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…
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…
Fully comprehensive diagnostic of galaxy activity using principal components of visible spectra: implementation on nearby S0s
J. L. Tous, J. M. Solanes, J. D. Perea
We introduce a novel galaxy classification methodology based on the visible spectra of a sample of over 68,000 nearby () Sloan Digital Sky Survey lenticular (S0) galaxie…
