Gravitational Waves from Magnetars

Chris Kouvaris

We study the emission of gravitational waves produced by the magnetosphere of magnetars. We argue that several features in the spectrum could facilitate the identification of that…

Radio Signals from Axion Star-Neutron Star Binaries

Chris Kouvaris, Tao Liu, Kun-Feng Lyu

Axion stars could form binaries with neutron stars. Given the extremely strong external magnetic field exhibited by individual neutron stars, there can be a substantial conversion…

Non-Primordial Solar Mass Black Holes

Chris Kouvaris, Peter Tinyakov, Michel H. G. Tytgat

We propose a mechanism that can convert a sizeable fraction of neutron stars into black holes with mass , too light to be produced via standard stellar evolution. We…

Dark stars: gravitational and electromagnetic observables

Andrea Maselli, Pantelis Pnigouras, Niklas Gønlund Nielsen +2

Theoretical models of self-interacting dark matter represent a promising answer to a series of open problems within the so-called collisionless cold dark matter (CCDM) paradigm. In…

High Energy Positrons and Gamma Radiation from Decaying Constituents of a two-component Dark Atom Model

K. Belotsky, M. Khlopov, C. Kouvaris +1

We study a two component dark matter candidate inspired by the Minimal Walking Technicolor model. Dark matter consists of a dominant SIMP-like dark atom component made of bound sta…

The Dark Side of Neutron Stars

Chris Kouvaris

We review severe constraints on asymmetric bosonic dark matter based on observations of old neutron stars. Under certain conditions, dark matter particles in the form of asymmetric…
