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…
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…
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…
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…
Measures of luminous and dark matter in galaxies across time
Jonathan Freundlich, Gauri Sharma, Sabine Thater +14
Dark matter is one of the pillars of the current standard model of structure formation: it is assumed to constitute most of the matter in the Universe. However, it can so far only…
Disk galaxies are self-similar: the universality of the HI-to-Halo mass ratio for isolated disks
Marie Korsaga, Benoit Famaey, Jonathan Freundlich +7
Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter.…
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…
LADUMA: Discovery of a luminous OH megamaser at
Marcin Glowacki, Jordan D. Collier, Amir Kazemi-Moridani +65
In the local Universe, OH megamasers (OHMs) are detected almost exclusively in infrared-luminous galaxies, with a prevalence that increases with IR luminosity, suggesting that they…
The phantom dark matter halos of the Local Volume in the context of modified Newtonian dynamics
P. -A. Oria, B. Famaey, G. F. Thomas +8
We explore the predictions of Milgromian gravity (MOND) in the Local Universe by considering the distribution of the `phantom' dark matter (PDM) that would source the MOND gravitat…
GHASP: an H kinematical survey of spiral galaxies -- XIII. Distribution of luminous and dark matter in spiral and irregular nearby galaxies using H and HI rotation curves and WISE photometry
M. Korsaga, B. Epinat, P. Amram +3
We present the mass models of 31 spiral and irregular nearby galaxies obtained using hybrid rotation curves (RCs) combining high resolution GHASP Fabry-Perot H RCs and extended…
Early Observations of the MHONGOOSE Galaxies: Getting Ready for MeerKAT
A. Sorgho, C. Carignan, D. J. Pisano +9
We present early observations of 20 galaxies in the MHONGOOSE survey galaxies using KAT-7, the GBT, and MeerKAT. We present the best calibrators for five of the MHONGOOSE galaxies…
GHASP: an H kinematics survey of spiral galaxies - XII. Distribution of luminous and dark matter in spiral and irregular nearby galaxies using R-band photometry
Marie Korsaga, Philippe Amram, Claude Carignan +1
Mass models of 100 nearby spiral and irregular galaxies, covering morphological types from Sa to Irr, are computed using H rotation curves and R-band surface brightness prof…
GHASP: an H kinematical survey of spiral galaxies - XI. Distribution of luminous and dark matter in spiral and irregular nearby galaxies using WISE photometry
Marie Korsaga, Claude Carignan, Philippe Amram +2
We present the mass distribution of a sample of 121 nearby galaxies with high quality optical velocity fields and available infra-red 3.4 m data. Contrary to previou…
