用Palomar瞬变工厂探测光学瞬变天空
Exploring the Optical Transient Sky with the Palomar Transient Factory
摘要：
Palomar Transient Factory（PTF）是一个宽视场实验，旨在研究从几分钟到几年的时间尺度上的光学瞬变和变化的天空。PTF使用CFH 12 k镶嵌相机，视场为7.9度^2，底片比例为1 asec/像素，安装在帕洛玛天文台的48英寸塞缪尔·奥申望远镜上。PTF的操作策略被设计成探测瞬态相空间中存在的间隙，并搜索理论上预测的，但尚未检测到的现象，如回落超新星，macronovae，.Ia超新星和孤儿余辉的伽马射线暴。PTF还将发现已知源类的许多新成员，从各种化身中的灾难性变量到超新星和活动星系核，并将为理解银河系动力学（通过RR Lyrics恒星）和太阳系（小行星和近地天体）提供重要见解。从PTF中可以学到的经验教训对于准备未来的大型天气巡天观测（如大型天气巡天望远镜）至关重要。在本文中，我们提出了PTF的科学动机，并详细描述了这项实验的目标和期望。
英文摘要：
The Palomar Transient Factory (PTF) is a wide-field experiment designed to investigate the optical transient and variable sky on time scales from minutes to years. PTF uses the CFH12k mosaic camera, with a field of view of 7.9 deg^2 and a plate scale of 1 asec/pixel, mounted on the the Palomar Observatory 48-inch Samuel Oschin Telescope. The PTF operation strategy is devised to probe the existing gaps in the transient phase space and to search for theoretically predicted, but not yet detected, phenomena, such as fallback supernovae, macronovae, .Ia supernovae and the orphan afterglows of gamma-ray bursts. PTF will also discover many new members of known source classes, from cataclysmic variables in their various avatars to supernovae and active galactic nuclei, and will provide important insights into understanding galactic dynamics (through RR Lyrae stars) and the Solar system (asteroids and near-Earth objects). The lessons that can be learned from PTF will be essential for the preparation of future large synoptic sky surveys like the Large Synoptic Survey Telescope. In this paper we present the scientific motivation for PTF and describe in detail the goals and expectations for this experiment.
