Star Formation Histories of Dwarf Lenticular Galaxies

Hong Bae Ann, Mira Seo

Star formation histories (SFHs) are essential for understanding galaxy formation and evolution. We present the mean SFHs of 148 dwarf lenticular galaxies (dS0s) derived from the Sl…

Star Formation Histories of Dwarf Spheroidal and Dwarf Elliptical Galaxies in the Local Universe

Mira Seo, H. B. Ann

We present the star formation histories (SFHs) of early-type dwarf galaxies, dSphs and dEs, in the local universe within z=0.01. The SFHs of early-type dwarf galaxies are character…

Luminosity Distribution of Dwarf Elliptical-like Galaxies

Mira Seo, Hong Bae Ann

We present the structural parameters of dwarf elliptical-like galaxies in the local universe () derived from the band images of the Sloan Digital Sky S…

Properties of Fast and Slow Bars Classified by Epicyclic Frequency Curves from Photometry of Barred Galaxies

Yun Hee Lee, Myeong-Gu Park, Ho Seong Hwang +3

We test the idea that bar pattern speeds decrease with time owing to angular momentum exchange with a dark matter halo. If this process actually occurs, then the locations of the c…

Cosmic Evolution of Barred Galaxies up to z ~ 0.84

Taehyun Kim, E. Athanassoula, Kartik Sheth +4

We explore the cosmic evolution of the bar length, strength, and light deficit around the bar for 379 barred galaxies at 0.2 < z 0.835 using F814W images from the COSMOS sur…

Bar Classification based on the Potential Map

Yun Hee Lee, Myeong-Gu Park, Hong Bae Ann +2

We introduce a new approach to classify barred galaxies that utilizes the transverse-to-radial force ratio map (ratio map, hereafter) in a different manner from previous studies. W…
