Thermal production of astrophobic axions
Journal of High Energy PhysicsHot axions are produced in the early Universe via their interactions with Standard Model particles, contributing to dark radiation commonly parameterized as ∆N eff.Marcin Badziak, Keisuke Harigaya, Michał Łukawski, Robert Ziegler +3 moredoaj +1 more sourceEuclid preparation. XCII. Controlling angular systematics in the Euclid spectroscopic galaxy sample [PDF]
Astronomy & AstrophysicsWe present the strategy used to identify and mitigate potential sources of angular systematics in the spectroscopic galaxy survey, and we quantify their impact on galaxy clustering measurements and cosmological parameter estimation. We first surveyed the Euclid Collaboration P. Monaco, M. Y. Elkhashab, B. Granett, J. Salvalaggio, E. Sefusatti, C. Scarlata, B. Zabelle, M. Béthermin, S. Bruton, C. Carbone, S. D. L. Torre, S.

Journal of High Energy PhysicsRecently, two of the present authors showed that even when the axion momentum is much smaller than its mass, the axion can still behave like radiation if its energy density greatly exceeds the maximum potential energy set by the cosine-type potential.
