COSMOS Brightest Group Galaxies -- III: Evolution of stellar ages

G. Gozaliasl, A. Finoguenov, A. Babul +15

The unique characteristics of the brightest group galaxies (BGGs) link the evolutionary continuum between galaxies like the Milky Way and more massive BCGs in dense clusters. This…

A hot core in the group-dominant elliptical galaxy NGC 777

Ewan O'Sullivan, Kamlesh Rajpurohit, Gerrit Schellenberger +8

NGC 777 provides an example of a phenomenon observed in some group-central ellipticals, in which the temperature profile shows a central peak, despite the short central cooling tim…

SIMBA-C: An updated chemical enrichment model for galactic chemical evolution in the SIMBA simulation

Renier T. Hough, Douglas Rennehan, Chiaki Kobayashi +4

We introduce a new chemical enrichment and stellar feedback model into GIZMO, using the SIMBA sub-grid models as a base. Based on the state-of-the-art chemical evolution model of K…

Cool and gusty, with a chance of rain: Dynamics of multiphase CGM around massive galaxies in the Romulus simulations

Vida Saeedzadeh, S. Lyla Jung, Douglas Rennehan +8

Using high-resolution {\sc Romulus} simulations, we explore the origin and evolution of the circumgalactic medium (CGM) in the region 0.1 $\leq \mathrm{R}/\mathrm{R}_\mathrm{500} \…

Brightest Cluster Galaxy Formation in the z=4.3 Protocluster SPT2349-56: Discovery of a Radio-Loud AGN

Scott C. Chapman, Ryley Hill, Manuel Aravena +29

We have observed the z=4.3 protocluster SPT2349-56 with ATCA with the aim of detecting radio-loud active galactic nuclei (AGN) amongst the ~30 submillimeter galaxies identified in…

Spatially-resolved properties of early-type group-dominant galaxies with MUSE: gas content, ionisation mechanisms and metallicity gradients

P. Lagos, S. I. Loubser, T. C. Scott +6

With the goal of a thorough investigation of the ionised gas and its origin in early-type group-dominant galaxies, we present archival MUSE data for 18 galaxies from the Complete L…
