Discovery of a [O III] Emission Shell Around the X-ray Binary CI Cam

Autor: Fesen, Robert A., Drechsler, Marcel, Martino, Nicolas, Sainty, Yann

We report the serendipitous discovery of a $8' \times 12'$ emission shell brightest in [O III] centered on the X-ray binary B[e] star, CI Cameleopardalis (CI Cam). This shell, detected during a survey of optical emission associated with the Galactic

Deep Optical Emission-Line Images of Nine Known and Three New Galactic Supernova Remnants

Autor: Fesen, Robert A., Drechsler, Marcel, Strottner, Xavier, Falls, Bray, Sainty, Yann, Martino, Nicolas, Galli, Richard, Ludgate, Mathew, Blauensteiner, Markus, Reich, Wolfgang, Walker, Sean, di Cicco, Dennis, Mittelman, David, Morgan, Curtis, Kaeouach, Aziz Ettahar, Rupert, Justin, Benkhaldoun, Zouhair

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 degree. Wide-field images taken in H$\alpha$ and [O III] $\lambda$500

The Spatial and Emission Properties of the Large [O III] Emission Nebula Near M31

Autor: Fesen, Robert A., Kimeswenger, Stefan, Shull, J. Michael, Drechsler, Marcel, Strottner, Xavier, Sainty, Yann, Falls, Bray, Vergnes, Christophe, Martino, Nicolas, Walker, Sean, Rupert, Justin

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 of this large emission structure, called SDSO, along with radial veloci
