Seminars 07.01.2021 Utkarsh Giri on Exploring KSZ velocity reconstruction with N-body simulations and the halomodel. 21.01.2021 Rajesh Mondal on Probing the early Universe using cosmological 21-cm signal. 04.02.2021 Seema Satin on Stochastic fluctuations in strong gravity regions and compact stars: An approach towards studying statistical properties of dense matter in astrophysical objects and their dynamical properties. 18.02.2021 Sk Minhajur Rahaman on Non-resonant hydrodynamic Langmuir instability: The candidate for pulsar radio emissionmechanism. 18.03.2021 Barnali Das on Introducing main-sequence pulsars: An exotic subset of hot magnetic stars. | KHAG L | No. 126 - APRIL 2021 | 08 highlighted the recent developments in the field along with the basic required pedagogy. The topics covered included multi-messenger astronomy, stars and stellar evolution, galaxies and clusters of galaxies, and astronomical techniques. The resource persons were: Biman Nath (Raman Research Institute, Bengaluru), Biman Medhi (Gauhati University, Guwahati), and Somak Raychaudhury and Dhruba J. Saikia (both from IUCAA). The participants were introduced to stellarium, an open source planetarium for the computer, to explore the night sky, and a tutorial conducted on it by Prakash Arumugasamy (IUCAA). Two online quizzes were held as part of the course. There were about 40 participants from all over the country including several from the north-east. The course was coordinated by Gazi Ahmed and Rupjyoti Gogoi (both from Tezpur University) andDhruba J. Saikia. An interaction session of theARPIT 2020 participants with the resource persons was scheduled on each Sunday of March 2021 to ask questions, and discuss any material covered in the ARPIT course titled Stars and Stellar Systems. The participants of the Introductory Astronomy and Astrophysics Interactions with ARPIT 2020 Participants Colloquia 14.01.2021 Sowgat Muzahid on MUSEQuBES and MEGAFLOW: MUSE surveys on the circumgalactic medium. 28.01.2021 Roy Maartens on The cosmological surveys with the SKA. 11.02.2021 Pranjal Trive di on The hunt for axion dark matter. 25.02.2021 Anvar Shukurov on Morphology and topology of random fields: Application to compressible turbulence. 03.03.2021 Virander S. Chauhan on Vaccines, mutants and the way forward. 11.03.2021 Poonam Chandra on Environments of non- relativistic and relativistic explosions. 25.03.2021 Nikku Madhusudhan on Exoplanetary atmospheres. course were also invited to participate. These sessions produced interesting discussions on many of the topics covered in the course, and helped clear possible doubts. The images show two different sessions in progress.
