MIGHTEE-HI / LADUMA: Investigating the link between baryons and dynamics with 130 resolved HI-selected galaxies

Andreea A Vărăşteanu, Andreea A Vărăşteanu, Matt J. Jarvis +16

The baryonic Tully-Fisher relation (bTFR) and the radial acceleration relation (RAR) link the observed dynamics in galaxies to that expected from their baryonic mass distributions.…

MIGHTEE-HI: HI catalogue of 293 sources for the COSMOS field and comparative study of 3-dimensional source finding methods

Michalina Maksymowicz-Maciata, Natasha Maddox, Catherine Hale +12

We present a catalogue of HI sources extracted from the MIGHTEE survey data cubes covering the COSMOS field. The catalogue contains 293 sources in the redshift range of 0.004 < z <…

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: 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…

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 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…
