| KHAG L | No. 118 - APRIL 2019 | 12 Faculty members from half a dozen institutions participated in the Workshop on Radio Observations using HornAntenna at IUCAA, duringMarch 9 - 11, 2019. The goal of this workshop was to build a horn antenna and a complete system to detect the HI line of neutral atomic hydrogen at 1420.4 MHz coming from the Galactic plane, and understand the physics behind it. In this workshop, participants assembled all the mechanical parts to construct the horn antenna alongwith themount, and connected all the front-end electronics to detect the hydrogen line. Once the antenna was ready, it was pointed towards the Galactic plane, and the participants could see the spectrum on the screen. There was a shift in the 1420 MHz line compared to the rest Workshop on Radio Observations using Horn Antenna frequency due to the rotation of our Galaxy. This was done under the technical supervision of IUCAA Radio Physics Laboratory team, particularly Jameer Manur and Ashish Mhaske. The workshop was coordinated by Sayali Avachat, Joydeep Bagchi and Manojendu Choudhury (all from IUCAA), who were also resource persons. The Workshop on DevelopingAstronomy-Themed Experiments, which would help to get the subject into physics laboratories at under-graduate and post-graduate levels, was held at IUCAA, during June 18 - 20, 2018. There were about 50 astronomers and college/university teachers from various parts of the country, actively participating in the workshop, which discussed experiments on a number of themes at radio, optical and x-ray wavebands. The themes included: Properties of Electromagnetic Radiation, Optics in Astronomy / Te l e s c ope s , Hi gh Ene r gy and Gravitational Waves Astronomy, Positional Astronomy and Orbital Mechanics, Spectroscopy and Spectral A n a l y s i s , R a d i o A n t e n n a s , Interferometry, and Astronomical Da t a Ana l ys i s . Thi s workshop was coordinated by Samir Dhurde (IUCAA), Priya Hasan (Maulana Azad National Urdu University, Hyderabad), and Joe Jacob (Newman College, Thodupuzha) with several groups of astronomers including ASI-POEC members as resource persons.
