This broken profile results in a half-light radius of 5.75卤0.38kpc, significantly larger than that inferred from a single-exponential disk profile but consistent with that of local disk galaxies of similar mass. We also confirm that the size growth history of the Milky Way is broadly ...
The solar system is the family of the Sun, planets, and the satellites of the planets, asteroid, meteoroids, and comets. Millions of solar systems are present in our galaxy called Milky Way. Answer and Explanation: The solar system is a...
Gas column density,emission(EM)and dispersion(DM)measure have been computed from inside the simulated disk at a position of 8 kpc from the center and in several directions. Our preliminary results reveal that the distribution of hot gas is non-isotropic according with observations(Gupta et al. ...
At a fixed stellar mass, Milky Way-like (MW-like; Mstellar5×1010M⊙) disc galaxies have, on average, increased their sizes by a factor of two in the last 8 Gyr, while the surface stellar mass density at the edge position (Σedge) has decreased by more than an order of magnitude ...
