The sixteenth and final eBOSS data release (SDSS DR16) contains all data from eBOSS and its predecessor, the Baryonic Oscillation Spectroscopic Survey (BOSS), providing $210,005$ quasars with $z_{q}>2.10$ that are used to measure Ly$\alpha$ absorption. We measure the BAO scale both in...
We combine Gaia DR1, PS1, SDSS and 2MASS astrometry to measure proper motions for 350 million sources across three-fourths of the sky down to a magnitude of $m_r\\sim20$\\,. Using positions of galaxies from PS1, we build a common referen... HJ Tian,P Gupta,B Sesar,... 被引量...
Here we markedly expand this approach by cross-correlating SDSS DR7 and GALEX GR4+5 to catalog 428 SDSS and 165 other quasars with z > 2.78 having likely (~70%) GALEX detections, suggesting they are bright into the far-UV. Reconnaissance HST Cycle 16 Supplemental prism data for 29 of...
We measure the baryon acoustic oscillation (BAO) observables , , and as a function of red shift z in the range 0.1 to 0.7 with Sloan Digital Sky Survey (SDSS) data release DR13. These observables are independent and satisfy a consistency relation that pr

As seen in Figure 1, the entire DR of Mata Sul is part of the study area, as well as a good part of Agreste Central and Agreste Setentrional. These last 2 DRs have, respectively, 88.46% and 73.68% of their municipalities within the area of the basins studied. On the other hand, ...
Methods Preparation of LMW Aβ40 and Aβ42. Aβ peptides of 40 and 42 residues, Aβ 40 and Aβ 42, were synthesized and purified by Dr. James I. Elliott (New Haven). LMW Aβ 40 and Aβ 42 preparations were obtained using Size-Exclusion Chromatography (SEC). Aβ...
We analyze the cross-correlation of Mg II (λ2796, 2803) quasar absorption systems with luminous red galaxies (LRGs) from the Fifth Data Release (DR5) of the Sloan Digital Sky Survey. The absorption line sample consists of 2705 unambiguously intervening Mg II absorption systems, detected at ...
Cross identification between X-ray and Optical Clusters of Galaxies in the SDSS DR7 Field We use the ROSAT all sky survey X-ray cluster catalogs and the optical SDSS DR7 galaxy and group catalogs to cross-identify X-ray clusters with their optic... L Wang,X Yang,W Luo,... - 《Phy...
The spatial orientations of 142,929 SDSS DR-13, zmagnitude galaxies having red shift 0.50 to 0.53 have been analyzed. The main goal of this work is to examine the orientation of the angular momentum of galaxies within the given redshift limit in the framework of three different scenarios '...
