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…
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…
The multi-wavelength Tully-Fisher relation in the TNG50 cosmological simulation
Maarten Baes, Andrea Gebek, Sabelo Kunene +8
The Tully-Fisher relation (TFR) is one of the most important and widely used empirical correlations in extragalactic astronomy. Apart from its importance as a secondary distance in…
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…
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 -- 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…
The AMIGA sample of isolated galaxies -- Effects of Environment on Angular momentum
A. Sorgho, L. Verdes-Montenegro, K. M. Hess +4
We investigate the relationship between the baryonic angular momentum and mass for a sample of 36 isolated disc galaxies with resolved HI kinematics and infrared WISE photometry dr…
SKA Science Data Challenge 2: analysis and results
P. Hartley, A. Bonaldi, R. Braun +105
The Square Kilometre Array Observatory (SKAO) will explore the radio sky to new depths in order to conduct transformational science. SKAO data products made available to astronomer…
A Census of the Extended Neutral Hydrogen Around 18 MHONGOOSE Galaxies
Amy Sardone, D. J. Pisano, N. M. Pingel +3
We present the analysis of the diffuse, low column density HI environment of 18 MHONGOOSE galaxies. We obtained deep observations with the Robert C. Byrd Green Bank Telescope, and…
