Advances on GRB as cosmological tools
G. Ghirlanda
Several interesting correlations among Gamma Ray Bursts (GRB) prompt and afterglow properties have been found in the recent years. Some of these correlations have been proposed als…
Spectral libraries and their uncertainties
Paula Coelho
Libraries of stellar spectra are fundamental tools in the study of stellar populations and in automatic determination of atmospheric parameters for large samples of observed stars.…
"Ab initio" models of galaxy formation: successes and open problems
Gabriella De Lucia
In the past decades, different approaches have been developed in order to link the physical properties of galaxies to the dark matter haloes in which they reside. In this review, I…
Unsolved Problems about Supernovae
Nino Panagia
A number of unsolved problems and open questions about the nature and the properties of supernovae are identified and briefly discussed. Some suggestions and directions toward poss…
Early metal enrichment in high-redshift quasars
R. Maiolino
Quasars are powerful systems whose spectrum is rich of metal features that allow us to investigate the chemical evolution of galaxies at very high redshift, even close to the reion…
The End of Amnesia: Measuring the Metallicities of Type Ia SN Progenitors with Manganese Lines in Supernova Remnants
Carles Badenes, Eduardo Bravo, John P. Hughes
The Mn to Cr mass ratio in supernova ejecta has recently been proposed as a tracer of Type Ia SN progenitor metallicity. We review the advantages and problems of this observable qu…
