Extreme Values of Black Hole to Stellar Mass Ratio for High-Redshift Galaxies
Cameron Heather, Teeraparb Chantavat, Siri Chongchitnan +1
With recent data from the \emph{James Webb Space Telescope} (JWST), it is possible to calculate the mass of the supermassive black holes at the center of galaxies, and the stellar…
Signals of Bursts from the Very Early Universe
Leo Stodolsky, J. Silk
We consider possible observable signals from explosive events in the very early universe, ``bursts". These could be expected in connection with massive black hole or ``baby univers…
Fermi-LAT Galactic Center Excess morphology of dark matter in simulations of the Milky Way galaxy
Moorits Mihkel Muru, Joseph Silk, Noam I. Libeskind +2
The strongest experimental evidence for dark matter is the Galactic Center gamma-ray excess observed by the Fermi telescope and even predicted prior to discovery as a potential dar…
Positron Signal from the Early Universe
L. Stodolsky, J. Silk
Bursts from the very early universe may lead to a detectable signal via the production of positrons, whose annihilation gives an observable X-ray signal. Using the absorption param…
Multi-messenger detection of black hole binaries in dark matter spikes
Fani Dosopoulou, Joseph Silk
We investigate the inspiral of a high mass-ratio black hole binary located in the nucleus of a galaxy, where the primary central black hole is surrounded by a dense dark matter spi…
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…
Anomalous Ionization in the Central Molecular Zone by sub-GeV Dark Matter
Pedro De la Torre Luque, Shyam Balaji, Joseph Silk
We demonstrate that the anomalous ionization rate observed in the Central Molecular Zone can be attributed to MeV dark matter annihilations into pairs for galactic dark ma…
New 511 keV line data provides strongest sub-GeV dark matter constraints
Pedro De la Torre Luque, Shyam Balaji, Joseph Silk
We explore the ~keV emission associated to sub-GeV dark matter (DM) particles that can produce electron-positron pairs and form positronium after thermalizing. We use …
Limits on Primordial Black Holes from M87
J. Silk, L. Stodolsky
Primordial black holes in the solar mass range are a possibly significant component of dark matter. We show how an argument relating the deflection of light by such black holes in…
