For this image, I used an IDAS LPS EOS clip-in filter to reduce targeted wavelengths of artificial light from the city. If you are having trouble finding this filter online, I suggest checking out theOptolong L-Pro filter. This is an excellent choice for broad-spectrum targets such as gal...
We present the first sample of quasi-stellar objects (QSOs) behind the southern satellite galaxies of the Milky Way. These objects were sought for use as unresolved, inertial reference objects in proper motion studies of the Fornax, Carina and Sculptor dwarf spheroidal galaxies and the Small Mage...
One tail trails the star cluster, the other pulls out ahead of it. They are known as tidal tails, and have been widely studied in colliding galaxies but no one had ever seen them from a nearby open star cluster, until very recently. The key to detecting tidal tails is spotting which ...
Using the "Updated Nearby Galaxy Catalog", we consider different properties of companion galaxies around luminous hosts in the Local Volume. The data on stellar masses, linear diameters,surface brightnesses, HI-richness, specific star formation rate (sSFR), and morphological types are discussed for ...
There are 9 dwarf spheroidal galaxies in the neighbourhood of the Galaxy. The last to be discovered is in Sagittarius (Ibata et al 1994), situated at a dis... AA Zijlstra,G Dudziak,JR Walsh - Springer Netherlands 被引量: 26发表: 1997年 The Three Dimensional Shape of the Sagittarius Dwa...
While scientists believe all galaxies have a black hole at their nucleus, some extremely large galaxies have quasars at their core. A quasar is a black hole that is so massive that it produces 1,000 times the light produced by all the objects in the Milky Way galaxy....
Distances to celestial bodies are crucial in astronomy. They allow astronomers to understand the structure of the Universe; for example, to see the organization of the Solar System and to recognize that galaxies lie beyond the Milky Way. The derived physical sizes of bodies scale with the ...
