A 0.03 Hz Radio Quasi-periodic Oscillation During the 2025 Flare of GRS 1915+105
Ya Xing Li, Lei Liu, Wu Jiang +3
Our weekly-cadence radio monitoring campaign captured a bright flare in 2025 from the microquasar GRS 1915+105, observed simultaneously in the S- and X-bands (2.25 GHz and 8.42 GHz…
Lunar Orbital VLBI Experiment: motivation, scientific purposes and status
Xiaoyu Hong, Weiren Wu, Qinghui Liu +47
The Lunar Orbital VLBI Experiment (LOVEX) is a scientific component of the Chinese Lunar Exploration Project (CLEP) Chang'E-7. The spaceborne component of LOVEX is implemented onbo…
Orbital configurations of spaceborne interferometers for studying photon rings of supermassive black holes
Ben Hudson, Leonid I. Gurvits, Maciek Wielgus +3
Recent advances in technology coupled with the progress of observational radio astronomy methods resulted in achieving a major milestone of astrophysics - a direct image of the sha…
OmniUV: A Multi-Purpose Simulation Toolkit for VLBI Observation
Lei Liu, Weimin Zheng, Jian Fu +1
We present OmniUV, a multi-purpose simulation toolkit for space and ground VLBI observations. It supports various kinds of VLBI stations, including Earth (ground) fixed, Earth orbi…
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…
The optimization of satellite orbit for Space-VLBI observation
Lei Liu, Weimin Zheng
By sending one or more telescopes into space, Space-VLBI (SVLBI) is able to achieve even higher angular resolution and is therefore the trend of the VLBI technique. For SVLBI progr…
Space very long baseline interferometry in China
Tao An, Xiaoyu Hong, Weimin Zheng +19
Space very long baseline interferometry (VLBI) has unique applications in high-resolution imaging of fine structure of astronomical objects and high-precision astrometry due to the…
The localization of single pulse in VLBI observation
Lei Liu, Wu Jiang, Weimin Zheng +4
In our previous work, we propose a cross spectrum based method to extract single pulse signals from RFI contaminated data, which is originated from geodetic VLBI postprocessing. Th…
Fast Radio Burst Search: Cross Spectrum vs. Auto Spectrum Method
Lei Liu, Weimin Zheng, Zhen Yan +1
The search of fast radio burst (FRB) is a hot topic in current radio astronomy study. In this work, we carry out single pulse search for a VLBI pulsar observation data set using bo…
A Fast Radio Burst Search Method for VLBI Observation
Lei Liu, Fengxian Tong, Weimin Zheng +2
We introduce the cross spectrum based FRB (Fast Radio Burst) search method for VLBI observation. This method optimizes the fringe fitting scheme in geodetic VLBI data post processi…
