The clustering of Luminous Red Galaxies around Mg II absorbers
We study the cross-correlation between 212 Mg II quasar absorption systems and ∼ 20,000 Luminous Red Galaxies (LRGs) selected from the Sloan Digital Sky Survey Data Release 1 in the redshift range 0.46 z6 0.8. The Mg II systems were selected to have λλ2796 & 2803 rest-frame equivalent widths >1.0 Å and identifications confirmed by the Fe II λ2600 or Mg I λ2852 lines. Over comoving scales 0.05–1...
متن کاملThe Clustering of Galaxies around Quasars
We study the cross-correlation between quasars and galaxies by embedding models for the formation and evolution of the two populations in cosmological N-body simulations. We adopt the quasar evolution model of Kauffmann & Haehnelt (2000), in which supermassive black holes are formed and fuelled during major mergers. We define the “bias” parameter bQG as the ratio of the cross-correlation functi...
متن کاملThe dark matter haloes and host galaxies of Mg II absorbers at z ∼ 1
Strong foreground absorption features from singly ionized magnesium (Mg II) are commonly observed in the spectra of quasars and are presumed to probe a wide range of galactic environments. To date, measurements of the average dark matter (DM) halo masses of intervening Mg II absorbers by way of large-scale cross-correlations with luminous galaxies have been limited to z < 0.7. In this work, we ...
متن کاملThe distribution of neutral hydrogen around high-redshift galaxies and quasars in the EAGLE simulation
The observed high covering fractions of neutral hydrogen (H I) with column densities above ∼1017 cm−2 around Lyman-Break Galaxies (LBGs) and bright quasars at redshifts z ∼ 2–3 has been identified as a challenge for simulations of galaxy formation. We use the Evolution and Assembly of Galaxies and their Environment (EAGLE) cosmological, hydrodynamical simulation, which has been shown to reprodu...
متن کاملQuasars Probing Quasars Ii: the Anisotropic Clustering of Optically Thick Absorbers around Quasars
With close pairs of quasars at different redshifts, a background quasar sightline can be used to study a foreground quasar’s environment in absorption. We used a sample of 17 Lyman limit systems with column density NHI > 10 19 cm selected from 149 projected quasar pair sightlines, to investigate the clustering pattern of optically thick absorbers around luminous quasars at z ∼ 2.5. Specifically...
