Evolution of the Local Spiral Structure Revealed by OB-type Stars in Gaia DR3

open access: yesThe Astronomical Journal
The structure and evolution of the spiral arms of the Milky Way have long been an important yet controversial issue. The wide age range of OB-type stars, coupled with the large amount of high-precision astrometric data provided by Gaia DR3, presents us ...

The Link between Galaxy Structure Properties and Star Formation in Local Galaxies

open access: yesThe Astrophysical Journal
To investigate the role of morphology in galaxy evolution, we analyze the relationships between galaxy structure, star formation, and H i gas content.

Switchable Privacy Displays: Applications, Optical Measurements, and Evaluation With Focus on Automotive

open access: yesJournal of the Society for Information Display, EarlyView.
Switchable‐privacy displays can be used to protect sensitive data in public spaces and to avoid driver distraction on codriver displays. The key optical parameters are the luminance in public and privacy modes, measured over the viewing angle, and the image quality for the intended observers.

Stellar CoRGI in MaNGA: Stellar Counterrotating Galaxies Identified in the MaNGA Survey

open access: yesThe Astrophysical Journal Supplement Series
Stellar counterrotating (CR) galaxies are systems hosting two large-scale stellar components rotating in opposite directions—a main, preexisting galaxy body with an older stellar population and a younger CR stellar disk likely formed from externally ...

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable

Probing the History of the Galaxy Assembly of the Counterrotating Disk Galaxy PGC 66551

open access: yesThe Astrophysical Journal
Stellar counterrotation in disk galaxies directly relates to the complex phenomenon of the disk mass assembly believed to be driven by external processes, such as accretion and mergers.

The multiple corrugations in the Galactic disk derived from the LAMOST and Gaia survey data

open access: yesAstronomy & Astrophysics
Context. Large spectroscopic and astrometric surveys have revealed complex wave-like features in the Milky Way disk, suggesting that its kinematic and chemical structures are shaped by time-dependent perturbations.

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

open access: yesPeople and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

Blue Supergiants in the Pinwheel Galaxy M101: Comparison with H II Region Chemical Abundances, Spectroscopic Distance, and an Independent Determination of the Hubble Constant

open access: yesThe Astrophysical Journal
We present a quantitative spectroscopic study of 13 blue supergiant stars in the Pinwheel Galaxy M101, based on data obtained with the Low Resolution Imaging Spectrometer available at the Keck I telescope.
