(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Abstract The Interface Region Imaging Spectrograph (IRIS) has been obtaining near- and far-ultraviolet images and spectra of the solar atmosphere since July 2013. IRIS is the highest resolution observatory to provide ...
  • A Statistical Study of IRIS Observational Signatures of Nanoflares and Nonthermal Particles 
    Cho, Kyuhyoun; Testa, Paola; De Pontieu, Bart Walter; Polito, Vanessa (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Nanoflares are regarded as one of the major mechanisms of magnetic energy release and coronal heating in the solar outer atmosphere. We conduct a statistical study on the response of the chromosphere and ...
