Nonlinear Color-Metallicity Relations of Globular Clusters. IX. Different Radial Number Density Profiles between Blue and Red Clusters
Sang-Yoon Lee, Chul Chung, Suk-Jin Yoon
The optical colors of globular clusters (GCs) in most large early-type galaxies are bimodal. Blue and red GCs show a sharp difference in the radial profile of their surface number…
Yonsei Evolutionary Population Synthesis (YEPS) Model. III. Surface Brightness Fluctuation of Normal and Helium-enhanced Simple Stellar Populations
Chul Chung, Suk-Jin Yoon, Hyejeon Cho +2
We present an evolutionary population synthesis model of the surface brightness fluctuation (SBF) for normal and He-enriched simple stellar populations (SSPs). While our SBF model…
MOCCA SURVEY Database I: Binary Black Hole Mergers from Globular Clusters with Intermediate Mass Black Holes
Jongsuk Hong, Abbas Askar, Mirek Giersz +2
The dynamical formation of black hole binaries in globular clusters that merge due to gravitational waves occurs more frequently in higher stellar density. Meanwhile, the probabili…
Starbursting Nuclei in Old Dwarf Galaxies
Sanjaya Paudel, Suk-Jin Yoon
Nuclei of early-type dwarf galaxies (dEs) are usually younger than the galaxy main body, and such discrepancy in age has been a puzzle. To explore the origin of young nuclei in dEs…
Living with Neighbors. III. Scrutinizing the SpinOrbit Alignment of Interacting Dark Matter Halo Pairs
Sung-Ho An, Juhan Kim, Jun-Sung Moon +1
We present that the spinorbit alignment (SOA; i.e., the angular alignment between the spin vector of a halo and the orbital angular momentum vector of its neighbor) provides an…
Introducing a new multi-particle collision method for the evolution of dense stellar systems. Crash-test N-body simulations
Pierfrancesco Di Cintio, Mario Pasquato, Hyunwoo Kim +1
Stellar systems are broadly divided into collisional and non-collisional. The latter are large-N systems with long relaxation timescales and can be simulated disregarding two-body…
