Vojtech Witzany (Astronomical Institute of the Czech Academy of Sciences)

A compact stellar mass object inspiralling onto a massive black hole deviates from geodesic motion due to radiation-reaction forces as well as finite-size effects. Such deviations need to be included with sufficient precision into wave-form models for the upcoming space-based gravitational-wave detector LISA. I will present the formulation and solution of the Hamilton-Jacobi equation of a generic geodesic in Kerr space-time perturbed by the spin-curvature coupling, the leading order finite-size effect. In return, this solution allows to compute a number of observables such as the...

Dr. Victor Goncalves (Universidade Federal de Pelotas, Brasil)

Abstract:

In this talk I will discuss the contribution of the heavy quark production in ultra high energy cosmic ray interactions in the atmosphere considering that the primary cosmic ray can be either a photon, neutrino or a proton. A detailed mapping of the dominant kinematical domains contributing to the prompt atmospheric neutrino flux at high neutrino energies is presented by studying their sensitivity to the cuts on several kinematical variables crucial for charm production in cosmic ray scattering in the atmosphere. Finally, recent results for the prompt tau...

Dr. Bruno Beccard (Nicolet Spectroscopy Research Center, Trappes, France)

Several infrared absorption measurements such as molecular orientation, thin films on reflective surfaces and crystal structure studies are enhanced with the use of polarized light. Sequentially collected sample and reference spectra are measured using infrared polarizer accessories. Infrared Reflection Absorption Spectroscopy (IRRAS) uses p-polarized light at a grazing angle of incidence to measure thin films on metallic substrates. The reflectance measurement is done at a grazing angle to increase the polarized absorption from the thin film. Often the absorptions from these samples are...
