A population of red candidate massive galaxies ~600 Myr after the Big Bang

Nature, 2022
James Webb Space Telescope early release observations used to search for intrinsically red galaxies from the first 750 million years of cosmic history find six candidate massive galaxies, possibly including one of roughly 10^11 solar masses.

An Analytical Model for Spherical Galaxies and Bulges

, 1990
Un modele de masse pour les galaxies elliptiques, qui approche la loi R 1/4 de Vaucouleur, est developpe. Il est demontre que les proprietes intrinseques et les distributions de densite de ce modele peuvent etre evaluees analytiquement.

Galaxies and Clusters of Galaxies [PDF]

open access: possible, 2002
The leap into deep space outside our Milky Way Galaxy, into the realm of the distant galaxies (or the extragalactic nebulae, as they were formerly called), and the beginnings of a cosmology based on observations, will be considered throughout history to be one of the most important achievements of the 20th century.

LUMINOUS INFRARED GALAXIES

, 1996
▪ Abstract At luminosities above 1011 , infrared galaxies become the dominant population of extragalactic objects in the local Universe (z ≲ 0.3), being more numerous than optically selected starburst and Seyfert galaxies and quasi-stellar objects at ...

Galaxies and Clusters of Galaxies

1987
Numerous galaxies similar to our own can be observed at distances far beyond the boundaries of our Galaxy. Sometimes they are referred to as “extragalactic nebulae” because they look like faint nebulae when seen through small telescopes. Consequently they were initially given names such as the “Magellanic Clouds”, the “Andromeda nebula” and so forth.

Galaxies and Galaxy Groups

2000
Before stellar evolution theory reached its present stage, galactic evolution ideas were tentative and depended not so much on physical arguments (e.g. galactic dynamics) but intuitive notions based on observations of galaxy shapes. Historically this is quite understandable.

The Origin of Galaxies and Clusters of Galaxies

Science, 1984
Debate on how galaxies and clusters of galaxies formed has reached an interesting stage at which one can find arguments for quite different scenarios. The galaxy distribution has a complex "frothy" character that could be the fossil of a network of protoclusters or pancakes that produced galaxies.
