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…
Cosmology from Clustering of Continuum Galaxies
Jacobo Asorey, Catherine L. Hale, Sebastian von Hausegger +6
The distribution of radio continuum galaxies is a useful, fast, and accessible probe of the matter distribution in the Universe, enlightening us about the Universe's initial condit…
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…
The kinematic contribution to the cosmic number count dipole
J. D. Wagenveld, S. von Hausegger, H-R. Klöckner +1
Measurements of the number count dipole with large surveys have shown amplitudes in tension with kinematic predictions based on the observed Doppler dipole of the cosmic microwave…
The expected kinematic matter dipole is robust against source evolution
Sebastian von Hausegger
Recent measurements using catalogues of quasars and radio galaxies have shown that the dipole anisotropy in the large-scale distribution of matter is about twice as large as is exp…
