Forming Blue Compact Dwarf Galaxy (BCD) through Mergers
Daya Nidhi Chhatkuli, Sanjaya Paudel, Rajesh Kumar Bachchan +2
It has long been speculated that Blue Compact Dwarf galaxies (BCDs) are formed through the interaction between low-mass gas-rich galaxies, but a few candidates of such systems have…
The formation of the brightest cluster galaxy and intracluster light in cosmological N-body simulations with the Galaxy Replacement Technique
Kyungwon Chun, Jihye Shin, Rory Smith +2
We investigate the formation channels of the intracluster light (ICL) and the brightest cluster galaxy (BCG) in clusters at . For this, we perform multi-resolution cosmologica…
Performance Assessment of the KASI-Deep Rolling Imaging Fast-optics Telescope pathfinder
Woowon Byun, Jongwan Ko, Yunjong Kim +14
In a CDM universe, most galaxies evolve by mergers and accretions, leaving faint and/or diffuse structures, such as tidal streams and stellar halos. Although these structures ar…
Spatial distribution of dark matter in and around galaxy clusters traced by galaxies, gas and intracluster stars in a simulated universe
Jihye Shin, Jong Chul Lee, Ho Seong Hwang +5
To understand how well galaxies, gas and intracluster stars trace dark matter in and around galaxy clusters, we use the IllustrisTNG cosmological hydrodynamical simulation and comp…
Comparison of spatial distributions of Intracluster light and Dark Matter
Jaewon Yoo, Jongwan Ko, Cristiano G. Sabiu +7
In a galaxy cluster, the relative spatial distributions of dark matter, member galaxies, gas, and intracluster light (ICL) may connote their mutual interactions over the cluster ev…
Is Abell 2261 a fossil galaxy cluster in a transitional dynamical state?
Hyowon Kim, Jongwan Ko, Rory Smith +5
Abell 2261 (A2661) is a well-studied fossil cluster, but previous studies give contradictory results on its dynamical states, such as its X-ray central entropy and magnitude gap. T…
