LHAASO-WCDA observed a 5 days TeV-delayed flaring event in blazar 1ES 1959+650

Zhen Cao, F. Aharonian, Y. X. Bai +339

We report a day-scale hard lag between GeV and TeV -ray emission from the HBL 1ES~1959+650 in early 2024. Since the LHAASO-WCDA real-time monitoring system began operation in la…

Anisotropic Particle Transport from a Pulsar Wind Nebula Revealed by Einstein Probe and LHAASO

Zhen Cao, F. Aharonian, Y. X. Bai +339

Pulsar wind nebulae (PWNe) are major cosmic ray accelerators, yet the mechanisms transporting high-energy particles into the interstellar medium remain elusive. Building on the LHA…

X-rays breaking out of pre-explosion ejecta mark a supernova's first light

Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130

Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…

A Complete X-ray View of Supernova Remnant W28 with Einstein Probe: Spatial Distribution of Parameters and Origin of the Thermal-Composite Morphology

Yi-Heng Chi, Ping Zhou, Yang Chen +6

It has been an unsolved question what leads a supernova remnant (SNR) to a thermal composite rather than a typical shell-like morphology, and what causes recombining plasma inside…

Minutes-long soft X-ray prompt emission from a compact object merger

An Li, Chen-Wei Wang, Niccolò Passaleva +75

Compact object mergers are multi-messenger sources and known progenitors of some gamma-ray bursts, bright flashes of high-energy radiation powered by a central engine, either an ac…

A fast powerful X-ray transient from possible tidal disruption of a white dwarf

Dongyue Li, Wenda Zhang, Jun Yang +97

Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…

Multiwavelength Observations of the Apparently Non-repeating FRB 20250316A

Ye Li, Hui Sun, Lei Qian +72

The physical origin of fast radio bursts (FRBs) remains uncertain. Although multiwavelength observations have been widely conducted, only Galactic FRB~20200428D is associated with…

The soft X-ray transient EP241021a: A cosmic explosion with a complex off-axis jet and cocoon from a massive progenitor

Giulia Gianfagna, Luigi Piro, Gabriele Bruni +22

X-ray flashes (XRFs) are fast X-ray transients thought to be softer analogs of gamma-ray bursts (GRBs). With its soft X-ray sensitivity, the Einstein Probe (EP) provides a unique o…

EP240801a/XRF 240801B: An X-ray Flash Detected by the Einstein Probe and Implications of its Multiband Afterglow

Shuai-Qing Jiang, Dong Xu, Agnes P. C. van Hoof +89

We present multiband observations and analysis of EP240801a, a low-energy, extremely soft gamma-ray burst (GRB) discovered on August 1, 2024 by the Einstein Probe (EP) satellite, w…

New Timing Results of MSPs from NICER Observations

Shijie Zheng, Dawei Han, Heng Xu +10

Millisecond pulsars (MSPs) are known for their long-term stability. Using six years of observations from the Neutron Star Interior Composition Explorer (NICER), we have conducted a…
