An improved cosmological bound on the thermal axion mass
Alessandro Melchiorri, Olga Mena, Anze Slosar
Relic thermal axions could play the role of an extra hot dark matter component in cosmological structure formation theories. By combining the most recent observational data we impr…
Cross-correlation studies as a probe of reionization physics
Anze Slosar, Asantha Cooray, Joseph Silk
The process of reionization is now believed to have proceeded in an orchestrated manner beginning with UV photons emitted by high redshift galaxies containing a large fraction of P…
New Constraints on Oscillations in the Primordial Spectrum of Inflationary Perturbations
Jan Hamann, Laura Covi, Alessandro Melchiorri +1
We revisit the problem of constraining steps in the inflationary potential with cosmological data. We argue that a step in the inflationary potential produces qualitatively similar…
