Posting for public information on the current status of the Roman Coronagraph Observation Calibration Plan; latest updates as of July 29, 2022
NASA's next flagship mission, the Nancy Grace Roman Space Telescope, is a 2.4-meter observatory set to launch no later than May 2027. Roman features two instruments: the Wide Field Imager and the Coronagraph Instrument. Roman's Coronagraph is a Technology Demonstration that will push the current capabilities of direct imaging to smaller contrast ratios ($\sim$10$^{-9}$) and inner-working angles (3~$λ$/D). In order to achieve this high precision, Roman Coronagraph data must be calibrated to remove as many potential sources of error as possible. Here we present a detailed overview of the Nancy Grace Roman Space Telescope Coronagraph Instrument Observation Calibration Plan including identifying potential sources of error and how they will be mitigated via on-sky calibrations.

反射星光测量将为直接成像的系外行星的表征开辟一条新的道路。然而,我们仍然缺乏对适用于这种技术的已知靶点的人群研究。在这里,我们调查的约4300个系外行星的日期确认是访问罗马太空望远镜的日冕(CGI)在反射星光在参考波长$λ$ =575,730和825 nm。我们进行了人口研究,也解决了相位曲线测量的前景。我们使用NASA系外行星档案作为行星和恒星属性的参考,并通过应用统计参数探索其不确定性对系外行星可探测性的影响。我们根据仪器的内外工作角及其最小行星-恒星距离(IWA,OWA,$C_{min}$)来定义行星。对于这些技术规格,我们采用了三种合理的配置,分别标记为悲观、中间和乐观。我们对每颗系外行星的关键输出是它被罗马人接近的概率($P_{access}$),可观测相位角的范围,平衡温度的演变,每个轨道可接近的天数及其过境概率。在乐观的情况下,我们发现了26个罗马人可以接近的系外行星,其$P_{access}$ >25%,其宿主恒星的亮度超过$V$ =7等。这个种群偏向于比木星质量更大的行星,但也包括超级地球τ Cet e和f,它们的轨道靠近恒星的宜居带。共有13颗行星是多行星系统的一部分,其中3颗有已知的凌日伴星,为同时表征提供了机会。中间和悲观的情况分别产生10个和3个罗马人可访问的系外行星。我们发现,倾斜估计(如天体测量)是改善可探测性前景的关键。

A Joint Roman Space Telescope and Rubin Observatory Synthetic Wide-Field Imaging Survey
我们提出并验证了20度$^2$的重叠合成成像调查,代表了南希格雷斯罗马空间望远镜高纬度成像调查(HLIS)的全深度和五年的观察维拉C。Rubin Observatory Legacy Survey of Space and Time(鲁宾天文台时空遗产巡天)这两个综合调查进行了总结,参考现有的300度$^2$的LSST模拟成像的一部分,暗能量科学合作(DESC)数据挑战2(DC 2)。这两次合成巡天观测到的是同一个模拟的DESC DC 2宇宙。对于合成罗马调查,我们首次模拟了全彩色图像以及使用飞行探测器从实验室测量中获得的传感器芯片组件的详细物理特性。模拟成像和所得到的物体光度特性的像素级测量跨越$\sim$ 0.3至2.0 $μ$ m的波长范围。我们还描述了罗马模拟管道的更新,相对于原始DC 2模拟的天体物理对象模拟方式的变化,以及由此产生的模拟罗马数据产品。我们使用这些模拟来探索LSST图像中未识别的混合物的相对比例,发现在LSST图像中识别的$i$波段亮度大于25的对象中有20-30%可以被识别为罗马图像中的多个对象。这些模拟为2020年代后半期开发和验证地基和天基成像数据集的像素级联合分析技术-特别是Roman-LSST联合分析-提供了一个独特的试验场。
