Astronomers observe early stages of Milky Way-like galaxies in distant universe
Astronomers early stages Milky Way-like galaxies distant universe
2017/3/30
For decades, astronomers have found distant galaxies by detecting the characteristic way their gas absorbs light from a bright quasar in the background. But efforts to observe the light emitted by the...

In this paper the problem of the phenomenological modelling of
elliptical galaxies using various available observational data is presented. Recently,
Tortora, Cardona and Piedipalumbo (2007) suggest...
Influence of the Black Hole Rotation on Accretion Discs and Jets in Active Galaxies: the Case of NGC 1068
the Black Hole Rotation Accretion Discs and Jets Active Galaxies the Case of NGC 1068
2010/10/18
Although we do not observe directly black holes in the Universe, their presence has been inferred in several astrophysical systems, from galactic to extragalactic scales. In this work, we will restric...
