The Next Plan of the Nobeyama Radioheliograph [PDF]
International Astronomical Union Colloquium, 1994 A high time- and spatial-resolution radio interferometer for solar observations has been constructed at Nobeyama (Figure I.; Nakajima et al. 1994). The Nobeyama Radioheliograph consists of 84 antennas, 0.8m in diameter, arranged on a T-shape lines of 500m in the EW and 220m in the NS directions.

GPU-Based High-performance Imaging for Mingantu Spectral RadioHeliograph [PDF]
Publications of the Astronomical Society of the Pacific, 2017 As a dedicated solar radio interferometer, the MingantU SpEctral RadioHeliograph (MUSER) generates massive observational data in the frequency range of 400 MHz -- 15 GHz. High-performance imaging forms a significantly important aspect of MUSER's massive data processing requirements.

Identification of Super- and Sub-critical Regions in Shocks driven by Coronal Mass Ejections [PDF]
, 2011 In this work, we focus on the analysis of a CME-driven shock observed by SOHO/LASCO. We show that white-light coronagraphic images can be employed to estimate the compression ratio X = rho_d / rho_u all along the front of CME-driven shocks.

Comparison of solar radio and EUV synoptic limb charts during the present solar maximum [PDF]
, 2016 The present solar cycle is particular in many aspects: it had a delayed rising phase, it is the weakest of the last 100 years, and it presents two peaks separated by more than one year.
