The Complete Spitzer Survey of Stellar Structure in Galaxies (CSG)
P. M. Sánchez-Alarcón, H. Salo, J. H. Knapen +25
The Spitzer Survey of Stellar Structure in Galaxies (SG), together with its Early Type Galaxy (ETG) extension, stand as the most extensive dataset of deep, uniform mid-infrared…
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…
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…
Searching for HI around MHONGOOSE Galaxies via Spectral Stacking
S. Veronese, W. J. G. de Blok, J. Healy +19
The observed star formation rates of galaxies in the Local Universe suggests that they are replenishing their gas reservoir across cosmic time. Cosmological simulations predict tha…
Pattern speed evolution of barred galaxies in TNG50
Marcin Semczuk, Walter Dehnen, Ralph Schönrich +1
Galactic bars are found in the majority of disc galaxies. They rotate nearly rigidly with an angular frequency called pattern speed. Previous idealised simulations have shown that…
The response of the inner dark matter halo to stellar bars
Daniel A. Marostica, Rubens E. G. Machado, E. Athanassoula +1
Barred galaxies constitute about two thirds of observed disc galaxies. Bars affect not only the mass distribution of gas and stars, but also that of the dark matter. An elongation…
