Lyman-alpha forest as a diagnostic for Warm Dark Matter
Andrew Magalich (Lorentz Institute, Leiden University)
ITA "blackboard" Colloquium ( Hephysto link )
Philosophenweg, 12, 106
Show/hide abstract

Abstract
LambdaCDM paradigm is extremely successful at describing the large scale structure formation. However, there is a number of observations suggesting possible deviations from CDM on small scales, such as too-big-to-fail and core-cusp problems. Physically-motivated Warm Dark Matter candidates like Sterile Neutrino WDM could resolve this by introducing small-scale suppression in the Matter Power Spectrum. While the direct measurement of small-scale MPS is challenging, Lyman-alpha absorption spectra of distant quasars provide a proxy to the underlying matter distribution. Interestingly, Lyman-alpha forest Flux Power Spectrum exhibits a cut-off on the scales below ~30 km/s, that could be explained by peculiar velocities, Doppler broadening, physical size of absorbers as well as free-streaming of DM particles. We investigate the origin of the cut-off and implications for searches of DM particle.

Nuclear fusion on Earth: A sustainable energy source?
Matthias Bartelmann
ITA "blackboard" Colloquium ( Hephysto link )
Philosophenweg, 12, 106
Show/hide abstract

Abstract
Nuclear fusion in reactors on Earth has been advertised for decades now as a possible source for virtually unlimited amounts of clean energy. Triggered by a recent request, I will scrutinise this claim under several points of view: (1) fuel supply; (2) radioactive waste; (3) energy logistics; (4) cost efficiency; and (5) timeliness.

Exploring the free-floating planet population with gravitational microlensing
Przemek Mroz (Astronomical Observatory, University of Warsaw)
ARI Institute Kolloquium ( Hephysto link )
ARI Moenchhofstrasse 12-14, Seminarraum 1
Show/hide abstract

Abstract
Theories of planet formation predict the existence of a population of free-floating planets that are not gravitationally tethered to any host star. Gravitational microlensing provides a unique tool for studying these objects. The first results of Sumi et al. (2011) claimed that Jupiter-mass free-floating planets are as common as main-sequence stars. However, these results disagree with censuses of substellar objects in young clusters and star-forming regions and with predictions of planet formation theories. I will present new results of the analysis of a ten times larger sample of microlensing events discovered by the OGLE-IV survey during the years 2010-2018, which shed new light on the population of free-floating planets. I will also discuss prospects for detecting free-floating planets with the future missions, like Euclid and WFIRST.
