Tracing the evolution of brightest galaxies and diffuse light in galaxy groups

B. Bilata-Woldeyes, J. D. Perea, J. M. Solanes

We present a suite of 100 cosmologically motivated, controlled N-body simulations designed to advance the understanding of the role of purely gravitational dynamics in the early fo…

The distribution of lenticular galaxies in the phase space of present-day galaxy cluster regions

M. Gort, J. L. Tous, J. M. Solanes

We investigate the environmental impact of cluster regions on the evolution of nearby S0 galaxies, focusing on their distinct quiescent and star-forming (SF) subpopulations. We sel…

MeerKAT view of Hickson Compact Groups: II. HI deficiency in the core and surrounding regions

A. Sorgho, L. Verdes-Montenegro, R. Ianjamasimanana +25

Hickson compact groups (HCGs) offer an ideal environment for investigating galaxy transformation as a result of interactions. It has been established that the evolutionary sequence…

Growth of Ex-situ Diffuse Intragroup Light in Simulated Galaxy Groups

B. Bilata-Woldeyes, J. D. Perea, J. M. Solanes

Deep surface photometry reveals a faint, diffuse baryonic component in a significant fraction of galaxy groups, permeating the intragroup space. This intragroup light (IGL) is prim…

MeerKAT view of Hickson Compact Groups:I. Data description and release

R. Ianjamasimanana, L. Verdes-Montenegro, A. Sorgho +25

Context: Hickson Compact Groups (HCGs) are dense gravitationally-bound collections of 4-10 galaxies ideal for studying gas and star formation quenching processes. Aims: We aim to u…

Growth of Diffuse Intragroup Light in Simulated Galaxy Groups

B. Bilata-Woldeyes, J. D. Perea, J. M. Solanes

The diffuse intragroup light (IGL) is a pervasive feature of galaxy groups consisting of an extended low-surface-brightness component that permeates the intergalactic medium of the…
