THE ELEVENTH AND TWELFTH DATA RELEASES OF THE SLOAN DIGITAL SKY SURVEY: FINAL DATA FROM SDSS-III
- S. Alam, F. D. Albareti, Key Laboratory of Optical Astronomy
- Physics
- 5 January 2015
The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical…
THE NINTH DATA RELEASE OF THE SLOAN DIGITAL SKY SURVEY: FIRST SPECTROSCOPIC DATA FROM THE SDSS-III BARYON OSCILLATION SPECTROSCOPIC SURVEY
- Christopher P. Ahn, R. Alexandroff, J. Zinn
- Physics
- 30 July 2012
The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS project includes…
ERRATUM: “THE EIGHTH DATA RELEASE OF THE SLOAN DIGITAL SKY SURVEY: FIRST DATA FROM SDSS-III” (2011, ApJS, 193, 29)
- SDSS-III collaboration Hiroaki Aihara, C. Prieto, I. Zehavi
- Geology
- 8 January 2011
Section 3.5 of Aihara et al. (2011) described various sources of systematic error in the astrometry of the imaging data of the Sloan Digital Sky Survey (SDSS). In addition to these sources of error,…
Measuring the galaxy–mass and galaxy–dust correlations through magnification and reddening
- B. M'enard, R. Scranton, M. Fukugita, G. Richards
- Physics
- 25 February 2009
We present a simultaneous detection of gravitational magnification and dust reddening effects due to galactic haloes and large-scale structure. The measurement is based on correlating the brightness…
The Giant Gemini GMOS survey of zem > 4.4 quasars – I. Measuring the mean free path across cosmic time
- G. Worseck, J. Prochaska, M. Fumagalli
- Physics
- 17 February 2014
We have obtained spectra of 163 quasars at zem > 4.4 with the Gemini Multi Object Spectrometers, the largest publicly available sample of high-quality, low-resolution spectra at these redshifts. From…
THE JHU-SDSS METAL ABSORPTION LINE CATALOG: REDSHIFT EVOLUTION AND PROPERTIES OF Mg ii ABSORBERS
- G. Zhu, B. M'enard
- Physics
- 27 November 2012
We present a generic and fully automatic method aimed at detecting absorption lines in the spectra of astronomical objects. The algorithm estimates the source continuum flux using a dimensionality…
Very weak lensing in the CFHTLS Wide: Cosmology from cosmic shear in the linear regime
- L. Fu, E. Semboloni, B. M'enard
- Physics
- 6 December 2007
Aims. We present an exploration of weak lensing by large-scale structure in the linear regime, using the third-year (T0003) CFHTLS Wide data release. Our results place tight constraints on the…
On the H I content, dust-to-gas ratio and nature of Mg II absorbers
- B. M'enard, D. Chelouche
- Physics
- 6 March 2008
We estimate the mean dust-to-gas ratio of Mg ii absorbers as a function of rest equivalent width W0 and redshift over the range 0.5 < z < 1.4. Using the expanded Sloan Digital Sky Survey/Hubble Space…
LOW-IONIZATION LINE EMISSION FROM A STARBURST GALAXY: A NEW PROBE OF A GALACTIC-SCALE OUTFLOW
- K. Rubin, J. Prochaska, A. Phillips
- Physics
- 19 August 2010
We study the kinematically narrow, low-ionization line emission from a bright, starburst galaxy at z = 0.69 using slit spectroscopy obtained with Keck/LRIS. The spectrum reveals strong absorption in…
Lensing, reddening and extinction effects of Mg ii absorbers from z= 0.4 to 2
- B. M'enard, D. Nestor, Ias
- Physics
- 7 June 2007
Using a sample of almost 7000 strong Mg II absorbers with W 0 > 1 A and 0.4 < z < 2.2 detected in the SDSS DR4 data set, we investigate the gravitational lensing and dust extinction effects they…
