论文链接:点击这里。 宇宙中天体发出的电磁波携带着天体的活动信息,是人类与天体交流的信使。当光线在两个方向上都反射偶次或未经过反射直接透过微通道管时光线将成为背景光线,焦点对比度降低。 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。传统上,科学家会根据光子在探测器平面上的位置生成2D图像,并使用经典算法来检测目标。1200秒变化时,检测纯度都能保持在90%以上)。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。

既然这个工作人人都可参与,为何不让大家像游戏一样都玩玩呢,天文如果玩起来一定会很开心的,如此,PSP平台应运而生。可以这么说,PSP系统其实就是一个网上看图平台。PSP系统会在每个整点发放一批图片,并在整点前1分钟弹窗并响音乐提醒(可选)。一旦系统开始发放图片,我们希望您尽快查看,因为越早查看的是越新的图片,本系统会设置一张图片被多个不同的用户各查看一遍,我想您肯定希望自己查看的是最新的未被别人查看过的图啦:)~为避免一张图片被长时间占用 ...为方便交流,大家可以加入XOSS星明天文台巡天QQ群,群号码:73444198,申请时请注明:“真实姓名+省市”,您还可以在群内结识更多资深天文同好,了解参与星明天文台主持的其他巡天项目 ...了解星明天文台观测地的实时天气情况,可以点击这里。了解星明天文台其他情况可以点击这里 马上开始 在线测试 吧 ...
