  • Characterising coronal turbulence using snapshot imaging of radio bursts in 80–200 MHz 
    Mohan, Atul (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Context. Metrewave solar type-III radio bursts offer a unique means to study the properties of turbulence across coronal heights. Theoretical models have shown that the apparent intensity and size of the burst sources ...
  • EMISSA (Exploring Millimeter Indicators of Solar-Stellar Activity) II. Towards a robust indicator of stellar activity 
    Mohan, Atul; Wedemeyer, Sven; Hauschildt, Peter, H.; Pandit, Sneha; Saberi, Maryam (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Context: An activity indicator, which can provide a robust quantitative mapping between the stellar activity and the physical properties of its atmosphere, is important in exploring the evolution of the observed active ...
  • EMISSA (Exploring Millimeter Indicators of Solar-Stellar Activity): I. The initial millimeter–centimeter main-sequence star sample 
    Mohan, Atul; Wedemeyer, Sven; Pandit, Sneha; Saberi, Maryam; Hauschildt, Peter H. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Context. Due to their wide wavelength coverage across the millimeter to centimeter (mm–cm) range and their increased sensitivity, modern interferometric arrays facilitate observations of the thermal and non-thermal radiation ...
  • Energetic particle activity in AD Leo: Detection of a solar-like type-IV burst 
    Mohan, Atul; Mondal, Surajit; Wedemeyer, Sven; Gopalswamy, Natchimuthuk (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Context. AD Leo is a young and active M dwarf with high flaring rates across the X-ray-to-radio bands. Flares accelerate particles in the outer coronal layers and often impact exo-space weather. Wide-band radio dynamic ...
  • Preparing for solar and heliospheric science with the SKAO: An Indian perspective 
    Oberoi, Divya; Bisoi, Susanta Kumar; Raja, K. Sasikumar; Kansabanik, Devojyoti; Mohan, Atul; Mondal, Surajit; Sharma, Rohit (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    The Square Kilometre Array Observatory (SKAO) is perhaps the most ambitious radio telescope envisaged yet. It will enable unprecedented studies of the Sun, corona and heliosphere and help to answer many of the outstanding ...
  • The Solar ALMA Science Archive (SALSA): First release, SALAT, and FITS header standard 
    de Jorge Henriques, Vasco Manuel; Jafarzadeh, Shahin; Guevara Gomez, Juan Camilo; Eklund, Henrik; Wedemeyer, Sven; Szydlarski, Mikolaj; Haugan, Stein Vidar Hagfors; Mohan, Atul (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    In December 2016, the Atacama Large Millimeter/submillimeter Array (ALMA) carried out the first regular observations of the Sun. These early observations and the reduction of the respective data posed a challenge due to ...
