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
Andy D. Goulding, Kris Pardo, Jenny E. Greene +3
Supermassive black hole (SMBH) binaries with masses of ~10^8--10^9 Msun are expected to dominate the contribution to the as-yet undetected gravitational wave background (GWB) signa…
Modified Gravity and Dark Energy models Beyond CDM Testable by LSST
Mustapha Ishak, Tessa Baker, Philip Bull +8
One of the main science goals of the Large Synoptic Survey Telescope (LSST) is to uncover the nature of cosmic acceleration. In the base analysis, possible deviations from the Lamb…
