The galactic HI-to-halo mass relation from isolated galaxies to cosmological hydrodynamic simulations
Marie Korsaga, Jonathan Freundlich, Benoit Famaey +15
The relation between HI and dark matter (DM) halo masses provides key insights into gas accretion and the regulation of galaxy formation. In a previous study based on SPARC and LIT…
The molecular gas of four ram pressure stripped galaxies in the core of the Hydra I cluster
Clara C. de la Casa, Kelley M. Hess, Nikki Zabel +15
We present new CO(1-0) measurements from ALMA and new HI measurements from MeerKAT in four ram pressure stripped (RPS) galaxies in the core of the Hydra I cluster: NGC 3312, NGC 33…
Angular momentum in isolated disc galaxies: Insights from TNG100
A. Sorgho, L. Verdes-Montenegro, M. Baes +5
Angular momentum is a fundamental property that shapes the evolution of disc galaxies, strongly influencing the internal mechanisms that regulate star formation. Its content within…
The size of the HI disk across different environments: isolated, compact groups, clusters, and pairs
R. Ianjamasimanana, L. Verdes-Montenegro, K. M. Hess +8
The 21 cm line of atomic hydrogen (HI) is a sensitive tracer of the outer disk of galaxies, where environmental signatures are most apparent. The relative extent of HI disks compar…
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…
Ram-pressure signatures in the dwarf irregular galaxy SextansB revealed by deep MeerKAT HI observations
Brenda Namumba, Neel Kolhe, Francois Hammer +12
The impact of extremely low-density environments such as the diffuse intergalactic medium (IGM) on the neutral gas distribution of dwarf galaxies remains poorly explored observatio…
WLM: Dynamics of an isolated Dwarf Irregular Galaxy Under Ram Pressure in the Local Group
Neel Kolhe, Francois Hammer, Yanbin Yang +5
WLM is an archetypal dwarf irregular galaxy that has not experienced interactions with major Local Group galaxies within the past 8 Gyr. It has recently been shown that WLM is losi…
MeerKAT view of Hickson Compact Groups: II. HI deficiency in the core and surrounding regions
A. Sorgho, L. Verdes-Montenegro, R. Ianjamasimanana +25
Hickson compact groups (HCGs) offer an ideal environment for investigating galaxy transformation as a result of interactions. It has been established that the evolutionary sequence…
MeerKAT view of Hickson Compact Groups:I. Data description and release
R. Ianjamasimanana, L. Verdes-Montenegro, A. Sorgho +25
Context: Hickson Compact Groups (HCGs) are dense gravitationally-bound collections of 4-10 galaxies ideal for studying gas and star formation quenching processes. Aims: We aim to u…
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…
MIGHTEE-\HI: Possible interactions with the galaxy NGC~895
Brenda Namumba, Javier Román, Jesus Falcon Barroso +29
The transformation and evolution of a galaxy is strongly influenced by interactions with its environment. Neutral hydrogen (\HI) is an excellent way to trace these interactions. He…
Evidence of ram pressure stripping of WLM, a dwarf galaxy far away from any large host galaxy
Yanbin Yang, Roger Ianjamasimanana, Francois Hammer +5
Dwarf galaxies are affected by all the evolutionary processes normally at work in galaxies of any mass. As fainter and less massive galaxies, however, dwarf galaxies are particular…
The extended HI halo of NGC 4945 as seen by MeerKAT
Roger Ianjamasimanana, B. S. Koribalski, Gyula I. G. Józsa +20
Observations of the neutral atomic hydrogen (HI) in the nuclear starburst galaxy NGC 4945 with MeerKAT are presented. We find a large amount of halo gas, previously missed by HI ob…
The MeerKAT Galaxy Cluster Legacy Survey I. Survey Overview and Highlights
K. Knowles, W. D. Cotton, L. Rudnick +148
MeerKAT's large number of antennas, spanning 8 km with a densely packed 1 km core, create a powerful instrument for wide-area surveys, with high sensitivity over a wide range of an…
MeerKAT-64 discovers wide-spread tidal debris in the nearby NGC 7232 galaxy group
Brenda Namumba, Baerbel Silvia Koribalski, Gyula I. G. Józsa +24
We report the discovery of large amounts of previously undetected cold neutral atomic hydrogen (\HI) around the core triplet galaxies in the nearby NGC~7232 galaxy group with MeerK…
