Hearty congratulations to Mr. Rajashik Tarafder

Mr. Rajashik Tarafder, a DPS student, who did his MS Thesis research at CESSI, has received the best paper award at a national level undergraduate physics symposium entitled “Presision 2017” which was organized by Presidency University. The basis of his award was a presentation on one of his MS research projects on “A Mathematical Model of Global Climate with Solar and Anthropogenic Forcing.”

Hearty congratulations to Mr. Rajashik Tarafder.

Transient Weakening of Earth’s Magnetic Shield

A group of international scientists (including CESSI faculty named Prasad Subramanian) has observed a 'Transient Weakening of Earth’s Magnetic Shield.' This observation was conducted by recording the levels of Galactic Cosmic Ray particles using GRAPES-3 muon telescope. The study is instrumental in understanding the impact of future solar storms on our technological infrastructure.

Promote Science at CESSI

Graduate students at CESSI have started a new initiative called Promote Science which aims to disseminate science to the masses.

Congratulations to Mayukh Panja.

Mayukh Panja, a Masters student at CESSI successfully competed his Masters Degree with a Thesis on "A Magnetofrictional Model to study the Solar Corona". He has secured a PhD position at the Max Planck Institute for Solar System Research in Gottingen, Germany. We congratulate Mayukh and wish him all the best for his PhD research.

Congratulations to Soumitra Hazra.

Soumitra Hazra, a PhD student of DPS who worked at CESSI under the supervision of Dibyendu Nandi successfully defended his PhD Thesis on "Exploring the Origin and Dynamics of Solar Magnetic Fields" and has secured a Research Scientist position at the Department of Physics and Astronomy of Georgia State University (Atlanta, USA). We congratulate Soumitra and wish him all the best in his future endeavours.

Rajashik Tarafder was invited to the Lindau Nobel Laureate Meeting 2016

Rajashik Tarafder, a BS-MS student was invited to the Lindau Nobel Laureate Meeting 2016 as a young scientist.This meet involved 400 young scientists from across the world interacting with 29 Nobel Laureates over a 6 day period.

His reflections on the meet:

Hearty congratulations to Dr. Nayak and Ms. Samajdar.

It is a pleasure to share with you that the 2016 Gruber Foundation Cosmology Prize recognizes Ronald Drever, Kip Thorne, Rainer Weiss, and the entire Laser Interferometer Gravitational-Wave Observatory (LIGO) discovery team for the first observation of gravitational waves. As you are aware, Dr. Rajesh Kumble Nayak and Ms. Anuradha Samajdar are part of the LIGO team from IISER Kolkata. For more details, please see the following link:

Detection of Gravitational Waves

CESSI and Physics personnel have been part of a global team that has finally detected astrophysical gravitational waves 100 years after their existence was predicted by Albert Einstein. Gravitational astrophysics (and the hunt for gravitational waves) is one of the research aims of CESSI and this detection opens up a new window for probing exotic objects and extreme phenomena in the Universe.

We proudly note the involvement of Dr. Rajesh Nayak and his PhD student Ms. Anuradha Samajdar in this global effort and congratulate them and the international LIGO team for this outstanding breakthrough

Science for Space Weather Conference

CESSI was the primary Indian organizer for the Science for Space Weather Workshop which was held in Goa, India from 24-29th January, 2016. A total of 104 scientists and students from 21 countries participated in this workshop which was co-sponsored by CESSI-IISER Kolkata, University of Kiel, Physical Research Laboratory, Committee on Space Research, Scientific Committee on Solar-Terrestrial Physics, NASA International Living with a Star Program and ISRO. During this workshop a special school on space weather was organized by NASA/NSFs Community Coordinated Modelling Center (CCMC) and CESSI for students. In the school 22 PhD/MS students from India and 3 students from abroad participated. The workshop and school were very successful; highlights of which were unveiling of plans for India's first solar space mission, and the emergence of a consensus document calling for international cooperation in sharing of resources amongst space agencies to support space weather data analysis and research.

More information on the workshop and school are available at:

Mr. Rakesh Mazumder, PhD student of CESSI, was selected for the prestigious Sokendai Asian Solar Physics Winter School and attended the same in Japan from 26-28th January 2016. His trip to Japan to attend this school was completely sponsored by the organizers.

Dr. Aveek Sarkar, who worked as a Postdoctoral Research Associate and subsequently Research Scientist at CESSI for two and half years, was offered a faculty position at the Physical Research Laboratory (PRL, Ahmedabad), the premier research institute of the Department of Space. He joined PRL as a Reader on 15th December, 2015. We wish him all the best in his future endeavours.

MAST Facility Commissioned

We congratulate CESSI Affiliate and Co-I, Dr. Nandita Srivastava for her efforts in the successful commissioning of the Multi-Aperture Solar Telescope (MAST) Facility at Udaipur Solar Observatory. MAST is India's most advanced solar observatory. For further details see:
