Dark Photon Dark Matter and Low-Frequency Gravitational Wave Detection with Gaia-like Astrometry
Haipeng An, Tingyu Li, Jing Shu +3
Astrometric surveys offer us a method to search for elusive cosmic signatures, such as ultralight dark photon dark matter and gravitational waves, by observing the deflection to th…
Black Holes as Fermion Factories
Yifan Chen, Xiao Xue, Vitor Cardoso
Ultralight bosons near rotating black holes can undergo significant growth through superradiant energy extraction, potentially reaching field values close to the Planck scale and t…
Adiabatically compressed wave dark matter halo and intermediate-mass ratio inspirals
Hyungjin Kim, Alessandro Lenoci, Isak Stomberg +1
The adiabatic growth of a central massive black hole could compress the surrounding dark matter halo, leading to a steeper profile of the dark matter halo. This phenomenon is calle…
Photon Ring Astrometry for Superradiant Clouds
Yifan Chen, Xiao Xue, Richard Brito +1
Gravitational atoms produced from the superradiant extraction of rotational energy of spinning black holes can reach energy densities significantly higher than that of dark matter,…
Birefringence Tomography for Axion Cloud
Yifan Chen, Chunlong Li, Yosuke Mizuno +5
An axion cloud surrounding a supermassive black hole can be naturally produced through the superradiance process. Its existence can be examined by the axion induced birefringence e…
High-precision search for dark photon dark matter with the Parkes Pulsar Timing Array
Xiao Xue, Zi-Qing Xia, Xingjiang Zhu +20
The nature of dark matter remains obscure in spite of decades of experimental efforts. The mass of dark matter candidates can span a wide range, and its coupling with the Standard…
Dissecting axion and dark photon with a network of vector sensors
Yifan Chen, Min Jiang, Jing Shu +2
We develop formalisms for a network of vector sensors, sensitive to certain spatial components of the signals, to identify the properties of a light axion or a dark photon backgrou…
Earth Shielding and Daily Modulation from Electrophilic Boosted Dark Particles
Yifan Chen, Bartosz Fornal, Pearl Sandick +4
Boosted dark particles of astrophysical origin can lead to nonstandard nuclear or electron recoil signals in direct detection experiments. %It has been shown that this interpretati…
Constraining cosmological phase transitions with the Parkes Pulsar Timing Array
Xiao Xue, Ligong Bian, Jing Shu +15
A cosmological first-order phase transition is expected to produce a stochastic gravitational wave background. If the phase transition temperature is on the MeV scale, the power sp…
Stringent axion constraints with Event Horizon Telescope polarimetric measurements of M87
Yifan Chen, Yuxin Liu, Ru-Sen Lu +5
The hitherto unprecedented angular resolution of the Event Horizon Telescope (EHT) has created exciting opportunities in the search for new physics. Recently, the linear polarizati…
LIGO as a probe of Dark Sectors
Fei Huang, Veronica Sanz, Jing Shu +1
We show how current LIGO data is able to probe interesting theories beyond the Standard Model, particularly Dark Sectors where a Dark Higgs triggers symmetry breaking via a first-o…
UV Completed Composite Higgs model with heavy composite partners
Zi-Yu Dong, Cong-Sen Guan, Teng Ma +2
We study electroweak symmetry breaking in minimal composite Higgs models with purely fermionic UV completions based on a confining Hypercolor gauge group and find tha…
Sun Heated MeV-scale Dark Matter and the XENON1T Electron Recoil Excess
Yifan Chen, Ming-Yang Cui, Jing Shu +3
The XENON1T collaboration reported an excess of the low-energy electron recoil events between 1 and 7 keV. We explore the possibility to explain such an anomaly by the MeV-scale da…
Probing Axions with Event Horizon Telescope Polarimetric Measurements
Yifan Chen, Jing Shu, Xiao Xue +2
With high spatial resolution, polarimetric imaging of a supermassive black hole, like M87 or Sgr A, by the Event Horizon Telescope can be used to probe the existenc…
Detecting dark photon dark matter with Gaia-like astrometry observations
Huai-Ke Guo, Yingqi Ma, Jing Shu +3
A class of dark photon dark matter models with ultralight masses would lead to oscillation of a test body through a coupling with baryons or charge. This periodical oscillati…
