GUEST: Gravitational Universe Exploration with Satellite Tracking. A passive satellite laser-ranging mission for the dark gravitational Universe
Diego Blas, Aurélien Hees, F. Javier Atapuerca +78
GUEST is a space mission concept whose central objective is the detection of gravitational waves (GWs) in the microhertz band -- a physics-rich frequency window that no other prese…
Constraints on Dark Matter Models from Supermassive Black Hole Evolution
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
A semi-analytical model for the evolution of galaxies and supermassive black holes (SMBHs) within the CDM paradigm has been shown to yield stellar mass-BH mass relations that r…
Starlight from JWST: Implications for star formation and dark matter models
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
We confront the star formation rate in different dark matter (DM) models with UV luminosity data from JWST up to and legacy data from HST. We find that a transition fro…
Supermassive black holes from inflation constrained by dark matter substructure
Shin'ichiro Ando, Shyam Balaji, Malcolm Fairbairn +2
Recent James Webb Space Telescope observations of high-redshift massive galaxy candidates have initiated renewed interest in the important mystery around the formation and evolutio…
511 keV Galactic Photons from a Dark Matter Spike
Pedro De la Torre Luque, Shyam Balaji, Malcolm Fairbairn +2
We propose that a dark matter (DM) spike around the Galactic Center's (GC) supermassive black hole, Sgr A*, could account for most of the bulge's measured 511 keV line intensity wh…
Magnetogenesis with gravitational waves and primordial black hole dark matter
Shyam Balaji, Malcolm Fairbairn, Maria Olalla Olea-Romacho
Strongly supercooled first order phase transitions (FOPTs) can produce primordial black hole (PBH) dark matter (DM) along with observable gravitational waves (GWs) from bubble coll…
