例句與造句

1. Larger axial ratios can be explained by observing face-on disk galaxies " or " by having a sample of spheroidal ( bulge-dominated ) galaxies.
2. Many galactic bulges are thought to host a supermassive black hole at their centers : however pure disk galaxies with no bulges but with growing central black holes were found.
3. The study reports " the discovery of strong barred structures in massive disk galaxies at z ~ 1.5 in deep rest-frame optical images from CANDELS ".
4. The kinematics of disk galaxies are usually determined by 21-cm emission lines, which are typically not present in lenticular galaxies due to their general lack of cool gas.
5. Some bulges have similar properties to those of elliptical galaxies ( scaled down to lower mass and luminosity ); others simply appear as higher density centers of disks, with properties similar to disk galaxies.
6. It's difficult to find disk galaxies in a sentence. 用disk galaxies造句挺難的
7. It is a relatively simple model that predicts many properties observed in the universe, including the relative frequency of different galaxy types; however, it underestimates the number of thin disk galaxies in the universe.
8. Even though regular disk galaxies do not appear to harbor massive black holes, if two disk galaxies with small black holes collide, the merger would produce an elliptical galaxy with conditions feeding the appetites of growing black holes.
9. Even though regular disk galaxies do not appear to harbor massive black holes, if two disk galaxies with small black holes collide, the merger would produce an elliptical galaxy with conditions feeding the appetites of growing black holes.
10. Also, in some cases, gas flowing to the center of a disk galaxy could gradually create a " pseudo bulge, " as opposed to a primordial bulge, where a black hole could accumulate mass.
11. In 2008 in Bonn together with Jan Pflamm-Altenburg he pointed out that the IGIMF theory implies that disk galaxies have a radial star formation law, in which the star formation density is proportional to the radial gas density.
12. They are thought to form when two galaxies gravitationally interact with each other . " The bizarre configuration could be caused by the chance capture of material from another galaxy by a disk galaxy, with the captured debris strung out in a rotating ring.
13. The stars of this galaxy are concentrated in two disks of similar size and surface brightness, one nested within the other and it has been suggested it's the product of the disk galaxies, each one counter-rotating with respect to the other.
14. If disk galaxies merge with another galaxy of comparable mass ( at least 15 percent of its mass ) the merger will likely destroy, or at a minimum greatly disrupt the disk, and the resulting galaxy is not expected to be a disk galaxy ( see next section ).
15. If disk galaxies merge with another galaxy of comparable mass ( at least 15 percent of its mass ) the merger will likely destroy, or at a minimum greatly disrupt the disk, and the resulting galaxy is not expected to be a disk galaxy ( see next section ).
