Bar Formation in Milky Way type Galaxies
Open Astronomy, 2016 Many barred galaxies, possibly including the Milky Way, have cusps in their centers. There is a widespread belief, however, that the usual bar instability, which occurs in bulgeless galaxy models, is impossible for cuspy models because of the presence of

Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups
The Astrophysical Journal, 2023 We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the dominant process of environmental quenching in 0.2 < z < 0.8 groups.

TiNy TITANS: THE ROLE OF DWARF–DWARF INTERACTIONS IN LOW-MASS GALAXY EVOLUTION [PDF]
, 2014 We introduce TiNy Titans (TNT), the first systematic study of star formation and the subsequent processing of the interstellar medium in interacting dwarf galaxies. Here we present the first results from a multiwavelength observational program based on a

Revisiting the Fundamental Metallicity Relation with Observation and Simulation
The Astrophysical Journal LettersThe gas-phase metallicity of galaxies is regulated by multiple astrophysical processes, which makes it a crucial diagnostic of galaxy formation and evolution.

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Radial Gradients and Intrinsic Scatter in MaNGA Galaxies
The Astrophysical Journal Supplement SeriesWe derive stellar population parameters and radial gradients within 0.65 R _e for spatially resolved spectra of 2968 early-type galaxies from MaNGA, spanning stellar velocity dispersions ( σ ) of 50–340 km s ^−1 .

Advanced Science, EarlyView.This study reveals that dietary stachyose enriches Butyricimonas virosa, effectively attenuating metabolic dysfunction‐associated steatotic liver disease (MASLD). Mechanistically, B. virosa enhances gut thiamine monophosphate synthesis, which elevates hepatic thiamine pyrophosphate levels.

Warped Disk Galaxies. II. From the Cosmic Web to the Galactic Warp
The Astrophysical JournalGalactic warps are common in disk galaxies. While often attributed to galaxy–galaxy tides, a nonspherical dark matter halo has also been proposed as a driver of disk warping.

Substituent‐Based Modulation of Self‐Assembly and Immunogenicity of Amphipathic Peptides
Advanced Science, EarlyView.This study systematically investigates how positional and subtle changes, such as substituents on the phenyl ring attached to short amphipathic peptides, influence their self‐assembly, fibril morphology, and immunogenic responses. ABSTRACT Self‐assembled peptide‐based biomaterials provide versatile platforms for biomedical uses, featuring customizable ...
