AT2019ijn: a fast-rising, slow-decaying blue optical transient with exceptionally bright radio emission
Hucheng Ding, Xinwen Shu, Luming Sun +9
We report the discovery of a peculiar optical transient, AT2019ijn, occurred in the nuclear region of a dwarf galaxy at z=0.273. It rises rapidly to peak at a luminosity of Mg=-21.…
Fast radio bursts, magnetars and earthquakes: their "family feud"?
Si-Lu Xu, Yong-Kun Zhang, Pei Wang +24
Fast radio bursts (FRBs) are millisecond-duration cosmic transients whose origin remains elusive. Competing models invoke either earthquake-like processes or flare-like mechanisms.…

Hyunwook Ro, Motoki Kino, Kazuhiro Hada +6
We present an in-depth analysis of transverse oscillations in the M87 jet, as identified in our previous study (Ro et al. 2023a), which reported oscillatory patterns with a charact…
Flux Variations of Fast Radio Bursts and Their Persistent Radio Sources: Evidence for a Shared Progenitor
Xinming Li, Chenhui Niu, Jiaheng Zhang +24
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio transients, some of which are associated with compact persistent radio sources (PRSs), hinting at a physical c…
An Archival Optical Counterpart Search for Extragalactic Fast X-Ray Transients Discovered by Einstein Probe
Run-Duo Liang, Wen-Xiong Li, Liang-Duan Liu +50
Extragalactic fast X-ray transients (eFXTs) represent a rapidly growing class of high-energy phenomena, whose physical origins remain poorly understood. With its wide-field, sensit…
Locating the missing large-scale emission in the jet of M87* with short EHT baselines
Boris Georgiev, Paul Tiede, Sebastiano D. von Fellenberg +280
In Very-Long Baseline Interferometric arrays, nearly co-located stations probe the largest scales and typically cannot resolve the observed source. In the absence of large-scale st…
Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations
Saurabh, Hendrik Müller, Sebastiano D. von Fellenberg +282
We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the enhanced uv coverage in the 2021 Event Horizon Telescope (EHT) o…
A Persistently Active Fast Radio Burst source Embedded in an Expanding Supernova Remnant
Chen-Hui Niu, Di Li, Yuan-Pei Yang +21
Fast radio bursts (FRBs) remain one of the most puzzling astrophysical phenomena. While most FRBs are detected only once or sporadically, we present the identification of FRB 20190…
Could the stochastic gravitational wave background from newborn magnetars be detected by the advanced LIGO and Einstein Telescope?
Yu-Long Yan, Quan Cheng, Xiao-Ping Zheng +1
Newborn magnetars are important gravitational wave sources due to their ultra-strong magnetic fields and fast spins, and the entire population in the Universe may significantly con…
Eclipsed X-ray Bursts from Magnetar SGR J1935+2154 and the Fireball Measurements
Sheng-Lun Xie, Aming Chen, Yun-Wei Yu +17
In theory, burst activity of the magnetar can lead to the formation of fireballs trapped by the magnetic field and corotating with the star. However, the smoking-gun observational…
Horizon-scale variability of M87* from 2017--2021 EHT observations
The Event Horizon Telescope Collaboration
We report three epochs of polarized images of M87* at 230\,GHz using data from the Event Horizon Telescope (EHT) taken in 2017, 2018, and 2021. The baseline coverage of the 2021 ob…
Extending the short gamma-ray burst population from sub-threshold triggers in Fermi/GBM and GECAM data and its implications
Ce Cai, Shao-Lin Xiong, Yan-Qiu Zhang +21
Detection of short gamma-ray bursts (SGRBs) is critically important for the research of compact object mergers and multi-messenger astrophysics, but a significant part of SGRBs fal…
The magnetar model's energy crisis for a prolific repeating fast radio burst source
Jun-Shuo Zhang, Tian-Cong Wang, Pei Wang +61
Fast radio bursts (FRBs) are widely considered to originate from magnetars that power the explosion through releasing magnetic energy. Active repeating FRBs have been seen to produ…
