Resolved and Integrated Stellar Masses in the SDSS-IV/MaNGA Survey, Paper II: Applications of PCA-based stellar mass estimates
Zachary J. Pace, Christy Tremonti, Yanmei Chen +9
A galaxy's stellar mass is one of its most fundamental properties, but it remains challenging to measure reliably. With the advent of very large optical spectroscopic surveys, effi…
Resolved and Integrated Stellar Masses in the SDSS-IV/MaNGA Survey, Paper I: PCA spectral fitting & stellar mass-to-light ratio estimates
Zachary J. Pace, Christy Tremonti, Yanmei Chen +9
We present a method of fitting optical spectra of galaxies using a basis set of six vectors obtained from principal component analysis (PCA) of a library of synthetic spectra of 40…
FOBOS: A Next-Generation Spectroscopic Facility at the W. M. Keck Observatory
K. Bundy, K. Westfall, N. MacDonald +38
High-multiplex and deep spectroscopic follow-up of upcoming panoramic deep-imaging surveys like LSST, Euclid, and WFIRST is a widely recognized and increasingly urgent necessity. N…
Signatures of stellar accretion in MaNGA early-type galaxies
Grecco A. Oyarzun, Kevin Bundy, Kyle B. Westfall +10
The late assembly of massive galaxies is thought to be dominated by stellar accretion in their outskirts (beyond 2 effective radii Re) due to dry, minor galaxy mergers. We use obse…
The Data Analysis Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey: Emission-Line Modeling
Francesco Belfiore, Kyle B. Westfall, Adam Schaefer +12
SDSS-IV MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is the largest integral-field spectroscopy survey to date, aiming to observe a statistically representative samp…
The Data Analysis Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey: Overview
Kyle B. Westfall, Michele Cappellari, Matthew A. Bershady +28
Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) is acquiring integral-field spectroscopy for the largest sample of galaxies to date. By 2020, the MaNGA Survey --- one o…
