Abstract:
Using a sample of 98 galaxy clusters recently imaged in the
near-infrared with the European Southern Observatory (ESO) New
Technology Telescope, WIYN telescope and William Herschel Telescope,
supplemented with 33 clusters from the ESO archive, we measure how the
stellar mass of the most massive galaxies in the universe, namely
brightest cluster galaxies (BCGs), increases with time. Most of the
BCGs in this new sample lie in the redshift range 0.2<z<0.6, which
has been noted in recent works to mark an epoch over which the growth
in the stellar mass of BCGs stalls. From this sample of 132 clusters,
we create a subsample of 102 systems that includes only those clusters
that have estimates of the cluster mass. We combine the BCGs in this
subsample with BCGs from the literature, and find that the growth in
stellar mass of BCGs from 10 billion years ago to the present epoch is
broadly consistent with recent semi-analytic and semi-empirical
models. As in other recent studies, tentative evidence indicates that
the stellar mass growth rate of BCGs may be slowing in the past 3.5
billion years. Further work in collecting larger samples, and in
better comparing observations with theory using mock images, is
required if a more detailed comparison between the models and the data
is to be made.
Description:
We utilize a sample of 98 newly imaged galaxy clusters from the
RELICS (REd Lens Infrared Cluster Survey) survey within this study.
The data were collected during six observing runs on three instruments
over a period spanning from 2013 October to 2015 March. The
instruments utilized were the SofI2 camera on the New Technology
Telescope at the European Southern Observatory (ESO) La Silla
Observatory in Chile, WHIRC3 on the WIYN telescope at the Kitt Peak
National Observatory and LIRIS4 on the William Herschel Telescope
(WHT) in La Palma, Spain.
