pop-cosmos: A Comprehensive Picture of the Galaxy Population from COSMOS Data
The Astrophysical Journal Supplement SeriesWe present pop-cosmos : a comprehensive model characterizing the galaxy population, calibrated to 140,938 ( r < 25 selected) galaxies from the Cosmic Evolution Survey (COSMOS) with photometry in 26 bands from the ultraviolet to the infrared. We construct

Formation rates and evolution histories of magnetars [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We constrain the formation rate of Galactic magnetars directly from observations. Combining spin-down rates, magnetic activity, and association with supernova remnants, we put a 2$\sigma$ limit on their Galactic formation rate at $2.3-20\mbox{kyr}^{-1}$.

Diversity and Ecological Potentials of Marine Viruses Inhabiting Continental Shelf Seas
Advanced Science, EarlyView.To the best of the knowledge, this study provides the largest viral genome dataset from a continental shelf sea. It reveals that over half of vOTUs are novel, highlighting the remarkable viral novelty in the eastern continental shelf seas of China (ECSSC).

Overmerging and M/L ratios in phenomenological galaxy formation models
, 1999 We show that the discrepancy between the Tully-Fisher relation and the luminosity function predicted by most phenomenological galaxy formation models is mainly due to overmerging of galaxy haloes.

The Romulus Cosmological Simulations: A Physical Approach to the Formation, Dynamics and Accretion Models of SMBHs [PDF]
, 2017 We present a novel implementation of supermassive black hole (SMBH) formation, dynamics, and accretion in the massively parallel tree+SPH code, ChaNGa. This approach improves the modeling of SMBHs in fully cosmological simulations, allowing for a more de-

Analysis of the Principle and Simulations for Galaxy Formation
Highlights in Science Engineering and TechnologyAs a matter of fact, the limit to technological advancements seems endless. With the recent launch of the James Webb Space Telescope, cosmological observation has become clearer than ever, allowing us to look deeper into the past.

Ultra-diffuse galaxies outside clusters: clues to their formation and evolution [PDF]
, 2016 We identify six ultra diffuse galaxies (UDGs) outside clusters in three nearby isolated groups (z 250 kpc) of our three groups, we identify a population of potential UDG progenitors (two of them confirmed spectroscopically).

Advanced Science, EarlyView.A microneedle spoilage sensor for packaged food products is presented. The sensor is composed entirely of food‐derived agents, integrated together using a novel material processing approach. This resultant platform nondestructively reports spoilage state in real‐time through a colorimetric output.

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,
