Resolving Star Cluster Formation in Galaxy Simulations with Cosmic Ray Feedback

Brandon Sike, Mateusz Ruszkowski, Oleg Y. Gnedin +4

Star clusters host the massive stars responsible for feedback in star-forming galaxies. Stellar feedback shapes the interstellar medium (ISM), affecting the formation of future sta…

Tracing the relic nature of compact galaxies through their globular cluster systems

Micheli T. Moura, Ana L. Chies-Santos, Cristina Furlanetto +6

We investigate the synthetic model of globular cluster (GC) systems of 17 compact massive galaxies (CMGs) from the Illustris TNG100 simulation to explore their connection with mass…

Catalog of Mock Stellar Streams in Milky Way-Like Galaxies

Colin Holm-Hansen, Yingtian Chen, Oleg Y. Gnedin

Dynamically cold stellar streams from tidally dissolved globular clusters (GCs) serve as excellent tools to measure the Galactic mass distribution and show promise to probe the nat…

StarStream on Gaia: Stream discovery and mass loss rate of globular clusters

Yingtian Chen, Oleg Y. Gnedin, Adrian M. Price-Whelan

We apply the automatic stellar stream detection algorithm StarStream to Gaia Data Release 3 and identify 87 stellar streams associated with Galactic globular clusters (GCs), includ…

StarStream: Automatic detection algorithm for stellar streams

Yingtian Chen, Oleg Y. Gnedin, Adrian M. Price-Whelan +1

The Gaia mission has led to the discovery of over 100 stellar streams in the Milky Way, most of which likely originated from globular clusters (GCs). As the upcoming wide-field sur…

Stellar streams reveal the mass loss of globular clusters

Yingtian Chen, Hui Li, Oleg Y. Gnedin

Globular cluster (GC) streams, debris of stars that tidally stripped from their progenitor GCs, have densities that correlate positively with the GC mass loss rate. In this work, w…
