The warm-hot intergalactic medium at z∼2.2: Metal enrichment and ionization source.

BERGERON J., ARACIL B., PETITJEAN P. and PICHON C.

Abstract (from CDS):

Result. are presented for our search for warm-hot gas towards the quasar Q 0329-385. We identify ten Ovi systems of which two are within 5000 km/s of zem and a third one should be of intrinsic origin. The seven remaining systems have Hi column densities 1013.7≤N(HI)≤1015.6cm–2. At least ∼1/3 of the individual Ovi sub-systems have temperatures T<1x105K and cannot originate in collisionally ionized gas. Photoionization by a hard UV background field reproduces well the ionic ratios for metallicities in the range 10–2.5-10–0.5 solar, with possibly sub-solar N/C relative abundance. For [O/C]=0, the sizes inferred for the Ovi clouds are in some cases larger than the maximum extent implied by the Hubble flow. This constraint is fulfilled assuming a moderate overabundance of oxygen relative to carbon. For a soft UV ionizing spectrum, an overabundance of O/C is required, [O/C]≃0.0-1.3. For a hard(soft) U spectrum and [O/C]=0(1), the Ovi regions have overdensities ρ/<ρ≥∼10-40.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
