Abstract: We have considered the prospects for measuring the cross Warm Dark Matter (WDM) power spectrum of the redshifted HI 21-cm signal and the Lyman-$\alpha$ forest and thereby constraining WDM mass using observations with upcoming radio-interferometers… read more here.

Abstract: We use a semi-analytic model, Delphi, which jointly tracks the dark matter and baryonic assembly of high-redshift (z ≃ 4-20) galaxies to gain insight on the number density of dicollapse black hole (DCBH) hosts in… read more here.

Abstract: We use a pair of high-resolution N-body simulations implementing two dark matter models, namely the standard cold dark matter (CDM) cosmogony and a warm dark matter (WDM) alternative where the dark matter particle is a… read more here.

DOI: 10.1093/mnras/stz327
Abstract: In this third paper of the series, we investigate the effects of warm dark matter with a particle mass of $m_\mathrm{WDM}=3\,\mathrm{keV}$ on the smallest galaxies in our Universe. We present a sample of 21 hydrodynamical… read more here.

DOI: 10.3390/universe7120462
Abstract: Warm dark matter particles with masses in the keV range have been linked with the large group representations in gauge theories through a high number of species at decoupling. In this paper, we address WDM… read more here.
