A simple model of radiative emission in M87

Risultato della ricerca: Articlepeer review


We present a simple physical model of the central source emission in the M87 galaxy. It is well known that theobserved X-ray luminosity from this galactic nucleus is much lower than the predicted one, if a standard radiativeefficiency is assumed. Up to now the main model invoked to explain such a luminosity was the ADAF (advectiondominatedaccretion flow) model. Our approach supposes only a simple axisymmetric adiabatic accretion with alow angular momentum together with the bremsstrahlung emission process in the accreting gas. With no other specialhypothesis on the dynamics of the system, this model agrees well enough with the luminosity value measured byChandra
