项目摘要

The modern era of wide field optical surveys is revealing new andexotic transient phenomena in unprecedented numbers. The infrared skyis relatively unexplored by comparison. However that is set to changedue to advances in infrared detector technology and new surveyfacilities, such as Gattini IR at Palomar Observatory. The goal ofthis project is to lead the Liverpool Telescope exploitation of theinfrared transient sky. The student will develop and then commision anew InGaAs camera on the telescope, with the aim of having it readyfor full robotic operations in early 2022. This camera will then beused in programmes of transient classification and follow-up. Theprimary targets of interest will be the counterparts of binary neutronstar mergers discovered by the LIGO-Virgo collaboration ofgravitational wave detectors. The fourth science run with thesedetectors is also due to begin in early 2022. Models of the isotropic`kilonova' signature of these merger events shows a strong colourevolution with a peak in the infrared, and this behaviour wasconfirmed by the follow-up of the GW170817 event. A sensitive infraredinstrument on a robotic telescope is therefore a powerful tool for theidentification and characterisation of candidate counterparts. Thestudent will lead the Liverpool Telescope contribution to thefollow-up effort in the O4 run.

现代广域光学测量揭示了前所未有的数量之多的新的奇特的瞬变现象。相比之下，红外线天空相对来说还没有被探索过。然而，由于红外探测器技术的进步和新的测量设施，如帕洛玛天文台的加蒂尼红外，这种情况将发生变化。该项目的目标是领导利物浦望远镜对红外瞬变天空的开发。这名学生将在望远镜上开发并调试一台新的InGaAs相机，目标是在2022年初为全机器人操作做好准备。然后，该摄像机将被用于瞬变分类和跟踪节目。感兴趣的主要目标将是LIGO-Virgo引力波探测器合作发现的双中子星合并的对应物。使用这些探测器的第四次科学运行也将于2022年初开始。这些合并事件的各向同性‘kironova’特征模型显示出强烈的颜色革命和红外峰值，这一行为在GW170817事件的后续行动中得到了证实。因此，机器人望远镜上灵敏的红外仪器是识别和表征候选对应物的有力工具。这名学生将领导利物浦望远镜为O4赛跑的后续工作做出贡献。
