Milky Way Mass refers to the total mass of the Milky Way galaxy, including its dark halo, which is approximately 10^12 times the mass of the Sun. This mass is estimated through various measurements, such as the orbits of satellites and the distribution of standard candles, with some uncertai...
and in particular to the Milky Way’s dominant stellar component, itsDisk, which contains about three quarters of all Galactic stars. As a shorthand, we will use the termDisk(capitalized) to refer to the ‘Milky Way’s stellar disk’. All other disks will be labeled...
We know what both of these breathtakingly beautiful galaxies look like because we can see them from afar. How then do we know what our own Milky Way galaxy looks like, seeing as how we are inside it? While we've never been able to zoom out and take a true galac...
A number of Milky-Way like DM halos with similar mass and evolution history to those of the Milky Way were identified in the Aquarius simulations. In the work reported here we used the initial condition of the “C” halo. This is because the final main galaxy formed in the Aquila ...
