SDSS-IV MaNGA: environmental dependence of stellar age and metallicity gradients in nearby galaxies
Zheng Zheng, Huiyuan Wang, Junqiang Ge +20
We present a study on the stellar age and metallicity distributions for 1105 galaxies using the STARLIGHT software on MaNGA integral field spectra. We derive age and metallicity gr…
SDSS-IV MaNGA: A serendipitous observation of a potential gas accretion event
Edmond Cheung, David V. Stark, Song Huang +24
The nature of warm, ionized gas outside of galaxies may illuminate several key galaxy evolutionary processes. A serendipitous observation by the MaNGA survey has revealed a large,…
SDSS IV MaNGA - The spatially resolved transition from star formation to quiescence
Francesco Belfiore, Roberto Maiolino, Claudia Maraston +19
Using spatially resolved spectroscopy from SDSS-IV MaNGA we have demonstrated that low ionisation emission line regions (LIERs) in local galaxies result from photoionisation by hot…
SEGUE: A Spectroscopic Survey of 240,000 stars with g=14-20
II SEGUE Collaboration, Brian Yanny, Constance Rockosi +2
The SEGUE survey obtained 240,000 moderate resolution (R = 1800) spectra from 3900 - 9000 Angstroms of fainter Milky Way stars (14.0 < g < 20.3) of a wide variety of spectral types…
