Constraints on the properties of warm dark matter using the satellite galaxies of the Milky Way
Oliver Newton, Matteo Leo, Marius Cautun +5
The satellite galaxies of the Milky Way (MW) are effective probes of the underlying dark matter (DM) substructure, which is sensitive to the nature of the DM particle. In particula…
Constraining structure formation using EDGES
Matteo Leo, Tom Theuns, Carlton M. Baugh +2
The experiment to detect the global epoch of reionization signature (EDGES) collaboration reported the detection of a line at 78MHz in the sky-averaged spectrum due to neutral hydr…
Realistic simulations of galaxy formation in f(R) modified gravity
Christian Arnold, Matteo Leo, Baojiu Li
We have carried out a set of cosmological hydrodynamical simulations that follow galaxy formation in modified gravity models. Our simulations employ the Illustris-TNG full p…
High-redshift test of gravity using enhanced growth of small structures probed by the neutral hydrogen distribution
Matteo Leo, Christian Arnold, Baojiu Li
Future 21 cm intensity mapping surveys such as SKA can provide precise information on the spatial distribution of the neutral hydrogen (HI) in the post-reionization epoch. This inf…
N-body simulations of structure formation in thermal inflation cosmologies
Matteo Leo, Carlton M. Baugh, Baojiu Li +1
Thermal inflation models (which feature two inflationary stages) can display damped primordial curvature power spectra on small scales which generate damped matter fluctuations. Fo…
A new smooth- space filter approach to calculate halo abundances
Matteo Leo, Carlton M. Baugh, Baojiu Li +1
We propose a new filter, a smooth- space filter, to use in the Press-Schechter approach to model the dark matter halo mass function which overcomes shortcomings of other filters…
Nonlinear growth of structure in cosmologies with damped matter fluctuations
Matteo Leo, Carlton M. Baugh, Baojiu Li +1
We investigate the nonlinear evolution of structure in variants of the standard cosmological model which display damped density fluctuations relative to cold dark matter (e.g. in w…
The Effect of Thermal Velocities on Structure Formation in N-body Simulations of Warm Dark Matter
Matteo Leo, Carlton M. Baugh, Baojiu Li +1
We investigate the impact of thermal velocities in N-body simulations of structure formation in warm dark matter models. Adopting the commonly used approach of adding thermal veloc…
Reionization during the dark ages from a cosmic axion background
Carmelo Evoli, Matteo Leo, Alessandro Mirizzi +1
Recently it has been pointed out that a cosmic background of relativistic axion-like particles (ALPs) would be produced by the primordial decays of heavy fields in the post-inflati…
