Abnormal Nitrogen Abundance in the X-ray Spectrum of Quasi-periodically Erupting Source AT2019wzc
Tao Wu, Xinwen Shu, Luming Sun +3
Quasi-periodic eruptions (QPEs) are rapid, recurring soft X-ray bursts, whose nature is still in dispute. A compelling case of QPEs has emerged in the slowly evolving optical trans…
Exploring Tidal Disruption Events with SKA and VLBI: Unveiling the Mystery of Black Hole Feeding and Outflows
Xinwen Shu, Guobin Mou, Tao An +8
Tidal disruption events (TDEs) probe the birth and evolution of black hole accretion flows and jets on human timescales. Radio emission traces shocks and outflows from thermal TDEs…
Outflow-cloud interaction as the possible origin of the peculiar radio emission in the tidal disruption event AT2018cqh
Lei Yang, Xinwen Shu, Guobin Mou +9
AT2018cqh is a unique optical tidal disruption event (TDE) discovered in a dwarf galaxy exhibiting delayed X-ray and radio flares. We present the results from high-resolution VLBA…
EP241021a: a months-duration X-ray transient with luminous optical and radio emission
Shu Xinwen, Yang Lei, Yang Haonan +82
We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
An 85-s X-ray quasi-periodicity after a stellar tidal disruption by a candidate intermediate-mass black hole
Wenjie Zhang, Xinwen Shu, Luming Sun +4
It is still in dispute the existence of intermediate-mass black holes (IMBHs) with a mass of ~10^3-10^5 solar masses (Msun), which are the missing link between stellar-mass black h…
Discovery of a years-delayed radio flare from an unusually slow-evolved tidal disruption event
Zhumao Zhang, Xinwen Shu, Lei Yang +19
SDSS J1115+0544 is a unique low-ionization nuclear emission-line region (LINER) galaxy with energetic ultraviolet (UV), optical and mid-infrared outbursts occurring in its nucleus.…
Recurring tidal disruption events a decade apart in IRAS F01004-2237
Luming Sun, Ning Jiang, Liming Dou +16
We report the discovery of a second optical flare that occurred in September 2021 in IRAS F01004-2237, where the first flare occurred in 2010 has been reported, and present a detai…
Delayed and fast rising radio flares from an optical and X-ray detected tidal disruption event in the center of a dwarf galaxy
Fabao Zhang, Xinwen Shu, Lei Yang +7
AT2018cqh is a unique tidal disruption event (TDE) candidate discovered in a dwarf galaxy. Both the light curve fitting and galaxy scaling relationships suggest a central black hol…
Broadband multi-wavelength study of LHAASO detected AGN
Ze-Rui Wang, Rui Xue, Dingrong Xiong +4
Recently, the Large High Altitude Air Shower Observatory (LHAASO) collaboration presented the first catalog of -ray sources using 508 days of LHAASO data, from March 2021 to Sep…
A possible 250-second X-ray quasi-periodicity in the fast blue optical transient AT2018cow
Wenjie Zhang, Xinwen Shu, Jin-Hong Chen +11
The fast blue optical transients (FBOTs) are a new population of extragalactic transients of unclear physical origin. A variety of mechanisms have been proposed including failed su…
A Mid-infrared Study of Superluminous Supernovae
Luming Sun, Lin Xiao, Ge Li
We present the mid-infrared (MIR) light curves (LC) of 10 superluminous supernovae (SLSNe) at based on WISE data at 3.4 and 4.6 m. Three of them, including PS15br, SN 2…
X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary
Xinwen Shu, Wenjie Zhang, Shuo Li +8
Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches…
Years Delayed X-ray Afterglows of TDEs Originated from Wind-Torus Interactions
Guobin Mou, Liming Dou, Ning Jiang +8
Tidal disruption events (TDEs) occurred in active galactic nuclei (AGNs) are a special class of sources with outstanding scientific significance. TDEs can generate ultrafast winds,…
Awakening of two -ray high redshift flat-spectrum radio quasars in the southern hemisphere
Shang Li, Lu-Ming Sun, Neng-Hui Liao +1
High-redshift blazars are valuable tools to study the early Universe. So far only a handful of -ray blazars have been found at redshifts above 3. -ray signals are detected in…
