A Catalog of 1.4 GHz Radio Sources from the FIRST Survey

The Spitzer Extragalactic Representative Volume Survey (SERVS): Survey Definition and Goals*

“…Simpson et al (2006) have surveyed the Subaru Extragalactic Deep Survey region with the VLA to a detection limit of 100 μJy, and Bondi et al (2007) have surveyed the VVDS field in XMM-LSS at both 610 MHz with the GMRT and 1.4 GHz with the VLA to limits of ≈200 and 80 μJy, respectively. The Faint Images of the Radio Sky at Twenty cm (FIRST; White et al 1997) survey covers the Lockman and EN1 surveys and part of the XMM-LSS survey at 1.4 GHz to a sensitivity limit of ≈1 mJy at a spatial resolution of ≈5 00 .…”

THE 31 DEG2 RELEASE OF THE STRIPE 82 X-RAY SURVEY: THE POINT SOURCE CATALOG

“…Due to the relatively low space density of the radio sources detected in the FIRST (Becker et al 1995;White et al 1997) survey, we used a nearest neighbor match to find counterparts to the X-ray sources, using the same search radius of 7″ as employed in the MLE matching above. Similar to our previous Stripe 82X catalog release, we used the FIRST catalog published in 2012 which includes all sources detected between 1993 and 2011, which has a 0.75 mJy flux limit over the XMMNewton AO13 region ).…”

“…The coadded photometry reaches 1.2-2.2 magnitudes deeper than any single SDSS scan (r∼24.6 versus r∼22.2; Annis et al 2014;Jiang et al 2014), and the full field has existing optical spectroscopy from SDSS and SDSS BOSS (Data Releases 9 and 10; Ahn et al 2012Ahn et al , 2014, 2 SLAQ (Croom et al 2009), and WiggleZ (Drinkwater et al 2010), with partial coverage from DEEP2 (Newman et al 2013), PRIMUS (Coil et al 2011), 6dF (Jones et al 2004(Jones et al , 2009, the VIMOS VLT Deep Survey (VVDS Garilli et al 2008), a deep spectroscopic survey of faint quasars from Jiang et al (2006), and a pre-BOSS pilot survey using Hectospec on MMT (Ross et al 2012). Existing multi-wavelength data in Stripe 82 include near-infrared observations from UKIDSS (Hewett et al 2006;Casali et al 2007; Lawrence et al 2007) and the VISTA Hemisphere Survey (VHS; McMahon et al 2013); farinfrared coverage from Herschel over 79 deg 2 (Viero et al 2014); ultraviolet coverage with GALEX (Morrissey et al 2007); radio observations at 1.4 GHz with Faint Images of the Radio Sky at Twenty centimeters (FIRST) (Becker et al 1995;White et al 1997;Becker et al 2012;Helfand et al 2015), with deeper VLA coverage over 80 deg 2 (Hodge et al 2011); and millimeter observations with the Atacama Cosmology Telescope (ACT; Fowler et al 2007;Swetz et al 2011). Additionally, there is Spitzer coverage in the field from the Spitzer-HETDEX Exploratory Large Area survey over 28 deg 2 (SHELA; PI: C. Papovich) and the Spitzer IRAC Equatorial Survey over 110 deg 2 (SpIES; PI: G. Richards; J.…”

Weak lensing measurements in simulations of radio images

“…With the FIRST survey (Becker et al 1995;White et al 1997), Chang et al (2004) made the first detection of cosmic shear with radio data. This survey has a detection threshold of 1 mJy, with 20 resolved sources per square degree useable for weak lensing.…”
