Galactic HII regions in LAMOST Medium-Resolution Spectroscopic Survey of Nebulae
Yunning Zhao, Wei Zhang, Lin Ma +10
Based on LAMOST Medium-Resolution Spectroscopic Survey of Nebulae (MRS-N) data and WISE Galactic HII region catalog, we construct a sample of 280 Galactic HII regions and candidate…
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…
Regression for Astronomical Data with Realistic Distributions, Errors and Non-linearity
Tao Jing, Cheng Li
We have developed a new regression technique, the maximum likelihood (ML)-based method and its variant, the KS-test based method, designed to obtain unbiased regression results fro…
