Special Seminars with External Speakers


2019 July 5, Surajit Mondal, National Centre for Radio Astrophysics (NCRA), Pune, India: Investigating the two extremes of solar activity using data from the Murchison Widefield Array


The solar activity is of two types: one when the sun is very active and gives rise to many flares and coronal mass ejections (CMEs) and other when the sun is very quiet and there is no X-ray flare for several days. Using data from the MWA, we have investigated a CME event and a quiet sun. We have been able to detect gyro-synchrotron emission from the CME and have successfully modelled the emission. Using the model, we have estimated different plasma parameters in a spatially resolved manner at different times. In this talk, I will discuss the details of the fitting procedure and how we succeeded in detecting the emission even after 2 hours after the initial eruption and at a height of ~4.7 solar radius. In the second part of my talk, I will focus on the coronal heating problem. I will give the first direct and robust observational evidence, to the best of our knowledge, that Hudson’s criterion is satisfied even in the case of quiet sun. Several other predictions of the nanoflare hypothesis are also found to be valid in this case. All these works have been possible with the automated high dynamic range imaging routine we have developed. I will also talk about this briefly. If time permits I will also briefly discuss the various other works which are happening in our group.
