In this talk I will briefly introduce two flagship high energy astrophysics missions: HERD onboard the China space station and eXTP observatory. HERD is a large cosmic-ray experiment developed by a Sino-European consortium onboard China’s Space Station for operation around 2027, with unprecedented acceptance and energy range for direct measurements of cosmic-rays and electrons, as well as a...
The Einstein Probe (EP) is a space mission dedicated to X-ray time-domain astrophysics, and is to be launched in the near future. It carries two instruments. One is a wide-field X-ray telescope (WXT) with a 3600 square-degree FoV and moderate angular resolution of 5arcmin (fwhm) operating in the 0.5-4keV soft X-ray band. The other is a Wolter-I X-ray telescope (FXT) for deep follow-up...
Hot Universe Baryon Surveyor (HUBS) is a proposed X-ray mission that is dedicated to probing hot gas, which is theoretically postulated to permeate the circumgalactic space and the cosmic web, through means of high throughput, high resolution X-ray spectroscopy. On galaxy scales, the hot gas is thought to be a key component of galaxy ecosystems, produced by stellar or black-hole feedback...
The MeV Astrophysical Spectroscopic Surveyor (MASS) is a conceptual Compton telescope using 3D position sensitive cadmium zinc telluride (CZT) detectors. The CZT detector works at room-temperature with a spectral resolution of 0.6% at 0.662 MeV, enabling us to construct a large format Compton telescope to measure astrophysical nuclear emission lines, and address astrophysical problems...
IceCube's discovery of an extragalactic neutrino flux has marked the beginning of a new era for neutrino astronomy, prompting the development of more sensitive next-gen neutrino telescopes to uncover the source of cosmic rays and explore physics beyond the Standard Model on cosmic scales. Amid global efforts to build advanced observatories, a telescope near Earth's equator provides unique...
Gamma-Ray Burst (GRB) prompt polarization has been measured in more than thirty cases. However, as they suffered from large systematical/statistical uncertainties, they showed a wide range distribution of polarization degrees (PDs). The theoretical community has recently paid more attention to the POLAR mission, which reported PDs of 14 GRBs at mostly a level of $\sim$10% and a hint of...
This presentation will provide an overview of the Chinese-French SVOM mission, scheduled for launch in the first half of 2024, which aims to study gamma-ray bursts and other high-energy phenomena. The specific characteristics of the SVOM instruments will be detailed presented and the potential scientific contributions will be discussed.
For Cosmic Ecosystems, mapping the circumgalactic medium (CGM) in emission is one of the important scientific goals for astronomers to either use the modern ground-based telescopes or the future space missions. CGMs are multi-phases, key to understand the galaxy ecosystem and its accretion and feedback. In this talk, I will briefly introduce a few scientific projects in our group for the...
Gravitational wave (GW) detections have ushered in a new era for astronomy, significantly expanding the horizons of gravitational physics and high-energy astrophysics. Numerous GW events originating from compact binary systems have been successfully detected, among which stands out the renowned binary neutron star event, GW170817. This milestone event represents the inaugural joint detection...
