Stellar tidal streams around nearby spiral galaxies with deep imaging from amateur telescopes

David Martinez-Delgado, Michael Stein, Joanna D. Sakowska +26

Tidal interactions between massive galaxies and their satellites are fundamental processes in a Universe with L-Cold Dark Matter cosmology, redistributing material into faint featu…

Modeling the Baryon Cycle in Low Mass Galaxy Encounters: the Case of NGC 4490 & NGC 4485

Sarah Pearson, George C. Privon, Gurtina Besla +6

Discoveries of low mass galaxy pairs and groups are increasing. Studies indicate that dwarf galaxy pairs are gas rich in the field and exhibit elevated star formation rates, sugges…

Stellar Tidal Streams in External Galaxies

Jeffrey L. Carlin, Rachael L. Beaton, David Martinez-Delgado +1

To place the highly substructured stellar halos of the Milky Way and M31 in a larger context of hierarchical galaxy formation, it is necessary to understand the prevalence and prop…
