VizieR Online Data Catalog: HST grism obs. of CARLA galaxy cluster candidates (Noirot+, 2018)
Abstract
The Clusters Around Radio-Loud AGN (CARLA) project has used 408hr of Spitzer time to image 420 high-redshift radio-loud AGN, searching for associated galaxy clusters (Wylezalek+ 2013, J/ApJ/769/79 and 2014, J/ApJ/786/17). With IRAC exposures of ~1hr per field, CARLA reaches 10σ depths of m*+2 out to z>~2.
Our HST program consists of WFC3/F140W imaging and WFC3/G141 grism spectroscopy of the 20 densest CARLA cluster candidates, selected from 420 radio-loud AGN at z>1.3 observed in our Spitzer program (Wylezalek+ 2013, J/ApJ/769/79). A total of 10 fields are associated with high-redshift radio galaxies (HzRGs, type-2 radio-loud AGN), and the other 10 with radio-loud quasars (RLQs, type-1 RLAGN). The 20 fields were observed between 2014 October and 2016 April (Program ID: 13740). The G141 grism covers the wavelength range 1.08-1.70um with a throughput >10% at low spectral resolution, R=130.
