Dark matter (and dark mediators) at the LHC
Abstract: The LHC results on dark matter from Run-1 were mostly interpreted in the framework of effective field theories. Simplified models involve new mediators between the Standard Model and the Dark Sector and allow for richer phenomenology and more complex interpretations. Possible dark matter search strategies at the LHC in Run-2 will be discussed.

Dark Matter Self-Interactions via Collisionless Shocks in Cluster Mergers
Abstract: While dark matter self-interactions may solve several problems with structure formation, so far only the effects of two-body scattering of dark matter particles have been considered. I will discuss a scenario where a subdominant component of dark matter is charged under an unbroken U(1) gauge group. In this case collective plasma effects need to be taken into account to understand the dynamics of the interacting DM. Plasma instabilities can lead to collisionless dark matter shocks in galaxy cluster mergers. I will discuss the observations made in the Abell 3827 and 520 clusters in this context.

Title: Journey to the Beginning of Time: Gravitational Waves, Inflation and Fundamental Physics
Abstract: Gravitational Waves from Inflation may have been discovered, or may soon be discovered. If they are, this will push our empirical handle on the universe back in time by 49 orders of magnitude, and will allow us to explore issues ranging from supersymmetry to grand unification, the quantum theory of gravity, and even the possible existence of other universes.

Polywell Fusion – Electric Fusion in a Magnetic Cusp
Abstract: Nuclear fusion power is considered the ultimate energy source because of its nearly inexhaustible supply of cheap fuels,
intrinsic safety, zero carbon emissions and lack of long-lived radioactive waste. In this talk, I will introduce the Polywell fusion concept that may offer a low cost and rapid development path to power the world economically and sustainably. As conceived by Dr. Robert Bussard at Energy Matter Conversion Corporation (EMC2) in 1985, the Polywell fusion concept combines electric fusion with magnetic cusp confinement. This allows the Polywell reactor to be small, stable, and highly efficient. Recently, EMC2 carried out an experiment that demonstrated dramatically improved high-energy electron confinement in a magnetic cusp system operating at beta (=plasma pressure/magnetic field pressure) near 1. This result has significant implications for cusp related schemes for producing controlled nuclear fusion power.

The Strategic Research Council (SRC) at the Academy of Finland : Apply for strategic research funding
————————————————————————————————————-
The SRC’s call will be implemented in two stages. The first stage, for letters of intent, will be open in the Academy of Finland’s online services between 5 November and 9 December 2015.
In addition, the SRC will open a supplementary call within the 2015 programme A Climate-Neutral and Resource-Scarce Finland. https://flamma.helsinki.fi/en/notifications/apply-for-strategic-research-funding
