Emission spectrum of Sagittarius A* and the neutrino ball scenario

The emission spectrum of the supermassive compact dark object at the Galactic center is calculated in the framework of standard thin accretion disk theory assuming that the compact object is a neutrino ball of 2.6 × 10⁶M instead of a supermassive black hole. The neutrino ball scenario could explain the observed radio and infrared emission spectrum of the Galactic center for wavelengths between λ=0.3 cm and λ=10⁻³ cm, if the neutrino mass and the accretion rate fulfil some constraints.
