Testing Einstein's Equivalence Principle with Fast Radio Bursts

Jun-Jie Wei, He Gao, Xue-Feng Wu +1

The accuracy of Einstein's Equivalence Principle (EEP) can be tested with the observed time delays between correlated particles or photons that are emitted from astronomical source…

X-ray softening during the 2008 outburst of XTE J1810-189

Shan-Shan Weng, Shuang-Nan Zhang, Shu-Xu Yi +2

XTE J1810-189 underwent an outburst in 2008, and was observed over d by RXTE. Performing a time-resolved spectral analysis on the photospheric radius expansion burst det…

Constraints on binary neutron star merger product from short GRB observations

He Gao, Bing Zhang, Hou-Jun Lü

Binary neutron star mergers are strong gravitational wave (GW) sources and the leading candidates to interpret short duration gamma-ray bursts (SGRBs). Under the assumptions that S…

Capturing the electromagnetic counterparts of binary neutron star mergers through low latency gravitational wave triggers

Q. Chu, E. J. Howell, A. Rowlinson +5

We investigate the prospects for joint low-latency gravitational wave (GW) detection and prompt electromagnetic (EM) follow-up observations of coalescing binary neutron stars (BNSs…

Cosmic Transients Test Einstein's Equivalence Principle out to GeV Energies

He Gao, Xue-Feng Wu, Peter Mészáros

The Einstein Equivalence Principle (EEP) can be probed with astrophysical sources emitting simultaneously different types of neutral particles, or particles with varying energies,…

Investigation of the emission radii of kHz QPOs for the accreting millisecond X-Ray pulsars, Atoll and Z sources

D. H. Wang, L. Chen, C. M. Zhang +3

We infer the emission positions of twin kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low mass X-ray binaries (NS-LMXBs) based on the Alfven wave oscillation mod…

The Silicon and Calcium High-Velocity Features in Type Ia Supernovae from Early to Maximum Phases

Xulin Zhao, Xiaofeng Wang, Keiichi Maeda +7

The high-velocity features (HVFs) in optical spectra of type Ia supernovae (SNe Ia) are examined with a large sample including very early-time spectra (e.g., t < -7 days). Multiple…

Strongly lensed gravitational waves from intrinsically faint double compact binaries - prediction for the Einstein Telescope

Xuheng Ding, Marek Biesiada, Zong-Hong Zhu

With a fantastic sensitivity improving significantly over the advanced GW detectors, Einstein Telescope (ET) will be able to observe hundreds of thousand inspiralling double compac…

Plasma-wave generation in a dynamic spacetime

Huan Yang, Fan Zhang

We propose a new electromagnetic-emission mechanism in magnetized, force-free plasma, which is driven by the evolution of the underlying dynamic spacetime. In particular, the emiss…

Physical Dust Models for the Extinction toward Supernova 2014J in M82

Jian Gao, B. W. Jiang, Aigen Li +2

Type Ia supernovae (SNe Ia) are powerful cosmological "standardizable candles" and the most precise distance indicators. However, a limiting factor in their use for precision cosmo…

The NuSTAR View of a QPO Evolution of GRS 1915+105

Liang Zhang, Li Chen, Jinlu Qu +1

We report a timing analysis of the black hole binary GRS 1915+105 with the NuSTAR observatory. A strong type-C QPO below 2 Hz appears in the power density spectrum during the whole…

Dark matter searches in the gamma-ray extragalactic background via cross-correlations with galaxy catalogues

Alessandro Cuoco, Jun-Qing Xia, Marco Regis +3

We compare the measured angular cross-correlation between the Fermi-LAT gamma-ray sky and catalogues of extra-galactic objects with the expected signal induced by weakly interactin…

Magnetosphere of a Kerr black hole immersed in magnetized plasma and its perturbative mode structure

Huan Yang, Fan Zhang, Luis Lehner

This work studies jet-like electromagnetic configurations surrounding a slowly-spinning black-hole immersed in a uniformly magnetized force-free plasma. In the first part of this w…
