Quasar-Lyman Forest Cross-Correlation from BOSS DR11 : Baryon Acoustic Oscillations
Andreu Font-Ribera, David Kirkby, Nicolas Busca +40
We measure the large-scale cross-correlation of quasars with the Lyman alpha forest absorption, using over 164,000 quasars from Data Release 11 of the SDSS-III Baryon Oscillation S…
The warm-hot intergalactic medium at z~2.2: Metal enrichment and ionization source
Jacqueline Bergeron, Bastien Aracil, Patrick Petitjean +1
Results are presented for our search for warm-hot gas towards the quasar Q 0329-385. We identify ten OVI systems of which two are within 5000 km/s of z_em and a third one should be…
The microwave background temperature at the redshift of 2.33771
R. Srianand, Patrick Petitjean, Cedric Ledoux
The Cosmic Microwave Background radiation is a fundamental prediction of Hot Big Bang cosmology. The temperature of its black-body spectrum has been measured at the present time, $…
Identification of absorbing galaxies towards the QSO J2233-606 in the Hubble Deep Field South
L. Tresse, M. Dennefeld, P. Petitjean +2
We present spectroscopic observations of galaxies lying within 1' from the QSO J2233-606 in the HDF-S. Several are found to be coincident in redshift with absorption line systems s…
Near infrared observations of quasars with extended ionized envelopes
I. Marquez, F. Durret, P. Petitjean
We have observed a sample of 15 and 8 quasars with redshifts between 0.11 and 0.87 (mean value 0.38) in the J and K' bands respectively. Eleven of the quasars were previously known…
