Tidal deformability of fermion-boson stars: Neutron stars admixed with ultralight dark matter [PDF]
Physical Review D, 2023 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.

Strongly interacting matter exhibits deconfined behavior in massive neutron stars [PDF]
Nature Communications, 2023 Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear matter melts into deconfined quark matter, liberating its constituent quarks and gluons.

On the Sound Speed in Neutron Stars [PDF]
Astrophysical Journal Letters, 2022 Determining the sound speed c s in compact stars is an important open question with numerous implications on the behavior of matter at large densities and hence on gravitational-wave emission from neutron stars.

Dark matter admixed neutron stars [PDF]
Physical Review D, 2021 Neutron stars could contain a mixture of ordinary nuclear matter and dark matter, such that dark matter could influence observable properties of the star, such as its mass and radius.

Holographic modeling of nuclear matter and neutron stars [PDF]
The European Physical Journal C, 2021 I review holographic models for (dense and cold) nuclear matter, neutron stars, and their mergers. I start by a brief general discussion on current knowledge of cold QCD matter and neutron stars, and go on discussing various approaches to model cold ...

The Mass Distribution of Neutron Stars in Gravitational-wave Binaries [PDF]
Astrophysical Journal Letters, 2021 The discovery of two neutron star–black hole coalescences by LIGO and Virgo brings the total number of likely neutron stars observed in gravitational waves to six.

Physical Review D, 2022 The fundamental nature of dark matter is entirely unknown. A compelling candidate is Twin Higgs mirror matter, invisible hidden-sector cousins of the Standard Model particles and forces. This predicts mirror neutron stars made entirely of mirror nuclear matter. We find their structure using realistic equations of state, robustly modified based on first-
