Join us for this Open Science Lunch to learn about the work on reforming research assessment in Norway and hear about experiences from implementing the CoARA commitments. 

We invite you to the April RoCS Solar/Stellar Lunch. You are invited to discuss your work with colleagues.

Welcome to our weekly lunch seminar held in the dScience lounge with Thomas Schellenberger.

Each spring, near the date of Svein Rosseland's birthday, the Institute of Theoretical Astrophysics invites everyone to a guest lecture by an internationally renowned astrophysicist as a remembrance for our great astrophysicist Svein Rosseland (1894-1985), founder of our institute.

Abstract: Although tropical vector bundles have been introduced by Allermann ten years ago, very little has been said about their structure and their relationship to vector bundles on algebraic varieties. I will present recent work with Martin Ulirsch and Dmitry Zakharov that changes exactly this in the case of curves: we prove analogues of the Weil-Riemann-Roch theorem and the Narasimhan-Seshadri correspondence for tropical vector bundles on tropical curves. We also show that the non-Archimedean skeleton of the moduli space of semistable vector bundles on a Tate curve is isomorphic to a certain component of the moduli space of semistable tropical vector bundles on its dual metric graph. Time permitting I will also report on work with Inder Kaur, Martin Ulirsch, and Annette Werner and explain some of the difficulties that arise when generalizing beyond the case of curves to Abelian varieties of arbitrary dimension.

Time and again, a product is being developed, approved, and launched, only to flop in the marketplace. So how can you get your ducks in a row to prepare for a successful product, and how early should you start this process?

Ana Lucía Campaña Perilla will defend her thesis "Palladium-based nanoparticles produced by Escherichia coli:
Insights into synthesis and physicochemical characterization of microbial nanoparticles." for the degree of Philosophiae Doctor at the University of Oslo, Faculty of Mathematics and Natural Sciences.

C*-algebra seminar by Emilie Elkiær.

We consider several situations where drops can be captured by fibrous materials, from sprays on textiles (where the droplets are much larger than the typical fiber size) to meshes placed in a flow of fog (where the droplets are smaller than the typical fiber size). This last system, often encountered in aerosol filtration, exhibits a wealth of phenomena coupling capillarity and aerodynamics. In particular, we characterize experimentally and theoretically the deposition of the mist droplets on the fibre and the flow through and around the porous mesh, that both strongly depend on the mesh porosity and fine structure (i.e. the arrangements of the fibers). We further consider the dynamics of large drops sitting on fibers when exposed to a cross-flow, in particular their interactions with their unsteady wakes.

A liquid droplet placed on a rigid, planar surface has a captivating simplicity: its surface is a spherical cap and remains in equilibrium. In this talk, I’ll show that the addition of a deformable boundary leads to a range of new phenomena: evaporating droplets with an elastic skin may develop flat tops, but even without a complex rheology, reaching equilibrium can happen slowly, with the droplet’s contact ageing. I will discuss two specific examples, presenting a combination of theory and experiment for each.
