Physical properties and small-scale structure of the Lyman-alpha forest: Inversion of the HE 1122-1628 UVES spectrum
E. Rollinde, P. Petitjean, C. Pichon
We study the physical properties of the Lyman-alpha forest by applying the inversion method described by Pichon et al. (2001) to the high resolution and high S/N ratio spectrum of…
The density structure around quasars from optical depth statistics
E. Rollinde, R. Srianand, T. Theuns +2
We present a method for studying the proximity effect and the density structure around redshift z=2-3 quasars. It is based on the probability distribution of Lyman-alpha pixel opti…
Transverse and longitudinal correlation functions in the Intergalactic Medium from 32 close pairs of high-redshift quasars
F. Coppolani, P. Petitjean, F. Stoehr +6
We present the transverse flux correlation function of the Lyman-alpha forest in quasar absorption spectra at z~2.1 from VLT-FORS and VLT-UVES observations of a total of 32 pairs o…
Recovering the topology of the IGM at z~2
S. Caucci, S. Colombi, C. Pichon +3
We investigate how well the 3D density field of neutral hydrogen in the Intergalactic Medium (IGM) can be reconstructed using the Lyman-alpha absorptions observed along lines of si…
The BigBOSS Experiment
D. Schlegel, F. Abdalla, T. Abraham +138
BigBOSS is a Stage IV ground-based dark energy experiment to study baryon acoustic oscillations (BAO) and the growth of structure with a wide-area galaxy and quasar redshift survey…
Small scale structure in molecular gas from multi-epoch observations of HD 34078
E. Rollinde, P. Boisse, S. R. Federman +1
We present spectroscopic observations of the runaway reddened star HD 34078 acquired during the last three years at Observatoire de Haute Provence and McDonald Observatory as well…
