A UV to X-ray view of soft excess in type 1 AGNs: I. sample selection and spectral profile
Shi-Jiang Chen, Jun-Xian Wang, Jia-Lai Kang +5
A core sample of 59 unobscured type 1 AGNs with simultaneous XMM-Newton X-ray and UV observations is compiled from archive to probe the nature of soft X-ray excess (SE). In the fir…
Could the inter-band lag of active galactic nucleus vary randomly?
Zhen-Bo Su, Zhen-Yi Cai, Jun-Xian Wang +18
The inter-band lags among the optical broad-band continua of active galactic nuclei (AGNs) have been intensively explored over the past decade. However, the nature of the lags rema…
A new timescale-mass scaling for the optical variation of active galactic nuclei across the intermediate-mass to supermassive scales
Zhen-Bo Su, Zhen-Yi Cai, Mouyuan Sun +3
Variability of active galactic nuclei (AGNs) has long been servicing as an essential avenue of exploring the accretion physics of black hole (BH). There are two commonly used metho…
