Properties of Local Group galaxies in hydrodynamical simulations of sterile neutrino dark matter cosmologies
Mark R. Lovell, Sownak Bose, Alexey Boyarsky +10
We study galaxy formation in sterile neutrino dark matter models that differ signifi- cantly from both cold and from `warm thermal relic' models. We use the EAGLE code to carry out…
Addressing the too big to fail problem with baryon physics and sterile neutrino dark matter
Mark R. Lovell, Violeta Gonzalez-Perez, Sownak Bose +4
N-body dark matter simulations of structure formation in the CDM model predict a population of subhalos within Galactic halos that have higher central densities than inferred fo…
The Extraordinary Amount of Substructure in the Hubble Frontier Fields Cluster Abell 2744
M. Jauzac, D. Eckert, J. Schwinn +21
We present a joint optical/X-ray analysis of the massive galaxy cluster Abell 2744 (z=0.308). Our strong- and weak-lensing analysis within the central region of the cluster, i.e.,…
Reionisation in sterile neutrino cosmologies
Sownak Bose, Carlos S. Frenk, Hou Jun +2
We investigate the process of reionisation in a model in which the dark matter is a warm elementary particle such as a sterile neutrino. We focus on models that are consistent with…
Weak lensing by galaxy troughs with modified gravity
Alexandre Barreira, Sownak Bose, Baojiu Li +1
We study the imprints that theories of gravity beyond GR can leave on the lensing signal around line of sight directions that are predominantly halo-underdense (called troughs) and…
Substructure and galaxy formation in the Copernicus Complexio warm dark matter simulations
Sownak Bose, Wojciech A. Hellwing, Carlos S. Frenk +6
We use the Copernicus Complexio (COCO) high resolution -body simulations to investigate differences in the properties of small-scale structures in the standard cold dark matter…
The Mass-Concentration-Redshift Relation of Cold and Warm Dark Matter Halos
Aaron D. Ludlow, Sownak Bose, Raúl E. Angulo +5
We use a suite of cosmological simulations to study the mass-concentration-redshift relation, , of dark matter halos. Our simulations include standard -cold dark m…
RAY-RAMSES: a code for ray tracing on the fly in N-body simulations
Alexandre Barreira, Claudio Llinares, Sownak Bose +1
We present a ray tracing code to compute integrated cosmological observables on the fly in AMR N-body simulations. Unlike conventional ray tracing techniques, our code takes full a…
