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…
Unraveling the mysteries of supernovae with SKA+VLBI
Tao An, Zhengwei Liu, Ailing Wang +6
Supernovae (SNe) drive cosmic chemical enrichment and shape galactic feedback, yet the link between progenitors and explosion outcomes remains poorly constrained because the earlie…
Transforming X-ray Binary Astrophysics with SKA+VLBI
Tao An, Ailing Wang, James C. A. Miller-Jones +6
X-ray binaries (XRBs) are unique laboratories where accretion, jets, strong gravity and magnetic fields can be probed on humanly tractable timescales. The phased SKA-Mid operating…
Multiwavelength Analysis of the Einstein Probe X-ray Transient EP240305a
Ruican Ma, Ye Li, Lian Tao +32
We report multiwavelength observations of EP240305a, an uncatalogued X-ray transient detected by the Einstein Probe on March 5, 2024. The source exhibits distinct characteristics a…
Deep VLBI constraints on compact radio cores in four ultraluminous X-ray sources
Ailing Wang, Hua Feng, Tao An +7
We present high-sensitivity Very Long Baseline Interferometry (VLBI) observations of four ultraluminous X-ray sources (ULXs): Holmberg II X-1, IC 342 X-1, NGC 6946 X-1, and NGC 925…
A Delayed Radio Flare Traces Kinetic Energy Injection in the SMBHB Candidate SDSS~J143016.05+230344.4
Tao An, Ailing Wang, Yingkang Zhang +12
SDSS~J143016.05+230344.4 () has been proposed as a candidate pre-coalescence supermassive black hole binary and shows remarkable multiwavelength variability. Its radio e…
High-redshift quasars at -- III. Parsec-scale jet properties from VLBI observations
Shaoguang Guo, Tao An, Yuanqi Liu +5
High redshift active galactic nuclei (AGN) provide key insights into early supermassive black hole growth and cosmic evolution. This study investigates the parsec-scale properties…
High-Frequency and High-Resolution VLBI Observations of GHz Peaked Spectrum Objects
Xiaopeng Cheng, Tao An, Ailing Wang +1
Observational studies of GHz peaked spectrum (GPS) sources contribute to the understanding of the radiative properties and interstellar environment of host galaxies. We present the…
Interactions between the jet and disk wind in a nearby radio intermediate quasar III Zw 2
Ailing Wang, Tao An, Shaoguang Guo +13
Disk winds and jets are ubiquitous in active galactic nuclei (AGN), and how these two components interact remains an open question. We study the radio properties of a radio-interme…
Is the X-ray bright z = 5.5 quasar SRGE J170245.3+130104 a blazar?
Tao An, Ailing Wang, Yuanqi Liu +11
Jets may have contributed to promoting the growth of seed black holes in the early Universe, and thus observations of radio-loud high-redshift quasars are crucial to understanding…
J2102+6015: a young radio source at z = 4.575
Yingkang Zhang, Tao An, Sándor Frey +7
Jets of high-redshift active galactic nuclei (AGNs) can be used to directly probe the activity of the black holes in the early Universe. Radio sources with jets misaligned with res…
High-resolution VLBI observations of and modelling the radio emission from the TDE AT2019dsg
Prashanth Mohan, Tao An, Yingkang Zhang +3
A tidal disruption event (TDE) involves the shredding of a star in the proximity of a supermassive black hole (SMBH). The nearby (230 Mpc) relatively radio-quiet, thermal…
Parsec-scale Properties of eight Fanaroff-Riley Type 0 Radio Galaxies
Xiaopeng Cheng, Tao An, Bong Won Sohn +2
We report the high-resolution radio observations of eight Fanaroff-Riley type 0 radio galaxies (FR 0s), selected from the published FR 0 sample. These observations were carried out…
