Autor: Y. Qin, R.-C. Hu, G. Meynet, Y. Z. Wang, J.-P. Zhu, H. F. Song, X. W. Shu, S. C. Wu

Publikováno v: Astronomy and Astrophysics

To date, various formation channels of merging events have been heavily explored with the detection of nearly 100 double black hole (BH) merger events reported by the LIGO-Virgo-KAGRA (LVK) Collaboration. We here systematically investigate an alterna

CSS J102913+404220 is a peculiar narrow line Seyfert 1 galaxy with an energetic nuclear optical outburst. We present a detailed analysis of its multi-wavelength photometric and spectroscopic observations covering a period of decade since outburst. We

Cay, Y. Z., et al.
We present the spectroscopic and photometric study of five intermediate-luminosity red transients (ILRTs), namely AT 2010dn, AT 2012jc, AT 2013la, AT 2013lb, and AT 2018aes. They share common observational properties and belon

Our current knowledge of cosmic star-formation history during the first two billion years (corresponding to redshift z >3) is mainly based on galaxies identified in rest-frame ultraviolet light. However, this population of galaxies is known to under-

Possible ~0.4 hour X-ray quasi-periodicity from an ultrasoft active galactic nucleus

Autor: Ning Jiang, Yongquan Xue, T. G. Wang, Liming Dou, J. R. Song, Luming Sun, Wenjie Zhang, Chengjin Jin, X. W. Shu

RX J1301.9+2747 is an ultrasoft active galactic nucleus (AGN) with unusual X-ray variability that is characterized by a long quiescent state and a short-lived flare state. The X-ray flares are found to recur quasi-periodically on a timescale of 13-20

The identification of high-redshift massive galaxies with old stellar populations may pose challenges to some models of galaxy formation. However, to securely classify a galaxy as quiescent, it is necessary to exclude significant ongoing star formati
