The majority of bright early-type galaxies in this field are found at redshifts $z \\leq 1.3$ to share common properties with those of high-z cluster samples, as for the age and mass of the dominant stellar population -- which are found to be as old as 3-5 Gyr and as massive as...
The most beautiful type of galaxies are Spiral Galaxies. Its spiral arms are circling waves whichform new stars. This shaped galaxy consists of a flat disk with a bulge in the center and spiral arms. This flat shape disk includes stars, planets, gases and dust particles which revolve around ...
Among early-type galaxies with almost circular isophotes, E0 and E1 galaxies are, at 99.3% significance, more luminous than face-on objects classified as S0(0) and S(0)(1). This result supports the view that rotation and "diskiness" are more important in the outer regions of faint early...

What are the space stations equipped with to observe distant stars and galaxies? A. Microscopes. B. Cameras. C. Advanced telescopes. D. Binoculars. 相关知识点: 试题来源: 解析 C。解析:“The space station is also equipped with advanced telescopes to observe distant stars and galaxies.”。
The scaling relation for early type galaxies in the 6dF galaxy survey does not have the velocity dispersion dependence expected from standard stellar population models. As noted in recent work with SDSS, there seems to be an additional dependence of mass to light ratio with velocity dispersion, ...
Star clusters are large gravitationally bound groups of stars that are one of the best tools astronomers have to study stellar evolution.
