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 MaNGA: Stellar initial mass function variation inferred from Bayesian analysis of the integral field spectroscopy of early type galaxies
Shuang Zhou, H. J. Mo, Cheng Li +7
We analyze the stellar initial mass functions (IMF) of a large sample of early type galaxies (ETGs) provided by MaNGA. The large number of IFU spectra of individual galaxies provid…
SDSS-IV MaNGA: The Formation Sequence of S0 Galaxies
Amelia Fraser-McKelvie, Alfonso Aragón-Salamanca, Michael Merrifield +5
Gas stripping of spiral galaxies or mergers are thought to be the formation mechanisms of lenticular galaxies. In order to determine the conditions in which each scenario dominates…
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…
SDSS-IV MaNGA: Modelling the metallicity gradients of gas and stars - radially dependent metal outflow vs IMF
Jianhui Lian, Daniel Thomas, Claudia Maraston +7
In our previous work, we found that only two scenarios are capable of reproducing the observed integrated mass-metallicity relations for the gas and stellar components of local sta…
