Cosmic Outliers: Low-spin Halos Explain the Abundance, Compactness, and Redshift Evolution of the Little Red Dots
Published 2025-01-01“…The little red dots (LRDs) are high-redshift galaxies uncovered by JWST, characterized by small effective radii ( R _eff ∼ 80–300 pc), number densities intermediate between typical galaxies and quasars, and a redshift distribution peaked at z ∼ 5. We present a theoretical model in which the LRDs descend from dark matter halos in the extreme low-spin tail of the angular momentum distribution. …”

The Dynamic Prediction Method for Aircraft Cabin Temperatures Based on Flight Test Data
Published 2024-09-01“…The temperature environment of the whole aircraft is divided into zones by the cluster analysis method; the heat transfer mechanism of the aircraft cabin is analyzed for the target area; and the influence of internal and external factors on the thermal environment is considered to establish the temperature environment prediction model of the target cabin. The coefficients of the equations in the model are parameterized to extract the long-term stable terms and trend change terms; with the help of the measured data of the flight state, the model coefficients are determined by a stepwise regression method; and the temperature value inside the aircraft cabin is the output by inputting parameters such as flight altitude, flight speed, and external temperature. …”
