DOI: 10.1088/1475-7516/2025/09/017
Abstract: In this work we explore the potential for Neutron Stars (NSs) at the Galactic center and Population III stars to constrain bosonic Asymmetric Dark Matter (ADM). We demonstrate that for NSs in an environment of… read more here.

DOI: 10.1093/mnras/stab1953
Abstract: The first stars in the Universe, the so-called Population III stars, form in small dark matter minihaloes with virial temperatures Tvir < 104 K. Cooling in these minihaloes is dominated by molecular hydrogen (H2), and so… read more here.

DOI: 10.1093/mnras/stab2592
Abstract: We calculate the neutrino signal from Population III supermassive star (SMS) collapse using a neutrino transfer code originally developed for core-collapse supernovae and massive star collapse. Using this code, we are able to investigate the… read more here.

DOI: 10.1093/mnras/stad1196
Abstract: Recent data from the James Webb Space Telescope suggest that there are realistic prospects for detecting the earliest generation of stars at redshift ∼20. These metal-poor, gaseous Population III (Pop III) stars are likely in… read more here.

Population III star formation in the presence of turbulence, magnetic fields and ionizing radiation feedback

DOI: 10.1093/mnras/staf803
Abstract: Turbulence, magnetic fields and radiation feedback are key components that shape the formation of stars, especially in the metal-free environments at high redshifts where Population III stars form. Yet no 3D numerical simulations exist that… read more here.

DOI: 10.1093/mnrasl/slaf043
Abstract: The masses of Population III stars are largely unconstrained since no simulations exist that take all relevant primordial star formation physics into account. We perform the first suite of radiation magnetohydrodynamics (RMHD) simulations of Population… read more here.

DOI: 10.1103/physrevd.110.023017
Abstract: We probe the astrophysical gravitational-wave background resulting from compact binary coalescences, focusing on population III binary black holes. We exploit results of state-of-the-art simulations on the evolution of population I-II and III binaries, considering a… read more here.

Effective model for the 21-cm signal with population III stars
Sign Up to like & getrecommendations! Published in 2024 at "Physical Review D"
DOI: 10.1103/physrevd.111.083503
Abstract: Observations of the 21-cm signal are opening a window to the cosmic-dawn epoch, when the first stars formed. These observations are usually interpreted with semi-numerical or hydrodynamical simulations, which are often computationally intensive and inflexible… read more here.
