Evidence for the connection between star formation rate and evolutionary phases of quasars
Zhifu Chen, Zhicheng He, Luis C. Ho +5
Both theory and observations suggest that outflows driven by an active central supermassive black hole (SMBH) has a feedback effect on shaping the global properties of the host gal…
The Disk Veiling Effect of the Black Hole Low-Mass X-ray Binary A0620-00
Wan-Min Zheng, Qiaoya Wu, Jianfeng Wu +15
The optical light curves of quiescent black hole low-mass X-ray binaries often exhibit significant non-ellipsoidal variabilities, showing the photospheric radiation of the companio…
Metallicity in Quasar Broad Line Regions at Redshift 6
Shu Wang, Linhua Jiang, Yue Shen +10
Broad line regions (BLRs) in high-redshift quasars provide crucial information of chemical enrichment in the early universe. Here we present a study of BLR metallicities in 33 quas…
A New Iron Emission Template for Active Galactic Nuclei. I. Optical Template for the H region
Daeseong Park, Aaron J. Barth, Luis C. Ho +1
We present a new empirical template for iron emission in active galactic nuclei (AGN) covering the A range. The new template is based on a spectrum of the narrow-line S…
DXML: Distributed Extreme Multilabel Classification
Pawan Kumar
As a big data application, extreme multilabel classification has emerged as an important research topic with applications in ranking and recommendation of products and items. A sca…
Detection of a Parsec-Scale Jet in a Radio-Quiet Narrow-Line Seyfert 1 Galaxy with Highly Accreting Supermassive Black Hole
Su Yao, Xiaolong Yang, Minfeng Gu +7
The jet in active galactic nuclei (AGN) is a key ingredient in understanding the co-evolution of galaxies and their central supermassive black holes (SMBHs). Unfortunately, the mec…
