The contribution of UVES@VLT to the new era of QSO absorption line studies
Valentina D'Odorico, Miroslava Dessauges-Zavadsky
We briefly review the main results obtained in the field of QSO absorption line studies with the UVES high resolution spectrograph mounted on the Kueyen unit of the ESO Very Large…
CODEX/ESPRESSO: the era of precision spectroscopy
Valentina D'Odorico
CODEX is a high resolution spectrograph for the European ELT. CODEX is conceived to reach the highest precision and stability, allowing the execution of programs spanning many year…
A cold metal-poor cloud traced by a weak MgII absorption at z~0.45. First detection of SiI, CaI and FeI in a QSO absorber
Valentina D'Odorico
We present the observations of a weak MgII absorption system detected at z~0.452 in the UVES high resolution spectrum of the QSO HE0001-2340. The weaker of the two MgII components…
Ly-alpha forest: efficient unbiased estimation of second-order properties with missing data
R. Vio, V. D'Odorico, H. Stoyan +1
Context. One important step in the statistical analysis of the Ly-alpha forest data is the study of their second order properties. Usually, this is accomplished by means of the two…
Hints of star fomation at z>6: the chemical abundances of the DLA system in the QSO BRI 1202-0725 (z_abs = 4.383)
Valentina D'Odorico, Paolo Molaro
The Damped Ly-alpha (DLA) absorber at redshift z_abs=4.383 observed toward QSO BRI 1202-0725 is studied by means of high resolution (FWHM ~ 7 km/s) VLT-UVES spectra. We refine a pr…
The size and geometry of the Ly_alpha clouds
V. D'Odorico, S. Cristiani, S. D'Odorico +3
Spectra of the QSO pair Q0307-195A,B have been obtained in the Ly-alpha Forest (3660 - 3930 A) and C IV (4720 - 4850 A) regions with a FWHM resolution between 0.7 and 0.5 A. 46 lin…
The clustering properties of the Lyman-alpha clouds
S. Cristiani, S. D'Odorico, V. D'Odorico +3
We analyze the clustering properties of a high-resolution (~10 km/s) sample of about 1600 Lyman-alpha lines in the spectra of 15 quasars, obtained in the framework of an ESO key-pr…
