SGFormer: Structure-Guided Transformer for Robust Local Feature Matching
Runyu Zhu
Local feature matching is a fundamental component of photogrammetry, enabling accurate image correspondence critical for tasks such as 3D reconstruction, stereo mapping, and visual…
Environmental Imprints on the Assembly of the Cool Gas around Bright Cluster Galaxies
Runyu Zhu, Hu Zou, Taotao Fang +14
The paper statistically maps cool gas around massive brightest cluster galaxies at z≈0.55 using Mg II absorption from stacked DESI quasar spectra, finding suppressed circumgalactic…
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 b…
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…
