The high-redshift universe and cosmology at Arcetri
|
How cosmic structures formed and how galaxies were
assembled remain key open questions in the study of modern
cosmology.
Theoretical models of primordial star formation
and observations of faint high-redshift galaxy samples
are the cornerstone of our group.
By combining results from observational and theoretical research,
the ultimate aim is to constrain the epoch of structure
and galaxy formation,
and broaden our understanding of physical processes at work in
the early universe.
Specifically, our group is engaged in studies of:
-
Contribution of the first stars to cosmic reionization and
metal enrichment
(Antonella Maselli,
Raffaella Schneider)
-
Formation, evolution, and survival of dust grains in primordial
objects, and comparison of theoretical predictions and observations
(Simone Bianchi,
Raffaella Schneider,
Rosa Valiante)
-
Early-type galaxy scaling relations at high redshift
(Sperello di Serego Alighieri)
-
Mass-metallicity relation over cosmic epochs
