Identification of gravitational lenses obscured by foreground light in the KiDS dataset using U-Nets and ResNets
S. Liu, Rui Li, J. Jia +13
*Context.* Many lensing images are often obscured by foreground light from the central galaxies, making them challenging to detect. *Aims.* To address the limitations of previous l…
Recalibration of SDSS photometric zero-points based on the InfraRed Flux Method temperature scale
Zenghua Zhou, Luca Casagrande, Heran Xiong +4
Accurate photometric zero-points are essential for translating observed magnitudes into physical fluxes, from comparing with models to ensuring consistency across surveys. We deter…
Characterizing the Instrumental Profile of LAMOST
Qian Liu, Zhongrui Bai, Ming Zhou +9
The instrumental profile (IP) of a telescope is of great significance for spectroscopic analyses, especially for wavelength calibration and stellar parameter measurements. The Larg…
Noise Reduction Method for Radio Astronomy Single Station Observation Based on Wavelet Transform and Mathematical Morphology
Ming-wei Qin, Rui Tang, Ying-hui Zhou +8
The 21 cm radiation of neutral hydrogen provides crucial information for studying the early universe and its evolution. To advance this research, countries have made significant in…
