LAMOST Medium-Resolution Spectral Survey of Galactic Nebulae (LAMOST-MRS-N): Subtraction of Geocoronal Halpha Emission
Wei Zhang, Hong Wu, Chaojian Wu +10
We introduce a method of subtracting geocoronal Halpha emissions from the spectra of LAMOST medium-resolution spectral survey of Galactic nebulae (LAMOST-MRS-N). The flux ratios of…
VOLKS2: a transient search and localization pipeline for VLBI observations
Lei Liu, Zhijun Xu, Zhen Yan +3
We present VOLKS2, the second release of "VLBI Observation for transient Localization Keen Searcher". The pipeline aims at transient search in regular VLBI observations as well as…
VLBI data processing on coronal radio-sounding experiments of Mars express
Maoli Ma, Guifré Molera Calvés, Giuseppe Cimò +13
The ESA's Mars Express solar corona experiments were performed at two solar conjunctions in the years 2015 and 2017 by a number of radio telescopes in the European VLBI Network. Th…
Early-fusion Based Pulsar Identification with Smart Under-sampling
ShiChuan Zhang, XiangCong Kong, YueYing Zhou +5
The discovery of pulsars is of great significance in the field of physics and astronomy. As the astronomical equipment produces a large amount of pulsar data, an algorithm for auto…
Deformation measurement by single spherical near-field intensity measurement for large reflector antenna
Qian Ye, Boyang Wang, Qiang Yao +3
This paper presents a new method to obtain the deformation distribution on the main reflector of an antenna only by measuring the electric intensity on a spherical surface with the…
Artificial intelligence for celestial object census: the latest technology meets the oldest science
Baoqiang Lao, Tao An, Ailing Wang +5
Large surveys using modern telescopes are producing images that are increasing exponentially in size and quality. Identifying objects in the generated images by visual recognition…
