Formation Histories of Dwarf Galaxies in the Local Group

Massimo Ricotti, Nickolay Y. Gnedin

We compare the properties of dwarf galaxies in the Local Group with the simulated galaxies formed before reionization in a cosmological simulation of unprecedented spatial and mass…

On the Origin of Dark Matter Cores in Dwarf Galaxies

Massimo Ricotti, Mark I. Wilkinson

In this paper, we study the dynamical stability and time evolution of the central dark matter cores of low-mass (about 10^8-10^9 M_solar) galactic haloes found in recent cold dark…

Reionisation: the role of Globular Clusters

Massimo Ricotti

In this talk I discuss the role of proto-globular clusters as the dominant sources of radiation that reionised hydrogen in the intergalactic medium (IGM) at redshift z~6. Observati…

X-ray Preionisation Powered by Accretion on the First Black Holes. II: Cosmological Simulations and Observational Signatures

Massimo Ricotti, Jeremiah P. Ostriker, Nickolay Y. Gnedin

We use cosmological simulations to study the X-ray ionisation and heating of the intergalactic medium by an early population of accreting black holes. By considering observational…

Have we detected one of the sources responsible for an early reionisation of the Universe?

Massimo Ricotti, Martin G. Haehnelt, Max Pettini +1

In a recent paper Pell'o et al. have reported a candidate z=10 galaxy, A1835#1916, which was found in a near-infrared survey of the central regions of the gravitational lensing clu…
