Wide-field, multi-band surveys now detect millions of unresolved sources in nearby galaxy clusters, yet separating globular clusters (GCs) from foreground stars and background gala…
The contribution of the color space in LSST-like photometry for the selection of extragalactic globular cluster candidates
Nicholas Schweder-Souza, Ana L. Chies-Santos, Rafael S. de Souza +16
Globular clusters (GCs) are excellent tracers of their host galaxies' evolutionary histories. Traditional methods for identifying GCs in galaxies rely on cuts over photometric cata…
Diving into dangerous tides: The impact of galaxy cluster tidal environments on satellite galaxy mass densities
Matias Blaña, Thomas H. Puzia, Yasna Ordenes-Briceño +8
Satellite galaxies endure powerful environmental tidal forces that drive mass stripping of their outer regions. Consequently, satellites located in central regions of galaxy cluste…

Manuel Cavieres, Julio Chanamé, Camila Navarrete +6
The infall of the Large Magellanic Cloud (LMC) into the Milky Way's halo impacts the distribution of stars and dark matter in our Galaxy. Mapping the observational consequences of…
A MUSE View of the Core of the Giant Low Surface Brightness Galaxy Malin 1

Gaspar Galaz, David T. Frayer, Matias Blaña +8
We report on results from GBT/ARGUS CO(1-0) observations for the giant low surface brightness galaxy Malin 1, which allow us to determine an upper limit for its CO mass, and…

BUDDI-MaNGA II: The Star-Formation Histories of Bulges and Discs of S0s
Evelyn J. Johnston, Boris Häußler, Keerthana Jegatheesan +7
Many processes have been proposed to explain the quenching of star formation in spiral galaxies and their transformation into S0s. These processes affect the bulge and disc in diff…
Extending the evolution of the stellar mass-size relation at to low stellar mass galaxies from HFF and CANDELS
Kalina V. Nedkova, Boris Häußler, Danilo Marchesini +23
We reliably extend the stellar mass-size relation over to low stellar mass galaxies by combining the depth of Hubble Frontier Fields (HFF) with the large volume c…
