A 13CO Detection in a Brightest Cluster Galaxy [PDF]
, 2017 We present ALMA Cycle 4 observations of CO(1-0), CO(3-2), and 13CO(3-2) line emission in the brightest cluster galaxy (BCG) of RXJ0821+0752. This is one of the first detections of 13CO line emission in a galaxy cluster.

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 ...

A Radio Relic and a Search for the Central Black Hole in the Abell 2261 Brightest Cluster Galaxy [PDF]
, 2017 We present VLA images and HST/STIS spectra of sources within the center of the brightest cluster galaxy (BCG) in Abell 2261. These observations were obtained to test the hypothesis that its extremely large, flat core reflects the ejection of its ...

ON THE DETERMINATION OF GALAXY STRUCTURE ELLIPTICITY
Odessa Astronomical Publications, 2007 We discuss factors influencing the determination of the observed shape of galaxy clusters when the covariance ellipse method is involved. The analysis of 377 Abell clusters show that at greater distances from the cluster center the ellipticity is rather ...

CLASH-VLT: The Inner Slope of the MACS J1206.2-0847 Dark Matter Density Profile
The Astrophysical Journal, 2023 The inner slope ( γ _DM ) of the dark matter (DM) density profile of cosmological halos carries information about the properties of DM and/or baryonic processes affecting the halo gravitational potential.

The challenging task of determining star formation rates: the case of a massive stellar burst in the brightest cluster galaxy of Phoenix galaxy cluster [PDF]
, 2016 Star formation in galaxies at the center of cooling-flow galaxy clusters is an important phenomenon in the context of formation and evolution of massive galaxies in the Universe. Yet, star formation rates (SFRs) in such systems continue to be elusive. We
