New dwarfs around the curly spiral galaxy M63
I. D. Karachentsev, F. Neyer, R. Späni +1
We present a deep (50 hours exposed) image of the nearby spiral galaxy M 63 (NGC 5055), taken with a 0.14-m aperture telescope. The galaxy halo exhibits the known very faint system…
On the nature of a shell of young stars in the outskirts of the Small Magellanic Cloud
David Martinez-Delgado, A. Katherina Vivas, Eva K. Grebel +35
Understanding the evolutionary history of the Magellanic Clouds requires an in-depth exploration and characterization of the stellar content in their outer regions, which ultimatel…
An overmassive Dark Halo around an Ultra-diffuse Galaxy in the Virgo Cluster
Michael A. Beasley, Aaron J. Romanowsky, Vincenzo Pota +4
Ultra diffuse galaxies (UDGs) have the sizes of giant galaxies but the luminosities of dwarfs. A key to understanding their origins comes from their total masses, but their low sur…
Low Surface Brightness Imaging of the Magellanic System: Imprints of Tidal Interactions between the Clouds in the Stellar Periphery
Gurtina Besla, David Martinez-Delgado, Roeland P. van der Marel +5
We present deep optical images of the Large and Small Magellanic Clouds (LMC and SMC) using a low cost telephoto lens with a wide field of view to explore stellar substructure in t…
New Low Surface Brightness Dwarf Galaxies Detected Around Nearby Spirals
I. D. Karachentsev, P. Riepe, T. Zilch +14
We conduct a survey of low surface brightness (LSB) satellite galaxies around the Local Volume massive spirals using long exposures with small amateur telescopes. We identified 27…
Three low surface brightness dwarfs discovered around NGC 4631
Igor D. Karachentsev, Dirk Bautzmann, Fabian Neyer +4
We report the discovery of three low surface brightness companions to the spiral galaxy NGC 4631, made with small amateur telescopes. Assuming their distances to be 7.4 Mpc, the sa…
