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…
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…
