Resolved HI and Environmental Dynamics
M. Ramatsoku, P. Serra, N. Deg +8
Spatially resolved, deep HI observations from SKA precursors and pathfinders such as MeerKAT, FAST, and ASKAP have demonstrated their ability to reveal the complex interactions bet…
Exploring the physics of ram pressure stripping with radio continuum observations in the SKA era
Alessandro Ignesti, Ian D. Roberts, Henrik W. Edler +4
Satellite galaxies in clusters are significantly more likely to be red and passive than similar mass galaxies in the field. This fact is known as the environmental quenching of gal…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) XX. Star formation in the tidal tail of NGC 4254
A. Boselli, A. Lupi, P. Serra +26
ALMA 12CO(1-0) observations of 42 star-forming regions located outside the disc of the Virgo Cluster galaxy NGC4254 within an HI gas tail produced during the galaxy's interaction w…
The supersonic nature of jellyfish galaxies
Alessandro Ignesti, Francesca Loi, Antonino Marasco +20
All gas-rich galaxies in cluster environments are expected to experience ram-pressure stripping from the intra-cluster medium. However, only a fraction of these develop ongoing sta…
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…
The MeerKAT Fornax Survey: removal of HI gas from galaxies in the Fornax cluster
F. M. Maccagni, P. Serra
The MeerKAT Fornax Survey is conducting a thorough examinationof the nearby Fornax galaxy cluster to understand how galaxies lose their cold gas and stop forming stars in low-mass…
The MeerKAT Fornax Survey V. H i kinematics and Fornax cluster membership of the dwarf galaxy ESO 358-60
P. Kamphuis, P. Serra, D. Kleiner +2
The MeerKAT Fornax Survey (MFS) is a large survey project mapping the HI in the Fornax cluster. Most of the cluster members detected in HI show significant signs of interaction wit…
MeerKAT HI imaging of the jellyfish galaxy ESO 137-001
M. Ramatsoku, P. Serra, M. Sun +2
We present MeerKAT HI observations of ESO 137-001, a quintessential jellyfish galaxy with long multi-phase tails formed due to the interaction with the intra-cluster medium of its…
The MeerKAT Fornax Survey. III. Ram-pressure stripping of the tidally interacting galaxy NGC 1427A in the Fornax cluster
P. Serra, T. A. Oosterloo, P. Kamphuis +16
We present MeerKAT Fornax Survey HI observations of NGC 1427A, a blue irregular galaxy with a stellar mass of 2e+9 Msun located near the centre of the Fornax galaxy cluster. Thanks…
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…
WALLABY Pre-Pilot Survey: The effects of tidal interaction on radial distribution of color in galaxies of the Eridanus supergroup
Shun Wang, Jing Wang, Bi-Qing For +21
We study the tidal interaction of galaxies in the Eridanus supergroup, using HI data from the pre-pilot survey of WALLABY (Widefield ASKAP L-band Legacy All-sky Blind surveY). We o…
The detection of a massive chain of dark HI clouds in the GAMA G23 Field
Gyula I. G. Jozsa, T. H. Jarrett, Michelle Cluver +18
We report on the detection of a large, extended HI cloud complex in the GAMA G23 field, located at a redshift of , observed as part of the MeerHOGS campaign (a pilot…
MeerKAT HI commissioning observations of MHONGOOSE galaxy ESO 302-G014
W. J. G. de Blok, E. Athanassoula, A. Bosma +43
We present the results of three commissioning HI observations obtained with the MeerKAT radio telescope. These observations make up part of the preparation for the forthcoming MHON…
Spectro-polarimetric observations of the CIZA J2242.8+5301 northern radio relic: no evidence of high-frequency steepening
Francesca Loi, Matteo Murgia, Valentina Vacca +16
Observations of radio relics at very high frequency (>10 GHz) can help to understand how particles age and are (re-)accelerated in galaxy cluster outskirts and how magnetic fields…
The recurrent nuclear activity of Fornax A and its interaction with the cold gas
F. M. Maccagni, P. Serra, M. Murgia +3
Sensitive (noise \Jyb), high-resolution () MeerKAT observations of Fornax A show that its giant lobes have a double-shell morphology, where dense filaments a…
The flickering nuclear activity of Fornax A
F. M. Maccagni, M. Murgia, P. Serra +13
We present new observations of Fornax A taken at 1 GHz with the MeerKAT telescope and at 6 GHz with the Sardinia Radio Telescope (SRT). The sensitive (noise ~16 micro-Jy beam$^{-1}…
HALOGAS observations of NGC 5023 and UGC 2082: Modeling of non-cylindrically symmetric gas distributions in edge-on galaxies
P. Kamphuis, R. J. Rand, G. I. G. Józsa +7
In recent years it has become clear that the vertical structure of disk galaxies is a key ingredient for understanding galaxy evolution. In particular, the presence and structure o…
