MIGHTEE-HI: Environmental effects of cosmic filaments on extragalactic HI detections in the COSMOS and XMM-LSS fields
Seoyoung Lyla Jung, Madalina N. Tudorache, Matt J. Jarvis +8
Cosmic filaments have been recognised as influencing galaxy evolution, but their connection to galactic cold gas reservoirs is elusive, particularly at low redshifts. We investigat…
pop-cosmos: Disentangling galaxy properties from observables using data-driven approaches
Benedict Van den Bussche, Sinan Deger, Hiranya V. Peiris +6
The physical processes that shape a galaxy's spectrum are strongly degenerate in observations, obscuring which processes act independently. Leveraging the pop-cosmos generative gal…
pop-cosmos: Galaxy size evolution across structural and star-formation classifications in COSMOS-Web
Madalina N. Tudorache, Hiranya V. Peiris, Stephen Thorp +7
Galaxy sizes are correlated with stellar mass and redshift, as characterised by size scaling relations. The inferred forms of these scaling relations are sensitive to how galaxies…
Studying HI and the Cosmic Web in the Era of SKA
Hengxing Pan, Martin Meyer, Madalina N. Tudorache +5
Neutral atomic hydrogen plays a central role in the evolution of galaxies. Yet our understanding of how gas is accreted onto galactic disks, and the way this is governed by the cas…
pop-cosmos: Redshifts and physical properties of KiDS-1000 galaxies
Anik Halder, Hiranya V. Peiris, Stephen Thorp +8
Principled Bayesian inference of galaxy properties has not previously been performed for wide-area weak lensing surveys with millions of sources. We address this gap by applying th…
A 15 Mpc rotating galaxy filament at redshift z = 0.032
Madalina N. Tudorache, S. L. Jung, M. J. Jarvis +6
Understanding the cold atomic hydrogen gas (HI) within cosmic filaments has the potential to pin down the relationship between the low density gas in the cosmic web and how the gal…
MIGHTEE-HI: The direct detection of neutral hydrogen in galaxies at
Matt J. Jarvis, Madalina N. Tudorache, I. Heywood +18
Atomic hydrogen constitutes the gas reservoir from which molecular gas and star formation in galaxies emerges. However, the weakness of the line means it has been difficult to dire…
MIGHTEE-HI: The star-forming properties of HI selected galaxies
Madalina N. Tudorache, M. J. Jarvis, A. A. Ponomareva +9
The interplay between atomic gas, the star-formation history of a galaxy and its environment are intrinsically linked, and we need to decouple these dependencies to understand thei…
Probing magnetic fields in the circumgalactic medium using polarization data from MIGHTEE
K. Böckmann, M. Brüggen, V. Heesen +10
The detection and study of magnetic fields surrounding galaxies is important to understand galaxy evolution since magnetic fields are tracers for dynamical processes in the circumg…
MIGHTEE-HI: The first MeerKAT HI mass function from an untargeted interferometric survey
Anastasia A. Ponomareva, Matt J. Jarvis, Hengxing Pan +17
We present the first measurement of the HI mass function (HIMF) using data from MeerKAT, based on 276 direct detections from the MIGHTEE Survey Early Science data covering a period…
MIGHTEE-HI: The relation between the HI gas in galaxies and the cosmic web
Madalina N. Tudorache, M. J. Jarvis, I. Heywood +11
We study the 3D axis of rotation (3D spin) of 77 HI galaxies from the MIGHTEE-HI Early Science observations, and its relation to the filaments of the cosmic web. For this HI-select…
MIGHTEE-HI: Discovery of an HI-rich galaxy group at z = 0.044 with MeerKAT
Shilpa Ranchod, Roger P. Deane, Anastasia A. Ponomareva +13
We present the serendipitous discovery of a galaxy group in the XMM-LSS field with MIGHTEE Early Science observations. Twenty galaxies are detected in HI in this group…
