Statistics of precipitable water vapour above the sites of the 6-m Big Telescope Alt-azimuthal and new 3-m Large Solar Telescope using ERA5 data

Monthly notices of the Royal Astronomical Society, 2023
Atmospheric conditions have a major impact on the quality of ground-based astronomy observations. Among atmospheric molecular gases, water vapour presents a significant challenge in ground-based astronomical observations in spectral bands ranging from ...

New Insights into Type-I Solar Noise Storms from High Angular Resolution Spectroscopic Imaging with the Upgraded Giant Metrewave Radio Telescope

Astrophysical Journal
Type-I solar noise storms are perhaps the most commonly observed active radio emissions from the Sun at meter-wavelengths. Noise storms have a long-lived and wideband continuum background with superposed islands of much brighter narrowband and short ...

Reconstruction of Radio Images of the Sun Obtained by the Siberian Solar Radio Telescope

Radiophysics and Quantum Electronics, 2002
Reconstruction of radio images of the Sun obtained by the Siberian Solar Radio Telescope (SSRT) encounters two main problems. First, since the solar radio images at a wavelength of 5.2 cm have a high contrast, the amplitude–phase distribution in the antenna–feeder section should be known with a very high accuracy. Second, since such images comprise not

Detector Development for the Lunar Crater Radio Telescope

2022 IEEE Wireless Antenna and Microwave Symposium (WAMS), 2022
An ultra-long wavelength 3-30 MHz Lunar Crater Radio Telescope (LCRT) is under development at the NASA's Jet Propulsion Laboratory. The LCRT consists of a 1 km diameter reflector antenna and receiver to be deployed in the far side of the moon.

Building a Broad Band Solar Radio Telescope

2010
This is the most complex of the projects presented in this book. However it offers a lot of potential to learn about how receivers work, and as a useful radiometer or even spectrometer for solar flare observation.

Observing solar wind turbulence in the corona with ground-based radio telescopes

2021
<p>When point-like galactic and extragalactic radio sources are observed through the solar corona by ground-based radio telescopes, plasma density fluctuations in the turbulent solar wind scatter these photons, leading to an observed broadening and/or elongation of such sources.
