Thermal Origin of Black Hole Quasinormal Modes
D. Giataganas, G. F. Giudice, A. Kehagias +2
When a black hole rings after a merger, it emits gravitational waves at characteristic frequencies known as quasinormal modes (QNMs). In the eikonal limit, these modes are governed…
Hunting Dark Matter with the Einstein Telescope
A. J. Iovino, M. Maggiore, N. Muttoni +1
Too light primordial black holes evaporate and are therefore strongly constrained by various bounds, e.g. Cosmic Microwave Background distortion. However, if they are formed strong…
Black Hole Mergers as the Fastest Photon Ring Scramblers
D. Giataganas, G. F. Giudice, A. Ianniccari +5
Black holes are the most efficient scramblers in nature. By mapping the instantaneous mass and angular momentum of two spinless black holes in a quasi-circular binary onto those of…
Dark Matter from Eternity
G. Franciolini, M. Peloso, A. Riotto
We propose that the totality of dark matter in the universe might ascribe its origin to one of the key properties of cosmological inflation, that it may be eternal: regions that at…
Standard Model Higgs Peaks: a Note on the Vacuum Instability during Inflation
G. Franciolini, A. Kehagias, A. Riotto
In the Standard Model, the Higgs potential develops an instability at high field values when the quartic self-coupling runs negative. Large quantum fluctuations during cosmic infla…
