Early Near-Infrared Excess and Rapid Disk-Corona Evolution in the Tidal Disruption Event 2024aepd
Yongxin Wu, Yanan Wang, Thomas M. Reynolds +38
The paper reports multi-wavelength observations of tidal disruption event 2024aepd, revealing an early near‑infrared excess and a rapid transition from a thermal X‑ray disk to a ha…
Comparative analysis of missing data imputation methods for CSST survey: Impact on photometric redshift estimation performance
Ling Wang, Zhu Chen, Zhijian Luo +42
Improving the accuracy of photometric redshifts (photo-) is essential for reliable statistical studies of cosmology and galaxy evolution. However, missing photometric bands are…
Design, Testing, and Commissioning of the Sun Yat-sen University (SYSU) 80 cm Infrared Telescope
Zhong-Nan Dong, Bin Ma, Chun Chen +23
The Sun Yat-sen University (SYSU) 80 cm telescope is a new generation near-infrared (NIR) facility in China dedicated to time-domain astronomy, while also serving as a testbed for…
A Highly Magnetic Ultra Massive White Dwarf with a 23-minute Rotation Period
Jincheng Guo, Xiaofeng Wang, Qichun Liu +17
We present a physical characterization of TMTS J00063798+3104160 (J0006), a rapidly rotating,ultra-massive white dwarf (WD) identified in high-cadence light curves from the Tsinghu…
Discovery of a Luminosity-dependent Continuum Lag in NGC 4151 from Photometric and Spectroscopic Continuum Reverberation Mapping
Hai-Cheng Feng, Sha-Sha Li, Mouyuan Sun +17
Accretion onto supermassive black holes (SMBHs) powers active galactic nuclei (AGNs) and drives feedback that shapes galaxy evolution. Constraining AGN accretion disk structure is…
Cosmic Ray Detection and Rejection for CSST
Yan Yu, Bin Ma, Tianmeng Zhang +2
As a space telescope, the China Space Station Survey Telescope (CSST) will face significant challenges from cosmic ray (CR) contamination. These CRs will severely degrade image qua…
