Spatially resolved BPT mapping of nearby Seyfert 2 galaxies
Jingzhe Ma,W. Peter Maksym,Giuseppina Fabbiano,Martin Elvis,Thaisa Storchi-Bergmann,Margarita Karovska,Junfeng Wang,A. Travascio +7 more
TL;DR: In this article, the authors presented spatially resolved BPT mapping of the extended narrow line regions (ENLRs) of seven nearby Seyfert 2 galaxies, using HST narrow band filter imaging.
Journal ArticleDOI
Mapping Seyfert and LINER Excitation Modes in the Inner kpc of NGC 3393
W. Peter Maksym,Giuseppina Fabbiano,Martin Elvis,Margarita Karovska,Alessandro Paggi,John C. Raymond,Junfeng Wang,Thaisa Storchi-Bergmann +7 more
TL;DR: In this paper, the extended narrow line region (ENLR) of NGC 3393 was mapped onto a spatially resolved Baldwin-Phillips-Terlevich (BPT) diagram to investigate the impact of feedback from a Compton-thick AGN on its circumnuclear ISM.
Journal ArticleDOI
Direct Detection of the Close Companion of Polaris with the Hubble Space Telescope
Nancy Remage Evans,Gail Schaefer,Howard E. Bond,Giuseppe Bono,Margarita Karovska,Edmund P. Nelan,Dimitar Sasselov,Brian D. Mason +7 more
TL;DR: Using the High Resolution Channel of the Advanced Camera for Surveys onboard the Hubble Space Telescope (HST) at a wavelength of ~2255\AA, a second HST observation 1.04 yr later confirmed orbital motion in a retrograde direction as discussed by the authors.

TL;DR: The first release of the Chandra Source Catalog (CSC) contains ~95,000 X-ray sources in a total area of 0.75% of the entire sky, using data from ~3900 separate ACIS observations of a multitude of different types of different sources as discussed by the authors.
Journal ArticleDOI
