Shocks, Winds, and a Torus: The Large Binocular Telescope Interferometer (LBTI) Resolves the Active Nucleus of NGC 4151
Jacob W. Isbell, Steve Ertel, Makoto Kishimoto +12
We present mid-infrared (MIR) observations of the Seyfert 1 galaxy NGC 4151 using the Large Binocular Telescope Interferometer (LBTI). We took open-loop Fizeau images with 66-104 m…
Far UV and Optical Emissions from Three Very Large Supernova Remnants Located at Unusually High Galactic Latitudes
Robert A. Fesen, Marcel Drechsler, Kathryn E. Weil +9
Galactic supernova remnants (SNRs) with angular dimensions greater than a few degrees are relatively rare, as are remnants located more than ten degrees off the Galactic plane. Her…
The Spatial and Emission Properties of the Large [O III] Emission Nebula Near M31
Robert A. Fesen, Stefan Kimeswenger, J. Michael Shull +8
Drechsler et al. (2023) reported the unexpected discovery of a 1.5 degree long [O III] emission nebula 1.2 degrees southeast of the M31 nucleus. Here we present additional images o…
YY Hya and its interstellar environment
Stefan Kimeswenger, John R. Thorstensen, Robert A. Fesen +7
During a search for previously unknown Galactic emission nebulae, we discovered a faint 36' diameter Halpha emission nebula centered around the periodic variable YY Hya. Although t…
Deep Optical Emission-Line Images of Nine Known and Three New Galactic Supernova Remnants
Robert A. Fesen, Marcel Drechsler, Xavier Strottner +14
Deep optical emission-line images are presented for nine known plus three new Galactic supernova remnants (SNRs), all but one having at least one angular dimension greater than one…
