  • Jess, David B.; Jafarzadeh, Shahin; Keys, Peter H.; Stangalini, Marco; Verth, Gary; Grant, Samuel D. T. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Waves and oscillations have been observed in the Sun’s atmosphere for over half a century. While such phenomena have readily been observed across the entire electromagnetic spectrum, spanning radio to gamma-ray sources, ...
  • Radovich, M.; Formicola, I.; Meneghetti, M.; Bartalucci, I.; Bourdin, H.; Mazzotta, P.; Moscardini, L.; Ettori, S.; Arnaud, M.; Pratt, G. W.; Aghanim, N.; Dahle, Håkon; Douspis, M.; Pointecouteau, E.; Grado, A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    We present a mass estimate of the Planck-discovered cluster PLCK G100.2-30.4, derived from a weak lensing analysis of deep Subaru griz images. We perform a careful selection of the background galaxies using the multi-band ...

Barth; Redmond, Susan F.; Rhodes, Jason D.; Robertson, Andrew; Schmoll, Jürgen; Sirks, Ellen; Sivanandam, Suresh (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract The statistical power of weak lensing measurements is principally driven by the number of high-redshift galaxies whose shapes are resolved. Conventional wisdom and physical intuition suggest this is ...
  • De Pontieu, Bart Walter; Martinez-Sykora, Juan; Chintzoglou, Georgios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Spicules are the most ubuiquitous type of jets in the solar atmosphere. The advent of high-resolution imaging and spectroscopy from the Interface Region Imaging Spectrograph (IRIS) and ground-based observatories has revealed ...
  • Carlsson, Mats; Leenaarts, Jorrit; De Pontieu, Bart Walter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    We analyze observations from the Interface Region Imaging Spectrograph of the Mg ii k line, the Mg ii UV subordinate lines, and the O i 135.6 $\mathrm{nm}$ line to better understand the solar plage chromosphere. We also ...
  • de Moortel, Ineke; Howson, Thomas A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract Why the atmosphere of the Sun is orders of magnitudes hotter than its surface is a long standing question in solar physics. Over the years, many studies have looked at the potential role of magnetohydrodynamic ...
  • De Pontieu, Bart Walter; McIntosh, Scott; Martinez-Sykora, Juan; Peter, Hardi; Mendes Domingos Pereira, Tiago (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Spectral observations of the solar transition region (TR) and corona show broadening of spectral lines beyond what is expected from thermal and instrumental broadening. The remaining non-thermal broadening is significant ...
