Off-centre supermassive black holes in bright central galaxies
Aline Chu, Pierre Boldrini, Joe Silk
Supermassive black holes (SMBHs) are believed to reside at the centre of massive galaxies such as brightest cluster galaxies (BCGs). However, as BCGs experienced numerous galaxy me…
Massive black hole assembly in nuclear star clusters
Konstantinos Kritos, Emanuele Berti, Joseph Silk
Nuclear star clusters, which fragment into metal-poor stars in situ at the centers of protogalaxies, provide ideal environments for the formation of intermediate-mass black holes w…
Improved stellar limits on a light CP-even scalar
Shyam Balaji, P. S. Bhupal Dev, Joseph Silk +1
We derive improved stellar luminosity limits on a generic light CP-even scalar field mixing with the Standard Model (SM) Higgs boson from the supernova SN1987A, the Sun, red gi…
Primordial black hole mergers from three-body interactions
Gabriele Franciolini, Konstantinos Kritos, Emanuele Berti +1
Current gravitational-wave observations set the most stringent bounds on the abundance of primordial black holes (PBHs) in the solar mass range. This constraint, however, inherentl…
Induced gravitational waves from slow-roll inflation after an enhancing phase
Shyam Balaji, Guillem Domenech, Joseph Silk
The primordial spectrum of fluctuations may present a large peak as a result of enhancing features during inflation. This may include, but is not limited to, bumps in the inflaton'…
Cooling of Neutron Stars admixed with Light Dark Matter: a case study
M. Ángeles Pérez-García, H. Grigorian, C. Albertus +2
Neutron Stars (NSs) are born as hot, lepton-rich objects that evolve according to the standard paradigm through subsequent stages where they radiate the excess of energy by emittin…
