Molecular hydrogen in damped Ly-alpha systems: clues to interstellar physics at high-redshift
H. Hirashita, A. Ferrara
In order to interpret H2 (molecular hydrogen) quasar absorption line observations of damped Ly-alpha systems (DLAs) and sub-DLAs, we model their H2 abundance as a function of dust-…

Effects of dust grains on early galaxy evolution
H. Hirashita, A. Ferrara
Stars form out of molecular gas and supply dust grains during their last evolutionary stages; in turn hydrogen molecules (H2) are produced more efficiently on dust grains. Therefor…

Dust and hydrogen molecules in the extremely metal-poor dwarf galaxy SBS 0335-052
H. Hirashita, L. K. Hunt, A. Ferrara
During the early stages of galaxy evolution, the metallicity is generally low and nearby metal-poor star-forming galaxies may provide templates for primordial star formation. In pa…
