Galactic warps constrain equivalence-principle violation in the dark sector
Harry Desmond, Pedro G. Ferreira
Current measurements of the expansion of the Universe allow for the presence of evolving dark energy, distinct from a cosmological constant, with an equation of state that seems to…
MUSE-DARK IV. Comparing Dark Matter Densities to Star Formation Histories in 375 intermediate-z galaxies
B. I. Ciocan, N. F. Bouché, J. Fensch +5
(Abridged) Baryonic feedback is expected to transform cuspy dark-matter (DM) haloes into cores, but direct observational links between inner DM slopes and galaxy star-formation his…
Stars Would Remember a Recent Gravitational Transition: Testing G-step Resolutions of the Hubble Tension with Red Dwarfs
Jeremy Sakstein, Harry Desmond
We test the hypothesis that Newton's gravitational constant underwent a rapid transition approximately - ago, as proposed in some resolutions of the Hubble tens…
Two-rung ladder: from Tip of the Red Giant Branch and geometric anchors alone
Richard Stiskalek, Harry Desmond, Guilhem Lavaux
We infer the Hubble constant from the ~400 Extragalactic Distance Database hosts with a tip of the red giant branch (TRGB) distance, calibrated on the geometric anchors of th…
A reanalysis of the megamaser Hubble constant: from spot catalogues to peculiar velocities
Richard Stiskalek, Harry Desmond
The Hubble tension motivates careful scrutiny of the redshift-independent distances underpinning the local distance ladder. Water megamasers afford a purely geometric distance from…
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.…
Disentangling modified gravity and galaxy bias with field-level inference
Sophie Hoyland, Daniela Saadeh, Kazuya Koyama +1
We present a field-level inference framework for testing gravity with large-scale structure, exploiting the full information of the galaxy distribution. Traditional analyses based…
The age of the Universe from a large sample of the oldest Galactic stars
Indranil Banik, Thenujaya Kudakolawa Kaluarachchige, Stephen Cookson +1
We estimate the age of the Universe using the Xiang & Rix sample of 247,103 Milky Way stars with low-resolution spectroscopy from LAMOST DR7 and eDR3 parallaxes. Stellar age…
Evaluation of Population Initialization Methods for Genetic Programming-based Symbolic Regression
Lukas Kammerer, Gabriel Kronberger, Deaglan J. Bartlett +3
We analyze the effect of optimizing the initial population of genetic programming (GP) for symbolic regression (SR) on the accuracy and complexity of solutions. We compare three we…
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…
CMBolic: Symbolic emulators for the Cosmic Microwave Background. I. Lensing
David M. J. Vokrouhlicky, Constantinos Skordis, Deaglan J. Bartlett +2
We present the first installment of CMBolic: a suite of symbolic cosmic microwave background (CMB) emulators. In this instance, we emulate the CMB lensing potential power spectrum…
Precision constraints on stellar physics from main sequence detached eclipsing binaries
Mitchell T. Dennis, Harry Desmond, Jeremy Sakstein
We present a Bayesian framework to constrain {mass (), metallicity (), stellar age (), and the convective mixing length parameter ()} in main-sequence (MS) de…
Constraints on the gravitational potential from DESI DR2 BAO and its implications for the local void scenario
Indranil Banik, José Antonio Nájera, Harry Desmond
We constrain the difference in gravitational potential between our location and sources at using datasets at those redshifts. Our motivation is that the Hubble tens…
Guiding Multi-Objective Genetic Programming with Description Length Improves Symbolic Regression Solutions
Gabriel Kronberger, Fabricio Olivetti de Franca, Deaglan J. Bartlett +2
Symbolic regression with genetic programming (GPSR) may suffer from overfitting and structural bloat, especially when noise is present. In this paper we evaluate description length…
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…
Exhaustive Symbolic Integration: Integration by Differentiation and the Landscape of Symbolic Integrability
Harry Desmond
We introduce Exhaustive Symbolic Integration (ESI), a method that enumerates all symbolic functions up to a given complexity within a specified operator basis and determines wh…
The functional form of galaxy and halo luminosity and mass functions
Amelia Ford, Harry Desmond, Deaglan J Bartlett +1
The galaxy luminosity and stellar mass function (LF, SMF), and halo mass function (HMF), are fundamental quantities in astrophysics and crucial inputs to a range of astrophysical a…
