DOI: 10.1007/s10714-025-03451-9

Abstract: The latest observations from the LIGO-Virgo indicated the existence of mass-gap region astrophysical objects. This is a rather sensational observation and there are two possibilities for the nature of these mass-gap region astrophysical objects, these… read more here.

DOI: 10.1093/mnras/stab2136

Abstract: Recent detections of gravitational waves from mergers of neutron stars (NSs) and black holes (BHs) in the low and high-end mass gap regimes pose a puzzle to standard stellar and binary evolution theory. Mass-gap mergers… read more here.

Abstract: In this work we study static neutron stars in the context of several inflationary models which are popular in cosmology. These inflationary models are non-minimally coupled scalar theories which yield a viable inflationary phenomenology in… read more here.

Abstract: The identity of a compact astronomical object in the Milky Way is unclear Astrophysical compact objects come in two varieties: neutron stars and black holes. Created when massive stars die and their cores collapse, neutron… read more here.
