Mapping Dust Attenuation at Kiloparsec Scales. III. The 2175Å Bump
Ruonan Guo, Cheng Li, Tao Jing +3
We combine the SwiM_v4.2 Swift/UVOT+MaNGA catalog with 2MASS imaging to map the 2175Å attenuation bump at kiloparsec scales in nearby galaxies. We use two complementary estim…
Mapping Dust Attenuation at Kiloparsec Scales. IV. A Dust-model Interpretation of Attenuation Curves in Nearby Galaxies
Ruonan Guo, Cheng Li, Tao Jing +3
In this fourth paper on kiloparsec-scale dust attenuation, we ask whether the empirical trends found in Papers I--III can be translated into effective dust properties. Using attenu…
Contrasting evolutionary pathways of fast- and slow-rotating galaxies in the green valley
Shuang Zhou, Angela Iovino, Marcella Longhetti +2
We investigate the evolutionary pathways of green valley (GV) galaxies drawn from the SDSS-IV/MaNGA survey. The GV sample is divided into fast- and slow-rotating galaxies based on…
The imitation game (r)evolutions: -star effective shadow from GRMHD analysis
Víctor Jaramillo, Laura Meneses, Héctor R. Olivares Sánchez +3
-stars are a class of boson stars arising in scalar-field theories with interacting potentials, minimally coupled to gravity. We show that, in certain regions of parameter space…
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…
Testing a New Star Formation History Model from Principal Component Analysis to Facilitate Spectral Synthesis Modeling
Yanzhe Zhang, H. J. Mo, Katherine E. Whitaker +1
The spectrum of a galaxy is a complicated convolution of many properties of the galaxy, such as the star formation history (SFH), initial mass function, and metallicity. Inferring…
Two categories of UV-upturn galaxies revealed by semi-analytic models
Zhen Jiang, Cheng Li, Fenghui Zhang +1
UV-upturn galaxies are characterized by unusually excessive flux in the far-ultraviolet (FUV) band, observed in some elliptical galaxies and the bulges of disk galaxies. We examine…
The separate effect of halo mass and stellar mass on the evolution of massive disk galaxies
Shuang Zhou, Alfonso Aragón-Salamanca, Michael Merrifield
We analyse a sample of massive disk galaxies selected from the SDSS-IV/MaNGA survey to investigate how the evolution of these galaxies depends on their stellar and halo masses. We…
Where have all the low-metallicity galaxies gone? Tracing evolution in the mass--metallicity plane since a redshift of 0.7
Shuang Zhou, Alfonso Aragón-Salamanca, Michael Merrifield +1
Even over relatively recent epochs, galaxies have evolved significantly in their location in the mass-metallicity plane, which must be telling us something about the latter stages…
The IRX-Beta Relation in kpc-sized Star Forming Regions in Nearby Galaxies
Laura Duffy, Mallory Molina, Michael Eracleous +7
The effect of dust attenuation on a galaxy's light depends on a number of physical properties, such as geometry and dust composition, both of which can vary across the faces of gal…
Are Milky-Way-like galaxies like the Milky Way? A view from SDSS-IV/MaNGA
Shuang Zhou, Alfonso Aragón-Salamanca, Michael Merrifield +3
In this paper, we place the Milky Way (MW) in the context of similar-looking galaxies in terms of their star-formation and chemical evolution histories. We select a sample of 138 M…
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…
The impact of environment on the lives of disk galaxies as revealed by SDSS-IV MaNGA
Shuang Zhou, Michael Merrifield, Alfonso Aragón-Salamanca +4
Environment has long been known to have significant impact on the evolution of galaxies, but here we seek to quantify the subtler differences that might be found in disk galaxies,…
Semi-analytic spectral fitting: simultaneously modelling the mass accumulation and chemical evolution in MaNGA spiral galaxies
Shuang Zhou, Michael Merrifield, Alfonso Aragon-Salamanca
We develop a novel semi-analytic spectral fitting approach to quantify the star-formation histories (SFHs) and chemical enrichment histories (ChEHs) of individual galaxies. We cons…
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…
