Intra-Day Variability Observations of Two Dozens of Blazars at 4.8 GHz
Xiang Liu, Xin Wang, Ning Chang +4
Two dozens of radio loud active galactic nuclei (AGNs) have been observed with Urumqi 25 m radio telescope in order to search for intra-day variability (IDV). The target sources ar…
East Asian VLBI Network Observations of Active Galactic Nuclei Jets: Imaging with KaVA+Tianma+Nanshan
Yuzhu Cui, Kazuhiro Hada, Motoki Kino +74
The East Asian very-long-baseline interferometry (VLBI) Network (EAVN) is a rapidly evolving international VLBI array that is currently promoted under joint efforts among China, Ja…
A compact core-jet structure in the changing-look Seyfert NGC 2617
Jun Yang, Zsolt Paragi, Robert J. Beswick +9
The nearby face-on spiral galaxy NGC 2617 underwent an unambiguous 'inside-out' multi-wavelength outburst in Spring 2013, and a dramatic Seyfert type change probably between 2010 a…
A parsec-scale faint jet in the nearby changing-look Seyfert galaxy Mrk 590
J. Yang, I. van Bemmel, Z. Paragi +9
Broad Balmer emission lines in active galactic nuclei (AGN) may display dramatic changes in amplitude, even disappearance and re-appearance in some sources. As a nearby galaxy at a…
Radio activity of supermassive black holes with extremely high accretion rates
Xiaolong Yang, Su Yao, Jun Yang +8
Radio emission from the high- and super-Eddington accreting active galactic nuclei (AGNs) has various origins: a persistent jet, the magnetized corona and the wind-like outflows. I…
Spatially-resolved Stellar Population Properties of the M 51-NGC 5195 System from Multi-wavelength Photometric Data
Peng Wei, Hu Zou, Lin Lin +5
Using multi-band photometric images of M 51 and its companion NGC 5195 from ultraviolet to optical and infrared, we investigate spatially resolved stellar population properties of…
