A superflare of BP Tau simultaneously caught by EP X-ray and TESS optical observations
Xingyu Zhou, Mingjun Liu, Gregory J. Herczeg +10
Multiwavelength observations of stellar flares trace the activity of different components of the stars' outer atmosphere, providing insight into their interactions. In the present…
Hydrodynamical simulation of wind production from hot accretion flows in tidal disruption events
Mingjun Liu, De-Fu Bu, Xiao-Hong Yang +5
Wind is a key mechanism for supermassive black hole (SMBH) feedback to their host galaxies. In tidal disruption events (TDEs), black holes spend most of their time accreting at hig…
Accretion with two-phase gas supply and its application in black hole X-ray binaries
Yilong Wang, B. F. Liu, Mingjun Liu
Accretion in black hole X-ray binaries is commonly believed to be supplied by the Roche lobe overflow or the stellar wind. The former is thought to form a geometrically thin disc w…
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…
The effectively optically thin accretion flow and its implication in supermassive black holes
Mingjun Liu, B. F. Liu, Yilong Wang +2
Based on a unified description of various accretion flows, we find a long-ignored solution - the effectively optically thin accretion flow, occurring at accretion rates around Eddi…
A generalized solution for advection-dominated accretion flow, standard disc, and slim disc
Mingjun Liu, B. F. Liu, Yilong Wang +2
Aiming at a general description of four basic solutions describing the accretion processes, i.e., the Shakura-Sunyaev thin disc (SSD), the Shapiro-Lightman-Eardley solution (SLE),…
Detection of an Orphan X-ray Flare from a Blazar Candidate EP240709a with Einstein Probe
Mingjun Liu, Yijia Zhang, Yun Wang +49
Blazars are often observed to flare across multiple wavelengths. Orphan flares from blazars have been only detected a few times, providing an opportunity to understand the structur…
Long-term stability of scientific X-ray CMOS detectors
Mingjun Liu, Qinyu Wu, Zhixing Ling +3
In recent years, complementary metal-oxide-semiconductor (CMOS) sensors have been demonstrated to have significant potential in X-ray astronomy, where long-term reliability is cruc…
Einstein Probe discovery of EP240408a: a peculiar X-ray transient with an intermediate timescale
Wenda Zhang, Weimin Yuan, Zhixing Ling +136
We report the discovery of a peculiar X-ray transient, EP240408a, by Einstein Probe (EP) and follow-up studies made with EP, Swift, NICER, GROND, ATCA and other ground-based multi-…
LEIA discovery of the longest-lasting and most energetic stellar X-ray flare ever detected
Xuan Mao, He-Yang Liu, Song Wang +40
The Lobster Eye Imager for Astronomy (LEIA) detected a new X-ray transient on 2022 November 7, identified as a superflare event occurring on a nearby K-type giant star HD 251108. T…
Radiation Effects on Scientific CMOS Detectors for X-ray Astronomy: II. Total Ionizing Dose Irradiation
Mengxi Chen, Zhixing Ling, Mingjun Liu +6
Complementary metal-oxide-semiconductor (CMOS) detectors are a competitive choice for current and upcoming astronomical missions. To understand the performance variations of CMOS d…
Constraining the X-ray radiation origin of 3C 273 in the low state by polarization
Mingjun Liu, Wenda Zhang, Weimin Yuan
3C 273 is one of the nearest high-luminosity quasars. Although classified as a blazar, 3C 273 also has some features in Seyferts, whose X-ray may originate from the corona. Since b…
Radiation effects on scientific CMOS sensors for X-ray astronomy: I. proton irradiation
Mingjun Liu, Zhixing Ling, Qinyu Wu +5
Complementary metal-oxide-semiconductor (CMOS) sensors are a competitive choice for future X-ray astronomy missions. Typically, CMOS sensors on space astronomical telescopes are ex…
