Super heavy dark matter from inflationary Schwinger production
Mar Bastero-Gil, Paulo B. Ferraz, Lorenzo Ubaldi +1
We consider a simple setup with a dark sector containing dark electrons charged under an abelian gauge symmetry. We show that if the massless dark photon associated to the…
Non-thermal moduli production during preheating in -attractor inflation models
Khursid Alam, Mar Bastero-Gil, Koushik Dutta +1
Production of gravitationally coupled light moduli fields must be suppressed in the early universe, so that its decay products do not alter Big Bang Nucleosynthesis (BBN) predictio…
New solar X-ray constraints on keV Axion-Like Particles
Cyprien Beaufort, Mar Bastero-Gil, Tiffany Luce +1
The decay of Axion-Like Particles (ALPs) trapped in the solar gravitational field would contribute to the observed solar X-ray flux, hence constraining ALP models. We improve by on…
Thermal curvature perturbations in thermal inflation
Mar Bastero-Gil, Joaquim M. Gomes, João G. Rosa
We compute the power spectrum of super-horizon curvature perturbations generated during a late period of thermal inflation, taking into account fluctuation-dissipation effects resu…
