CHEERS Results from NGC 3393, II: Investigating the Extended Narrow Line Region using Deep Chandra Observations and Hubble Narrow Line Imaging
W. Peter Maksym, Giuseppina Fabbiano, Martin Elvis +5
The CHandra Extended Emission Line Region Survey (CHEERS) is an X-ray study of nearby active galactic nuclei (AGN) designed to take full advantage of Chandra's unique angular resol…
Mapping Seyfert and LINER Excitation Modes in the Inner kpc of NGC 3393
W. Peter Maksym, Giuseppina Fabbiano, Martin Elvis +5
We have mapped the extended narrow line region (ENLR) of NGC 3393 on scales of (kpc) from the nucleus using emission line images of H$α\,\lambd…
Hubble Space Telescope: Snapshot Survey for Resolved Companions of Galactic Cepheids
Nancy Remage Evans, Howard E. Bond, Gail H. Schaefer +4
We have conducted an imaging survey with the Hubble Space Telescope Wide Field Camera~3 (WFC3) of 70 Galactic Cepheids, typically within 1~kpc, with the aim of finding resolved phy…
Resolved Companions of Cepheids: Testing the Candidates with X-Ray Observations
Nancy Remage Evans, Ignazio Pillitteri, Scott Wolk +7
We have made {\it XMM-Newton\/} observations of 14 Galactic Cepheids that have candidate resolved (5$\arcsec$) companion stars based on our earlier {\it HST\/} WFC3 imaging s…
