Interpretation of the X-ray Spectral Variation of 1H0707-495 with a Variable Double Partial Covering Model
Misaki Mizumoto, Ken Ebisawa, Hiroaki Sameshima
The Narrow-line Seyfert 1 galaxy 1H0707-495 is known to exhibit significant X-ray spectral variations. Its X-ray energy spectrum is characterized by a strong soft excess emission,…
Statistical Properties of Multi-epoch Spectral Variability of SDSS Stripe82 Quasars
Mitsuru Kokubo, Tomoki Morokuma, Takeo Minezaki +4
We investigate the UV-optical (longward of Ly 1216Å) spectral variability of nearly 9000 quasars () using multi-epoch photometric data within the SDSS Stripe 82 region. T…
