SEMINARIO: Dra. Ginevra Favole

Título:Star-forming galaxies as tools for cosmology in new-generation 
spectroscopic surveys.


Resumen:

In this talk I will present the results of my PhD Thesis, which is a 
collection of clustering studies in different  galaxy samples selected 
from the Sloan Digital Sky Survey and the SDSS-III/Baryon Oscillation 
Spectroscopic Survey.

By measuring the two-point correlation function of galaxy populations 
that differ in redshift, color, luminosity,  star-formation history and 
bias, and using high-resolution large-volume cosmological simulations, I 
have studied the clustering properties of these galaxies within the 
large scale structure of the Universe, and those of their host dark 
matter halos. The aim of this research is to stress the importance of 
star-forming galaxies as tools to perform cosmology with the new 
generation of wide-field spectroscopic surveys.

Among the galaxies considered, I have focused my investigation on a 
particular class whose rest-frame optical spectra exhibit strong nebular 
emission lines. Such galaxies, better known as Emission-Line Galaxies 
(ELGs), will be the main targets of near-future missions that will use 
ELGs up to z ~ 2 to trace star formation and to measure the Baryon 
Acoustic Oscillations as standard ruler, in the attempt to unveil the 
nature of dark energy.

Therefore, understanding how to measure and model the ELG clustering 
properties, and how they populate their host dark matter halos, are 
fundamental issues that I will describe in this talk.
