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…
Both starvation and outflows drive galaxy quenching
James Trussler, Roberto Maiolino, Claudia Maraston +4
Star-forming galaxies can in principle be transformed into passive systems by a multitude of processes that quench star formation, such as the halting of gas accretion (starvation)…
Modelling the mass-metallicity relation of star-forming galaxies from z ~ 3.5 to z ~ 0
Jianhui Lian, Daniel Thomas, Claudia Maraston
We study the origin and cosmic evolution of the mass-metallicity relation (MZR) in star-forming galaxies based on a full, numerical chemical evolution model. The model was designed…
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…
