I update the GC formation model developed by Choksi & Gnedin (2019) by adding spatial information to the modeled GC system.
Together with Hui Li and Mark Vogelsberger, I perform a suite of simulations to investigate the effects of initial density profiles on the evolution of star clusters in GMCs. We find that the uniform profile follows a "hierarchical" cluster formation mode, while the steep power-law profiles show an "accretion" dominated mode. These two cluster formation modes lead to different proprieties of the most massive clusters in GMCs. See our first paper (Chen, Li and Vogelsberger 2021) for details.
"Hierarchical" (left) and "accretion" (right) modes for cluster formation.
Based on the cosmic light speed variation, I found a novel pre-burst stage for GRBs. I also employed a primary clustering method to classify this stage with the data from the Fermi observatory.
