Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/sty2160

Abstract: The standard model of cosmology, {\Lambda}CDM, is the simplest model that matches the current observations, but it relies on two hypothetical components, to wit, dark matter and dark energy. Future galaxy surveys and cosmic microwave… read more here.

Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/sty271

Abstract: The cosmic microwave background (CMB) places strong constraints on models of dark matter (DM) that deviate from standard cold DM (CDM), and on initial conditions beyond the scalar adiabatic mode. Here, the full \textit{Planck} data… read more here.

Published in 2020 at "Physical Review D"

DOI: 10.1103/physrevd.101.083525

Abstract: The weak gravity conjecture imposes severe constraints on natural inflation. A trans-Planckian axion decay constant can be realized only if the potential exhibits an additional (subdominant) modulation with sub-Planckian periodicity. The resulting wiggles in the… read more here.

Published in 2021 at "Physical Review D"

DOI: 10.1103/physrevd.103.083515

Abstract: Gravitational wave bursts with memory (BWMs) can generate measurable, long-lived frequency shifts and permanent angular deflections in distant sources of light. These perturbations vary across the sky with a characteristic spatial pattern and evolve slowly… read more here.
