Varstrometry Selected Radio-Loud Candidates of Dual and Off-Nucleus Quasars at Sub-kpc Scales
Hao-Chen Wang, Jun-Xian Wang, Min-Feng Gu +1
Dual super massive black holes at sub-kpc to kpc scales, the product of galaxy mergers, are progenitors of eventually coalescing binary SMBHs. If both or one of the dual SMBHs are…
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…
Exploring the Connection between UV/Optical Variations and Radio Emission in Radio-Quiet Quasars: Clues on Radio Emission Origin
Mai Liao, Junxian Wang, Wenyong Kang +1
The radio emission in radio-quiet quasars (RQQs) has been a long mystery and its physical origin remains unclear. In a previous work we find UV/optical more variable quasars have s…
Investigations on the optical properties and X-ray emission in compact radio AGN
Mai Liao, Minfeng Gu
Compact radio active galactic nuclei (compact radio AGN) are compact ( 20 kpc), powerful radio sources. Currently, the preferred scenario is that they are at the early stage…
The X-ray emission in young radio AGNs
Mai Liao, Minfeng Gu, Minhua Zhou +1
In this work, we investigated the X-ray emission for a sample of young radio AGNs by combining their data from Chandra/XMM-Newton and at other wavebands. We find strong correlation…
Investigation on Young radio AGNs based on SDSS spectroscopy
Mai Liao, Minfeng Gu
The Gigahertz Peaked Spectrum (GPS) sources, Compact Steep Spectrum (CSS) radio sources, and High Frequency Peakers (HFP) radio sources are thought to be young radio AGNs, at the e…
The Optical Variability of SDSS Quasars from Multi-epoch Spectroscopy. III. A Sudden UV Cutoff in Quasar SDSS J2317+0005
Hengxiao Guo, Matthew A. Malkan, Minfeng Gu +6
We have collected near-infrared to X-ray data of 20 multi-epoch heavily reddened SDSS quasars to investigate the physical mechanism of reddening. Of these, J2317+0005 is found to b…
