论文摘要
IA型超新星观测的数量将在未来十年内看到显着增长,尤其是由于Vera Rubin天文台在智利进行的时空和时间的遗产调查。随着这一上升,统计不确定性将减少,通量校准将成为暗能表征的主要不确定性。在测量IA颜色时,望远镜传输的不确定性是一个主要系统的。在这里,我们介绍了准直的梁投影仪(CBP),该设备可以测量望远镜及其过滤器的传输。由可调的单色光源和光学元件组成,以提供平行输出光束,该设备能够高精度测量过滤器的传输。在下文中,我们将展示如何精确测量望远镜传输还可以提高暗能量参数的精度。例如,我们将在Stardice实验的背景下介绍CBP的第一个结果。
The number of type Ia supernova observations will see a significant growth within the next decade, especially thanks to the Legacy Survey of Space and Time undertaken by the Vera Rubin Observatory in Chile. With this rise, the statistical uncertainties will decrease and the flux calibration will become the main uncertainty for the characterization of dark energy. The uncertainty over the telescope transmission is a major systematic when measuring SNe Ia colors. Here we introduce the Collimated Beam Projector (CBP), a device that can measure the transmission of a telescope and its filters. Composed of a tunable monochromatic light source and optics to provide a parallel output beam this device is able to measure with high precision the filter transmissions. In the following, we will show how measuring precisely a telescope transmission can also improve the precision of the dark energy parameters. As an example, we will present the first results of the CBP in the context of the StarDice experiment.
