Are most galaxies elliptical? What are the different types of galaxies? What color is a protostar? What is the redshift of the Virgo cluster of galaxies? How big is an elliptical galaxy? How many irregular galaxies are there? What color are the planets in our solar system?
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...
What are the different types of galaxies? What is a dwarf star? What galaxy is Rigel in? What is a dwarf planet? What galaxies have a blue shift? What is the redshift of the Virgo cluster of galaxies? What is a black dwarf? What is a red dwarf star? What type of galaxy is the...
There are low excitation radio galaxies too, which, on the other hand, are likely very old galaxies where relatively little material is falling into the black hole and no merger signatures are visible. These objects were likely triggered by mergers but looked very different at that time and ...
Their survey was the first to indicate that galaxies were not distributed uniformly in space. Some areas had a lot of galaxies, and other areas had just a few. Another way of putting this is to say that galaxies are clustered. They're not spread evenly throughout the universe. So we hav...
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, ...
A. Galaxies are rotating. B. Galaxies rotate. C. Galaxies are being rotated. D. Galaxies will rotate. 相关知识点: 试题来源: 解析 B。本题考查“星系旋转”的英语表达。A 选项“are rotating”是现在进行时,强调正在旋转;C 选项“are being rotated”是现在进行时的被动语态,不符合星系自然旋转的主动...
There are two possible explanations: 1. There is more stuff (matter) that we don't see with our telescopes. We call this dark matter. 2. Newton's laws and even GR are wrong on the scale of galaxies and everything bigger. This idea is usually called modified gravity (because we need ...
