Improving the Flux Calibration in Reverberation Mapping by Spectral Fitting: Application to the Seyfert Galaxy MCG--6-30-15
Chen Hu, Jian-Min Wang, Luis C. Ho +4
We propose a method for the flux calibration of reverberation mapping spectra based on accurate measurement of [O III] emission by spectral fitting. The method can achieve…
Subdwarf B stars from the common envelope ejection channel
H. Xiong, X. Chen, P. Podsiadlowski +2
From the canonical binary scenario, the majority of sdBs are produced from low-mass stars with degenerate cores where helium is ignited in a way of flashes. Due to numerical diffic…
A Non-parametric Approach to Constrain the Transfer Function in Reverberation Mapping
Yan-Rong Li, Jian-Min Wang, Jin-Ming Bai
Broad emission lines of active galactic nuclei stem from a spatially extended region (broad-line region, BLR) that is composed of discrete clouds and photoionized by the central io…
Reverberation Mapping of the Broad-line Region in NGC 5548: Evidence for Radiation Pressure?
Kai-Xing Lu, Pu Du, Chen Hu +8
NGC 5548 is the best-observed reverberation-mapped active galactic nucleus with long-term, intensive monitoring. Here we report results from a new observational campaign between Ja…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. V. A New Size-Luminosity Scaling Relation for the Broad-Line Region
Pu Du, Kai-Xing Lu, Zhi-Xiang Zhang +12
This paper reports results of the third-year campaign of monitoring super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs) between 2014-2015. Ten…
A note on periodicity of long-term variations of optical continuum in active galactic nuclei
Kai-Xing Lu, Yan-Rong Li, Shao-Lan Bi +1
Graham et al. found a sample of active galactic nuclei (AGNs) and quasars from the Catalina Real-time Transient Survey (CRTS) that have long-term periodic variations in optical con…
