A search for HI absorption in distant star-forming galaxies with ASKAP-FLASH - II. Direct observations and stacking of 21 cm line

Sophie L. Eden, Elaine M. Sadler, Kevin A. Pimbblet +5

We present results of a search for associated and intervening HI 21 cm absorption in star-forming galaxies and a control sample of radio galaxies at 0.4 < < 1.0, using ASKAP's…

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…

Tracing neutral hydrogen in UGCA 320: A MHONGOOSE perspective on an edge-on dwarf galaxy in a group environment

Nikki Zabel, D. J. Pisano, Sushma Kurapati +8

We present a detailed analysis of the neutral atomic gas (HI) in the dwarf galaxy UGCA 320, observed with the MeerKAT telescope as part of the MHONGOOSE (MeerKAT HI Observations of…

LeMMINGs VII: 5 GHz, 50 mas e-MERLIN observations of a statistically complete sample of nearby AGN

D. R. A. Williams-Baldwin, R. D. Baldi, R. J. Beswick +36

We present 5 GHz e-MERLIN radio images at 50 mas resolution of the nuclear regions of the Legacy e-MERLIN Multi-band Imaging of Nearby Galaxies survey (LeMMINGs), the deepest stati…

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…

Pavo: Stellar feedback in action in a low-mass dwarf galaxy

Michael G. Jones, Martin P. Rey, David J. Sand +13

MeerKAT observations of the recently discovered, extremely low mass galaxy, Pavo, have revealed a neutral gas (HI) reservoir that was undetected in archival HI single dish data. We…

MeerKAT Discovery of an Infalling Cold Gas Tail onto the Nearby Barred Spiral Galaxy, NGC 5643

K. C. Santana, F. M. Maccagni, R. Deane +1

The detailed study of gas flows in local Active Galactic Nuclei (AGN) is essential for understanding the regulation of star formation and black hole growth, which are fundamental t…

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…

PHANGS-MeerKAT and MHONGOOSE HI observations of nearby spiral galaxies: physical drivers of the molecular gas fraction,

Cosima Eibensteiner, Jiayi Sun, Frank Bigiel +36

The molecular-to-atomic gas ratio is crucial to the evolution of the interstellar medium in galaxies. We investigate the balance between the atomic () and molecular gas…

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…
