Observing dark matter clumps and asteroid-mass primordial black holes in the solar system with gravimeters and GNSS networks
Bruno Bertrand, Michal Cuadrat-Grzybowski, Pascale Defraigne +2
In this proceedings, we study the possible gravitational impact of primordial black holes (PBHs) or dark matter (DM) clumps on GNSS satellite orbits and gravimeter measurements. It…
Can Primordial Black Holes form in the Standard Model ?
Ioanna Stamou, Sebastien Clesse
We investigate the viability of primordial black hole (PBH) formation in the Standard Model (SM) in a scenario that does not rely on specific inflationary features or any exotic ph…
Analysis of the subsolar-mass black hole candidate SSM200308 from the second part of the third observing run of Advanced LIGO-Virgo
Marine Prunier, Gonzalo Morrás, José Francisco Nuño Siles +3
A follow-up of a subsolar black hole candidate identified in the second part of the third observing run of the LIGO-Virgo-KAGRA collaboration is carried out. With a search signal-t…
Primordial black holes and their gravitational-wave signatures
Eleni Bagui, Sebastien Clesse, Valerio De Luca +17
In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain…
Primordial Black Holes without fine-tuning from a light stochastic spectator field
Ioanna Stamou, Sebastien Clesse
We investigate a mechanism of primordial black hole (PBH) formation that avoids any dependence on specific inflationary features or exotic physics. In this scenario, the required l…
A Joint Fermi-GBM and Swift-BAT Analysis of Gravitational-Wave Candidates from the Third Gravitational-wave Observing Run
C. Fletcher, J. Wood, R. Hamburg +1696
We present Fermi Gamma-ray Burst Monitor (Fermi-GBM) and Swift Burst Alert Telescope (Swift-BAT) searches for gamma-ray/X-ray counterparts to gravitational wave (GW) candidate even…
