Morphological Classification of High-redshift Massive Galaxies in the COSMOS/UltraVISTA Field

Kong, X.; Fang, G. W.; Ma, Z. Y.

Utilizing the multi-band photometry catalog of the COSMOS (Cosmic Evolution Survey)/UltraVISTA (Ultra-deep Visible and Infrared Survey Telescope for Astronomy) field and the high-resolution HST WFC3 (Hubble Space Telescope Wide Field Camera 3) near-infrared imaging from the CANDELS (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey) f…

Morphology and Structure of Ultraluminous Infrared Galaxies at z ≈ 2 in the EGS Field

Chen, Y.; Kong, X.; Fang, G. W. +1 more

Using high-resolution HST WFC3 (Hubble Space Telescope Wide Field Camera 3) F160W imaging from the CANDELS-EGS (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey-Extended Groth Strip) field, we present the morphology analysis of 9 ultraluminous infrared galaxies (ULIRGs) at z≈2. We find a wide range of morphological diversities for th…

The Evolution of Star Formation in Early-type Galaxies

Zheng, X. Z.; Wang, F.

How the star formation activity in early-type galaxies (ETGs) evolves over cosmic time provides observational constraints on the picture of the formation and evolution of ETGs. Using HST/ACS (Hubble Space Telescope/Advanced Camera for Surveys) imaging data from the GEMS (Galaxy Evolution from Morphology and SEDs) survey and multi-band data in the …
