Discovery of late-time X-ray flare and anomalous emission line enhancement after the nuclear optical outburst in a narrow-line Seyfert 1 Galaxy
W. J. Zhang, X. W. Shu, Z. F. Sheng +7
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 spe…
Long-term X-ray evolution of SDSS J134244.4+053056.1: A more than 18 year-old, long-lived IMBH-TDE candidate
J. S. He, L. M. Dou, Y. L. Ai +5
SDSS J134244.4+053056 is a tidal disruption event candidate with strong temporal coronal line emitters and a long fading, mid-infrared dust echo. We present detailed analyses of X-…
The Compact Structure of Radio-Loud Broad Absorption Line Quasars
Y. Liu, D. R. Jiang, T. G. Wang +1
We present the results of EVN+MERLIN VLBI polarization observations of 8 Broad Absorption Line (BAL) quasars at 1.6 GHz, including 4 LoBALs and 4 HiBALs with either steep or flat s…
A Population of Radio-loud Narrow Line Seyfert 1 Galaxies with Blazar-like Properties?
W. Yuan, H. Y. Zhou, S. Komossa +4
(abridged) We present a comprehensive study of a sample of 23 genuine radio-loud NLS1 galaxies which have the radio-loudness parameters greater than 100. The radio sources of the s…
Relativistic outflow in CXO CDFS J033260.0-274748
J. X. Wang, T. G. Wang, P. Tozzi +10
In this letter we report the detection of a strong and extremely blueshifted X-ray absorption feature in the 1 Ms Chandra spectrum of CXO CDFS J033260.0-274748, a quasar at z = 2.5…
Strong CaII absorption lines in the reddened quasar SDSS J23390912: Evidence of the collision/merger in the host galaxy?
Tinggui Wang, Xiaobo Dong, Hongyan Zhou +1
We report the detection of strong CaII/MgII absorption lines at the quasar redshift in the narrow line quasar SDSS J2339-0912 (z=0.6604). The quasar exhibits strong FeII, small Bal…
