The variation of the gas content of galaxy groups and pairs compared to isolated galaxies
Sambit Roychowdhury, Martin J. Meyer, Jonghwan Rhee +17
We measure how the atomic gas (HI) fraction () of groups and pairs taken as single units vary with average stellar mass ($\langle {\rm M_*} \rang…
The Atomic Hydrogen Content of Galaxies as a function of Group-Centric Radius
Wenkai Hu, Luca Cortese, Lister Staveley-Smith +5
We apply a spectral stacking technique to Westerbork Synthesis Radio Telescope observations to measure the neutral atomic hydrogen content (HI) of nearby galaxies in and around gal…
Unveiling the atomic hydrogen-halo mass relation via spectral stacking
Garima Chauhan, Claudia del P. Lagos, Adam R. H. Stevens +5
Measuring the HI-halo mass scaling relation (HIHM) is fundamental to understanding the role of HI in galaxy formation and its connection to structure formation. While direct measur…
The physical drivers of the atomic hydrogen-halo mass relation
Garima Chauhan, Claudia del P. Lagos, Adam R. H. Stevens +3
We use SHARK, a semi-analytic galaxy formation model, to investigate the physical processes involved in dictating the shape, scatter and evolution of the HI-halo mass relation at $…
HI Asymmetries in LVHIS, VIVA and HALOGAS Galaxies
T. N. Reynolds, T. Westmeier, L. Staveley-Smith +2
We present an analysis of morphological, kinematic and spectral asymmetries in observations of atomic neutral hydrogen (HI) gas from the Local Volume HI Survey (LVHIS), the VLA Ima…
The cosmic atomic hydrogen mass density as a function of mass and galaxy hierarchy from spectral stacking
Wenkai Hu, Barbara Catinella, Luca Cortese +5
We use spectral stacking to measure the contribution of galaxies of different masses and in different hierarchies to the cosmic atomic hydrogen (HI) mass density in the local Unive…
The HI Velocity Function: a test of cosmology or baryon physics?
G. Chauhan, C. D. P. Lagos, D. Obreschkow +3
Accurately predicting the shape of the HI velocity function of galaxies is regarded widely as a fundamental test of any viable dark matter model. Straightforward analyses of cosmol…
