Cosmological Evidence for Dark Axion-Dark Baryon Interactions from Apparent Phantom Crossing
Justin Khoury, Meng-Xiang Lin, Mark Trodden
Interactions between dark matter and dark energy can lead to an apparent phantom-crossing behavior that mimics the expansion history preferred by the latest cosmological observatio…
Cosmological Impact of Redshift-Dependent Type Ia Supernovae Calibration
Seyed Hamidreza Mirpoorian, Meng-Xiang Lin, Levon Pogosian
Type Ia supernovae (SNIa) play a central role in constraining the late-time expansion history of the Universe and are directly implicated in current cosmological tensions. Motivate…
First astrometric constraints on parity-violation in the gravitational wave background
Santiago Jaraba, Sachiko Kuroyanagi, Qiuyue Liang +2
Astrometry, the precise measurement of stellar positions and velocities, offers a promising approach to probing the low-frequency stochastic gravitational wave background (SGWB). N…
Apparent and a Lower from Dark Axion and Dark Baryons Interactions
Justin Khoury, Meng-Xiang Lin, Mark Trodden
We show that a simple coupling between dark energy and dark matter can simultaneously address two distinct hints at new physics coming from cosmological observations. The first is…
Testing Gravity with Realistic Gravitational Waveforms in Pulsar Timing Arrays
Wayne Hu, Qiuyue Liang, Meng-Xiang Lin +1
We consider the effects of relaxing the assumption that gravitational waves composing the stochastic gravitational wave background (SGWB) are uncorrelated between frequencies in an…
Probing Parity Violation in the Stochastic Gravitational Wave Background with Astrometry
Qiuyue Liang, Meng-Xiang Lin, Mark Trodden +1
Astrometry holds the potential for testing fundamental physics through the effects of the Stochastic Gravitational Wave Background (SGWB) in the nHz frequency band on…
