Limits of self-interacting neutrinos from the BAO and CMB phase shift
Abbé M. Whitford, Cullan Howlett, Tamara M. Davis +2
Neutrinos with Standard Model interactions free-stream in the early Universe, leaving a distinct phase shift in the pattern of baryon acoustic oscillations (BAO). When isolated, th…

DESIgning concordant distances in the age of precision cosmology: the impact of density fluctuations
David Camarena, Kylar Greene, John Houghteling +1
Discrepancies between distance measurements and CDM predictions reveal notable features in the distance-redshift relation, possibly suggesting the presence of an evolving dark…

Strong constraints on a simple self-interacting neutrino cosmology
David Camarena, Francis-Yan Cyr-Racine
Some cosmic microwave background (CMB) data allow a cosmological scenario in which the free streaming of neutrinos is delayed until close to matter-radiation equality. Interestingl…
