Atomic hydrogen reservoirs in quiescent galaxies at z = 0.4

A. Bianchetti, G. Rodighiero, D. Donevski +11

Context. Based on Local Universe observations, quiescent galaxies (QGs) host lower to no HI compared to star-forming galaxies (SFGs), but no constraints have been derived so far at…

Investigating the H i mass-size relation using the Simba cosmological simulations

Omphile Rabyang, Ed Elson

Observational studies have established a remarkably tight power-law relationship between the H I masses and sizes of late-type galaxies, known as the H I mass-size relation. This r…

Semi-empirical constraints on the HI mass function of star-forming galaxies and at from interferometric surveys

Francesco Sinigaglia, Alessandro Bianchetti, Giulia Rodighiero +5

The HI mass function is a crucial tool to understand the evolution of the HI content in galaxies over cosmic times. We aim to derive semi-empirical constraints at by c…

MeerKAT-derived HI kinematics and the Baryonic Tully-Fisher Relation in the X-ray luminous cluster Abell 3408

Xola Ndaliso, Tariq Blecher, Roger Deane +1

Significant advances in observational capabilities are continuously transforming our understanding of the dense environment of galaxy clusters and its impact on individual galaxies…

New constraints on the evolution of the MHI-M* scaling relation combining CHILES and MIGHTEE-HI data

Alessandro Bianchetti, Francesco Sinigaglia, Giulia Rodighiero +23

The improved sensitivity of interferometric facilities to the 21-cm line of atomic hydrogen (HI) enables studies of its properties in galaxies beyond the local Universe. In this wo…

Looking At the Distant Universe with the MeerKAT Array: the HI Mass Function in the Local Universe

Amir Kazemi-Moridani, Andrew J. Baker, Marc Verheijen +24

We present measurements of the neutral atomic hydrogen (HI) mass function (HIMF) and cosmic HI density () at from the Looking at the Distant Univ…
