Ultrafaint Dwarf Galaxy Candidates in the M81 Group: Signatures of Group Accretion
Eric F. Bell, Adam Smercina, Paul A. Price +8
The faint and ultrafaint dwarf galaxies in the Local Group form the observational bedrock upon which our understanding of small-scale cosmology rests. In order to understand whethe…
Testing Feedback from Star Clusters in Simulations of the Milky Way Formation
Gillen Brown, Oleg Y. Gnedin
We present a suite of galaxy formation simulations that directly model star cluster formation and disruption. Starting from a model previously developed by our group, here we intro…
Optical and X-ray GRB Fundamental Planes as Cosmological Distance Indicators
Maria Giovanna Dainotti, Via Nielson, Giuseppe Sarracino +5
Gamma-Ray Bursts (GRBs), can be employed as standardized candles, extending the distance ladder beyond Supernovae Type Ia (SNe Ia, ). We standardize GRBs using the 3D funda…
Modeling the kinematics of globular cluster systems
Yingtian Chen, Oleg Y. Gnedin
Globular clusters (GCs) are old massive star clusters that serve as `fossils' of galaxy formation. The advent of Gaia observatory has enabled detailed kinematics studies of the Gal…
Tidal disruption of star clusters in galaxy formation simulations
Xi Meng, Oleg Y. Gnedin
We investigate the evolution of the tidal field experienced by massive star clusters using cosmological simulations of Milky Way-sized galaxies. Clusters in our simulations experie…
