On the structure and mass of the galactic halo

  • S. Ninković
Article

Abstract

On the basis of a globular cluster study a crude estimate of the total mass of the galactic halo within 20 kpc from the centre is done. It gives a minimal halo mass of the order of\(10^{10} \mathfrak{M}_ \odot \), yielding possibilities for a mass as large as\( \sim 10^{11} \mathfrak{M}_ \odot \). The content of the interstellar matter in the halo is estimated too. It is found that the gas content is a few percents the minimal mass, the gas temperature is very high — about 1×106 K, the magnetic field weak — about 0.25 nT. A weak nonthermal radio emission might be expected from such a halo.
