A re-emerging bright soft-X-ray state of the changing-look Active Galactic Nucleus 1ES~1927+654: a multi-wavelength view
Ritesh Ghosh, Sibasish Laha, Eileen Meyer +24
1ES1927+654 is a nearby active galactic nucleus that has shown an enigmatic outburst in optical/UV followed by X-rays, exhibiting strange variability patterns at timescales of mont…
Intermediate-Mass Black Holes: The Essential Population to Explore the Unified Model for Accretion and Ejection Processes
Xiaolong Yang, Jun Yang
We study radio and X-ray emissions from IMBHs and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicate…
The core starbursts of the galaxy NGC 3628: Radio very long baseline interferometry and X-ray studies
Xiaolong Yang, Ziwei Ou
We present radio very long baseline interferometry (VLBI) and X-ray studies of the starburst galaxy NGC 3628. The VLBI observation at 1.5 GHz reveals seven compact (0.77 parsec)…
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…
Intermediate-mass black holes: finding of episodic, large-scale and powerful jet activity in a dwarf galaxy
Jun Yang, Zsolt Paragi, Sándor Frey +10
Dwarf galaxies are characterised by a very low luminosity and low mass. Because of significant accretion and ejection activity of massive black holes, some dwarf galaxies also host…
The radio detection and accretion properties of the peculiar nuclear transient AT 2019avd
Yanan Wang, Ranieri D. Baldi, Santiago del Palacio +19
AT 2019avd is a nuclear transient detected from infrared to soft X-rays, though its nature is yet unclear. The source has shown two consecutive flaring episodes in the optical and…
