Ongoing, forthcoming, and next-generation observational projects will detect the first objects appearing at the end of the so-called dark ages, when reionization takes place and small-scale structures begin to form, settling the further shape of the universe we are familiar with. Thanks to the dramatic improvements of ground-based and space-borne instruments exploring the radio to gamma-ray wavelengths, which allow us to reach an unprecedented depth, as well as exploiting the so-called gravitational lensing telescopes, it will be possible to investigate the earliest, highest-redshift sources of light, draw an accurate picture of the reionization epoch as well as of the early stages (3 < z < 7) in the star formation history, and finally probe the cosmological conditions at that epoch. The first light objects allow us to investigate the cosmology at lower redshift, and finally investigate the role and the nature of dark matter and dark energy. Several challenges emerge for theoretical cosmology
- the formation and abundance of the first dark matter halos, in which the first shining objects presumably are located, does not seem to match the one predicted by the standard ΛCDM model and could therefore require primordial non-Gaussianities in the matter density field and/or a better understanding of the nature of dark matter;
- gamma-ray bursts might provide the most distant standard candles to investigate the geometry of the universe;
- owing to the degeneracy occurring in temperature and polarization spectra of the cosmic microwave background, the details of the reionization history might modify the interpretation of the dark energy;
- 21-cm brightness fluctuations occurring during the reionization epoch and detected with low-frequency radio experiments can be used to determine the statistical properties of density fluctuations in the early universe;
- Lyman-α forest in the spectra of high-redshift QSO as well as the absorption systems in the spectra of distant GRBs provide a powerful tool to investigate the temperature-density relation as well as the possible role of warm dark matter and dark energy at low redshift.
In the same spirit of the very successful, previous international meetings hosted at Marseille/LAM since 2008 (CosmoTools in 2008, CosmoClusters in 2009, CosmoZsurveys in 2010), Cosmo-First-Objects is intended to offer a pleasant ground to discuss about cosmology between redshift ∼3 and ∼20, spanning all of the astrophysical probes that are relevant for fundamental physics. As in the previous Cosmo- meeting editions, the greatest interaction between participants will be assured by alternating talks and several free and leaded discussions, including keynotes at the end of each day. With the purpose of fostering new ideas and collaborations, the major actors at the forefront of these fields are invited, and the attendance of students is highly encouraged. Aiming to offer an informal and productive ambience, the attendance is limited to 50 people. Financial aid shall be available, with priority to students and young post-doc and researcher.

financial aid : news hopefully coming soon - we're waiting for a final answer from other, contacted sponsors...
How to get to LAM: Marseille/Nice/Lyon airport, then shuttle/train (TGV) to Marseille. In particular:
Nice airport - Marseille ("St. Charles" railway station): train or shuttle
From Marseille ("St. Charles" railway station or downtown) to LAM (~25 min): metro line n.1 until terminus "La Rose - Technopole Château-Gombert", then bus line n.1 (on the right at the metro’s exit) till "I.M.T." stop, OAMP-LAM is the red-blue building; see the map.
Marseille airport - LAM by taxi: from 30 min to hours... (50-60 euro).
