Statistical properties of type-II bursts in Rapid Burster observed with Insight-HXMT

Shi-peng Wang, Long Ji

We report the detection of type-II X-ray bursts in a neutron star low mass X-ray binary MXB 1730-335 (also known as Rapid Burster) observed with Insight- HXMT satellite. We found s…

An extreme particle accelerator powered by pulsar PSR J1849-0001

The LHAASO Collaboration

Pulsar wind nebulae (PWNe) are bubbles of relativistic particles, powered by the rotational energy loss of the central pulsars. The Crab Nebula, powered by the Milky Way's most ene…

The Faintest, Extremely Variable X-ray Tidal Disruption Event from a Supermassive Black Hole Binary?

Mengqiu Huang, Yongquan Xue, Shuo Li +30

Tidal disruption events (TDEs), which occur when stars enter the tidal radii of supermassive black holes (SMBHs) and are subsequently torn apart by their tidal forces, represent in…

Spectral Hardening Reveals Afterglow Emergence in Long-Duration Fast X-ray Transients: A Case Study of GRB 250404A/EP250404a

Yi-Han Iris Yin, Yuan Fang, Bin-Bin Zhang +56

The prompt emission and afterglow phases of gamma-ray bursts (GRBs) have been extensively studied, yet the transition between these two phases remains inadequately characterized du…

Multi-wavelength study for gamma-ray nova V1405 Cas

Zi-wei Ou, Pak-hin Thomas Tam, Hui-hui Wang +2

Novae are found to have GeV to TeV gamma-ray emission, which reveals the shock acceleration from the white dwarfs. Recently, V1405 Cas was reported to radiated suspicious gamma-ray…

Ultrahigh-Energy Gamma-ray Emission Associated with Black Hole-Jet Systems

The LHAASO Collaboration, Zhen Cao, Felix Aharonian +315

Black holes (BH), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass B…

Expansion and Spectral Softening of the Dust Scattering Rings of GRB 221009A

Guoying Zhao, Rong-Feng Shen

Expanding X-ray halo or rings appear when short pulses of X-ray radiation from a background source are scattered by clouds of dust in the Milky Way. We study the X-ray rings of the…

A tera-electronvolt afterglow from a narrow jet in an extremely bright gamma-ray burst 221009A

LHAASO Collaboration

Some gamma-ray bursts (GRBs) have an afterglow in the tera-electronvolt (TeV) band, but the early onset of this afterglow has not been observed. We report observations with the Lar…

The dispersion measure and scattering of FRBs: Contributions from the intergalactic medium, foreground halos, and hosts

Weishan Zhu, Long-Long Feng

We investigate the dispersion measure(DM) and scattering of FRBs by the intergalactic-medium(IGM), foreground and host halos, using cosmological hydrodynamical simulation. We find…
