THE LUMINOSITY PROFILES OF BRIGHTEST CLUSTER GALAXIES [PDF]
The Astrophysical Journal Supplement Series, 2011 (Abridged) We have derived detailed R band luminosity profiles and structural parameters for a total of 430 brightest cluster galaxies (BCGs), down to a limiting surface brightness of 24.5 mag/arcsec^2. Light profiles were initially fitted with a Sersic's R^(1/n) model, but we found that 205 (~48) BCGs require a double component model to accurately ...

Ionized nebulae surrounding brightest cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 We present IFU observations of six emission-line nebulae that surround the central galaxy of cool core clusters. Qualitatively similar nebulae are observed in cool core clusters even when the dynamics and possibly formation and excitation source are different.

BRIGHTEST CLUSTER GALAXIES AT THE PRESENT EPOCH [PDF]
The Astrophysical Journal, 2014 We have obtained photometry and spectroscopy of 433 z ⩽ 0.08 brightest cluster galaxies (BCGs) in a full-sky survey of Abell clusters to construct a BCG sample suitable for probing deviations from the local Hubble flow. The BCG Hubble diagram over 0 < z <

A multiwavelength photometric census of AGN and star formation activity in the brightest cluster galaxies of X-ray selected clusters [PDF]
, 2016 Despite their reputation as being 'red and dead', the unique environment inhabited by brightest cluster galaxies (BCGs) can often lead to a self-regulated feedback cycle between radiatively cooling intracluster gas and star formation and active galactic ...

Diversity in the stellar velocity dispersion profiles of a large sample of brightest cluster galaxies z ≤ 0.3 [PDF]
, 2018 We analyse spatially-resolved deep optical spectroscopy of Brightest Cluster Galaxies (BCGs) located in 32 massive clusters with redshifts of 0.05 $\leq z \leq$ 0.30, to investigate their velocity dispersion profiles.

GLOBULAR CLUSTER SYSTEMS IN BRIGHTEST CLUSTER GALAXIES. II. NGC 6166 [PDF]
The Astrophysical Journal, 2015 We present new deep photometry of the globular cluster system (GCS) around NGC 6166, the central supergiant galaxy in Abell 2199. Hubble Space Telescope data from the Advanced Camera for Surveys and WFC3 cameras in F475W and F814W are used to determine ...

AGN in Brightest Cluster Galaxies
, 2018 We present a systematic investigation of the nuclear activity in Brighest Cluster Galaxies through cosmic epochs. By combining X-ray, Radio, optical and IR data, we constrain the origin of the feeding gas and the accretion regime, as well as the feedback processes affecting the surrounding Intra Cluster Medium and star formation events in the BCGs ...
