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…
Star Formation Properties in Barred Galaxies(SFB). III. Statistical Study of Bar-driven Secular Evolution using a sample of nearby barred spirals
Zhi-Min Zhou, Chen Cao, Hong Wu
Stellar bars are important internal drivers of secular evolution in disk galaxies. Using a sample of nearby spiral galaxies with weak and strong bars, we explore the relationships…
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…
Metallicity and Star Formation Activities of the Interacting System Arp 86 from Observation with MOS on Xinglong 2.16m Telescope
Zhi-Min Zhou, Hong Wu, Lei Huang +5
We present an analysis of the metallicity and star formation activities of HII regions in the interacting system Arp 86, based on the first scientific observation of the multi-obje…
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…
