Bayesian analysis of the spin distribution of LIGO/Virgo black holes / García-Bellido, Juan (Madrid, IFT) ; Nuño Siles, José Francisco (Madrid, IFT) ; Ruiz Morales, Ester (Madrid, Polytechnic U.)
Gravitational wave detection from binary black hole (BBH) inspirals has become routine thanks to the LIGO/Virgo interferometers. The nature of these back holes remains uncertain. [...]

 Hearing the forest for the trees: understanding LIGO/Virgo's plurality of singularities / Farr, Benjamin Frederick (speaker) (University of Oregon (US))
Before the start of their current and fourth observing run (O4), the LIGO and Virgo detectors had already collected an impressive census of compact binary mergers in the local universe. By the end of O2 in August 2017 the LIGO Scientific Collaboration and Virgo Collaboration claimed a total of 10 binary black hole mergers and one binary neutron star merger. [...]

Seven Hints for Primordial Black Hole Dark Matter / Clesse, Sebastien (Louvain U., CP3 ; Namur U. ; RWTH Aachen U.) ; García-Bellido, Juan (Madrid, IFT ; CERN)
Seven observations point towards the existence of primordial black holes (PBH), constituting the whole or an important fraction of the dark matter in the Universe: the mass and spin of black holes detected by Advanced LIGO/VIRGO, the detection of micro-lensing events of distant quasars and stars in M31, the non-detection of ultra-faint dwarf satellite galaxies with radius below 15 parsecs, evidences for core galactic dark matter profiles, the correlation between X-ray and infrared cosmic backgrounds, and the existence of super-massive black holes very early in the Universe's history. Some of these hints are newly identified and they are all intriguingly compatible with the re-constructed broad PBH mass distribution from LIGO events, peaking on PBH mass $m_{\rm PBH} \approx 3 M_\odot$ and passing all other constraints on PBH abundances.

Detecting the Stochastic Gravitational Wave Background from Primordial Black Hole Formation / Clesse, Sebastien (Louvain U.) ; García-Bellido, Juan (CSIC, Madrid ; CERN) ; Orani, Stefano (Louvain U.)
Primordial Black Holes (PBH) from peaks in the curvature power spectrum could constitute today an important fraction of the Dark Matter in the Universe. [...]

Binary Neutron Star Mergers with Missing Electromagnetic Counterparts as Manifestations of Mirror World / Beradze, Revaz (Javakhishvili State U.) ; Gogberashvili, Merab (Javakhishvili State U. ; Tbilisi, Inst. Phys.) ; Sakharov, Alexander S. (Manhattan Coll., Riverdale ; CERN)
We suggest that the major fraction of binary mergers, which might provide gravitational wave signal detectable by LIGO/Virgo, emerged from the hidden mirror sector. Mirror particles do not interact with an ordinary observer except gravitationally, which is the reason why no electromagnetic signals accompanying gravitational waves from mergers with components composed of mirror matter are expected.

Gravitational Wave Astronomy / Domcke, Valerie (speaker) (CERN)
Abstract:The recent discoveries at LIGO/Virgo and pulsar timing arrays have opened a new window to study our universe: gravitational wave astronomy. These observations have shed new light on our understanding of black holes and neutron stars, teaching us about the evolution of stars and galaxies as well as probing fundamental laws of physics.
