The Internet Galaxy: Reflections on the Internet, Business, and Society
, 2001From the Publisher: Manuel Castells is one of the world's leading thinkers on the new information age, hailed by The Economist as "the first significant philosopher of cyberspace," and by Christian Science Monitor as "a pioneer who has hacked out a ...

Galaxies and Clusters of Galaxies [PDF]
, 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.

Galaxies and Clusters of Galaxies
1987Numerous 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.

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, 1984Debate 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.

Few galaxies are loners: almost all are members of groups of at least a dozen systems. The Milky Way is no exception. It is the second brightest in a group of three dozen, mostly dwarf, galaxies. The brightest member of the Local Galaxy Group is the Andromeda Spiral M31. The most luminous members of the Local Group, including all those visible with any

Cold streams in early massive hot haloes as the main mode of galaxy formation
Nature, 2008Massive galaxies in the young Universe, ten billion years ago, formed stars at surprising intensities. Although this is commonly attributed to violent mergers, the properties of many of these galaxies are incompatible with such events, showing gas-rich ...
