Stellar population models based on the SDSS-IV MaStar library of stellar spectra – I. Intermediate-age/old models Open

Claudia Maraston, Lewis Hill, D. Thomas, Renbin Yan, Yuca C Chen , et al. · 2020

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 wavelength range 0.36–1.03 µm and share the same spect…

SDSS-IV MaStar: A Large and Comprehensive Empirical Stellar Spectral Library—First Release Open

Renbin Yan, Yanping Chen, Daniel Lazarz, Dmitry Bizyaev, Claudia Maraston , et al. · 2019

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 3622–10354 Å at a resolving power of R ∼ 1800. The spectra were obtained us…

Stellar population properties for 2 million galaxies from SDSS DR14 and DEEP2 DR4 from full spectral fitting Open

Johan Comparat, Claudia Maraston, Daniel Goddard, Violeta González-Pérez, Jianhui Lian , et al. · 2019

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 published by the Sloan Digital Sky Survey (SDSS data release …

SDSS-IV MaNGA: local and global chemical abundance patterns in early-type galaxies Open

Taniya Parikh, D. Thomas, Claudia Maraston, Kyle B. Westfall, Jianhui Lian , et al. · 2018

Chemical enrichment signatures strongly constrain galaxy formation and\nevolution, and a detailed understanding of abundance patterns provides clues\nregarding the nucleosynthetic production pathways of elements. Using the\nSDSS-IV MaNGA I…

SDSS-IV MaNGA: the spatially resolved stellar initial mass function in ∼400 early-type galaxies Open

Taniya Parikh, D. Thomas, Claudia Maraston, Kyle B. Westfall, Daniel Goddard , et al. · 2018

MaNGA provides the opportunity to make precise spatially resolved\nmeasurements of the IMF slope in galaxies owing to its unique combination of\nspatial resolution, wavelength coverage and sample size. We derive radial\ngradients in age, e…

Stellar population properties for 2 million galaxies from SDSS DR14 and\n DEEP2 DR4 from full spectral fitting Open

Johan Comparat, Claudia Maraston, Daniel Goddard, Violeta González-Pérez, Jianhui Lian , et al. · 2017

We determine the stellar population properties - age, metallicity, dust\nreddening, stellar mass and the star formation history - for all spectra\nclassified as galaxies that were published by the Sloan Digital Sky Survey\n(SDSS data relea…

Carbon stars in the X-Shooter Spectral Library Open

A. Gonneau, A. Lançon, S. C. Trager, B. Aringer, M. Lyubenova , et al. · 2016

We provide a new collection of spectra of 35 carbon stars obtained with the\nESO/VLT X-shooter instrument as part of the X-shooter Spectral Library project.\nThe spectra extend from 0.3$\\mu$m to 2.4$\\mu$m with a resolving power above\n$\…

Single stellar populations in the near-infrared Open

S. Meneses-Goytia, R. F. Peletier, S. C. Trager, A. Vazdekis · 2015

\n We present a detailed study of the stars of the NASA InfraRed Telescope Facility (IRTF) spectral library to understand its full extent and reliability for use with stellar population (SP) modeling. The library consist of 210 stars, with…

Single Stellar Populations in the Near-Infrared - I. Preparation of the IRTF spectral stellar library Open

S. Meneses-Goytia, R. F. Peletier, S. C. Trager, J. Falcón‐Barroso, M. Koleva , et al. · 2015

We present a detailed study of the stars of the IRTF spectral library to understand its full extent and reliability for use with Stellar Population (SP) modeling. The library consist of 210 stars, with a total of 292 spectra, covering the …

Stellar population models in the Near-Infrared Open

S. Meneses-Goytia · 2015

The study of early-type elliptical and lenticular galaxies provides important information about the formation and evolution of galaxies in the early Universe. These distant systems cannot be studied by looking at their individual stars but…
