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…
MIGHTEE-HI: Mass Models and Dark Matter properties
Anastasia A. Ponomareva, P. E. Mancera Piña, A. A. Vărăşteanu +17
Measuring galaxy rotation curves is critical for inferring the properties of dark-matter haloes in the Lambda Cold Dark Matter (CDM) paradigm. We present HI rotation curves and…
MIGHTEE HI observations of low surface brightness and ultra-diffuse galaxies in the XMM-LSS field
Elizabeth A. K. Adams, Barbara Šiljeg, Anastasia Ponomareva +8
Untargeted neutral hydrogen (HI) surveys are well suited to identifying low surface brightness galaxies (LSBGs) that are gas rich, and they offer a complementary view to optically…
MIGHTEE-HI: The HI mass-stellar mass relation of massive galaxies and the HI mass function at 0.25<z<0.5
Hengxing Pan, Matt J. Jarvis, Ian Heywood +6
The relationship between the already formed stellar mass in a galaxy and the gas reservoir of neutral atomic hydrogen, is a key element in our understanding of how gas is turned in…
Uncovering Extraplanar Gas in UGCA 250 with the Ultra-deep MHONGOOSE Survey
Sushma Kurapati, D. J. Pisano, W. J. G. de Blok +28

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…
Revealing hidden structures in the Zone of Avoidance -- a blind MeerKAT HI Survey of the Vela Supercluster
Sambatriniaina H. A. Rajohnson, Renée C. Kraan-Korteweg, Bradley S. Frank +7
We conducted the MeerKAT Vela Supercluster survey, named VelaHI, to bridge the gap between the Vela SARAO MeerKAT Galactic Plane Survey (VelaSMGPS, $-2^{\circ} \leq b \leq 1^…
MIGHTEE-HI: deep spectral line observations of the COSMOS field
I. Heywood, A. A. Ponomareva, N. Maddox +16
The MIGHTEE survey utilises the South African MeerKAT radio telescope to observe four extragalactic deep fields, with the aim of advancing our understanding of the formation and ev…
WALLABY Pilot Survey: the Tully-Fisher relation in the NGC 4808, Vela and NGC 5044 fields
Jeremy Mould, T. H. Jarrett, Hélène Courtois +18
The Tully-Fisher Relation (TFR) is a well-known empirical relationship between the luminosity of a spiral galaxy and its circular velocity, allowing us to estimate redshift indepen…
HI Galaxy Signatures in the SARAO MeerKAT Galactic Plane Survey -- III. Unveiling the obscured part of the Vela Supercluster
Sambatriniaina H. A. Rajohnson, Renée C. Kraan-Korteweg, Hao Chen +8
We conducted a search for HI emission of the gas-rich galaxies in the Vela region () to explore the Vela S…
MIGHTEE-HI: HI galaxy properties in the large scale structure environment at z~0.37 from a stacking experiment
Francesco Sinigaglia, Giulia Rodighiero, Ed Elson +20
We present the first measurement of HI mass of star-forming galaxies in different large scale structure environments from a blind survey at . In particular, we carry ou…
HI Galaxy Signatures in the SARAO MeerKAT Galactic Plane Survey -- II. The Local Void and its substructure
Sushma Kurapati, Renée C. Kraan-Korteweg, D. J. Pisano +7
The Local Void is one of the nearest large voids, located at a distance of 23 Mpc. It lies largely behind the Galactic Bulge and is therefore extremely difficult to observe. We use…
