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…

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…
