Optical Discovery of New and Candidate Galactic Supernova Remnants Plus Optical Imaging of the Monogem Supernova Remnant
Robert A. Fesen, Marcel Drechsler, Bray Falls +16
We report the discovery of new and candidate Galactic supernova remnants made through over 2000 hours of H and [O III] imaging using amateur class instrumentation. These nebulae…
SDSO1 is a Shocked Ghost Planetary Nebula in Front of M 31
Patrick Ogle, Mark Petersen, R. Michael Rich +12
We present new, deep narrowband imagery and discuss the nature of SDSO 1, the large [O III]-emitting nebula centered 1.5 degrees SE of M 31. We find strong evidence to support the…
Discovery of a [O III] Emission Shell Around the X-ray Binary CI Cam
Robert A. Fesen, Marcel Drechsler, Nicolas Martino +1
We report the serendipitous discovery of a emission shell brightest in [O III] centered on the X-ray binary B[e] star, CI Cameleopardalis (CI Cam). This shell, dete…
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…
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…
