Stellar population models based on the SDSS-IV MaStar library of stellar spectra. I. Intermediate-age/old models
C. Maraston, L. Hill, D. Thomas +14
We use the first release of the SDSS/MaStar stellar library comprising ~9000, high S/N spectra, to calculate integrated spectra of stellar population models. The models extend over…
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
SDSS-IV MaNGA: local and global chemical abundance patterns in early-type galaxies
Taniya Parikh, Daniel Thomas, Claudia Maraston +6
Chemical enrichment signatures strongly constrain galaxy formation and evolution, and a detailed understanding of abundance patterns provides clues regarding the nucleosynthetic pr…
SDSS-IV MaStar -- A Large and Comprehensive Empirical Stellar Spectral Library: First Release
Renbin Yan, Yanping Chen, Daniel Lazarz +45
We present the first release of the MaNGA Stellar Library (MaStar), which is a large, well-calibrated, high-quality empirical library covering the wavelength range of 3,622-10,354A…
SDSS-IV MaNGA: The Spatially Resolved Stellar Initial Mass Function in 400 Early-Type Galaxies
Taniya Parikh, Daniel Thomas, Claudia Maraston +20
MaNGA provides the opportunity to make precise spatially resolved measurements of the IMF slope in galaxies owing to its unique combination of spatial resolution, wavelength covera…
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…
