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…
On the survival of dark matter spikes: Stellar and compact-object perturbations
Theophanes K. Karydas, Francesca Scarcella, Bradley J. Kavanagh +1
Establishing realistic expectations for the dark matter (DM) distribution near a supermassive black hole (BH) is essential for assessing environmental imprints on gravitational wav…
Hints of Dark Matter Spikes in Low-mass X-ray Binaries: a critical assessment
Francesca Scarcella, Bradley J. Kavanagh
Three black-hole low-mass X-ray binaries (LMXBs) in the Milky Way show rates of period decay which cannot be easily explained by standard mechanisms. Recently, it has been claimed…
CMB bounds on primordial black holes with dark matter mini-halos: the role of radiative feedback
Francesca Scarcella
Observations of the cosmic microwave background constrain the abundance of primordial black holes, as these would accrete gas and inject energy into the cosmological medium. We hav…
Feedback in the dark: a critical examination of CMB bounds on primordial black holes
Dominic Agius, Rouven Essig, Daniele Gaggero +3
If present in the early universe, primordial black holes (PBHs) will accrete matter and emit high-energy photons, altering the statistical properties of the {Cosmic Microwave Backg…
Black Hole Phenomenology and Dark Matter Searches
Francesca Scarcella
Motivated by recent detections of black hole binary systems through gravitational waves, in this thesis we discuss two complementary channels for the observation of Primordial Blac…
Dancing in the dark: detecting a population of distant primordial black holes
Matteo Martinelli, Francesca Scarcella, Natalie B. Hogg +3
Primordial black holes (PBHs) are compact objects proposed to have formed in the early Universe from the collapse of small-scale over-densities. Their existence may be detected fro…
Multi-wavelength detectability of isolated black holes in the Milky Way
Francesca Scarcella, Daniele Gaggero, Riley Connors +3
Isolated black holes in our Galaxy have eluded detection so far. We present here a comprehensive study on the detectability of isolated stellar-mass astrophysical black holes that…
Charged lepton flavour violation from low scale seesaw neutrinos
V. De Romeri, M. J. Herrero, X. Marcano +1
In the work presented here, we have studied the impact of right handed neutrinos, which are introduced to account for the evidence of neutrino masses, on charged lepton flavour vio…
Lepton flavor violating Z decays: A promising window to low scale seesaw neutrinos
V. De Romeri, M. J. Herrero, X. Marcano +1
In this paper we study the Lepton Flavor Violating boson decays and in the context of low scale seesaw models with new heavy Majorana neutrinos whose mass…
