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…
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…
Three-dimensional hydrodynamical models of wind and outburst-related accretion in symbiotic systems
M. de Val-Borro, M. Karovska, D. D. Sasselov +1
Gravitationally focused wind accretion in binary systems consisting of an evolved star with a gaseous envelope and a compact accreting companion is a possible mechanism to explain…
