| KHAG L | No. 128 - OCTOBER 2021 | 09 Astronomy-themed IUCAA ACE Repository of Experiments has been initiated, hosted by the IUCAA Library. The repository is divided into five categories, three of these are based on the wavelengths of observations in the electromagnetic spectrum, the fourth one is on gravitational waves, and the fifth one is of a more general nature. These are categorized as (i) radio, (ii) infrared, optical and ultraviolet, (iii) high-energy astrophysics, which includes X-rays and gamma-rays, (iv) gravitational waves, and (v) others. The link to the Repository is: http://repository.iucaa.in: 8080/jspui/handle/11007/4545 IUCAAACE Repository of Experiments The repository has been started with a few radio astronomy related experiments, which could be done at home. Thesewere part of the experiments offered during the Radio Astronomy Winter School – 2020, and IUCAA Refresher Course on Astronomy and Astrophysics – 2021. Members of the community are encouraged to contribute to the Repository. Those wishing to do so are requested to email us at nrciucaa@gmail.com The playlists of IUCAAACE Courses which have been made available so far after reviewing and editing are listed below. The courses are either pedagogical or highlight recent developments and emphasize emerging areas in the respective areas, while touching upon the basic required pedagogy. The respective sites have been given just below each course. (I) Astronomy andAstrophysics This course, consisting of 57 videos spread across 11 modules, gives an overviewof the field andwas designed as part of ARPIT2018-19. These video presentations were made by 27 resource persons from 11 institutions of higher education and research spread across the country. https://www.youtube.com/playlist?list=PLQAvibmFRM 2_Qd5cljyKphpIlTrWuBwnA (ii) Stars andStellar Systems The course focuses on different aspects of stars and stellar systems starting from the basics. It was designed as part of ARPIT2019-20, and the presentations were made by 13 resource persons from 8 institutions of higher education and research spread across the country. https://www.youtube.com/playlist?list=PL3jLiVc5sr3NT NRpRLVRTEv6xAS2axAq3 (iii) Introduction toOptical and Infrared Interferometry This course consisting of 20 videos, which discusses the basics of interferometry at optical and infrared wavelengths and its applications. The course was delivered in 2020 by Jean Surdej (Honorary Director, IUCAA ACE Courses Extragalactic Astrophysics and Space Observatories Group, University of Liege, Belgium). https://www.youtube.com/playlist?list=PL3jLiVc5sr3PH iVkE_uCq_wS0LLZnVkph (iv) Fourier Transforms This short course consisting of 4 videos was presented in 2020 byAvinashDeshpande (IUCAA). (v) RadioAstronomyWinter School – 2020 The presentations on different aspects of radio astronomy as well as the experiments, which were designed to be carried out at the residence of participants due to the ongoing pandemic are available in this playlist. There are 36 videos in all presented by faculty and staff from both IUCAAandNCRA-TIFR, Pune. (vi) AdvancedCourse onPulsar Astrophysics This course gives a broad and intensive look at the fundamental questions and results of pulsar astrophysics. The set of 20 lectures accompanied by assignments and quizzes was delivered in 2021 by Dipankar Bhattacharya (IUCAA). https://www.youtube.com/playlist?list=PL3jLiVc5sr3Pq qG_DsiDGHt82nmBg-Isa https://www.youtube.com/playlist?list=PL3jLiVc5sr3NY 5BT8ewquHnbCeSath3L4 https://www.youtube.com/watch?v=v_wzCQuRpSM&li st=PL3jLiVc5sr3MrtRHwaGIWVRlRGa_JIdWI
