Irene Margrethe Kaltenborn In KHM1 gallery IreneMargrethe Kaltenborn´s MFA exhibition Choreographies towards loss set the stage for the audience to enter artworks which echoed loss and a void, full of wonderment and poetics. The gallery was dimly lit and kept minimal, leaving room for the viewer to enter the web of interconnectedness between animals, humans and nature.       What has the process b

När vi blickar upp mot natthimlen (och om vi har tur) ser vi stjärnor. Några förefaller stora och ljusstarka, andra små och ljussvaga. Dock ser vi dem bara som ljusa punkter, även när vi tittar genom stora teleskop. Vi kan alltså inte direkt urskilja ytorna på dessa avlägsna solar och tvingas utröna deras egenskaper från det samlade stjärnljuset. Undantaget är vår egen stjärna, solen, vars yta är For testing three-dimensional (3D) hydrodynamic models of stellar atmospheres, spectroscopy across spatially resolved stellar surfaces with high spectral resolution is desired. 3D models predict center-to-limb changes in asymmetries, shapes, strengths and wavelength positions of spectral line profiles, reflecting the hydrodynamics of the stellar atmosphere. However, except for a few supergiants an

Teoretiska fysiker tycker verkligen om att bygga modeller av sin omvärld för att kunna göra förutsägelser om den. En av de mest lyckade teoretiska modellerna är standardmodellen inom partikelfysik. Med den har fysiker lyckats förklara och förstå hur universums allra minsta beståndsdelar fungerar. Den har till och med vid ett flertal tillfällen lyckats att förutsäga existensen av nya partiklar, somIn recent years, the BaBar, Belle and LHCb experiments have observed an excess of $B\to D^{(*)}\tau\nu$ decays compared to Standard Model predictions. In this thesis, we investigate if it is possible to explain this excess with a two Higgs doublet model using the Froggatt-Nielsen framework. Two Higgs doublet models allow new decays at tree-level and the Froggatt-Nielsen mechanism gives an explanat

Dubbel ickebeskattning på grund av tillämpning av skatteavtal kan definieras som den skattemässiga effekt som inträder då varken hemviststaten eller källstaten har något beskattningsanspråk i förhållande till en viss inkomst men där inkomsten skulle ha beskattats av någon stat i frånvaro av skatteavtalet. Hittills har intresset och förståelsen för de bakomliggande orsakerna varit begränsad och det

Truls Törnqvist, a mentor in the LUSEM Mentorship Programme, shares his experiences and reflections on the importance of guidance during the transition from academia to professional life. He discusses the joys of mentoring, the impact it has had on his own development, and offers practical advice for both mentors and mentees to foster successful mentorship relationships. Hi Truls!

On November 21-22, SWEAH's research conference is arranged for everyone who is active in the research school at the 13 affiliated universities – a big event and the first major event for most of the future researchers in the conference committee. Chairman Mahwish Naseer and the other junior researchers on the committee have busy days. For several months, they have planned this year's SWEAH confere

Using kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial resolution achieved in optical astronomy by an order of magnitude, enabling images of rapidly rotating hot stars with structures in their circumstellar disks and winds, or mapping out patterns of nonradial pulsations across stellar surfaces. Intensity interferometry (once pio

A new Monte Carlo method for computing thermodynamical properties of very large polyelectrolytes is presented. It is based on a renormalization group relating the original polymer to a smaller system, where, in addition to the naively rescaled forces, a corrective nearest-neighbor interaction originating from the short distance Coulomb cutoff is introduced. The method is derived for low T but is i

Unraveling functional and ancestral relationships between proteins as well as structure prediction procedures require powerful protein alignment methods. This paper describes the use of fuzzy alignments when matching protein structures. The method use mean-field annealing optimization of fuzzy alignment variables, based on a cost expressed in terms of distances between aligned atoms and of gaps. T

A lattice model for fibril formation on the basis of general peptide interactions is presented. Fibrils are well-structured protein aggregates and a key phenomenon in many diseases, among them Alzheimer. We study the model’s equilibrium and kinetic properties using Wang-Landau sampling and a Metropolis Monte Carlo algorithm with cluster moves. The peptides are shown to form ordered fibrilar aggreg

Context. Elements heavier than Li are produced in the interiors of stars. However, for many elements the exact production sites and the timescales on which they are dispersed into the interstellar medium are unknown. Having a clear picture on the origins of the elements is important for our ability to trace and understand the formation and chemical evolution of the Milky Way and its stellar popula

The Cherenkov Telescope Array (CTA) is the next-generation gamma-ray observatory currently under construction. It will improve over the current generation of imaging atmospheric Cherenkov telescopes (IACTs) by a factor of five to ten in sensitivity and it will be able to observe the whole sky from a combination of two sites: a northern site in La Palma, Spain, and a southern one in Paranal, Chile.

Ground-based, high-resolution spectrographs are providing us with an unprecedented view of the dynamics and chemistry of the atmospheres of planets outside the Solar System. While there are a large number of stable and precise high-resolution spectrographs on modest-size telescopes, it is the spectrographs at observatories with apertures larger than 3.5 m that dominate the atmospheric follow-up of
