چکیده
The two-point correlation function, , of Lyman-forest is found to be large, = 1:8 +1:6 ?1:2 , > 90% conndence level, on the scale of 250-500 km/s for a sample of absorbers (0 < z < 1:3) assembled from HST Key Project Observations. This correlation function is stronger than at high redshift (z > 1:7) where 0:2 for velocities > 250 km/s.

Strong Clustering in the Low Redshift Lyman-α Forest
The two-point correlation function, ξ, of Lyman-α forest is found to be large, ξ = 1.8 −1.2, > 90% confidence level, on the scale of 250-500 km/s for a sample of absorbers (0 < z < 1.3) assembled from HST Key Project Observations. This correlation function is stronger than at high redshift (z > 1.7) where ξ ≈ 0.2 for velocities > 250 km/s. Subject headings: quasars: absorption lines
متن کاملThe Clustering of High Redshift Galaxies in the Cold Dark Matter Scenario
We investigate the clustering of high redshift galaxies in five variants of the cold dark matter (CDM) scenario, using hydrodynamic cosmological simulations that resolve the formation of systems with circular velocities vc ≥ 100 km s −1 (Ω = 1) or vc ≥ 70 km s −1 (Ω = 0.4). Although the five models differ in their cosmological parameters and in the shapes and amplitudes of their mass power spec...
متن کاملA high - resolution study of the evolution of the Lyman α forest in the redshift interval 0 . 9 < z < 1 . 7 ⋆
A high-resolution study of the evolution of the Lyman α forest in the redshift interval 0.9 < z < 1.7 Abstract. Spectroscopy with HST/STIS Echelle and VLT/UVES of the bright QSO HE 0515−4414 (zem = 1.73, B = 15.0) offers for the first time the opportunity to study the Lyman α forest in the redshift range 0.9 < z < 1.7 at a resolution ≤ 10 km s −1. The number density evolution of the Lyman α lin...
متن کاملFirst Investigation of the Clustering Environment of Damped Lyman Α Absorbers at Z ≃
We report the first observations of the clustering environment of damped Lyman α absorption systems at z ≃ 4. Color selection and photometric redshifts were used to select 44 candidate Lyman-break galaxies brighter than IAB = 25.5 from deep BRI images of the 35 arcmin 2 field containing the quasar BR 0951−04. Multislit spectroscopy of 35 candidate galaxies was performed and 8 of these candidate...
متن کاملThe Abundance of Low-luminosity Lyman Α Emitters at High Redshift
We derive the luminosity function of high-redshift Lyman α emitting sources from a deep, blind, spectroscopic survey that utilized strong-lensing magnification by intermediate-redshift clusters of galaxies. We observed carefully selected regions near 9 clusters, consistent with magnification factors generally greater than 10 for the redshift range 4.5< z <6.7. Eleven emission-line candidates we...
