Superluminous supernovae (SLSNe) are extraordinary events; 100 times brighter than normal supernova. Recent advances in survey astronomy have started to uncover these explosions at a much higher rate than previously envisioned and future surveys by LSST could uncover thousands of such events. This studentship will investigate the continued detection and quantification of this population of events, looking at their physical properties (luminosities, environments) and determining if they form a coherent, homogeneous population. While looking for SLSNe, other interesting objects are possible including gravitationally lensed supernova which are rarer than SLSNe but provide possibly the perfect cosmological probe. This studentship will investigate using data from Dark Energy Survey and LSST simulations to assess the two phenomena.

超光超新星(SLSNe)是一种非同寻常的事件；比正常超新星亮100倍。调查天文学最近的进步已经开始发现这些爆炸的速度比之前预想的要高得多，LSST未来的调查可能会发现数千起这样的事件。这门课程将研究这种事件群体的持续检测和量化，观察它们的物理性质(亮度、环境)，并确定它们是否形成一个连贯的、同质的群体。在寻找SLSNe的同时，其他有趣的物体也是可能的，包括引力透镜超新星，它比SLSNe稀有，但可能提供完美的宇宙学探测器。这项研究将使用暗能量调查和LSST模拟的数据来评估这两种现象。
