Mapping Dust Attenuation at Kiloparsec Scales. II. Attenuation Curves from Near-Ultraviolet to Near-Infrared
Ruonan Guo, Cheng Li, Shuang Zhou +3
This is the second paper in a series that utilize IFS from MaNGA, NUV imaging from Swift/UVOT and NIR imaging from 2MASS to study dust attenuation properties on kpc scales in nearb…
Estimating Dust Attenuation From Galactic Spectra. III. Radial variations of dust attenuation scaling relations in MaNGA galaxies
Niu Li, Cheng Li
We investigate the radial dependence of the scaling relations of dust attenuation in nearby galaxies using integral field spectroscopy (IFS) data from MaNGA. We identify ionized ga…
Post-starburst galaxies in SDSS-IV MaNGA: Two broad categories of evolutionary pathways
Zhuo Cheng, Cheng Li, Niu Li +2
We study the size-mass relation (SMR) and recent star formation history (SFH) of post-starburst (PSB) galaxies in the local Universe, using spatially resolved spectroscopy from the…
Criss Cross Nebula: Case study of shock regions with resolved microstructures at scales of 1000 AU
Tao Jing, Cheng Li, Renbin Yan +7
Using integral field spectroscopy from MaNGA, we study the resolved microstructures in a shocked region in Criss Cross Nebula (CCN), with an unprecedentedly high resolution of $\le…
Mapping dust attenuation and the 2175 Å bump at kpc scales in nearby galaxies
Shuang Zhou, Cheng Li, Niu Li +8
We develop a novel approach to measure dust attenuation properties of galaxies, including the dust opacity, shape of the attenuation curve and the strength of the 2175Å absorption…
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…
Wolf-Rayet galaxies in SDSS-IV MaNGA. II. Metallicity dependence of the high-mass slope of the stellar initial mass function
Fu-Heng Liang, Cheng Li, Niu Li +4
As hosts of living high-mass stars, Wolf-Rayet (WR) regions or WR galaxies are ideal objects for constraining the high-mass end of the stellar initial mass function (IMF). We const…
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…
Linking bar- and interaction-driven molecular gas concentration with centrally-enhanced star formation in EDGE-CALIFA galaxies
Ryan Chown, Cheng Li, E. Athanassoula +6
We study the spatially resolved star formation history and molecular gas distribution of 58 nearby galaxies, using integral field spectroscopy from the CALIFA survey and CO $J=1\ri…
