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…
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…
Searching for HI around MHONGOOSE Galaxies via Spectral Stacking
S. Veronese, W. J. G. de Blok, J. Healy +19
The observed star formation rates of galaxies in the Local Universe suggests that they are replenishing their gas reservoir across cosmic time. Cosmological simulations predict tha…
MHONGOOSE discovery of a gas-rich low-surface brightness galaxy in the Dorado Group
F. M. Maccagni, W. J. G. de Blok, P. E. Mancera Piña +28
We present the discovery of a low-mass gas-rich low-surface brightness galaxy in the Dorado Group, at a distance of 17.7 Mpc. Combining deep MeerKAT 21-cm observations from the Mee…
MHONGOOSE -- A MeerKAT Nearby Galaxy HI Survey
W. J. G. de Blok, J. Healy, F. M. Maccagni +57
The MHONGOOSE (MeerKAT HI Observations of Nearby Galactic Objects: Observing Southern Emitters) survey maps the distribution and kinematics of the neutral atomic hydrogen (HI) gas…
Possible origins of anomalous HI gas around MHONGOOSE galaxy, NGC 5068
J. Healy, W. J. G. de Blok, F. M. Maccagni +17
The existing reservoirs of neutral atomic hydrogen gas (HI) in galaxies are insufficient to have maintained the observed levels of star formation without some kind of replenish…
Extended neutral hydrogen filamentary network in NGC 2403
S. Veronese, W. J. G. de Blok, F. Walter
We present new neutral hydrogen (HI) observations of the nearby galaxy NGC 2403 to determine the nature of a low-column density cloud that was detected earlier by the Green Bank Te…
