These spinning, galaxy-sized plasma clouds were the first protogalaxies. Like
elliptical galaxies, they begin spherical or elliptical in shape. Because the
protogalaxies were created from larger plasma filaments, they each streamed
through ...

High Redshift and Primeval Galaxies
TESTS Ongoing searches for protogalaxies provide an important test of some of
these ideas. Figure 3a plots the predicted number of protogalaxies per square
degree versus red magnitude, and various models are shown. Limits are set by ...
Jacqueline Bergeron, 1987

Panchromatic View of Galaxies: Their Evolutionary Puzzle : ...
Protogalaxies have proved notoriously evasive. The early expectations that
forming galaxies underwent an ultraluminous phase at moderate redshift
stimulated deep searches that have hitherto failed to find candidates of the
requisite ...

The Formation of the Milky Way
We use the most common triaxial model for initial conditions of protogalaxies.
The body of protogalaxies is modelled by triaxial ellipsoids with semiaxes A, B
and C. For initial velocity fields we propose the lineal distibution which is defined
by ...

The Large Scale Structure of the Universe: International ...
One can account for intracluster gas if the enriched matter produced by ordinary
stellar evolution in protogalaxies stays in gaseous form (De Young 1977): only if
coeval formation of galaxies and clusters occurs does this seem easy to arrange.
M. S. Longair, Jaan Einasto, 1978

Gravitational Physics of Stellar and Galactic Systems
<58J8). Hoyle ( 1 949) was the first to calculate tidal transfer of angular
momentum among protogalaxies, and he concluded that it would be significant.
We can readily see this from (58.18) because TM is approximately the dynamical
timescale ...

Cosmology: A First Course
1.1.4 Primordial galaxies and protogalaxies One sign that a galaxy is young is
the presence of very young, in the sense of recently formed, bright, blue (owing to
their high surface temperature) stars. Another, observable essentially in the ...

Exact Solutions and Scalar Fields in Gravity: Recent ...
Whatever the Universe composition was, protogalaxies were originated due to a
spectrum of scale-invariant perturbations [5, 6] that was present within the
cosmological background at the beginning of structure formation; the inflationary
...

A Grand and Bold Thing: An Extraordinary New Map of the ...
Inside these spiraling and spherical protogalaxies, the hydrogen not fused into
stars is pulled toward their centers, getting denser and denser until somehow—
no one knows how—gravity wins completely. The hydrogen's mass collapses to a
...

History of the Universe
According to cosmological models, early galaxies (called protogalaxies)
appeared between 100 million and 250 million years after the creation and were
the homes of the first stars. To begin with the dark matter was scattered fairly
uniformly ...
