When the stars don't align: Investigating inconsistencies in binary black hole formation across population synthesis codes
Alexandra G. Guerrero, Michael Zevin, Duncan B. Maclean +4
Binary population synthesis (BPS) codes are valuable tools for investigating the end-to-end lives of binary stars as well as a myriad of observed astrophysical phenomena. Many ``ra…
LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…
Twin Peaks: Resolving Features in the Binary Black Hole Mass Function with COSMIC-METISSE
Duncan B. Maclean, Poojan Agrawal, Katelyn Breivik +4
Gravitational waves from inspiraling binary black holes (BBHs) provide insights into the lives and deaths of massive stars. Population synthesis allows us to model these binaries t…
A simple model for extracting astrophysics from black hole images
Alexandra G. Guerrero, Daniel E. Holz
The Event Horizon Telescope (EHT) is providing unprecedented high-resolution images of supermassive black holes. These images are fundamentally related to properties of the luminou…
How Low Can You Go: Constraining the Effects of Catalog Incompleteness on Dark Siren Cosmology
Madison VanWyngarden, Maya Fishbach, Aditya Vijaykumar +2
Gravitational waves (GWs) serve as standard sirens by directly encoding the luminosity distance to their source. When the host galaxy redshift is known, for example, through observ…
