Axial Bianchi IX meets Gaia data
Thomas Schücker
The aim of the present work is two-fold: {\it(i)} Compute the drift of comoving extragalactic sources in axial Bianchi IX universes, in particular in those satisfying Einstein's eq…
Pushing spectral siren cosmology into the third-generation era: a blinded mock data challenge
Matteo Tagliazucchi, Michele Moresco, Alessandro Agapito +6
Gravitational wave (GW) spectral sirens offer a promising method for measuring cosmological parameters using GW data only - without relying on external redshift information such as…
Remembering George Smoot
John Berliner, Tom Broadhurst, Martin Bucher +31
George Smoot (1945-2025) was a major figure in observational cosmology, particularly through his role in the precision measurement of the CMB dipole and the discovery of the primor…
A Primer of Group Theory for Loop Quantum Gravity and Spin-foams
Pierre Martin-Dussaud
Calculations in Loop Quantum Gravity (LQG) and spin-foam theory rely heavily on the group theory of SU(2) and SL(2,C). Even though many monographs are devoted to this material, the…
Quantum theory for edge current and noise in two-dimensional topological superconductors
S. Pintus, A. Crépieux
We calculate the edge current and its fluctuations, i.e. noise, in a two-dimensional topological superconductor using the T-matrix and the Green function techniques. We show that t…
Semi-discrete optimal transport techniques for the compressible semi-geostrophic equations
David P. Bourne, Charlie P. Egan, Théo Lavier +1
We prove existence of weak solutions of the 3D compressible semi-geostrophic (SG) equations with compactly supported measure-valued initial data. These equations model large-scale…
