An X-ray View of the Ambiguous Nuclear Transient AT2019pev
Zhefu Yu, C. S. Kochanek, S. Mathur +3
AT2019pev is a nuclear transient in a narrow-line Seyfert 1 galaxy at . The archival ultraviolet, optical and infrared data showed features of both tidal disruption events…
OzDES Reverberation Mapping Program: Lag recovery reliability for 6-year CIV analysis
Andrew Penton, Umang Malik, Tamara Davis +66
We present the statistical methods that have been developed to analyse the OzDES reverberation mapping sample. To perform this statistical analysis we have created a suite of custo…
OzDES Reverberation Mapping Program: Mg II Lags and R-L relation
Zhefu Yu, Paul Martini, A. Penton +55
The correlation between the broad line region radius and continuum luminosity ( relation) of active galactic nuclei (AGN) is critical for single-epoch mass estimates of superm…
Accretion disks, quasars and cosmology: meandering towards understanding
Bozena Czerny, Shulei Cao, Vikram Kumar Jaiswal +11
As Setti & Woltjer noted back in 1973, quasars could be used to construct the Hubble diagram but the actual application was not that straightforward. It took years to implement the…
The Intermediate-Mass Black Hole Reverberation Mapping Project: First Detection of Mid-Infrared Lags in Prototypical IMBHs in NGC 4395 and POX 52
Jingbo Sun, Hengxiao Guo, Wenwen Zuo +25
The search for robust evidence of intermediate-mass black holes (IMBHs) is crucial for understanding black hole seeding process and the formation of supermassive black holes in the…
The Sloan Digital Sky Survey Reverberation Mapping Project: Quasar Host Galaxies at from Image Decomposition
Minghao Yue, Linhua Jiang, Yue Shen +7
We present the rest-frame UV and optical photometry and morphology of low-redshift broad-line quasar host galaxies from the Sloan Digital Sky Survey Reverberation Mapping project.…
