Research Developments in Li-Paczyński Novae (II): Observational Aspect

Wang, Shan-qin; Dai, Zi-gao; Wu, Xue-feng

Since the LP-Nova models were proposed, and the short gamma-ray burst (SGRB) afterglows were confirmed, people have actively made searches for the evidence of the existence of LP-Novae among the optical (or near-infrared) counterparts of SGRBs. In this paper, we first summarize these observational progresses before 2012 in Section 2. In Section 3 …

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

Kong, Xu; Fang, Guan-wen; Ma, Zhong-yang

Utilizing the multi-band photometric data 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 images in the CANDELS (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey) field,…

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

Kong, Xu; Chen, Yang; Fang, Guan-Wen +1 more

Using the high-resolution F160W images observed by the HST WFC3 (Hubble Space Telescope Wide Field Camera 3) in the CANDELS-EGS (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey-Extended Groth Strip) field, we have studied the morphological and structural features of 9 ultraluminous infrared galaxies (ULIRGs) at z ∼ 2. We find a wide…

A Research on the Evolution of Star Formation Activities of Early-type Galaxies

Zheng, Xian-Zhong; Wang, Fang

The observational investigation of the evolution of the star formation activities of early-type galaxies (ETGs) with redshifts helps us to understand the formation and evolution of this kind of galaxies. Combined with the highresolution images from HST/ACS (Hubble Space Telescope/Advanded Camera for Surveys) of the GEMS (Galaxy Evolution fromMorph…
