    Discovery of an Ultra-diffuse Galaxy in the Pisces--Perseus Supercluster
    We report the discovery of DGSAT I, an ultra-diffuse, quenched galaxy located 10.°4 in projection from the Andromeda galaxy (M31). This low-surface brightness...

    Discovery of an X-Ray Photoionized Optical Nebula and a Radio Nebula Associated with the ULX NGC 4861 X-1
    We have conducted long-slit spectroscopic observations and analyzed archival radio data for the ultraluminous X-ray source (ULX) NGC 4861 X-1. Our spectral line...

    Discovery of disc truncations above the galaxies' mid-plane in Milky Way-like galaxies
    Disc truncations are the closest feature to an edge that galaxies have, but the nature of this phenomenon is not yet understood. In this paper we explore the...

    Discovery of Faint Double-peak Hα Emission in the Halo of Low Redshift Galaxies
    Aimed at the detection of cosmological gas being accreted onto galaxies in the local universe, we examined the Hα emission in the halo of 164 galaxies in the...
