Probing Gravitational Lensing of the CMB with SDSS-IV Quasars [PDF]
, 2019 We study the cross-correlation between the Planck CMB lensing convergence map and the eBOSS quasar overdensity obtained from the Sloan Digital Sky Survey (SDSS) IV, in the redshift range $0.9 < z < 2.2$. We detect the CMB lensing convergence-quasar cross

THE PAN-STARRS1 DISTANT z > 5.6 QUASAR SURVEY: MORE THAN 100 QUASARS WITHIN THE FIRST GYR OF THE UNIVERSE [PDF]
, 2016 Luminous quasars at can be studied in detail with the current generation of telescopes and provide us with unique information on the first gigayear of the universe. Thus far, these studies have been statistically limited by the number of quasars known at

Journal of Vinyl and Additive Technology, EarlyView.Adjusting extrusion variables are a key to balance the flame retardancy and mechanical properties of polyolefin/leather waste fiber composites. ABSTRACT The extrusion processing variables represent a key to the optimal use of additives and thus the development of flame‐retardant polymer composites. Adjusting the property profile, for example, finding a

The Color Variability of Quasars
, 2011 We quantify quasar color-variability using an unprecedented variability database - ugriz photometry of 9093 quasars from SDSS Stripe 82, observed over 8 years at ~60 epochs each. We confirm previous reports that quasars become bluer when brightening.

Understanding extreme quasar optical variability with CRTS – II. Changing-state quasars [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present the results of a systematic search for quasars in the Catalina Real-time Transient Survey exhibiting both strong photometric variability and spectroscopic variability over a decadal baseline. We identify 111 sources with specific patterns of

3D SR‐μXCT analysis for lithology detection: Application to Ryugu sample A0159
Meteoritics &Planetary Science, EarlyView.Abstract Extraterrestrial breccia samples are formed through impact‐related processes that combine the fragments of distinct lithologies. As such, they are valuable indicators of the complex formation and evolution history of planetesimals in our solar system.

An overview on the quasar redshifts
Revista Técnica de la Facultad de Ingeniería, 2011 An overview of the foundations of modem cosmology a well as the controversies about physical association between high-red shift quasi-stellar objects and low-red shift galaxies are presented. This kind of evidence challenges the current velocity-distance

On the Connection Between Metal Absorbers and Quasar Nebulae [PDF]
, 2007 We establish a simple model for the distribution of cold gas around L* galaxies using a large set of observational constraints on the properties of strong MgII absorber systems.

THE FINAL SDSS HIGH-REDSHIFT QUASAR SAMPLE OF 52 QUASARS AT z > 5.7 [PDF]
, 2016 We present the discovery of nine quasars at identified in the Sloan Digital Sky Survey (SDSS) imaging data. This completes our survey of quasars in the SDSS footprint.

Experimental Physiology, EarlyView.Abstract This study investigated the acute effects of two isoenergetic high‐intensity interval exercise (HIIE) sessions, running (HIIE‐RUN) and cycling (HIIE‐BIKE), on post‐exercise oxygen consumption (V̇O2${\dot V_{{{\mathrm{O}}_2}}}$), carbon dioxide production (V̇CO2${\dot V_{{\mathrm{C}}{{\mathrm{O}}_2}}}$), substrate oxidation and 24‐h energy ...
