Ultra-light dark matter

EGM Ferreira - The Astronomy and Astrophysics Review, 2021 - Springer
Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

Cosmological tests of gravity

PG Ferreira - Annual Review of Astronomy and Astrophysics, 2019 - annualreviews.org
Cosmological observations are beginning to reach a level of precision that allows us to test
some of the most fundamental assumptions in our working model of the Universe. One such …

Strong bound on canonical ultralight axion dark matter from the lyman-alpha forest

KK Rogers, HV Peiris - Physical Review Letters, 2021 - APS
We present a new bound on the ultralight axion (ULA) dark matter mass ma, using the
Lyman-alpha forest to look for suppressed cosmic structure growth: a 95% lower limit ma> …

New physics in light of the tension: An alternative view

S Vagnozzi - Physical Review D, 2020 - APS
The strong discrepancy between local and early-time (inverse distance ladder) estimates of
the Hubble constant H 0 could be pointing towards new physics beyond the concordance Λ …

Nonminimal dark sector physics and cosmological tensions

E Di Valentino, A Melchiorri, O Mena, S Vagnozzi - Physical Review D, 2020 - APS
We explore whether nonstandard dark sector physics might be required to solve the existing
cosmological tensions. The properties we consider in combination are (a) an interaction …
