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…
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…
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…
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…
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…
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…
Stellar bars form dark matter counterparts in TNG50
Neil Ash, Monica Valluri, Yingtian Chen +1
Dark matter (DM) bars that shadow stellar bars have been previously shown to form in idealized simulations of isolated disk galaxies. Here, we show that DM bars commonly occur in b…
Improved particle spray algorithm for modeling globular cluster streams
Yingtian Chen, Monica Valluri, Oleg Y. Gnedin +1
Stellar streams that emerge from globular clusters (GCs) are thin stellar structures spread along the orbits of progenitor clusters. Numerical modeling of these streams is essentia…
Forecasting the Population of Globular Cluster Streams in Milky Way-type Galaxies
Sarah Pearson, Ana Bonaca, Yingtian Chen +1
Thin stellar streams originating from globular clusters are among the most sensitive tracers of low-mass dark-matter subhalos. Joint analysis of the entire population of stellar st…
Galaxy assembly revealed by globular clusters
Yingtian Chen, Oleg Y. Gnedin
Many observable properties of globular clusters (GCs) provide valuable insights for unveiling the hierarchical assembly of their host galaxy. For the Milky Way (MW) in particular,…
Catalogue of model star clusters in the Milky Way and M31 galaxies
Yingtian Chen, Oleg Y. Gnedin
Detailed understanding of the formation and evolution of globular clusters (GCs) has been recently advanced through a combination of numerical simulations and analytical models. We…
Formation of globular clusters in dwarf galaxies of the Local Group
Yingtian Chen, Oleg Y. Gnedin
The existence of globular clusters (GCs) in a few satellite galaxies, and their absence in majority of dwarf galaxies, present a challenge for models attempting to understand the o…
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…
Effects of initial density profiles on massive star cluster formation in giant molecular clouds
Yingtian Chen, Hui Li, Mark Vogelsberger
We perform a suite of hydrodynamic simulations to investigate how initial density profiles of giant molecular clouds (GMCs) affect their subsequent evolution. We find that the star…
