SDSS-IV MANGA: Spatially Resolved Star Formation Main Sequence and LI(N)ER Sequence
B. C. Hsieh, Lihwai Lin, J. H. Lin +17
We present our study on the spatially resolved H_alpha and M_star relation for 536 star-forming and 424 quiescent galaxies taken from the MaNGA survey. We show that the star format…
SDSS-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Gail Zasowski, Hans-Walter Rix +47
SDSS-V will be an all-sky, multi-epoch spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way, trace the emergence of the chemical…
Stellar population properties for 2 million galaxies from SDSS DR14 and DEEP2 DR4 from full spectral fitting
Johan Comparat, Claudia Maraston, Daniel Goddard +13
We determine the stellar population properties - age, metallicity, dust reddening, stellar mass and the star formation history - for all spectra classified as galaxies that were pu…
The Sloan Digital Sky Survey Reverberation Mapping Project: H and H Reverberation Measurements From First-year Spectroscopy and Photometry
C. J. Grier, J. R. Trump, Yue Shen +39
We present reverberation mapping results from the first year of combined spectroscopic and photometric observations of the Sloan Digital Sky Survey Reverberation Mapping Project. W…
The Sloan Lens ACS Survey. XIII. Discovery of 40 New Galaxy-Scale Strong Lenses
Yiping Shu, Joel R. Brownstein, Adam S. Bolton +8
We present the full sample of 118 galaxy-scale strong-lens candidates in the Sloan Lens ACS (SLACS) Survey for the Masses (S4TM) Survey, which are spectroscopically selected from t…
SDSS IV MaNGA - sSFR profiles and the slow quenching of discs in green valley galaxies
Francesco Belfiore, Roberto Maiolino, Kevin Bundy +11
We study radial profiles in H equivalent width and specific star formation rate (sSFR) derived from spatially-resolved SDSS-IV MaNGA spectroscopy to gain insight on the physical…
SDSS-IV MaNGA: The Different Quenching Histories of Fast and Slow Rotators
Rebecca Smethurst, Karen Masters, Chris Lintott +9
Do the theorised different formation mechanisms of fast and slow rotators produce an observable difference in their star formation histories? To study this we identify quenching sl…
SSDSS IV MaNGA - Properties of AGN host galaxies
S. F. Sanchez, V. Avila-Reese, H. Hernandez-Toledo +22
We present here the characterization of the main properties of a sample of 98 AGN host galaxies, both type-II and type-I, in comparison with those of about 2700 non-active galaxies…
The BOSS Emission-Line Lens Survey V. Morphology and Substructure of Lensed Lyman- Emitters at redshift in the BELLS GALLERY
Matthew Cornachione, Adam Bolton, Yiping Shu +9
We present a morphological study of the 17 lensed Lyman- emitter (LAE) galaxies of the Baryon Oscillation Spectroscopic Survey Emission-Line Lens Survey (BELLS) for the GALaxy-L…
Probing the kinematic morphology-density relation of early-type galaxies with MaNGA
J. E. Greene, A. Leauthaud, E. Emsellem +17
The "kinematic" morphology-density relation for early-type galaxies posits that those galaxies with low angular momentum are preferentially found in the highest-density regions of…
The SDSS-IV MaNGA Sample: Design, Optimization, and Usage Considerations
David A. Wake, Kevin Bundy, Aleksandar M. Diamond-Stanic +15
We describe the sample design for the SDSS-IV MaNGA survey and present the final properties of the main samples along with important considerations for using these samples for scie…
The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment
Bela Abolfathi, D. S. Aguado, Gabriela Aguilar +344
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourtee…
Discovery of a Very Bright and Intrinsically Very Luminous, Strongly Lensed Lyα Emitting Galaxy at z = 2.82 in the BOSS Emission-Line Lens Survey
Rui Marques-Chaves, Ismael Pérez-Fournon, Yiping Shu +9
We report the discovery of a very bright (r = 20.16), highly magnified, and yet intrinsically very luminous Lyα emitter (LAE) at z = 2.82. This system comprises four images in the…
SDSS-IV MaNGA: The Impact of Diffuse Ionized Gas on Emission-line Ratios, Interpretation of Diagnostic Diagrams, and Gas Metallicity Measurements
Kai Zhang, Renbin Yan, Kevin Bundy +24
Diffuse Ionized Gas (DIG) is prevalent in star-forming galaxies. Using a sample of 365 nearly face-on star-forming galaxies observed by MaNGA, we demonstrate how DIG in star-formin…
