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…

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…

Time Variation of Fine-Structure Constant Constrained by [O III] Emission-Lines at 1.1<z<3.7

Ge Li, Luming Sun, Xiangjun Chen +1

[O III]4960,5008 doublet are often the strongest narrow emission lines in starburst galaxies and quasi-stellar objects (QSOs), and thus are a promising probe to possible variat…

SDSS J211852.96-073227.5: a new γ-ray flaring narrow-line Seyfert 1 galaxy

Hui Yang, Weimin Yuan, Su Yao +6

We report on the identification of a new γ-ray-emitting narrow-line Seyfert 1 (NLS1) galaxy, SDSS J211852.96-073227.5 (hereinafter J2118-0732). The galaxy, at a redshift of 0.26, i…

A Uniformly Selected Sample of Low-mass Black Holes in Seyfert 1 Galaxies

Xiao-Bo Dong, Luis C. Ho, Weimin Yuan +4

We have conducted a systematic search of low-mass black holes (BHs) in active galactic nuclei (AGNs) with broad Halpha emission lines, aiming at building a homogeneous sample that…
