Spectrum of Virgo intracluster HII region
Emission line spectrum (in the visible/near-IR spectral region) of the compact HII region in the Virgo intracluster field, as obtained with the FORS2 multi-mode instrument of the 8.2-m VLT YEPUN telescope on Paranal. Emission lines from oxygen ([OIII]) and hydrogen (H-alpha, H-beta, H-gamma) atoms as well as ionized sulphur ([SII], [SIII]) are identified.
