X-ray Emission Properties of a Compact Symmetric Object Sample
Ying-Ying Gan, Su Yao, Tan-Zheng Wu +2
We present a comprehensive analysis of the X-ray observations obtained from \xmm\, and \chandra\, for a sample of bona-fide Compact Symmetric Objects (CSOs) to investigate their X-…
First deep X-ray observations of the Fermi-detected steep-spectrum source and radio-loud NLS1 galaxy 3C 286
Su Yao, S. Komossa, A. Kraus +1
A well-known calibrator source in radio astronomy, 3C 286 (), is a compact steep-spectrum (CSS) radio source and spectroscopically classified as a narrow-line Seyfert 1 (NL…
On the nature of the radio calibrator and gamma-ray emitting NLS1 galaxy 3C 286 and its multiwavelength variability
S. Komossa, S. Yao, D. Grupe +1
The quasar 3C 286, a well-known calibrator source in radio astronomy, was found to exhibit exceptional multiwavelength properties. Its rich and complex optical emission-line spectr…
Multiwavelength variability of gamma-ray emitting narrow-line Seyfert 1 galaxies
Su Yao, S. Komossa
As one of the drivers of feedback in active galactic nuclei (AGNs), the jets launched from supermassive black holes (SMBHs) are important for understanding the co-evolution of SMBH…
Unveiling the small-scale jets in the rapidly growing supermassive black hole IZw1
Xiaolong Yang, Su Yao, Luigi C. Gallo +10
Accretion of black holes at near-Eddington or super-Eddington rates is the most powerful episode that drives black hole growth, and it may work in several types of objects. However…
MOMO VI: Multifrequency radio variability of the blazar OJ 287 from 2015-2022, absence of predicted 2021 precursor-flare activity, and a new binary interpretation of the 2016/2017 outburst
S. Komossa, A. Kraus, D. Grupe +12
Based on our dedicated Swift monitoring program, MOMO, OJ 287 is one of the best-monitored blazars in the X-ray--UV--optical regime. Here, we report results from our accompanying,…
