RELICS science topics include:
• high-redshift galaxies
• cluster mass scaling relations
• supernovae to empirically test lensing models
• dark matter particle constraints
RELICS is obtaining the first HST infrared imaging of some of the most massive clusters according to Planck. Our less massive clusters are generally known to be exceptional lenses with existing ACS imaging.

We obtained 188 HST orbits (PI Coe) and 946 Spitzer hours (PI Bradač) to observe 46 fields strongly lensed by 41 massive galaxy clusters plus 19 blank fields in parallel (6' away).
