Screened Scalar Hair and the Weak-Lensing Separation of Black Holes from Neutron Stars in Quadratic Gravity
Yashmitha Kumaran, Ilídio Lopes
Quadratic gravity carries a massive scalar degree of freedom, the scalaron, whose finite range screens its influence on the geometry outside a compact object. We show th…
Weak gravitational lensing by a dark-matter-admixed neutron star: a self-consistent two-fluid halo and the Gauss--Bonnet deflection angle
Yashmitha Kumaran, Ilídio Lopes
We compute the weak gravitational deflection of light by a neutron star that carries a self-consistent dark-matter component, in the regime in which the dark matter forms an "exten…
Production of Gravitational Waves in the Early Universe From turbulence triggered by first-order phase transitions
Yashmitha Kumaran
This project is aimed at studying the first-order phase transitions, that is presumed to have ensued in the early universe, and its consequences on the primordial gravitational wav…
Radial oscillations of pulsating neutron stars: The UCIa equation-of-state case
G. Panotopoulos, A. Övgün, T. Iqbal +2
Radial oscillations provide a clean dynamical test of the high-density stiffness of neutron-star equations of state. We study spherically symmetric pulsations of nonrotating relati…
