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.…
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…
Enabling New ALMA Science with Improved Support for Time-Domain Observations
Kate D. Alexander, Edo Berger, Geoff Bower +34
While the Atacama Large Millimeter/submillimeter Array (ALMA) is a uniquely powerful telescope, its impact in certain fields of astrophysics has been limited by observatory policie…
