The Anisotropic Two-Point Correlation Functions of the Nonlinear Traceless Tidal Field in the Principal-Axis Frame
Jounghun Lee, Oliver Hahn, Cristiano Porciani
Galaxies on the largest scales of the Universe are observed to be embedded in the filamentary cosmic web which is shaped by the nonlinear tidal field. As an efficient tool to quant…
An Ultraviolet Study of Star-Forming Regions in M31
Yongbeom Kang, Luciana Bianchi, Soo-Chang Rey
We present a comprehensive study of star-forming (SF) regions in the nearest large spiral galaxy M31. We use GALEX far-UV (1344-1786 Å, FUV) and near-UV (1771-2831 Å, NUV) imaging…
Ages of M33 Star Clusters Based on the HST/WFPC2 Photometry
Won-Kee Park, Hong Soo Park, Myung Gyoon Lee
We present a result of age estimation for star clusters in M33. We obtain color-magnitude diagrams (CMDs) of resolved stars in 242 star clusters from the HST/WFPC2 images. We estim…
Probing the Warm Dark Matter with High-z Quasar Luminosity Function
Hyunmi Song, Jounghun Lee
In a warm dark matter (WDM) cosmology, the first objects to form at z>=20 are one dimensional filaments with mean length on the order of the WDM free-streaming scale. Gao and Theun…
