Exploring the intergalactic medium with VLT/UVES
S. Cristiani, S. Bianchi, S. D'Odorico +1
The remarkable efficiency of the UVES spectrograph at the VLT has made it possible to push high-resolution, high-S/N ground observations of the Ly-a forest down to z~1.5, gaining n…
Lyman Continuum Escape from Inhomogeneous ISM
B. Ciardi, S. Bianchi, A. Ferrara
We have studied the effects of gas density inhomogeneities on the escape of ionising Lyman continuum (Lyc) photons from Milky Way-type galaxies via 3D numerical simulations using t…
Exploring the Lyman Forest with VLT/UVES
S. Cristiani, S. Bianchi, S. D'Odorico +1
A sample of 8 QSOs with 1.7 < z_em < 3.7 has been observed with VLT/UVES at a typical resolution 45000 and S/N~40-50. Thanks to the two-arm design of the spectrograph, a remarkable…
The contribution of galaxies to the UV ionising background and the evolution of the Lyman forest
Simone Bianchi, Stefano Cristiani, Tae-Sun Kim
We have modelled the evolution of the number of Ly_alpha absorbers with redshift, resulting from the evolution of the ionising background and the Hubble expansion. The contribution…
