EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade
R. Alves Batista, M. A. Amin, G. Barenboim +134
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…
When FIMPs Decay into Neutrinos: The Story
Alexey Boyarsky, Maksym Ovchynnikov, Nashwan Sabti +1
The existence of feebly interacting massive particles (FIMPs) could have significant implications on the effective number of relativistic species in the early Univ…
New Constraints on the Mass of Fermionic Dark Matter from Dwarf Spheroidal Galaxies
James Alvey, Nashwan Sabti, Victoria Tiki +7
Dwarf spheroidal galaxies are excellent systems to probe the nature of fermionic dark matter due to their high observed dark matter phase-space density. In this work, we review, re…
First Constraints on Small-Scale Non-Gaussianity from UV Galaxy Luminosity Functions
Nashwan Sabti, Julian B. Muñoz, Diego Blas
UV luminosity functions provide a wealth of information on the physics of galaxy formation in the early Universe. Given that this probe indirectly tracks the evolution of the mass…
An Extended Analysis of Heavy Neutral Leptons during Big Bang Nucleosynthesis
Nashwan Sabti, Andrii Magalich, Anastasiia Filimonova
Heavy Neutral Leptons (HNLs) are strongly motivated by theory due to their capability of simultaneously explaining the observed phenomena of dark matter, neutrino oscillations and…
Refined Bounds on MeV-scale Thermal Dark Sectors from BBN and the CMB
Nashwan Sabti, James Alvey, Miguel Escudero +2
New light states thermally coupled to the Standard Model plasma alter the expansion history of the Universe and impact the synthesis of the primordial light elements. In this work,…
