(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 ...

(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 ...

(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 ...

(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 ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Recently, a modified theory of gravity was presented, which consists of the superposition of the metric Einstein-Hilbert Lagrangian with an f(R) term constructed à la Palatini. The theory possesses extremely interesting ...
