摘要:

对时域--可变和瞬态物体和现象--的探索正迅速成为一个充满活力的研究前沿,基本上涉及天文学和天体物理学的每一个领域,从太阳系到宇宙学。新一代天气巡天的出现使时域天文学成为可能,这种巡天可以重复覆盖天空的大片区域,并产生大量数据流。他们的科学探索带来了许多挑战,主要是由于需要实时发现,分类和跟踪有趣的事件。在这里,我们描述了卡塔利娜实时瞬态调查(CRTS),发现和发布在光波长的瞬态事件实时,从而使整个社区受益。我们描述了一些迄今为止的科学成果,然后专注于瞬态事件的自动分类和优先级排序的挑战。CRTS是未来大型巡天的科学和技术试验平台和先驱,包括大型综合巡天望远镜(LSST)和平方公里阵列(SKA)。

英文摘要:

Exploration of the time domain - variable and transient objects and phenomena - is rapidly becoming a vibrant research frontier, touching on essentially every field of astronomy and astrophysics, from the Solar system to cosmology. Time domain astronomy is being enabled by the advent of the new generation of synoptic sky surveys that cover large areas on the sky repeatedly, and generating massive data streams. Their scientific exploration poses many challenges, driven mainly by the need for a real-time discovery, classification, and follow-up of the interesting events. Here we describe the Catalina Real-Time Transient Survey (CRTS), that discovers and publishes transient events at optical wavelengths in real time, thus benefiting the entire community. We describe some of the scientific results to date, and then focus on the challenges of the automated classification and prioritization of transient events. CRTS represents a scientific and a technological testbed and precursor for the larger surveys in the future, including the Large Synoptic Survey Telescope (LSST) and the Square Kilometer Array (SKA).
