cds-question@unistra.frultraviolet-photometrygalaxiescatalogsWe present deep UV imaging observations of the Great Observatories Origins Survey Northern (GOODS-N) field with AstroSat/UVIT (AstroSat UV Deep Field north-AUDFn), using one far-UV (FUV) (F154W, 34.0ks) and two near-UV (NUV) filters (N242W, 19.2ks; N245M, 15.5ks). The nature of the UV sky background was explored across the UVIT field, and a global mean and rms were estimated for each filter. We reach 3{sigma} detection limits of m_AB_~27.35, 27.28, and 27.02mag for a point source in the F154W, N242W, and N245M bands respectively. The 50% completeness limits of the FUV and NUV images are m_AB_=26.40 and 27.05mag respectively. We constructed point-spread functions for each band and estimated their FWHM, which were found to be almost the same: 1.18" in F154W, 1.11" in N242W, and 1.24" in N245M. We used SExtractor to separately identify sources in the FUV and NUV filters and produce the UV source catalog of the entire AUDFn field. The source count slope estimated in FUV and NUV is 0.57dex/mag (between 19 and 25mag) and 0.44dex/mag (between 18 and 25mag), respectively. The catalog contains 6839 and 16171 sources (brighter than the 50% completeness limit) in the FUV and NUV, respectively. Our FUV and NUV flux measurements of the identified sources complement existing multiband data in the GOODS-N field, and enable us to probe rest-frame FUV properties of galaxies at redshift z<1 and search for candidate Lyman continuum leakers at redshift z>0.97.2023ApJS..264...40Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/264/40CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)II/261 : GOODS initial results (Giavalisco+, 2004)J/AJ/112/1335 : Hubble Deep Field observations (Williams+ 1996)J/AJ/126/539 : The Chandra Deep Fields North and South (Alexander+, 2003)J/ApJ/592/728 : Lyman break galaxies at redshift z~3 (Steidel+, 2003)J/AJ/127/180 : The Hawaii Hubble Deep Field North (Capak+, 2004)J/ApJ/617/240 : Oxygen abundances in GOODS-North field (Kobulnicky+, 2004)J/AJ/132/1729 : Hubble Ultra Deep Field BVI-dropout sources (Beckwith+, 2006)J/ApJ/653/1004 : Galaxies at 1.4<~z<~3.0 in GOODS-North Field (Reddy+, 2006)J/ApJ/668/839 : Spectrophotometric redshifts for HUDF galaxies (Ryan+, 2007)J/ApJ/675/234 : Stellar mass functions for 0<z<4 gal.
