X-ray view of a merging supermassive black hole binary candidate SDSSJ1430+2303: Results from the first ~200 days of observations
Liming Dou, Ning Jiang, Tinggui Wang +7
Recently we discovered an unprecedented supermassive black hole binary (SMBHB) candidate in the nearby Seyfert galaxy SDSS J1430+2303, which is predicted to merge within three year…
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-…
Multi-wavelength observations of the BL Lac object Fermi J1544-0649: one year after its awakening
P. H. T. Tam, P. S. Pal, Y. D. Cui +15
We report observations of a transient source \fermi\ from radio to \grs. \fermi\ was discovered by the {\it Fermi-LAT} in May 2017. Follow-up {\it Swift-XRT} observations revealed…
X-ray spectral and temporal analysis of Narrow Line Seyfert 1 galaxy Was 61
Liming Dou, Ting-Gui Wang, Yanli Ai +3
We present an analysis of spectrum and variability of the bright reddened narrow line Seyfert 1 galaxy Was~61 using 90 ks archival {\it XMM-Newton} data. The X-ray spectrum in 0.2-…
An Unobscured type II quasar candidate: SDSS J012032.19-005501.9
Y. Li, W. Yuan, H. Y. Zhou +4
We report the finding of an unobscured type II Active Galactic Nuclei (AGN) candidate, SDSS J012032.19-005501.9 at a relatively high redshift of 0.601,which shows a number of unusu…
