  • ALMA observations of transient heating in a solar active region 
    da Silva Santos, João Manuel; de la Cruz Rodriguez, Jaime; White, S. M.; Leenaarts, Jorrit; Vissers, Gregal Joan Maria; Hansteen, Viggo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Aims. We aim to investigate the temperature enhancements and formation heights of solar active-region brightenings such as Ellerman bombs (EBs), ultraviolet bursts (UVBs), and flaring active-region fibrils (FAFs) using ...
  • The multi-thermal chromosphere: Inversions of ALMA and IRIS data 
    da Silva Santos, João Manuel; de la Cruz Rodriguez, Jaime; Leenaarts, Jorrit; Chintzoglou, Georgios; De Pontieu, Bart Walter; Wedemeyer, Sven; Szydlarski, Mikolaj Marcin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Context. Numerical simulations of the solar chromosphere predict a diverse thermal structure with both hot and cool regions. Observations of plage regions in particular typically feature broader and brighter chromospheric ...
