The ultra-deep HI radial profiles of late-type galaxies from MHONGOOSE
S. Veronese, W. J. G. de Blok, E. Brinks +4
Galaxy discs have a finite extent, yet how and where their neutral atomic hydrogen (HI) components end is not fully understood. The existence of a break in the HI disc at column de…
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…
The inside-out quenching of the MHONGOOSE galaxy NGC 1371
S. Veronese, W. J. G. de Blok, F. Fraternali +5
We present the deepest 21-cm spectral line and 1.4 GHz broad-band continuum observations of nearby early-type spiral galaxy NGC 1371 as part of the MeerKAT HI Observations of Nearb…
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…
HI within and around observed and simulated galaxy discs -- Comparing MeerKAT observations with mock data from TNG50 and FIRE-2
A. Marasco, W. J. G. de Blok, F. M. Maccagni +12
Atomic hydrogen (HI) is an ideal tracer of gas flows in and around galaxies, and it is uniquely observable in the nearby Universe. Here we make use of wide-field (~1 square degree)…
Uncovering Extraplanar Gas in UGCA 250 with the Ultra-deep MHONGOOSE Survey
Sushma Kurapati, D. J. Pisano, W. J. G. de Blok +28
We use the neutral atomic hydrogen (HI) observations of the edge-on galaxy UGCA 250, taken as part of the MeerKAT HI Observations of Nearby Galactic Objects - Observing Southern Em…
