Evidence for Variability of Intervening Absorption Lines toward GRB 060206 : Implications for the Mg II Incidence Problem
We examine variability of absorption line strength of intervening systems along the line of sight to GRB 060206 at z=4.05, by the low-resolution optical spectra obtained by the Subaru telescope from six to ten hours after the burst. Strong variabilities of Fe II and Mg II lines at z = 1.48 during t =5–8 hours have been reported for this GRB (Hao et al. 2007), and this has been used to support t...
متن کاملNo Evidence for Variability of Intervening Absorption Lines toward GRB 060206 : Implications for the Mg II Incidence Problem ∗
We examine variability of absorption line strength of intervening systems along the line of sight to GRB 060206 at z = 4.05, by the low-resolution optical spectra obtained by the Subaru telescope from six to ten hours after the burst. Although strong variabilities of Fe II and Mg II lines at z = 1.48 during t=5–8 hours have been reported for this GRB (Hao et al. 2007), our spectra with higher s...
متن کاملOBSERVATIONS OF Mg II ABSORPTION NEAR z ∼ 1 GALAXIES SELECTED FROM THE DEEP2 REDSHIFT SURVEY
We study the frequency of Mg II absorption in the outer haloes of galaxies at z = 0.6 − 1.4 (with median z = 0.87), using new spectra obtained of ten background quasars with galaxy impact parameters of b < 100 kpc. The quasar sightlines were selected from the SDSS DR6 QSO catalog based on proximity to galaxies in the DEEP2 redshift survey. In addition to the 10 small impact systems, we examine ...
متن کاملUltraviolet Fe II emission in z ∼ 2 quasars
We present spectra of six luminous quasars at z ∼ 2, covering rest wavelengths 1600−3200 Å. The fluxes of the UV Fe II emission lines and Mg II λ2798 doublet, the line widths of Mg II, and the 3000 Å luminosity were obtained from the spectra. These quantities were compared with those of low-redshift quasars at z = 0.06−0.55 studied by Tsuzuki et al. In a plot of the Fe II(UV)/Mg II flux ratio a...
متن کاملA SURVEY OF Mg II ABSORPTION AT 2 < z < 6 WITH MAGELLAN / FIRE . I . SAMPLE AND EVOLUTION OF THE Mg II FREQUENCY
We present initial results from the first systematic survey for Mg ii quasar absorption lines at z > 2.5. Using infrared spectra of 46 high-redshift quasars, we discovered 111 Mg ii systems over a path covering 1.9 < z < 6.3. Five systems have z > 5, with a maximum of z = 5.33—the most distant Mg ii system now known. The comoving Mg ii line density for weaker systems (Wr < 1.0Å) is statisticall...
