Mapping Dust Attenuation at Kiloparsec Scales. III. The 2175Ã Bump
Ruonan Guo, Cheng Li, Tao Jing +3
We combine the SwiM_v4.2 Swift/UVOT+MaNGA catalog with 2MASS imaging to map the 2175Ã 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
The paper models kiloparsec‑scale dust attenuation in nearby galaxies using uniform‑screen silicate and graphite grain mixtures to link observed attenuation curves to effective dus…
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
VÃctor 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…
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…
