MIGHTEE-HI / LADUMA: Investigating the link between baryons and dynamics with 130 resolved HI-selected galaxies
Andreea A VÄrÄÅteanu, 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.…
Deep HI observations of cold gas inflow and outflow
W. J. G. de Blok, D. B. Fisher, K. Tachihara +8
A major question in galaxy evolution is how galaxies acquire sufficient gas to sustain their star formation rates. HI observations with high angular resolution and sensitivity to v…
HI absorption in MHONGOOSE -- Spin temperatures and cold neutral medium in nearby disk galaxies
W. J. G. de Blok, F. M. Maccagni, L. Chemin +7
Combined HI emission-absorption studies constrain the spin temperature and phase structure of the neutral atomic hydrogen interstellar medium (ISM), but have largely been limited t…
WLM: Dynamics of an isolated Dwarf Irregular Galaxy Under Ram Pressure in the Local Group
Neel Kolhe, Francois Hammer, Yanbin Yang +5
WLM is an archetypal dwarf irregular galaxy that has not experienced interactions with major Local Group galaxies within the past 8 Gyr. It has recently been shown that WLM is losi…
MUSE-ALMA Haloes XIII. Molecular gas in HI-selected galaxies
Victoria Bollo, Celine Peroux, Martin Zwaan +11
We present new results from the MUSE-ALMA Haloes survey, covering 79 galaxies associated with strong HI absorption at redshift about 0.5. Our ALMA Cycle 10 observations add 39 syst…
Investigating the HI distribution and kinematics of ESO444-G084 and [KKS2000]23: New insights from the MHONGOOSE survey
Brenda Namumba, Roger Ianjamasimanana, Bärbel Koribalski +25
We present the HI distribution, kinematics, mass modeling, and disk stability of the dwarf irregular galaxies ESO444-G084 and [KKS2000]23 using high-resolution, high-sensitivity MH…
