2023年7月12日 · 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 velocity and flux measurements from low-dispersion spectra. Independent sets of [O III] images show ...
Discovery of Extensive [O III] Emission Near M31 - NASA/ADS
We report the discovery of a broad, 1.°5 long filamentary [O III] emission nebulosity some 1.°2 southeast of the M31 nucleus. This nebulosity is not detected in Hα and has no obvious emission counterparts in X-ray, UV, optical, infrared, and radio surveys.
