Decoding Dark Matter Substructure without Supervision
Stephon Alexander, Sergei Gleyzer, Hanna Parul +4
The identity of dark matter remains one of the most pressing questions in physics today. While many promising dark matter candidates have been put forth over the last half-century,…
Deep learning the astrometric signature of dark matter substructure
Kyriakos Vattis, Michael W. Toomey, Savvas M. Koushiappas
We study the application of machine learning techniques for the detection of the astrometric signature of dark matter substructure. In this proof of principle a population of dark…
Constraining Early Dark Energy with Large-Scale Structure
Mikhail M. Ivanov, Evan McDonough, J. Colin Hill +4
An axion-like field comprising of the energy density of the universe near matter-radiation equality is a candidate to resolve the Hubble tension; this is the "early dar…
Gamma-ray counterparts of 2WHSP high-synchrotron-peaked BL Lac objects as possible signatures of ultra-high-energy cosmic-ray emission
Michael W. Toomey, Foteini Oikonomou, Kohta Murase
We present a search for high-energy -ray emission from 566 Active Galactic Nuclei at redshift , from the 2WHSP catalog of high-synchrotron peaked BL Lac objects with ei…
Early Dark Energy Does Not Restore Cosmological Concordance
J. Colin Hill, Evan McDonough, Michael W. Toomey +1
Current cosmological data exhibit a tension between inferences of the Hubble constant, , derived from early and late-universe measurements. One proposed solution is to introdu…
