Estimating dust attenuation from galactic spectra. II. Stellar and gas attenuation in star-forming and diffuse ionized gas regions in MaNGA
Niu Li, Cheng Li, Houjun Mo +7
We investigate the dust attenuation in both stellar populations and ionized gas in kpc-scale regions in nearby galaxies, using integral field spectroscopy data from MaNGA MPL-9. We…
A new estimator of resolved molecular gas in nearby galaxies
Ryan Chown, Cheng Li, Laura C. Parker +3
A relationship between dust-reprocessed light from recent star formation and the amount of star-forming gas in a galaxy produces a correlation between WISE 12 m emission and CO…
Estimating dust attenuation from galactic spectra. I. methodology and tests
Niu Li, Cheng Li, Houjun Mo +3
We develop a method to estimate the dust attenuation curve of galaxies from full spectral fitting of their optical spectra. Motivated from previous studies, we separate the small-s…
Wolf-Rayet galaxies in SDSS-IV MaNGA. I. Catalog construction and sample properties
Fu-Heng Liang, Cheng Li, Niu Li +5
Wolf-Rayet (WR) galaxies are a rare population of galaxies that host living high-mass stars during their WR phase (i.e. WR stars) and are thus expected to provide interesting const…
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…
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…
