Abstract The UltraViolet Imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) survey is a Hubble Space Telescope (HST) Cycle-26 Treasury Program, allocated in total 164 orbits primary Wide-Field Camera 3 Ultraviolet and VISible light F275W imaging with coordinated parallel Advanced for Surveys F435W imaging, on four five premier extragalactic fields: GOODS-N, GOODS-S, EGS, COSMOS. We introduce this by presenting comprehensive analysis absolute...
Abstract UVCANDELS is a Hubble Space Telescope Cycle-26 Treasury Program awarded 164 orbits of primary ultraviolet (UV) F275W imaging and coordinated parallel optical F435W in four CANDELS fields—GOODS-N, GOODS-S, EGS, COSMOS—covering total area ∼426 arcmin 2 . This ∼2.7 times larger than the covered by previous deep-field space UV data combined, reaching depth about 27 28 ABmag (5 σ 0.”2 apertures) for F435W, respectively. Along with new photometric catalogs, we present an analysis...
Abstract The UltraViolet Imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) survey provided ultraviolet F275W imaging with coordinated parallel optical F435W in four five CANDELS fields: GOODS-N, GOODS-S, EGS, and COSMOS, covering a total area ∼426 arcmin 2 . UVCANDELS takes primary WFC3/UVIS exposures at uniform 3-orbit depth ACS (in parallel) slightly varying due to roll angle constraints overlap from increased field view camera, reaching...
Abstract The UltraViolet imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) program provides deep Hubble Space Telescope (HST) F275W and F435W over four CANDELS fields (GOODS-N, GOODS-S, COSMOS, Extended Groth Strip). We combine this newly acquired UV with existing HST from as well ancillary data to obtain robust photometric redshifts reliable estimates for galaxy physical properties 150,000 galaxies in ∼430 arcmin 2 UVCANDELS area. Here, we...
UVCANDELS is a HST Cycle-26 Treasury Program awarded 164 orbits of primary ultraviolet (UV) F275W imaging and coordinated parallel optical F435W in four CANDELS fields: GOODS-N, GOODS-S, EGS, COSMOS, covering total area $\sim426$ arcmin$^2$. This $\sim2.7$ times larger than the covered by previous deep-field space UV data combined, reaching depth about 27 28 ABmag ($5\sigma$ $0.2"$ apertures) for F435W, respectively. Along with new photometric catalogs, we present an analysis rest-frame...
