Scouring the Lyman alpha forest

Rodney N. Guimarães
Observatório Nacional, Rio de Janeiro, Brazil

Abstract
The evolution models in the interpretation of the spiky area that appears in high z quasars spectra, the lyman alpha forest, will be addressed.
Like a prospector who scours the mouth of a river in search of gold, astrophysicists will do the same with the Lyman alpha forest, but in search of metals not so "precious", galaxies in their initial stage of formation and evidence of the smoothness transition scale of the Universe.

Institute of Astrophysics and Space Sciences

Institute of Astrophysics and Space Sciences (IA) is a new but long anticipated research infrastructure with a national dimension. It embodies a bold but feasible vision for the development of Astronomy, Astrophysics and Space Sciences in Portugal, taking full advantage and fully realizing the potential created by the national membership of the European Space Agency (ESA) and the European Southern Observatory (ESO). IA resulted from the merging the two most prominent research units in the field in Portugal: the Centre for Astrophysics of the University of Porto (CAUP) and the Center for Astronomy and Astrophysics of the University of Lisbon (CAAUL). It currently hosts more than two-thirds of all active researchers working in Space Sciences in Portugal, and is responsible for an even greater fraction of the national productivity in international ISI journals in the area of Space Sciences. This is the scientific area with the highest relative impact factor (1.65 times above the international average) and the field with the highest average number of citations per article for Portugal.
