Revisiting observational constraints on coupled exponential quintessence with energy and momentum transfers: degeneracy with massive neutrinos

Jose Beltrán Jiménez, Kiyotomo Ichiki, Xiaolin Liu +2

We investigate the impact of massive neutrinos on cosmological models in which dark energy, described by a quintessence scalar field with an exponential potential, interacts wi…

Is the NANOGrav detection evidence of resonant particle creation during inflation?

M. R. Gangopadhyay, V. V. Godithi, K. Ichiki +5

We show that the recently reported cosmic gravitational wave background by the NANOGrav 15-year collaboration may be the result of resonant particle creation during inflation. For…
