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…

Continuous star cluster formation in the spiral NGC 45

Marcelo Mora, Soeren S. Larsen, Markus Kissler-Patig

We determined ages for 52 star clusters with masses < 10^6 solar masses in the low surface brightness spiral galaxy NGC 45. Four of these candidates are old globular clusters locat…

Exploring the stellar streams and satellites around the giant low surface brightness galaxy Malin 1

Roy O. E. Bustos-Espinoza, Matias Blaña, Gaspar Galaz +7

Giant Low Surface Brightness galaxies (gLSBGs), such as Malin 1, host extended stellar and gaseous discs exceeding in radius. Their formation and evolution remai…

The giant low surface brightness galaxy Malin 1: new constraints for its molecular gas mass from GBT/ARGUS observations

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…

Colors and Dynamics of a Near-Sun Orbital Asteroid Family: 2021 PH27 and 2025 GN1

Scott Sheppard, Henry Hsieh, Petr Pokorny +6

We observed the dynamically similar near-Sun asteroids 2021 PH27 and 2025 GN1 for their optical colors. These objects have the lowest known semi-major axes of any asteroids. 2021 P…
