The connection between massive galaxies and their dark matter haloes from to from the combined COSMOS, XMM-LSS and ECDF-S fields
Natalia Stylianou, Matt J. Jarvis, Rohan G. Varadaraj +4
Understanding how galaxies populate and grow within dark matter haloes is essential for linking the observed evolution of galaxies to the hierarchical growth of structure. We prese…
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…
MIGHTEE-HI / LADUMA: Investigating the link between baryons and dynamics with 130 resolved HI-selected galaxies
Andreea A Vărăşteanu, Matt J. Jarvis, Harry Desmond +15
The baryonic Tully-Fisher relation (bTFR) and the radial acceleration relation (RAR) link the observed dynamics in galaxies to that expected from their baryonic mass distributions.…
Forward-modelling the Tolman and distance-duality tests with IllustrisTNG
Harry Desmond, Tariq Yasin, Richard Stiskalek +1
The Tolman surface-brightness test and the angular-size distance-duality test are two complementary probes of the same underlying relation between luminosity and angular-diameter d…
The Pulsar Radial Acceleration Relation
Tariq Yasin, Harry Desmond
The radial acceleration relation (RAR) links observed and baryonic accelerations, and is best established in rotation curves of late-type galaxies. Pulsar timing, which measures li…
Testing cosmic anisotropy with cluster scaling relations
Tariq Yasin, Richard Stiskalek, Harry Desmond +2
We test claims of large-scale anisotropy in the local expansion rate using cluster scaling relations as distance indicators. Using a Bayesian forward model, we jointly fit the X-ra…
Testing subhalo abundance matching with galaxy kinematics
Fedir Boreiko, Tariq Yasin, Harry Desmond +2
The rotation velocities of disc galaxies trace dark matter halo structure, providing direct constraints on the galaxy--halo connection. We construct a Bayesian forward model to con…
Symbolically regressing dark matter halo profiles using weak lensing
Alicia Martín, Tariq Yasin, Deaglan J. Bartlett +2
The structure of dark matter haloes is often described by radial density profiles motivated by cosmological simulations. These are typically assumed to have a fixed functional form…
The Cosmological Dipole in Tilted Anisotropic Universes
Alicia Martín, Constantinos Skordis, Deaglan J. Bartlett +3
There is tentative evidence for a mismatch between the rest frames of matter and the cosmic microwave background, the "quasar dipole anomaly". We consider such a dipole in tilted a…
Constraining dark matter halo profiles with symbolic regression
Alicia Martín, Tariq Yasin, Deaglan J. Bartlett +2
Dark matter haloes are typically characterised by radial density profiles with fixed forms motivated by simulations (e.g. NFW). However, simulation predictions depend on uncertain…
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…
Renzo's rule revisited: A statistical study of galaxies' baryon - dark matter coupling
Enoch Ko, Tariq Yasin, Harry Desmond +2
We present a systematic statistical analysis of an informal astrophysical phenomenon known as Renzo's rule (or Sancisi's law), which states that "for any feature in a galaxy's lumi…
MIGHTEE-HI: The radial acceleration relation with resolved stellar mass measurements
Andreea A. Vărăşteanu, Matt J. Jarvis, Anastasia A. Ponomareva +8
The radial acceleration relation (RAR) is a fundamental relation linking baryonic and dark matter in galaxies by relating the observed acceleration derived from dynamics to the one…
The galaxy-environment connection revealed by constrained simulations
Catherine Gallagher, Tariq Yasin, Richard Stiskalek +2
The evolution of galaxies is known to be connected to their position within the large-scale structure and their local environmental density. We investigate the relative importance…
On the relationship between the cosmic web and the alignment of galaxies and AGN jets
Seoyoung Lyla Jung, I. H. Whittam, M. J. Jarvis +3
The impact of active galactic nuclei (AGN) on the evolution of galaxies explains the steep decrease in the number density of the most massive galaxies in the Universe. However, the…
Dark matter halo properties from spatially integrated HI flux profiles
Tariq Yasin, Harry Desmond
Resolved rotation curves (RCs) are our best probe of the dark matter distribution around individual galaxies. However their acquisition is resource-intensive, rendering them imprac…
On the consistency of rotation curves and spatially integrated HI flux profiles
Tariq Yasin, Harry Desmond
Resolved rotation curves (RCs) are the gold-standard measurements for inferring dark matter distributions in CDM and testing alternative theories of dynamics in galaxies. Howeve…
