Insight-HXMT is China’s 1st X-ray astronomy satellite launched in 2017 and still working nominally in orbit. With its broad energy band (1-250 keV) and large effective area (about 400, 1000, 5000 cm^2 in three energy bands), it has been used to make many new discoveries with its observations on accreting X-ray pulsars, such as the highest energy cyclotron absorption features above 100 keV....
After obtaining black hole solutions in the bumblebee gravity theory, we put constraints on theory parameters with Solar system observations, black hole images, and extreme mass ratio inspirals.
If the temperature of the hot thermal plasma in the Early Universe was within a few orders of magnitude of the quantum gravity scale, then the hoop conjecture predicts the formation of microscopic black holes from particle collisions in the plasma. These black holes may evaporate and produce the dark matter relic abundance observed today for a wide variety of dark matter masses. We study the...
We go beyond the state-of-the-art by combining first principal lattice results and effective field theory approaches as Polyakov Loop model to explore the nonperturbative dark deconfinement-confinement phase transition and the generation of gravitational-waves in a dark Yang-Mills theory. We further include fermions with different representations in the dark sector. Employing the...
The delayed GeV−TeV cascade emission from extragalactic TeV−PeV sources are regarded as an ideal probe of the inter-galactic magnetic fields. Recently, LHAASO has detected ~10 TeV emission of the extraordinary powerful GRB 221009A within ~2000 s after the burst. Here we report the detection of a ~400 GeV photon, without accompanying prominent low-energy emission, by Fermi-LAT in the direction...
High-frequency gravitational waves (HFGWs) carry a wealth of information on the early Universe with a tiny comoving Hubble horizon and astronomical objects of small scale but with dense energy. We demonstrate that the nearby planets, such as Earth and Jupiter, can be utilized as a laboratory for detecting the HFGWs. These GWs are then expected to convert to signal photons in the planetary...
