Title:: Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS)
Short Name:: CANDELS
Date:: 12 Feb 2020 21:03:03
Publisher:: Space Telescope Science Institute Archive
Description:: CANDELS is designed to document the first third of galactic evolution from z = 8 to 1.5 via deep imaging of more than 250,000 galaxies with WFC3/IR and ACS. It will also find the first Type Ia SNe beyond z greater than 1.5 and establish their accuracy as standard candles for cosmology. Five premier multi-wavelength sky regions are selected; each has multi-wavelength data from Spitzer and other facilities, and has extensive spectroscopy of the brighter galaxies. The use of ﬁve widely separated ﬁelds mitigates cosmic variance and yields statistically robust and complete samples of galaxies down to 109 solar masses out to z ~ 8.
