Primordial black holes and their gravitational-wave signatures / LISA Cosmology Working Group Collaboration
In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. [...]

Cosmology with the Laser Interferometer Space Antenna / LISA Cosmology Working Group Collaboration
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle physics, from the MeV to the Planck scale. However, the range of potential cosmological applications of gravitational wave observations extends well beyond these two objectives. [...]

Detection of Early-Universe Gravitational Wave Signatures and Fundamental Physics / Caldwell, Robert (Dartmouth Coll.) ; Cui, Yanou (UC, Riverside) ; Guo, Huai-Ke (U.

Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark discovery, potentially providing a significant clue to some of our most basic, big-picture scientific questions about the Universe. In this white paper, we survey the leading early-Universe mechanisms that may produce a detectable signal -- including inflation, phase transitions, topological defects, as well as primordial black holes -- and highlight the connections to fundamental physics.

LIGO Lo(g)Normal MACHO: Primordial Black Holes survive SN lensing constraints / Garcia-Bellido, Juan (Madrid, IFT ; CERN) ; Clesse, Sebastien (Louvain U., CP3 ; Namur U.) ; Fleury, Pierre (Geneva U., Dept. Theor. Phys.)
It has been claimed in Ref.[arXiv:1712.02240] that massive primordial black holes (PBH) cannot constitute all of the dark matter (DM), because their gravitational-lensing imprint on the Hubble diagram of type Ia supernovae (SN) would be incompatible with present observations. In this paper, we critically review those constraints and find several caveats on the analysis. [...]

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. [...]

Constraints from microlensing experiments on clustered primordial black holes / García-Bellido, Juan (Madrid, IFT ; CERN) ; Clesse, Sebastien (Louvain U., CP3 ; RWTH Aachen U. ; Namur U.)
It has recently been proposed that massive primordial black holes (PBH) could constitute all of the dark matter, providing a novel scenario of structure formation, with early reionization and a rapid growth of the massive black holes at the center of galaxies and dark matter halos. The scenario arises from broad peaks in the primordial power spectrum that give both a spatially clustered and an extended mass distribution of PBH. [...]
