Low-z intergalactic medium. III.
Listed in IVOA Registry (Virtual Observatory)
We conduct an ultraviolet (HST and FUSE) spectroscopic survey of HI (Lyman lines) and seven metal ions (OVI, NV, CIV, CIII, SiIV, SiIII, FeIII) in the low-redshift IGM at z<0.4.
Description
We analyzed 650 Ly{alpha} absorbers over redshift path length {Delta}z=5.27, detecting numerous absorbers: 83 OVI systems, 39 CIII, 53 SiIII, 24 CIV, 24 NV, and so on. In the low-z IGM, we have accounted for ~40% of the baryons: 30% in the photoionized Ly{alpha} forest and 10% in the (T=10^5^-10^6^) WHIM traced by OVI.
Statistical metallicities are consistent with the canonical value of 10% solar, with considerable scatter.
