MIGHTEE-HI: Mass Models and Dark Matter properties

Anastasia A. Ponomareva, P. E. Mancera Piña, A. A. Vărăşteanu +17

Measuring galaxy rotation curves is critical for inferring the properties of dark-matter haloes in the Lambda Cold Dark Matter (CDM) paradigm. We present HI rotation curves and…

MIGHTEE-HI: The HI mass-stellar mass relation of massive galaxies and the HI mass function at 0.25<z<0.5

Hengxing Pan, Matt J. Jarvis, Ian Heywood +6

The relationship between the already formed stellar mass in a galaxy and the gas reservoir of neutral atomic hydrogen, is a key element in our understanding of how gas is turned in…

A 15 Mpc rotating galaxy filament at redshift z = 0.032

Madalina N. Tudorache, S. L. Jung, M. J. Jarvis +6

Understanding the cold atomic hydrogen gas (HI) within cosmic filaments has the potential to pin down the relationship between the low density gas in the cosmic web and how the gal…

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…

MIGHTEE-HI: The direct detection of neutral hydrogen in galaxies at

Matt J. Jarvis, Madalina N. Tudorache, I. Heywood +18

Atomic hydrogen constitutes the gas reservoir from which molecular gas and star formation in galaxies emerges. However, the weakness of the line means it has been difficult to dire…

MIGHTEE-HI: The radial acceleration relation with resolved stellar mass measurements

Andreea A. Vărăşteanu, Matt J. Jarvis, Anastasia A. Ponomareva +8

The radial acceleration relation (RAR) is a fundamental relation linking baryonic and dark matter in galaxies by relating the observed acceleration derived from dynamics to the one…
