IllustrisTNG in the HSC-SSP: image data release and the major role of mini mergers as drivers of asymmetry and star formation

Kavli Affiliate: John D. Silverman | First 5 Authors: , , , , | Summary: At fixed galaxy stellar mass, there is a clear observational connection between structural asymmetry and offset from the star forming main sequence, $Delta$SFMS. Herein, we use the TNG50 simulation to investigate the relative roles of major mergers (stellar mass ratios […]

Enhancement of gravitational waves at Q-ball decay including non-linear density perturbations

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Kai Murai, , , | Summary: The existence of a stochastic gravitational wave background is indicated by the recent pulsar timing array (PTA) experiments. We study the enhanced production of second-order gravitational waves from the scalar perturbations when the universe experiences a transition from the […]

SwinV2DNet: Pyramid and Self-Supervision Compounded Feature Learning for Remote Sensing Images Change Detection

Kavli Affiliate: Jia Liu | First 5 Authors: Dalong Zheng, Zebin Wu, Jia Liu, Zhihui Wei, | Summary: Among the current mainstream change detection networks, transformer is deficient in the ability to capture accurate low-level details, while convolutional neural network (CNN) is wanting in the capacity to understand global information and establish remote spatial relationships. […]
