A compact time-domain reduced order quadrature for gravitational wave inspirals with non-stationary noise
Benjamin Zhang, Kris Pardo, Bence Bécsy
We develop the first time-domain reduced order quadrature for gravitational waves in the early inspiral period, motivated by the need for dataset compression in the presence of gap…
A New Probe of Dark Matter Subhalos: Stellar Aberration with TESS
Matthias Daniel, Xiao Xue, Kris Pardo +1
Small-scale dark matter (DM) structure encodes key information about the particle nature of DM and therefore provides a sensitive test of competing models. Yet, it remains hidden f…
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…
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…
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…
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…
Effective Field Theory for Dark Matter Absorption on Single Phonons
Andrea Mitridate, Kris Pardo, Tanner Trickle +1
Single phonon excitations, with energies in the range, are a powerful probe of light dark matter (DM). Utilizing effective field theory, we derive a framework…
Contrast Loss from Astrophysical Backgrounds in Space-Based Matter-Wave Interferometers
Yufeng Du, Clara Murgui, Kris Pardo +2
Atom and matter interferometers are precise quantum sensing experiments that can probe differential forces along separated spacetime paths. Various atom and matter interferometer e…
Gravitational Wave Detection with Relative Astrometry using Roman's Galactic Bulge Time Domain Survey
Kris Pardo, Tzu-Ching Chang, Olivier Doré +1
Gravitational waves (GWs) are a new avenue of observing our Universe. So far, we have seen them in the ~10-100 Hz range, and there are hints that we might soon detect them in the n…
Atom Interferometer Tests of Dark Matter
Yufeng Du, Clara Murgui, Kris Pardo +2
Direct detection experiments for dark matter are increasingly ruling out large parameter spaces. However, light dark matter models with particle masses GeV are still largely un…
Constraining the Stochastic Gravitational Wave Background with Photometric Surveys
Yijun Wang, Kris Pardo, Tzu-Ching Chang +1
The detection of the Stochastic Gravitational Wave Background (SGWB) is essential for understanding black hole populations, especially for supermassive black hole binaries. The rec…
Detecting dark matter subhalos with the Nancy Grace Roman Space Telescope
Kris Pardo, Olivier Doré
The dark matter subhalo mass function is a promising way of distinguishing between dark matter models. While cold dark matter predicts halos down to Earth-sized masses, other dark…
A quasar-based supermassive black hole binary population model: implications for the gravitational-wave background
J. Andrew Casey-Clyde, Chiara M. F. Mingarelli, Jenny E. Greene +3
The nanohertz gravitational wave background (GWB) is believed to be dominated by GW emission from supermassive black hole binaries (SMBHBs). Observations of several dual active gal…
Gravitational Wave Detection with Photometric Surveys
Yijun Wang, Kris Pardo, Tzu-Ching Chang +1
Gravitational wave (GW) detections have enriched our understanding of the universe. To date, all single-source GW events were found by interferometer-type detectors. We study a det…
What is the price of abandoning dark matter? Cosmological constraints on alternative gravity theories
Kris Pardo, David N. Spergel
Any successful alternative gravity theory that obviates the need for dark matter must fit our cosmological observations. Measurements of microwave background polarization trace the…
Testing self-interacting dark matter with galaxy warps
Kris Pardo, Harry Desmond, Pedro G. Ferreira
Self-interacting dark matter (SIDM) is an able alternative to collisionless dark matter. If dark matter does have self-interactions, we would expect this to cause a separation betw…
Discovery of a close-separation binary quasar at the heart of a z~0.2 merging galaxy and its implications for low-frequency gravitational waves
