有意向购买GTC观测时间的个人或课题组，请在2024年9月30日下午17:00之前将完整的观测计划书PDF发给我们（方玄fangx@nao.cas.cn、施建荣sjr@nao.cas.cn）。，以保障申请人购买的观测时长和数据质量。按照GTC天文台要求，中国每年可购买的GTC观测时间最多为20小时；因此，中国在2025A购买的总时长最好不要超过10小时。请有意购买GTC观测时间的个人或课题组对各自的观测计划进行合理、细致的设计（单个proposal要求的GTC时间最好不超过3–4小时），尽量选取最具科学意义、最适合用GTC观测的源。待GTC观测正式开展后，大家可以直接联系GTC天文台科学运行主管Antonio L.

十字臂是龙虾眼望远镜点扩散函数（PSF）的主要特征。由于所有由龙虾眼望远镜观测的目标都会受十字臂PSF的调制，因此给目标检测算法研发带来了困难。图2 LEIA（爱因斯坦探测器任务的宽视场x射线望远镜的探路者）对银河系中心天区单次观测获得的X射线图像（左图）和模拟图像（右图），左右图的观测时长同为800秒，视场18.6度x18.6度。1200秒变化时，检测纯度都能保持在90%以上）。关于智能光学成像实验室 智能光学成像实验室由贾鹏博士建立，面向国家基础科学装置和战略需求，开展光电系统数字孪生及智能信号处理研究，研究成果服务我国空间站巡天望远镜、欧洲极大光学望远镜、大光学红外望远镜 ...近年来，在国家自然科学基金、载人航天工程和平方公里阵专项项目支持下，融合天文仪器数字孪生和智能数据处理技术开展天文目标信息自动提取和未知天文目标发现研究，助力我国科学实现从0到1的突破。

在这一思想驱使下，他组建了智能光学成像团队，在光学望远镜和图像处理领域开展了自由探索。点扩散函数（PSF）是光学仪器对点状目标的响应。他们利用深度学习技术，建立了存在大气扰动和望远镜状态误差时，望远镜不同视场PSF的建模方法，并将其用于图像复原和望远镜状态估计。为更好地服务于科学研究和公众科学传播，上述软件已开源，并通过国家天文数据科学中心开放下载。图3：有噪声及PSF影响时的模糊星系图像（Degraded），原始星系图像(Original)，有参考的图像复原结果（GalaxyGAN），几种低参考图像复原结果（DIROL及CycleGAN）。他将天文数据作为数字图像处理、科技文献检索及利用等课程的背景资料和材料，设计了”太原理工大学数据标注平台“等校内教学服务网站，组织学生开展教学科研结合的早期训练，开拓了学生的眼界 ...
