Seven broad absorption line quasars with excess broad band absorption near 2250 Å
Shaohua Zhang, Jian Ge, Peng Jiang +6
We report the discovery of excess broad band absorption near 2250 A (EBBA) in the spectra of seven broad absorption line (BAL) quasars. By comparing with the statistical results fr…
Unshifted Metastable He I* Mini-Broad Absorption Line System in the Narrow Line Type 1 Quasar SDSS J080248.18551328.9
Tuo Ji, Hongyan Zhou, Peng Jiang +11
We report the identification of an unusual absorption line system in the quasar SDSS J080248.18551328.9 and present a detailed study of the system, incorporating follow-up optic…
An Unobscured type II quasar candidate: SDSS J012032.19-005501.9
Y. Li, W. Yuan, H. Y. Zhou +4
We report the finding of an unobscured type II Active Galactic Nuclei (AGN) candidate, SDSS J012032.19-005501.9 at a relatively high redshift of 0.601,which shows a number of unusu…
Photometric Redshifts in the Hawaii-Hubble Deep Field-North (H-HDF-N)
G. Yang, Y. Q. Xue, B. Luo +11
We derive photometric redshifts (\zp) for sources in the entire ( deg) Hawaii-Hubble Deep Field-North (\hdfn) field with the EAzY code, based on point spread function-…
Difference Image Analysis of Defocused Observations with CSTAR
Ryan J. Oelkers, Lucas M. Macri, Lifan Wang +13
The Chinese Small Telescope ARray (CSTAR) carried out high-cadence time-series observations of 27 square degrees centered on the South Celestial Pole during the Antarctic winter se…
Meteorological data for the astronomical site at Dome A, Antarctica
Yi Hu, Zhaohui Shang, Michael C. B. Ashley +7
We present an analysis of the meteorological data collected at Dome A, Antarctica by the Kunlun Automated Weather Station, including temperatures and wind speeds at eight elevation…
Outflow and hot dust emission in broad absorption line quasars
Shaohua Zhang, Huiyuan Wang, Tinggui Wang +4
We have investigated a sample of 2099 broad absorption line (BAL) quasars with z=1.7-2.2 built from the Sloan Digital Sky Survey Data Release Seven and the Wide-field Infrared Surv…
Planetary Transit Candidates in the CSTAR Field: Analysis of the 2008 Data
Songhu Wang, Hui Zhang, Ji-Lin Zhou +26
The Chinese Small Telescope ARray (CSTAR) is a group of four identical, fully automated, static 14.5 cm telescopes. CSTAR is located at Dome A, Antarctica and covers 20 square degr…
Chandra and MMT observations of low-mass black hole active galactic nuclei accreting at low rates in dwarf galaxies
W. Yuan, H. Zhou, L. Dou +3
We report on Chandra X-ray observations of four candidate low-mass black hole (<10^6Msun) active galactic nuclei (AGNs) that have the estimated Eddington ratios among the lowest (~…
