Title: Comparing the Norkyst 800 model to in situ measurements in the outer Oslofjord

Supervisor: Joe LaCasce

Carmelo Evoli, Universität Hamburg [slides]

At GeV-TeV energies the propagation of CRs in our Galaxy is diffusive. Current models of galactic propagation are based on a simplified approach for which diffusion is constant and isotropic. In fact, diffusion transport must be described as in-homogenous and anisotropic and experimental data have now reached an accuracy that allows to study such effects.  

In my talk, I will present some of the consequences of adopting realistic diffusion models for the propagation of galactic CRs, and I will show how these models allow a better understanding of local observations and diffusion emissions within an unified framework.

In the second part of my talk, I will focus on antiprotons as a tool to set constraints on DM models.  In particular, I will discuss the uncertainties associated to both standard astrophysical and DM originated antiprotons. I will show on which extent current antiproton data can place tight constraints on DM models, excluding some of those suggested in connection with indirect and direct searches.

Late Lunch Talk by Heidi Nistelberger

by Reidar G. Trønnes. More info here:

Welcome to the SECOND conference on Stochastics of Environmental and Financial Economics. The conference will bring together leading researchers in the fields of stochastic analysis and finance to discuss recent developments and challenges with an edge towards energy, environmental and financial markets.

The conference is also a celebration of professor Bernt Øksendal's 70th anniversary. On Thursday April 23 the program of the conference will mark this big event with a selected list of speakers.

The conference is organized by the Center of Advanced Studies (CAS), Stochastics of Environmental and Financial Economics. Scientific organizers: Fred Espen Benth and Giulia Di Nunno (UiO)

Réamonn Ó Buachalla (IMPAN) will give a talk with title: Noncommutative Kähler structures on quantum homogeneous spaces

Abstract:

Building on the definition of a noncommutative complex structure for a general algebra A, I will introduce the notion of a noncommutative Kähler structure for A. In the special case where A is a quantum homogeneous space, I show that many of the fundamental results of classical Kähler geometry follow from the existence of such a structure: Hodge decomposition, Serre duality, the Hard Lefschetz theorem, the Kähler identities, and collapse of the Frölicher spectral sequence at the first page. We then apply these results to Heckenberger and Kolb's differential calculus for quantum projective space, and show that they have cohomology groups of at least classical dimension. Time permitting, I will also discuss the relationship of this work to Connes proposal to study positive Hochschild cocycles as a starting point for noncommutative complex geometry, and Fröchlich, Grandjean, and Recknagel's definition of a Kähler spectral tuple.

CEES Extra Seminar by Masahito Tsuboi from Uppsala University. 

Marco Cirelli, Saclay, France [slides]

The field of Dark Matter Indirect Detection is in a thriving but somewhat chaotic moment: quite a few hints of possible detection of signals of DM (over a large range of masses and, in general, inferred properties) are confronted with stringent constraints, often based on the same experiments that provide the possible hints. In turn, this spurs a lot of theoretical activity, aimed at phenomenologically analyzing the claims and, perhaps, at embedding them in wider model building. I will briefly review the current status of the searches, mention the most debated hints and sketch the general directions of the theory activity.

Title: How to account for ‘more realistic’ aerosol properties in climate models and remote sensing retrievals?

Since 2010, Norsonic has in collaboration with Squarehead been selling acoustic camera for the commercial market. But who buys it, what is it used for, and what trends can we see in the future for beamforming systems?

Jørgen Grythe at Norsonic will try to address these points including a presentation of their range of products in beamforming, with a live demonstration of one of their acoustic cameras. Join this presentation to see what the mathematical equations governing array signal processing mean in the physical world, and the chance to get your hands on an acoustic camera to try it yourself.
