61. X-ray Polarization in Supernova Remnants

The fast shocks in supernova remnants are known to accelerate particles to extremely high energies. The acceleration process is closely tied to the magnetic field structure in the shock region. This, in turn, can be modified considerably by the shock. Synchrotron emission from the shock regions provides crucial details about the magnetic field strength and orientation through its polarization....

82. Canonical gauge theory of gravitation for fermions

For gauge theories based on the action principle, the covariant Hamiltonian formalism is the description of choice as one can then take advantage of the canonical transformation framework. The latter restricts transformations of the dynamical variables to exactly those that follow from a generating function, which entails by construction that the form of the action principle is maintained and...

57. Dark Energy and Inflation as effects of torsion and geometry in the Covariant Canonical Gauge theory of Gravity (CCGG)

Talk

CCGG is a mathematically rigorous derivation of the coupling of matter and spacetime geometry from a few basic postulates. The framework, based on the canonical transformation theory in the covariant de Donder-Hamiltonian formulation, yields a classical Palatini field theory extending the Einstein-Hilbert ansatz by an admixture of quadratic gravity. That term, quadratic in the Riemann-Cartan...

64. Studying the onset of deconfinement with multi-messenger astronomy of neutron stars

David Blaschke (University of Wroclaw)

Talk

One of the most intriguing questions in the astrophysics of neutron stars is whether their interiors harbour deconfined quark matter. With the first multi-messenger observation of a binary neutron star merger (GW170817) new constraints became available for masses and radii of neutron stars. In this lecture, I will discuss what we may infer for their mass and the central density at the onset of...

123. A virtual tour of the recent results of the Pierre Auger Observatory

Lucas Nellen (National Autonomous University of Mexico - UNAM)

Talk

The Pierre Auger Observatory, covering an area of 3000 km$^2$ is currently the larges observatory to study the highest energy cosmic rays, with energies above $10^{18}$ eV. The main part observatory consists of a surface detector with about 1600 stations, spaced 1.5 km apart, and 4 fluorescence detector sites with a total of 17 telescopes, overlooking the surface detector. We will start our...
