Interaction between dark matter sub-halos & galactic gaseous disk
Interaction sub-halos galactic gaseous disk
2011/10/8
We investigate the idea that the interaction of Dark Matter (DM) sub-halos with the gaseous disk of galaxies can be the origin for the observed holes and shells found in their neutral hydrogen (HI) di...
Star formation in the extended gaseous disk of the isolated galaxy CIG 96
extended gaseous disk isolated galaxy CIG 96
2011/9/27
We study the Kennicutt-Schmidt star formation law and efficiency in the gaseous disk of the isolated galaxy CIG 96 (NGC 864), with special emphasis on its unusually large atomic gas (HI) disk (r_HI/r_...
Binaries migrating in a gaseous disk: Where are the Galactic center binaries?
accretion accretion disks binaries general Galaxy center hydrodynamics methods: numerical
2010/11/9
The massive stars in the Galactic center inner arcsecond share analogous properties with the so-called Hot Jupiters. Most of these young stars have highly eccentric orbits, and were probably not forme...
Evolution of gaseous disk viscosity driven by supernova explosion. II. Structure and emissions from star-forming galaxies at high redshift
gaseous disk viscosity driven supernova explosion
2011/1/10
(Abridged) High redshift galaxies are undergoing intensive evolution of dynamical structure and morphologies. We incorporate the feedback into the dynamical equations through mass dropout and angular ...
An Inner Gaseous Disk around the Herbig Be Star MWC 147
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/27
We present high-spectral-resolution, optical spectra of the Herbig Be star MWC 147, in which we spectrally resolve several emission lines, including the [O I] lines at 6300 and 6363\deg.
