Professor Somak Raychaudhury has taken over as the Director, IUCAA, with effect from September 1, 2015 on my superannuation. He had his undergraduate education at Presidency College, Kolkata and the University of Oxford. For his Ph.D. he worked with Professor Donald Lynden- Bell at the Institute of Astronomy, University of Cambridge, UK, followed by post- doctoral fellowships at the Harvard- Smithsonian Center for Astrophysics, Cambridge, Harvard University, USA, and at the Institute of Astronomy. He was a faculty member at IUCAA during 1995 - 2000, and then at the University of Birmingham.

He has had a very distinguished academic career, spanning his early work on cosmological singularities and various aspects of active galactic nuclei to more recent contributions to observational studies of galaxy evolution. From the early days of IUCAA, as Professor Jayant Narlikar and Professor Naresh Dadhich, and later Professor Varun Sahni and Professor T. Padmanabhan consolidated and led the research in relativity, and in theoretical astrophysics and cosmology, Professor Shyam Tandon in instrumentation and Professor Sanjeev Dhurandhar in the field of gravitational waves, it was Professor Kembhavi, who was largely responsible for building the observational programme at IUCAA. As the Dean of VAP, Professor Kembhavi's tireless efforts in widening the scope to IUCAA research, particularly in computational and observational computational facilities at IUCAA are the results of Professor Kembhavi's singular astrophysics to researchers at Indian contribution to the establishment and growth of IUCAA. universities, largely helped IUCAA establish Professor Kembhavi was one of the pioneers in the use of internet in India, leading itself as a premier institution of research in the establishment of network access to institutions of higher education in India, and the world, as well as succeed in its original later, facilitating the access to online library and journal facilities through INFONET. mandate to being a central facility for The establishment of IUCAA's regional centres also provided crucial support in connecting university faculty and students computational and library facilities to the universities in the various corners of the country. For to the international stage of astrophysics over a decade, he has led the worldwide Virtual Observatory initiative, making India a major research. The outstanding library and player in astronomical data mining, and in doing so, showed the way to effective partnerships with private enterprise, in particular the software industry. In the last few years, he has also led India's foray into the worldwide mega-projects, like the Thirty Metre Telescope (TMT) and LIGO-India, and made possible the partnerships with other major observatories like the SALT and LSST. Professor Kembhavi has always led from the front, and the network of astrophysics research in India, and IUCAA's place within it, would currently have been very inadequate without his efforts. It is a privilege, and a challenge for me to be given this opportunity to succeed him as the Director of this unique and illustrious institution.

College, Kottayam, conducted a three day workshop on Time IUCAA, and has always been a pillar of Domain Astronomy and Cosmology, during July 9 - 11, 2015, at C.M.S. College. The strength in the propagation and sustainment programme was intended to sensitize the participating post-graduate and young Ph.D. of astronomy research and education. students from the region on the latest trends in the area of the workshop. There were 35 The meeting was presided over by the Mar participants, who took part in all the activities of the workshop. Thoma Valiya Metropolitan, Rt. Rev. Philipose Mar Chrysostom, who was the On the first day morning, there was a special public meeting to express the warmth and manager of St. Thomas College when Ajit gratitude of the astronomy community in Kerala towards Ajit Kembhavi, who was Kembhavi first visited the institution to introduce IUCAA in 1996. Ninan Sajeeth Philip (St. Thomas College) welcomed the audience. V. C. Kuriakose (IRC, CUSAT, Kochi), S. K. Pandey (Vice-Chancellor, Pt.

University, Kottayam) felicitated and reminisced the services of Ajit Kembhavi. Joe Jacob gave the vote of thanks. Asha Kembhavi was also present at the meeting. A subsequent public lecture on New Astronomy by Ajit Kembhavi witnessed a large crowd comprising of students, teachers, and the public. KHAG L | IJmoc | No. 104 - OCTOBER 2015 | 03 The workshop sessions commenced in the afternoon with lectures by S.K. Pandey and H. P. Singh.

This was followed by a hands-on training session on Virtual Observatory Tools and its Applications to determine the various galaxy parameters by Sheelu Abraham (IUCAA) and Kaustubh Vaghmare (IUCAA). A special outreach programme for school students was also held on the second day of the workshop. On the third day, the lectures were led by Ranjan Gupta (IUCAA ), Sailo Mukherjee, and K. Indulekha. Selected two hundred students from neighbouring schools participated actively in the “A day with an Astronomer” programme, which was conducted by A.N. Ramaprakash, and Koshy George (IIA, Bangalore). This was followed by an interactive session in the afternoon, that was chaired by Ajit Kembhavi, in which the students asked questions on various aspects and the prospects in astronomy. P. Rajagopal, Head, Department of Physics, C.M.S. College was the local host, and Blesson George, Department of Physics, C.M.S. College was the local coordinator. KHAG L | IJmoc | No. 104 - OCTOBER 2015 | 04 REGIONAL MEETING ON TRENDS AND CHALLENGES IN ASTRONOMY AND ASTROPHYSICS The Department of Applied Mathematics, Calcutta University and IUCAA Resource Centre (IRC), Kolkata, jointly organized the regional meeting on Trends and Challenges in Astronomy and Astrophysics, during September 10 - 12, 2015. During the first two days, the venue was at the Department of Applied Mathematics, and on the last day, it was at the Department of Statistics, Calcutta University. Recently, there has been increasing interest for research in Astronomy and Astrophysics in the universities/colleges in the eastern part of India. Further, in view of the fact that several national level projects are being undertaken by different institutes including IUCAA, it is necessary to coordinate and consolidate the expertise available to meet The meeting was inaugurated by Swagata Sen and Sonali Chakravarti Banerjee, and Somak Raychaudhury lighting the the requirements of these mega national ceremonial lamp. projects.
