The MeerKAT Fornax Survey VI. The collapse of the galaxy HI Mass Function in Fornax

D. Kleiner, P. Serra, A. Loni +6

We present the deepest HI mass Function (HIMF) ever measured, outside the Local Group. The observations are part of the MeerKAT Fornax Survey and cover a 4 x 4 deg^2 field, corresp…

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)…

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…

A depolarizing HI tidal tail in the western lobe of Fornax A

Francesca Loi, Paolo Serra, Matteo Murgia +8

Recent MeerKAT neutral hydrogen (HI) observations of Fornax A reveal tidal material intersecting in projection the western lobe of this radio galaxy. We found a spatial coincidence…

Apertif, Phased Array Feeds for the Westerbork Synthesis Radio Telescope

W. A. van Cappellen, T. A. Oosterloo, M. A. W. Verheijen +87

We describe the APERture Tile In Focus (Apertif) system, a phased array feed (PAF) upgrade of the Westerbork Synthesis Radio Telescope which has transformed this telescope into a h…

The best of both worlds: Combining LOFAR and Apertif to derive resolved radio spectral index images

R. Morganti, T. A. Oosterloo, M. Brienza +36

Supermassive black holes at the centres of galaxies can cycle through periods of activity and quiescence. Characterising the duty cycle of active galactic nuclei is crucial for und…
