The swallowed spike: the formation of light primordial black hole structures around heavy seeds
Agnese Tolino, Francesca Scarcella, Bradley J. Kavanagh +2
Spikes are steep enhancements in the dark matter (DM) distribution around a heavy compact object. If the compact object is primordial, and the bulk of the DM is also composed of (l…
NAJADS: a self-contained framework for the direct determination of astrophysical J-factors
Anna Balaudo, Francesca Calore, Valentina De Romeri +1
Cosmological simulations play a pivotal role in understanding the properties of the dark matter (DM) distribution in both galactic and galaxy-cluster environments. The characteriza…
Conservative upper limits on WIMP annihilation cross section from Fermi-LAT γ-rays
Francesca Calore, Valentina De Romeri, Fiorenza Donato
The spectrum of an isotropic extragalactic γ-ray background (EGB) has been measured by the Fermi-LAT telescope at high latitudes. Two new models for the EGB are derived from the su…
Evolution and instabilities of disks harboring super massive black holes
Anna Curir, Valentina de Romeri, Giuseppe Murante
The bar formation is still an open problem in modern astrophysics. In this paper we present numerical simulation performed with the aim of analyzing the growth of the bar instabili…
