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…

Gravitational lensing rarely produces high-mass outliers to the compact binary population

Amanda M. Farah, Jose María Ezquiaga, Maya Fishbach +1

All gravitational-wave signals are inevitably gravitationally lensed by intervening matter as they propagate through the Universe. When a gravitational-wave signal is magnified, it…

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…

Kilonova constraints for the LIGO/Virgo/KAGRA neutron star merger candidate S250206dm: GW-MMADS observations

Lei Hu, Tomás Cabrera, Antonella Palmese +35

Gravitational wave (GW) neutron star mergers with an associated electromagnetic counterpart constitute powerful probes of binary evolution, the production sites of heavy elements,…

A neural network emulator of the Advanced LIGO and Advanced Virgo selection function

Thomas A. Callister, Reed Essick, Daniel E. Holz

Characterization of search selection effects comprises a core element of gravitational-wave data analysis. Knowledge of selection effects is needed to predict observational prospec…

Gravitational-wave dark siren cosmology systematics from galaxy weighting

Alexandra G. Hanselman, Aditya Vijaykumar, Maya Fishbach +1

The detection of GW170817 and the measurement of its redshift from the associated electromagnetic counterpart provided the first gravitational wave determination of the Hubble cons…
