Atmospheric turbulence reduces the image quality and resolution of ground-based optical telescopes. Future large solar telescopes (e.g. the CGST, China Giant Solar Telescope) should be equipped with adaptive optics (AO) systems. The design of AO syst

Four microwave bursts have been selected from the Nobeyama Radio Polarimeter (NoRP) observations with an extremely flat spectrum in the optically thin part and a very hard spectral index between 0 and −1 in the maximum phase of all bursts. It is fo

The Daocheng site is one of the three candidate sites for the Large Optical/infrared Telescope (LOT) of China. It was discovered by Yunnan Observatories during the survey of potential sites for the next-generation large-aperture solar telescopes of C

The Wumingshan mountain (Mt. WMS), located in the Grand Shangri-La area of south-west China, has been selected as one of the most potential regions for hosting China’s next-generation ground-based large telescopes. Firstly, Mt. WMS has ideal astron

It is first proposed a theoretical scaling law respectively for the coronal magnetic field strength $B$ and electron power-law index $\delta$ versus frequency and coronal height in solar microwave burst sources. Based on the non-thermal gyro-synchrot

Excellent sites are necessary for developing and installing ground-based large telescopes. For very-high-resolution solar observations, it had been unclear whether there exist good candidate sites in the west areas in China, including the Tibetan Pla

Based on the frequency dependence of the power-law distribution of the peak fluxes in 486 radio bursts in 1-35 GHz observed by Nobeyama Radio Polarimeters (see Song et al. in Astrophys. J. 750:160, 2012), we have first suggested in this paper that th

With the aim of studying the relationship between the relative motions of the loop-top (LT) source and footpoints (FPs) during the rising phase of solar flares, we give a detailed analysis of the X7.1 class flare that occurred on 2005 January 20. The

Based on Dulk and Marsh's approximate theory about nonthermal gyrosynchrotron radiation, one simple impulsive microwave burst with a loop-like structure is selected for radio diagnostics of the coronal magnetic field and column density of nonthermal
