Mapping Excitation in the Inner Regions of the Planetary Nebula NGC 5189 using HST WFC3 Imaging
Ashkbiz Danehkar, Margarita Karovska, W. Peter Maksym +1
The planetary nebula (PN) NGC 5189 around a Wolf-Rayet [WO] central star demonstrates one of the most remarkable complex morphologies among PNe with many multi-scale structures, sh…
Joint NuSTAR and Chandra analysis of the obscured quasar in IC 2497 - Hanny's Voorwerp system
Lia F. Sartori, Kevin Schawinski, Michael J. Koss +9
We present new Nuclear Spectroscopic Telescope Array (NuSTAR) observations of the core of IC 2497, the galaxy associated with Hanny's Voorwerp. The combined fits of the Chandra (0.…
Using Strong Gravitational Lensing to Identify Fossil Group Progenitors
Lucas E. Johnson, Jimmy A. Irwin, Raymond E. White +5
Fossil galaxy systems are classically thought to be the end result of galaxy group/cluster evolution, as galaxies experiencing dynamical friction sink to the center of the group po…
A Multi-wavelength Study of the Turbulent Central Engine of the Low-mass AGN hosted by NGC404
Kristina Nyland, Timothy A. Davis, Dieu D. Nguyen +9
The nearby dwarf galaxy NGC404 harbors a low-luminosity active galactic nucleus (AGN) powered by the lowest-mass (< 150,000 solar-masses) central massive black hole (MBH) with a dy…
Discovery of Kiloparsec Extended Hard X-ray Continuum and Fe K alpha from the Compton Thick AGN ESO428-G014
G. Fabbiano, M. Elvis, A. Paggi +5
We report the discovery of kpc-scale diffuse emission in both the hard continuum (3-6 keV) and in the Fe K alpha line in the Compton Thick (CT) Seyfert galaxy ESO428-G014. This ext…
X-ray emission from the nuclear region of Arp 220
Alessandro Paggi, Giuseppina Fabbiano, Guido Risaliti +6
We present an imaging and spectral analysis of the nuclear region of the ULIRG merger Arp 220, using deep \textit{Chandra}-ACIS observations summing up to \(\sim 300\mbox{ ks}\). N…
