The kpc Scale Fe K Emission in the Compton Thin Seyfert 2 Galaxy NGC 4388 resolved by Chandra
Huili Yi, Junfeng Wang, Xinwen Shu +4
We present Chandra imaging and spectral observations of Seyfert 2 galaxy NGC 4388. Three extended X-ray structures around the nucleus on kpc scale are well imaged, allowing an in-d…
An X-ray View of Two Infrared Dark Clouds G034.43+00.24 and G035.39-00.33
Hanbo Yu, Junfeng Wang, Jonathan C. Tan
We present a high spatial resolution Chandra X-ray study of two Infrared Dark Clouds (IRDCs), G034.43+00.24 and G035.39-00.33, which are expected to be in the early phases of star…
Revisiting the complex nuclear region of NGC 6240 with Chandra
G. Fabbiano, A. Paggi, M. Karovska +3
We present a reanalysis of the cumulative ACIS S Chandra data set pointed at the double AGNs of the NGC 6240 merging galaxy, focusing on the hard energy bands containing the hard s…
Spatially resolved BPT mapping of nearby Seyfert 2 galaxies
Jingzhe Ma, W. Peter Maksym, G. Fabbiano +5
We present spatially resolved BPT mapping of the extended narrow line regions (ENLRs) of seven nearby Seyfert 2 galaxies, using HST narrow band filter imaging. We construct the BPT…
Phase-dependent study of near-infrared disk emission lines in LB-1
Jifeng Liu, Zheng Zheng, Roberto Soria +19
The mass, origin and evolutionary stage of the binary system LB-1 has been the subject of intense debate, following the claim that it hosts an 70 black hole, in st…
Jet Properties of Compact Steep-Spectrum Sources and an Eddington-Ratio-Driven Unification Scheme of Jet Radiation in Active Galactic Nuclei
Jin Zhang, Hai-Ming Zhang, Ying-Ying Gan +3
Compact steep-spectrum sources (CSSs) likely represent a population of young radio-loud active galactic nuclei (AGNs) and have been identified as gamma-ray emitting sources. We pre…
