APOGEE Chemical Abundances of Globular Cluster Giants in the Inner Galaxy
Ricardo P. Schiavon, Jennifer A. Johnson, Peter M. Frinchaboy +27
We report chemical abundances obtained by SDSS-III/APOGEE for giant stars in five globular clusters located within 2.2 kpc of the Galactic centre. We detect the presence of multipl…
SDSS-IV MaNGA: Properties of galaxies with kinematically decoupled stellar and gaseous components
Yifei Jin, Yanmei Chen, Yong Shi +30
We study the properties of 66 galaxies with kinematically misaligned gas and stars from MaNGA survey. The fraction of kinematically misaligned galaxies varies with galaxy physical…
SDSS IV MaNGA: The global and local stellar mass assemby histories of galaxies
Héctor J. Ibarra-Medel, Sebastián F. Sánchez, Vladimir Avila-Reese +10
By means of the fossil record method implemented through Pipe3D, we reconstruct the global and radial stellar mass growth histories (MGHs) of an unprecedentedly large sample of gal…
Do galaxy global relationships emerge from local ones? The SDSS IV MaNGA surface mass density-metallicity relation
Jorge K. Barrera-Ballesteros, Timothy M. Heckman, Guangtun B. Zhu +12
We present the stellar surface mass density {\it vs.} gas metallicity () relation for more than 500,000 spatially-resolved star-forming resolution elements (spaxels) from a…
SDSS-IV MaNGA: Faint quenched galaxies I- Sample selection and evidence for environmental quenching
Samantha J. Penny, Karen L. Masters, Anne-Marie Weijmans +21
Using kinematic maps from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we reveal that the majority of low-mass quenched g…
The Sloan Digital Sky Survey Quasar Catalog: twelfth data release
Isabelle Pâris, Patrick Petitjean, Nicholas P. Ross +43
We present the Data Release 12 Quasar catalog (DR12Q) from the Baryon Oscillation Spectroscopic Survey (BOSS) of the SDSS-III. This catalog includes all SDSS-III/BOSS objects that…
