State Transitions and Time Variations of Black Hole Accretion Flows

Ryoji Matsumoto

Chiba University

Black hole candidates display transitions between hard and soft X-ray states. During the transition, quasi-periodic oscillations and jet ejections are observed, and the black hole accretion flow shows intense activity. Our group has investigated the process of the formation of the soft X-ray emitting region by the cooling of the...

A fierce new challenge: unveiling the connection between the first galaxies and reionization

Enrico Garaldi

Max-Planck-Institut für Astrophysik

The Epoch of Reionization (EoR) shaped the properties of the baryonic content of the Universe. Using hydrodynamical and radiative-transfer numerical simulations, we investigate in detail the processes taking place in the IGM before, during and after the EoR. Present and future observations by, e.g., PAPER, LOFAR, SKA, and E-ELT, will...
