Looking forward to working with a Solar telescope

 Aditi Bhatnagar found the move from India to RoCS - Rosseland Centre for Solar Physics to be swift. She has started her way to her Doctorate Degree.

Aditi completed her Master’s at the Indian Institute of Science Education and Research (IISER) Kolkata in July 2020.

- I was part of the 5 years Integrated BS-MS course at IISER Kolkata with a major in Physics.  My final year master’s project was in Solar Physics,  related to studying the observational properties of active regions on the solar surface and its relation to the solar cycle. During this project, I was exposed to various observational techniques and also learned to work with space-based data, which would be very useful for my Ph.D. work.  For my present project,  I am now learning to work with high-resolution ground-based observations for looking at small scale eruptions on the surface of the Sun like the Ellerman bombs.

- When did you start working at ITA? 

- I joined ITA on 1st October 2020 as a Doctoral Research Fellow. I am affiliated with RoCS and my supervisor is Professor Luc Rouppe Van der Voort. 

- What are you going to study?

- I am going to study the origin and impact of small-scale energetic phenomena in the solar atmosphere, mainly Ellerman Bombs in the quiet Sun (QSEBs). These have traditionally only been observed in active regions resulting from strong magnetic field interactions. The observation of these events in magnetically quiet regions is a relatively new discovery and many questions regarding their origin and impact on the solar atmosphere remain to be addressed.

- How do you plan to solve the main question?

- I plan to study the QSEBs using high-quality observations from ground-based and space-borne telescopes. One of the telescopes I will be using is the Swedish Solar telescope at La

Palma, Canary Islands. By combining these observations from the lower atmosphere with the (Interface Region Imaging Spectrograph) IRIS observations from the higher layers, we will get a more complete view of the impact of QSEBs on the solar atmosphere. The results of this work will further serve as valuable input for modelling efforts that are needed to achieve an understanding of their formation.

- What brought you to RoCS and Oslo? 

- The Solar Physics Research Group at Rosseland Centre for Solar Physics is well known for its expertise in computational modeling and observational methods related to space and plasma physics. So I applied to RoCS for the Ph.D. position as it will be a good starting point for my academic career. I was also fascinated by the natural beauty of Norway and its rich culture. Over the period of my stay, I really look forward to exploring this as much as possible.

- How can you describe your experience here so far?

- This was my first time out of India and I am glad it has been good so far. The process of moving in from India was really smooth because the UiO website was very informative about the steps to follow and the administrative staff at ITA was very helpful in coordinating and guiding me through all the formalities. The people here at ITA have been really helpful and friendly and I have found the formal and informal discussions around the office atmosphere very stimulating.

- What do you expect from this experience?

I think doing my Ph.D. from ITA will be a great start for my academic career. I hope I will be able to expand my knowledge and foster new collaborations that will be beneficial for my future as a research scholar. I also look forward to visits to the solar observatories and learning to work with the telescope first hand.
