The First Billion Years project: dark matter haloes going from contraction to expansion and back again
Andrew J. Davis, Sadegh Khochfar, Claudio Dalla Vecchia
We study the effect of baryons on the inner dark matter profile of the first galaxies using the First Billion Years simulation between z=16-6 before secular evolution sets in. Usin…
Unravelling obese black holes in the first galaxies
Bhaskar Agarwal, Andrew J. Davis, Sadegh Khochfar +2
We predict the existence and observational signatures of a new class of objects that assembled early, during the first billion years of cosmic time: Obese Black-hole Galaxies (OBGs…
Virialization of high redshift dark matter haloes
Andrew Davis, Anson D'Aloisio, Priyamvada Natarajan
We present results of a study of the virial state of high redshift dark matter haloes in an N-body simulation. We find that the majority of collapsed, bound haloes are not virializ…
Spin and structural halo properties at high redshift in a LCDM Universe
Andrew J. Davis, Priyamvada Natarajan
In this paper, we examine in detail the key structural properties of high redshift dark matter haloes as a function of their spin parameter. We perform and analyze high resolution…
Angular momentum and clustering properties of early dark matter halos
Andrew J. Davis, Priyamvada Natarajan
In this paper we study the angular momentum properties of simulated dark matter halos at high redshift that likely host the first stars in the Universe. Calculating the spin distri…
