The THU-NAOC Transient Survey: the Performance and the First-year Result
Tianmeng Zhang, Xiaofeng Wang, Junchen Chen +18
The Tsinghua University-National Astronomical Observatories of China (NAOC) Transient Survey (TNTS) is an automatic survey for a systematic exploration of optical transients (OTs),…
Spectral Energy Distributions and Masses of 304 M31 Old Star Clusters
Jun Ma, Song Wang, Zhenyu Wu +8
This paper presents CCD multicolor photometry for 304 old star clusters in the nearby spiral galaxy M31. Of which photometry of 55 star clusters is first obtained. The observations…
Optical and Ultraviolet Observations of A Low-Velocity Type II-Plateau Supernova 2013am in M65
Jujia Zhang, Xiaofeng Wang, Paolo A. Mazzali +16
Optical and ultraviolet observations for the nearby type II-plateau supernova (SN IIP) 2013am in the nearby spiral galaxy M65 are presented in this paper. The early spectra are cha…
The 0.1<z<1.65 evolution of the bright end of the [OII] luminosity function
Johan Comparat, Johan Richard, Jean-Paul Kneib +33
We present the [OII] luminosity function measured in the redshift range 0.1<z<1.65 with unprecedented depth and accuracy. Our measurements are based on medium resolution flux-calib…
Optical and Ultraviolet Observations of the Narrow-Lined Type Ia SN 2012fr in NGC 1365
JuJia Zhang, XiaoFeng Wang, JinMing Bai +5
Extensive optical and ultraviolet (UV) observations of the type Ia supernova (SN Ia) 2012fr are presented in this paper. It has a relatively high luminosity, with an absolute -b…
Estimation of Absolute Magnitude-dependent Galactic Model Parameters In Intermediate Latitude With SDSS and SCUSS
Yunpeng Jia, Cuihua Du, Zhenyu Wu +15
Based on SDSS and South Galactic Cap of u-band Sky Survey (SCUSS) early data, we use star counts method to estimate the Galactic structure parameters in an intermediate latitude wi…
