Universidad de Granada.<br /><br />Abstract:</p><p>To characterize the EOS of the dark energy based on SNe Ia Hubble<br />diagrams requires to decrease the present dispersion in the SNIa<br />calibration relation. Systematic effects, like extinction and evolution<br />with redshift, may limit the precision by which SNe Ia could be used to<br />measure Cosmology. Observations indicate that brighter SNe Ia occur only<br />in systems with ongoing star formation and that the majority of SNe Ia<br />comes from young progenitors. In this talk I will focus on the challenge<br />to understand, from a theoretical point of view, the dispersion in the<br />calibration relation and the link between SNIa progenitors and light curves.</p><p> </p><p>Place and time:</p><p>Physics Department meeting room, 2nd floor</p><p>2 June 2010, 14:30 </p><p> <!-- @page { size: 21.59cm 27.94cm; margin: 2cm } P { margin-bottom: 0.21cm } --> </p>
