摘要:

Zwicky Transient Facility(ZTF)是一家公私合营企业,是一项新的时域测量,采用Palomar 48英寸施密特望远镜上的专用相机,具有47度$^2$视场和8秒读出时间。它在时域天文学的发展中处于有利地位,提供了10%的大型综合巡天望远镜(LSST)的规模和风格,以及一个1米级的巡天望远镜。公共调查将每三个晚上以g和r滤镜覆盖可观察的北方天空,并每晚以g和r滤镜覆盖可见的银河平面。这些调查产生的警报实时发送给经纪人。一个提供资金的大学联盟(“伙伴关系”)正在进行几项小型调查。这些巡天观测的组合每晚产生100万个警报,可以在几分钟到几年的时间尺度上探索比r $\sim$ 20.5更亮的瞬变和可变天体物理现象。我们描述了驱动ZTF的主要科学目标,包括超新星和相对论爆炸的物理学,多信使天体物理学,超新星宇宙学,活动星系核和潮汐破裂事件,恒星变异性和太阳系天体。

英文摘要:

The Zwicky Transient Facility (ZTF), a public-private enterprise, is a new time domain survey employing a dedicated camera on the Palomar 48-inch Schmidt telescope with a 47 deg$^2$ field of view and 8 second readout time. It is well positioned in the development of time domain astronomy, offering operations at 10% of the scale and style of the Large Synoptic Survey Telescope (LSST) with a single 1-m class survey telescope. The public surveys will cover the observable northern sky every three nights in g and r filters and the visible Galactic plane every night in g and r. Alerts generated by these surveys are sent in real time to brokers. A consortium of universities which provided funding ("partnership") are undertaking several boutique surveys. The combination of these surveys producing one million alerts per night allows for exploration of transient and variable astrophysical phenomena brighter than r $\sim$ 20.5 on timescales of minutes to years. We describe the primary science objectives driving ZTF including the physics of supernovae and relativistic explosions, multi-messenger astrophysics, supernova cosmology, active galactic nuclei and tidal disruption events, stellar variability, and Solar System objects.
