We review recent progress in understanding the mass distributions of the Milky Way dwarf satellite population, with a specific focus on the implications for gamma-ray fluxes from dark matter. We outline a method that self-consitently predicts the gamma-ray fluxes from the satellites using line-of...
We present results from our survey of RR Lyrae stars in the halo of the Milky Way. Since these stars are standard candles, the survey is capable of finding spatial structures in the halo, such as streams of debris left by the destruction of small satellites by the tidal forces of the ...
The white/blue image is the Milky Way, with the central bulge on the left and the plane of the disk running horizontally across the region; the yellow/green dots are the distribution of galaxies in the nearby universe; the Vela supercluster (VSC) region is indicated, running across the Gala...
Astronomers have just discovered two dwarf galaxy candidates orbiting our galaxy. The orientation of these entities suggests there could be up to 500 similar stellar clusters circling the Milky Way, which is more than double previous estimates.
During night time, we can see the stars of the Milky Way Galaxy if we look up in the sky. We can also have a choice to view the diary band of the Milky Way, when it is too dark at night and far from citylights. Besides our Milky Way galaxy, there are millions and millions of...
GALAXIES (星系) OF THE UNIVERSE The Milky Way is only one galaxy among a few hundred million galaxies in our universe (each with hundreds of billions of stars).Galaxies are huge groupings of stars, planets, gas and dust. Our sun is in the Milky Way, which measures about 100,000 light...
Small galaxies orbiting the Milky Way may have arrived via dark matter superhighways stretching across the universe
We report here on extragalactic large-scale structures uncovered by a deep optical survey for galaxies behind the southern Milky Way. Systematic visual inspection of the ESO/SRC survey revealed over 10000 previously unknown galaxies in the region 265° l 340°, ∣b∣ 10°. With subsequently ...
Stars speed around the Milky Way at hundreds of kilometres per second, but the fastest of them can travel upward of 1,000km/s and are known as hyper-velocity stars. The consensus has been that these fast moving stars start their lives in the middle of the Milky Way, before being flun...
