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…
Population statistics of nanohertz gravitational wave sources
Jiming Yu, Zhen Pan, Xiao Xue +1
The recent detection of a nanohertz gravitational wave (GW) background by pulsar timing arrays (PTA) has sparked extensive discussions regarding its origin-whether it arises from a…
Probing Fundamental Constant Oscillation in the Galactic Center with S-Star Spectroscopy
Zhaoyu Bai, Vitor Cardoso, Yifan Chen +4
Astrophysical spectroscopy provides a powerful probe of spacetime variations of fundamental constants, as atomic and ionic emission and absorption lines depend sensitively on the f…
Inference on inner galaxy structure via gravitational waves from supermassive binaries
Yifan Chen, Matthias Daniel, Daniel J. D'Orazio +107
The detection of a stochastic gravitational wave background by pulsar-timing arrays indicates the presence of a population of supermassive black hole binaries. Although the observe…
Identifying the Quadrupolar Nature of Gravitational Wave Background through Space-based Missions
Yifan Chen, Yuxiang Liu, Jing Shu +3
The stochastic gravitational wave background (SGWB) consists of an incoherent collection of waves from both astrophysical and cosmological sources. To distinguish the SGWB from noi…
Non-Gaussian Statistics of Nanohertz Stochastic Gravitational Waves
Xiao Xue, Zhen Pan, Liang Dai
Recent detection of nHz stochastic gravitational wave background (SGWB) by multiple pulsar timing arrays (PTAs) has stimulated intensive discussions about its physical origin. In p…
Fundamental Physics Opportunities with the Next-Generation Event Horizon Telescope
Dimitry Ayzenberg, Lindy Blackburn, Richard Brito +45
The Event Horizon Telescope (EHT) Collaboration recently published the first images of the supermassive black holes in the cores of the Messier 87 and Milky Way galaxies. These obs…
Dissecting the Stochastic Gravitational Wave Background with Astrometry
Mesut Çalışkan, Yifan Chen, Liang Dai +3
Astrometry, the precise measurement of star motions, offers an alternative avenue to investigate low-frequency gravitational waves through the spatial deflection of photons, comple…
