Galaxy Distribution and Motions| Galaxy Distribution and Motions |
In General > s.a. cosmological principle [homogeneity, isotropy];
matter distribution in cosmology [including cosmic web].
* Distance determination: For nearby galaxies,
variable stars like Cepheids; For other ones, (type Ia) supernovae and Hubble's law.
* 1908: C V I Charlier proposed
a hierarchical model of galaxy distribution.
* 1986: Bubble structure observed from
survey of 1100 galaxies near the galactic north pole, with visible light, and 2700
galaxies in another region, with 21 cm radiation; The size of bubbles is as large as
50 Mpc; These could be formed by first generation explosions (quasars, supernovae?).
* 1989: A galaxy in formation seen
at 65 Mly, 10 times larger than the Milky Way.
* 1994: Galaxies as faint as
magnitude 27 (blue) can be seen with CCDs.
* 1996: Youthful galaxies studied
at z ~ 3.5, 15% of present time, when galaxy formation was under way.
* 1998: 0140+326RD1 at z
= 5.34, other at z = 6.68 [this must have not been confirmed, see 2002].
* 1999: Information on \(5 \times 10^7\)
galaxies collected by Digital Palomar Sky Survey; The most numerous ones are dwarves;
About 104 redshifts have been measured (notice that
z space is not identical with real space, because of virialization).
* 2002: Most distant galaxy so far (not
a quasar) seen at \(z\) = 6.56, or 15.5 Gly, using the Abell 370 cluster as lens.
* 2006: First observational
evidence that galaxies are not randomly oriented, but follow the dark-matter pattern
[@ news sr(06)apr].
* 2009: Large-volume cosmological surveys
reveal that galaxies are distributed along filaments, connected to form a percolating
network, the cosmic web.

* Difference: Galaxy groups differ
from clusters primarily by way of their lower masses, \(M\sim10^{14}\,M_\odot\) vs.
\(M\sim10^{15}\,M_\odot\).
* Largest structure: In 1999, a
filament at least 4 × 108 ly long, perhaps
\(10^9\) ly, in Aquarius, with at least \(10^5\) galaxies.
* Assembly bias: The fact that the
distribution of galaxies and galaxy clusters depends both on the total mass of the
objects and on the assembly history.
