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…
Swift Ultraviolet Observations of Supernova 2014J in M82: Large Extinction from Interstellar Dust
Peter J. Brown, Michael T. Smitka, Lifan Wang +8
We present optical and ultraviolet (UV) photometry and spectra of the very nearby and highly reddened supernova (SN) 2014J in M82 obtained with the Swift Ultra-Violet/Optical Teles…
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…
The nonlinear photon transfer curve of CCDs and its effects on photometry
Bin Ma, Zhaohui Shang, Lifan Wang +3
The photon transfer curve (PTC, variance vs. signal level) is a commonly used and effective tool in characterizing CCD performance. It is theoretically linear in the range where ph…
A new method of CCD dark current correction via extracting the dark information from scientific images
Bin Ma, Zhaohui Shang, Yi Hu +3
We have developed a new method to correct dark current at relatively high temperatures for Charge-Coupled Device (CCD) images when dark frames cannot be obtained on the telescope.…
Properties of extragalactic dust inferred from linear polarimetry of Type Ia Supernovae
F. Patat, S. Taubenberger, N. L. J. Cox +9
Aims: The aim of this paper is twofold: 1) to investigate the properties of extragalactic dust and compare them to what is seen in the Galaxy; 2) to address in an independent way t…
