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…
