Fading AGN Candidates: AGN Histories and Outflow Signatures
William C. Keel, Chris J. Lintott, W. Peter Maksym +12
We consider energy budgets and radiative history of 8 fading AGN, identified from mismatch between the ionizion of very extended (>10 kpc) ionized clouds and the luminosity of the…
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…
Ultraluminous X-ray bursts in two ultracompact companions to nearby elliptical galaxies
Jimmy A. Irwin, W. Peter Maksym, Gregory R. Sivakoff +8
An X-ray flaring source was found near the galaxy NGC 4697. Two flares were seen, separated by four years. The flux increased by a factor of 90 on a timescale of about one minute.…
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…
An Ultraviolet Spectrum of the Tidal Disruption Flare ASASSN-14li
S. Bradley Cenko, Antonino Cucchiara, Nathaniel Roth +18
We present a Hubble Space Telescope STIS spectrum of ASASSN-14li, the first rest-frame UV spectrum of a tidal disruption flare (TDF). The underlying continuum is well fit by a blac…
Extended X-ray emission in the IC 2497 - Hanny's Voorwerp system: energy injection in the gas around a fading AGN
Lia F. Sartori, Kevin Schawinski, Michael Koss +6
We present deep Chandra X-ray observations of the core of IC 2497, the galaxy associated with Hanny's Voorwerp and hosting a fading AGN. We find extended soft X-ray emission from h…
