Hard X-rays from the galactic nucleus: present and future observations

Goldoni, P.; Laurent, P.; Lebrun, F. +2 more

In spite of increasing evidences of the presence of a massive Black Hole at the Galactic Center, its radio counterpart, Sgr A*, shows little activity at high energies, and recent models involving energy advection (ADAF) have been proposed to explain this difficulty. We present results on the hard X-ray emission from the galactic central square deg…

Supernova Theory

Lattimer, J. M.

Supernova theory relies heavily upon the underlying equation of state (EOS). The role of the EOS during stellar collapse, and recent attempts to delineate the EOS from astrophysical observations, are discussed
