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…
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 MDW Hα Sky Survey: Data Release 0
Noor Aftab, Xunhe, Zhang +10
The Mittelman-di Cicco-Walker (MDW) H Sky Survey is an autonomously-operated and ongoing all-sky imaging survey in the narrowband H wavelength. The survey was founded by am…
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…
G107.0+9.0: A New Large Optically Bright, Radio and X-Ray Faint Galactic Supernova Remnant in Cepheus
Robert A. Fesen, Kathryn E. Weil, John C. Raymond +7
Wide-field H-alpha images of the Galactic plane have revealed a new supernova remnant (SNR) nearly three degrees in diameter centred at l = 107.0, b = +9.0. Deep and higher resolut…
The MDW Hα Sky Survey: Data Release 1
Noor Aftab, Xunhe, Zhang +7
The Mittelman-di Cicco-Walker (MDW) H Sky Survey is an autonomously-operated all-sky narrow-band (3nm) H imaging survey. The survey was founded by amateur astronomers and t…
