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 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…
A fast semi-discrete optimal transport algorithm for a unique reconstruction of the early Universe
Bruno Lévy, Roya Mohayaee, Sebastian von Hausegger
We leverage powerful mathematical tools stemming from optimal transport theory and transform them into an efficient algorithm to reconstruct the fluctuations of the primordial dens…
A Test of the Cosmological Principle with Quasars
Nathan Secrest, Sebastian von Hausegger, Mohamed Rameez +3
We study the large-scale anisotropy of the Universe by measuring the dipole in the angular distribution of a flux-limited, all-sky sample of 1.36 million quasars observed by the Wi…
From top-hat masking to smooth transitions: P-filter and its application to polarized microwave sky maps
Hao Liu, James Creswell, Sebastian von Hausegger +1
In CMB science, the simplest idea to remove a contaminated sky region is to multiply the sky map with a mask that is 0 for the contaminated region and 1 elsewhere, which is also ca…
