The Visible and Infrared Survey Telescope for Astronomy (VISTA) is the 4-metre wide-field survey telescope at ESO's Paranal Observatory, equipped with the world's largest near-infrared imaging camera (VISTA IR Camera, VIRCAM), with 1.65 degree diameter field of view, and 67 Mpixels giving 0.6 square degrees active pixel area, operating at wavelengths 0.8 - 2.3 microns. We provide a short history of the project, and an overview of the technical details of the full system including the optical design, mirrors, telescope structure, IR camera, active optics, enclosure and software. The system includes several innovative design features such as the f/1 primary mirror, the dichroic cold-baffle camera design and the sophisticated wavefront sensing system delivering closed-loop 5-axis alignment of the secondary mirror. We conclude with a summary of the delivered performance, and a short overview of the six ESO public surveys in progress on VISTA.
The Vista Variables in the Via Lactea (VVV) ESO Public Survey: Current Status and First Results
Via Lactea中的Vista Variables（VVV）是ESO的一项公共调查，正在使用ESO的可见光和红外天文学调查望远镜（VISTA）对银河系隆起和部分内盘进行可变性调查。这次巡天覆盖了ZYJHK_S滤光片中520度^2的天区，总观测时间为1929小时，包括~ 10^9个点源和估计~ 10^6颗变星。在这里，我们描述的VVV调查的现状，除了各种新的结果的基础上VVV数据，包括光变曲线的变星，新发现的球状星团，疏散星团，和协会。本文还介绍了一套基于ZYJHK_S系统的无红化指标。最后，我们提供了一个概述的VVV模板项目，其主要目标是获得定义良好的光变曲线模板在近红外，自动分类的VVV光变曲线。
