Naka-GS: A Bionics-inspired Dual-Branch Naka Correction and Progressive Point Pruning for Low-Light 3DGS
Runyu Zhu, SiXun Dong, Zhiqiang Zhang +2
Low-light conditions severely hinder 3D restoration and reconstruction by degrading image visibility, introducing color distortions, and contaminating geometric priors for downstre…

The Cosmic Evolution and Spatial Distribution of Multiphase Gas associated with QSOs
Zeyu Chen, Enci Wang, Hu Zou +10
We investigate the multi-phase gas surrounding QSOs traced by 33 absorption lines (e.g., Ly, C\,\textsc{iv}, Fe\,\textsc{ii}, Mg\,\textsc{ii}, etc.) in the stacked spectra of ba…

The circumgalactic medium traced by Mg II absorption with DESI: dependence on galaxy stellar mass, star formation rate and azimuthal angle
Zeyu Chen, Enci Wang, Hu Zou +10
Understanding the circumgalactic medium (CGM) distribution of galaxies is the key to revealing the dynamical exchange of materials between galaxies and their surroundings. In this…
