Emery Trott is a Physics PhD candidate at the University of Michigan advised by Dragan Huterer. Emery is interested in tensions in the LCDM model of the Universe, and is currently working on how gravitational waves can inform us about the Hubble constant.
Dark Siren Gravitational Waves and the Hubble Constant
Gravitational waves produced by compact binary mergers are "standard sirens" whose distances can be combined with electromagnetic follow-up surveys to measure the Hubble constant. This powerful new probe will soon meaningfully weigh-in on the 5-sigma Hubble tension, and on possible extensions of Lambda-CDM cosmology. A major complicating factor is that over 95% of these events do not actually have identifiable electromagnetic counterparts, and are therefore considered "dark sirens". This talk will touch on the current state of gravitational wave cosmology and address the methods for extracting reliable information on the Hubble constant from dark sirens.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Office of Indigenous Relations.
