[Astronomy seminar] Astronomy departmental seminar this Friday Nov 25th - Henrik Eklund

[Astronomy seminar announcements]

Dear all,

The next SU astronomy departmental seminar will take place on Friday November 25th at 10:30 in room FC 61 (AlbaNova building, 6th floor) and on zoom.

Speaker: Henrik Eklund (SU)
Title:  Novel radio interferometric ALMA observations of the Sun

Abstract:

     In this talk I will present my work on observations of the Sun using radio interferometry with the Atacama Large Millimeter/sub-millimeter Array (ALMA), which offers novel high sensitivity and sub-arcsec angular resolution previously not possible in this wavelength regime. Observations at millimeter wavelengths facilitate the measurement of accurate temperatures, which is valuable towards understanding the complex physical processes taking place in the solar atmosphere. I will show the work that has been done to produce science-ready, high cadence datasets and some of their latest applications. These include identifying dynamic signatures and characterising small-scale features, developing the image reconstruction techniques to extract additional useful information from the data and using a spatio-temporal deep neural network to perform statistically based estimations and deconvolution of the data. In addition, we will look towards the future, where we at Stockholm University have the only accepted proposal for solar ALMA observations in 2022-2023 (cycle 9), which will provide the highest resolved observations at 3.0 mm to date.

We look forward to seeing many of you there. Thanks!

Eliot and Kris
