Sensitivity of Weak Lensing Surveys to Gravitational Waves from Inspiraling Supermassive Black Hole Binaries
Tal Adi, Kris Pardo, Olivier Doré
We explore the sensitivity of weak lensing surveys to gravitational waves (GWs) emitted by inspiraling supermassive black hole binaries (SMBHBs) in the nanohertz to microhertz freq…
Archival Multiband Gravitational-Wave Signals from Massive Black Hole Binary Mergers
Alexander W. Criswell, Stephen R. Taylor, Kris Pardo +4
While massive black hole binaries (MBHBs) merge at gravitational-wave frequencies above the pulsar timing array (PTA) sensitivity band, we show that they leave orphaned low-frequen…
The Atacama Cosmology Telescope: A Test of the Gravitational Force Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect
Patricio A. Gallardo, Kris Pardo, Oliver H. E. Philcox +38
The mean pairwise velocity of massive halos reflects the gravitational force law on cosmic scales. We combine cosmic microwave background intensity maps from the Atacama Cosmology…
Forecasted Detection Limits on the (Dark) Matter Density in Supermassive Black Hole Binaries for LISA
Matthias Daniel, Kris Pardo, Laura Sagunski
Supermassive black hole binaries (SMBHBs) are among the most powerful known sources of gravitational waves (GWs). Accordingly, these systems could dominate GW emission in the micro…
Constraints on the dark matter-baryon interaction cross section from galaxy cluster thermodynamics
Eleanor Stuart, Kris Pardo
Dark matter (DM) models with a non-zero DM-baryon interaction cross section imply energy transfer between DM and baryons. We present a new method of constraining the DM-baryon inte…
A Fast Bayesian Method for Coherent Gravitational Wave Searches with Relative Astrometry
Benjamin Zhang, Kris Pardo, Yijun Wang +3
Using relative stellar astrometry for the detection of coherent gravitational wave sources is a promising method for the microhertz range, where no dedicated detectors currently ex…
