The Transverse Proximity Effect in Spectral Hardness
We report on our recent detection of the transverse proximity effect of 4 foreground quasars near Q 0302−003 (z = 3.285) as a local hardness fluctuation in the spectral shape of the intergalactic UV radiation field, found by correlating the H I Lyα absorption with the corresponding He II Lyα absorption. We argue that the spectral hardness is a sensitive physical measure to reveal the influence ...
متن کاملQuasars near the line of sight towards Q 0302 − 003 and the transverse proximity effect ⋆
We report the discovery of the faint (V ≃ 21.7) quasar QSO 03027−0010 at z = 2.808 in the vicinity of Q 0302−003, one of the few quasars observed with STIS to study intergalactic He absorption. Together with another newly discovered QSO at z = 2.29, there are now 6 QSOs known near the line of sight towards Q 0302−003, of which 4 are located within the redshift region 2.76 < ∼ z < ∼ 3.28 cove...
متن کاملCaught in the act : a helium - reionizing quasar near the line of sight to Q 0302 − 003 ?
We report the discovery of a quasar at z = 3.050 ± 0.003, closely coincident in redshift with the isolated low-opacity feature seen near z 3.056 in the otherwise black portion of the He Gunn-Peterson absorption trough seen toward the z = 3.286 background quasar Q0302−003, located 6. 5 away on the sky. We explore plausible models for the He ionization zone created by this neighboring quas...
