Radioastronomy

This page is dedicated to radioastronomy measurements and tests. Notes are mainly written in French. Some of them are translated into English.

My radio telescopes from 2012 to 2023

My main activities are measurements around the neutral hydrogen line (H1 or HI) at 21cm in our Galaxy and for other galaxies (M31-M33), the observation of OH lines in 18cm, the sun in low frequency continuum, solar eclipses, pulsar detection, interferometry, some presentations of popularization and associative life and finally the radio detection of meteor trails (RETRAM). My radio telescopes and observations are described in the documents below.

The transit was approximately at the +54° declination  (small circle UTC color coded).
