An Investigation of Collisions between Fiber Positioning Units in LAMOST
Xiao-Jie Liu, Gang Wang
The arrangement of the fiber positioning units in LAMOST focal plane may lead to the collisions during the fiber allocation. To avoid these collisions, the soft protection system h…
Focal plane wave-front sensing algorithm for high-contrast imaging
JiangPei Dou, DeQing Ren, YongTian Zhu +1
High-contrast imaging provided by a coronagraph is critical for the direction imaging of the Earth-like planet orbiting its bright parent star. A major limitation for such direct i…
18-Months Operation of Lunar-based Ultraviolet Telescope: A Highly Stable Photometric Performance
J. Wang, X. M. Meng, X. H. Han +7
We here report the photometric performance of Lunar-based Ultraviolet telescope (LUT), the first robotic telescope working on the Moon, for its 18-months operation. In total, 17 IU…
Performance analysis of parallel gravitational -body codes on large GPU cluster
Siyi Huang, Rainer Spurzem, Peter Berczik
We compare the performance of two very different parallel gravitational -body codes for astrophysical simulations on large GPU clusters, both pioneer in their own fields as well…
Block Time Step Storage Scheme for Astrophysical N-body Simulations
Maxwell Xu Cai, Yohai Meiron, M. B. N. Kouwenhoven +2
Astrophysical research in recent decades has made significant progress thanks to the availability of various -body simulation techniques. With the rapid development of high-perf…
A Practical Deconvolution Computation Algorithm to Extract 1D Spectra from 2D Images of Optical Fiber Spectroscopy
Guangwei Li, Haotong Zhang, Zhongrui Bai
Bolton and Schlegel presented a promising deconvolution method to extract 1D spectra from a 2D optical fiber spectral CCD image. The method could eliminate the PSF difference betwe…
NBODY6++GPU: Ready for the gravitational million-body problem
Long Wang, Rainer Spurzem, Sverre Aarseth +4
Accurate direct -body simulations help to obtain detailed information about the dynamical evolution of star clusters. They also enable comparisons with analytical models and Fok…
Optical Turbulence Characterization at LAMOST Site: Observations and Models
L. -Y. Liu, C. Giordano, Y. -Q. Yao +5
Atmospheric optical turbulence seriously limits the performance of high angular resolution instruments. An 8-night campaign of measurements was carried out at the LAMOST site in 20…
Data Processing Pipeline for Pointing Observations of Lunar-based Ultraviolet Telescope
Xian-Min Meng, Li Cao, Yu-Lei Qiu +7
We describe the data processing pipeline developed to reduce the pointing observation data of Lunar-based Ultraviolet Telescope (LUT), which belongs to the Chang'e-3 mission of the…
Antenna system characteristic and solar radio burst observation
Sha Li, Yihua Yan, Zhijun Chen +2
Chinese Spectral Radio Heliograph (CSRH) is an advanced aperture synthesis solar radio heliograph, developed by National Astronomical Observatories, Chinese Academy of Sciences ind…
Comb-calibrated solar spectroscopy through a multiplexed single-mode fiber channel
R A Probst, L Wang, H-P Doerr +7
We investigate a new scheme for astronomical spectrograph calibration using the laser frequency comb at the Solar Vacuum Tower Telescope on Tenerife. Our concept is based upon a si…
An Investigation of the Absolute Proper Motions of the SCUSS Catalog
Xiyan Peng, Zhaoxiang Qi, Zhenyu Wu +21
Absolute proper motions for 7.7 million objects were derived based on data from the South Galactic Cap u-band Sky Survey (SCUSS) and astrometric data derived from uncompress…
A Calibration of NICMOS Camera 2 for Low Count-Rates
D. Rubin, G. Aldering, R. Amanullah +20
NICMOS 2 observations are crucial for constraining distances to most of the existing sample of z > 1 SNe Ia. Unlike the conventional calibration programs, these observations involv…
The Eleventh and Twelfth Data Releases of the Sloan Digital Sky Survey: Final Data from SDSS-III
Shadab Alam, Franco D. Albareti, Carlos Allende Prieto +271
The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fib…
