On the Late-Time Evolution of Velocity-Dependent Self-Interacting Dark Matter Halos
Sophia Gad-Nasr, Kimberly K. Boddy, Manoj Kaplinghat +2
We study the evolution of isolated self-interacting dark matter (SIDM) halos that undergo gravothermal collapse and are driven deep into the short-mean-free-path regime. We assume…
Binary systems in massive scalar-tensor theories: Next-to-leading order gravitational wave phase from effective field theory
Robin Fynn Diedrichs, Daniel Schmitt, Laura Sagunski
Neutron star binaries and their associated gravitational wave signal facilitate precision tests of General Relativity. Any deviation of the detected gravitational waveform from Gen…
Fermion Proca Stars: Vector Dark Matter Admixed Neutron Stars
Cédric Jockel, Laura Sagunski
Dark matter could accumulate around neutron stars in sufficient amounts to affect their global properties. In this work, we study the effect of a specific model for dark matter --…
R-modes as a New Probe of Dark Matter in Neutron Stars
Swarnim Shirke, Suprovo Ghosh, Debarati Chatterjee +2
In this work, we perform the first systematic investigation of effects of the presence of dark matter on -mode oscillations in neutron stars (NSs). Using a self-interacting dark…
Tidal Deformability of Fermion-Boson Stars: Neutron Stars Admixed with Ultra-Light Dark Matter
Robin Fynn Diedrichs, Niklas Becker, Cédric Jockel +3
In this work we investigate the tidal deformability of a neutron star admixed with dark matter, modeled as a massive, self-interacting, complex scalar field. We derive the equation…
Supercool exit: Gravitational waves from QCD-triggered conformal symmetry breaking
Laura Sagunski, Philipp Schicho, Daniel Schmitt
Classically conformal Standard Model extensions predict an intriguing thermal history of the early universe. In contrast to the common paradigm, the onset of the electroweak phase…
