Exploring radio emissions from confirmed exoplanets using SKA

Frontiers in Astronomy and Space Sciences
Our understanding of magnetic fields in exoplanets remains limited compared to those within our solar system. Planets with magnetic fields emit radio signals primarily due to the Electron Cyclotron Maser Instability mechanism.

Search for molecular bremsstrahlung radiation signals in Ku band with coincidental operations of radio telescopes with air shower detectors

EPJ Web of Conferences, 2013
Microwave radiation from extensive air showers is expected to provide a new technique to observe UHECR. We insatlled and operate radio telescopes in Osaka and at Telescope Array site in Utah, USA.

FIRST "Winged" and X-shaped Radio Source Candidates: II. New Redshifts

, 2008
We report optical spectroscopic observations of X-shaped radio sources with the Hobby-Eberly Telescope and Multiple-Mirror Telescope, focused on the sample of candidates from the FIRST survey presented in Paper I (Cheung 2007).

Timing Offset Calibration of CZTI instrument aboard ASTROSAT

, 2018
The radio as well as the high energy emission mechanism in pulsars is yet not understood properly. A multi-wavelength study is likely to help in better understanding of such processes.

Space Debris Detection in Low Earth Orbit with the Sardinia Radio Telescope

, 2017
Space debris are orbiting objects that represent a major threat for space operations. The most used countermeasure to face this threat is, by far, collision avoidance, namely the set of maneuvers that allow to avoid a collision with the space debris ...
