Particle loads for cosmological simulations with equal-mass dark matter and baryonic particles
Shihong Liao, Yizhou Liu, Haonan Zheng +5
Traditional cosmological hydrodynamical simulations usually assume equal-numbered but unequal-mass dark matter and baryonic particles, which can lead to spurious collisional heatin…

The Role of Spiral Arms in Galaxies II: Similarities Amid Diversity
Bingqing Sun, Daniela Calzetti, Andrew J. Battisti
The role of spiral arms in galaxies -- whether they enhance star formation efficiency or primarily act as material gatherers -- remains an open question. Observational studies have…

The Role of Spiral Arms in Galaxies
Bingqing Sun, Daniela Calzetti, Andrew J. Battisti
We test the influence of spiral arms on the star formation activity of disk galaxies by constructing and fitting multi-wavelength SEDs for the two nearby spiral galaxies NGC 628 an…
