Abstract:
Large surveys of galaxy clusters with the Hubble Space Telescope (HST)
and Spitzer, including the Cluster Lensing And Supernova survey with
Hubble and the Frontier Fields, have demonstrated the power of strong
gravitational lensing to efficiently deliver large samples of
high-redshift galaxies. We extend this strategy through a wider,
shallower survey named RELICS, the Reionization Lensing Cluster
Survey, described here. Our 188-orbit Hubble Treasury Program observed
41 clusters at 0.182≤z≤0.972 with Advanced Camera for Surveys (ACS)
and WFC3/IR imaging spanning 0.4-1.7µm. We selected 21 of the most
massive clusters known based on Planck PSZ2 estimates and
20 additional clusters based on observed or inferred lensing strength.
RELICS observed 46 WFC3/IR pointings (∼200arcmin2) each with two
orbits divided among four filters (F105W, F125W, F140W, and F160W) and
ACS imaging as needed to achieve single-orbit depth in each of three
filters (F435W, F606W, and F814W). As previously reported by
Salmon+ (2020ApJ...889..189S 2020ApJ...889..189S), we discovered over 300 z∼6-10
candidates, including the brightest z∼6 candidates known, and the most
distant spatially resolved lensed arc known at z∼10. Spitzer IRAC
imaging (945hr awarded, plus 100 archival, spanning 3.0-5.0µm) has
crucially enabled us to distinguish z∼10 candidates from z∼2
interlopers. For each cluster, two HST observing epochs were staggered
by about a month, enabling us to discover 11 supernovae, including
3 lensed supernovae, which we followed up with 20 orbits from our
program.
Description:
Of the 41 Reionization Lensing Cluster Survey (RELICS) clusters,
28 had been observed previously by HST with ACS and/or WFC3/UVIS. Our
188-orbit HST Treasury Program (Cycle 23; GO 14096; PI Coe;
Deputy PI Bradley) obtained additional observations with ACS and
WFC3/IR. For each field, we observed two orbits of WFC3/IR split among
four filters: F105W, F125W, F140W, and F160W. And for each cluster, we
observed three orbits of ACS split among F435W, F606W, and F814W,
minus any archival imaging. See Section 4.

Note (1): Magnitudes have been corrected for galactic extinction: E(B-V)=0.01260
based on Schlafly & Finkbeiner 2011ApJ...737..103S 2011ApJ...737..103S
Note (2): Vulnerable to cosmic rays
Note (3): Isophotal fluxes multiplied by correction factors (given in Table 2)
for extinction.
Note (4): Bayesian Photometric Redshifts are derived using BPZ
(Benitez+ 2000ApJ...536..571B 2000ApJ...536..571B and Coe+ 2006AJ....132..926C 2006AJ....132..926C). These
results are intended for galaxies only. Stars may be pruned as having
higher values of SExtractor stellarity. For each object, the most
likely redshift and template are given by zb and tb, and the 95%
confidence range. See Section 5.3.
Note (5): The templates used here are 5 ellipticals (1-5), 2 spirals (6-7), and
4 starburst galaxies (8-11); see Figure 5. Higher values of tb generally
correspond to bluer templates.
Note (6): Objects with Chi2<1 generally have photometry well fit by the
model SEDs.
Note (7): Limit flag as follows:
> = 1-sigma limit: non-detection
u = unobserved (outside FOV, in chip gap, etc.)

Global notes:
Note (G1): Cluster portion (e.g., NE) if observed by RELICS with two
WFC3/IR pointings.
