The survival of dark matter halos in the cluster Cl0024+16
Priyamvada Natarajan, Jean-Paul Kneib, Ian Smail +5
Theories of structure formation in a cold dark matter dominated Universe predict that massive clusters of galaxies assemble from the hierarchical merging of lower mass subhalos. Ex…
Consequences of dark matter self-annihilation for galaxy formation
Priyamvada Natarajan, Darren Croton, Gianfranco Bertone
Galaxy formation requires a process that continually heats gas and quenches star formation in order to reproduce the observed shape of the luminosity function of bright galaxies. T…
Where is the matter in the Merging Cluster Abell 2218?
Árdís Elíasdóttir, Marceau Limousin, Johan Richard +6
We present a parametric strong lensing model of the cluster Abell 2218 based on HST ACS data. We constrain the lens model using 8 previously known multiply imaged systems, of which…
The evolution of massive black hole seeds
M. Volonteri, G. Lodato, P. Natarajan
We investigate the evolution of high redshift seed black hole masses at late times and their observational signatures. The massive black hole seeds studied here form at extremely h…
Probing the truncation of galaxy dark matter halos in high density environments from hydrodynamical N-body simulations
Marceau Limousin, Jesper Sommer-Larsen, Priyamvada Natarajan +1
We analyze high resolution, N-body hydrodynamical simulations of fiducial galaxy clusters to probe tidal stripping of the dark matter subhalos. These simulations include a prescrip…
How robust are the constraints on cosmology and galaxy evolution from the lens-redshift test?
Pedro R. Capelo, Priyamvada Natarajan
The redshift distribution of galaxy lenses in known gravitational lens systems provides a powerful test that can potentially discriminate amongst cosmological models. However, appl…
