Modified recombination and the Hubble tension
Seyed Hamidreza Mirpoorian, Karsten Jedamzik, Levon Pogosian
We investigate the extent to which modifying the ionization history at cosmological recombination can relieve the Hubble tension, taking into account all relevant datasets and cons…
Extending MGCAMB tests of gravity to nonlinear scales
Zhuangfei Wang, Daniela Saadeh, Kazuya Koyama +4
Modified Growth with {\tt CAMB} ({\tt MGCAMB}) is a patch for the Einstein-Boltzmann solver {\tt CAMB} for cosmological tests of gravity. Until now, {\tt MGCAMB} was limited to sca…
A consistency test of the cosmological model at the epoch of recombination using DESI BAO and Planck measurements
Levon Pogosian, Gong-Bo Zhao, Karsten Jedamzik
The value of the Hubble constant determined from CMB and BAO measurements is directly dependent on the sound horizon at the photon-baryon decoupling. There has been significant int…
Disentangling modified gravity from a dark force with gravitational redshift
Sveva Castello, Zhuangfei Wang, Lawrence Dam +2
The standard approach to test for deviations from general relativity on cosmological scales is to combine measurements of the growth rate of structure with gravitational lensing. I…
