On the Minimum Radius of Very Massive Neutron Stars
Prospects of establishing the radii of massive neutron stars in PSR J1614-2230 and PSR J0740+6620 from NICER and Chandra observatories hold the potential to constrain the equation of state (EoS) […]

Time of flight and supernova progenitor effects on the neutrino halo
We argue that the neutrino halo, a population of neutrinos that have undergone direction-changing scattering in the stellar envelope of a core-collapse supernova (CCSNe), is sensitive to neutrino emission history […]

Consequences of neutrino self-interactions for weak decoupling and big bang nucleosynthesis
We calculate and discuss the implications of neutrino self-interactions for the physics of weak decoupling and big bang nucleosynthesis (BBN) in the early universe. In such neutrino-sector extensions of the […]

The R-process Alliance: The Peculiar Chemical Abundance Pattern of RAVE J183013.5−455510
We report on the spectroscopic analysis of RAVE J183013.5-455510, an extremely metal-poor star, highly enhanced in CNO, and with discernible contributions from the rapid neutron-capture process. There is no evidence […]

Origin of sterile neutrino dark matter via secret neutrino interactions with vector bosons
We apply for the first time fission yields determined across the chart of nuclides from the macroscopic-microscopic theory of the Finite Range Liquid Drop Model to simulations of rapid neutron […]
