NUV ≃ 22.6 at 3σ. Analysis of the GCK survey has yielded a catalog of 669,928 NUV sources, of which...
متن کاملThe Galex Uv Luminosity Function of the Cluster of Galaxies
We present the GALEX NUV (2310Å) and FUV (1530Å) galaxy luminosity functions of the nearby cluster of galaxies A1367 in the magnitude range−20.3 ≤ MAB ≤ −13.3. The luminosity functions are consistent with previous (∼ 2 mag shallower) estimates based on the FOCA and FAUST experiments, but display a steeper faint-end slope than the GALEX luminosity function for local field galaxies. Using spectro...
متن کاملPhotometric Catalogue of Quasars and Other Point Sources in the Sloan Digital Sky Survey
We present a catalogue of about 6 million unresolved photometric detections in the Sloan Digital Sky Survey Seventh Data Release classifying them into stars, galaxies and quasars. We use a machine learning classifier trained on a subset of spectroscopically confirmed objects from 14th to 22nd magnitude in the SDSS i-band. Our catalogue consists of 2,430,625 quasars, 3,544,036 stars and 63,586 u...
متن کاملStatistical properties of extragalactic sources in the New Extragalactic WMAP Point Source (NEWPS) catalogue
We present results on spectral index distributions, number counts, redshift distribution and other general statistical properties of extragalactic point sources in the NEWPS5σ sample (López-Caniego et al. 2007). The flux calibrations at all the WMAP channels have been reassessed both by comparison with ground based observations and through estimates of the effective beam areas. The two methods ...
متن کاملPhotometric Selection of QSO Candidates From GALEX Sources
We present a catalog of 36 120 QSO candidates from the GALaxy Evolution EXplorer (GALEX) GALEX Release Two (GR2) UV catalog and the USNO-A2.0 optical catalog. The selection criteria are established using known quasars from the Sloan Digital Sky Survey (SDSS). The SDSS sample is then used to assign individual probabilities to our GALEX-USNO candidates. The mean probability is ∼ 50%, and would ri...
