TESSELLATE Sky Survey
收藏资源简介:
TESSELLATE Sky Survey是由新西兰坎特伯雷大学物理与化学学院等研究机构创建的数据集。该数据集是一个完整开放的目录,包含了由TESS空间望远镜观测到的所有变天空数据。数据集涵盖了广泛的变现象,包括快速蓝光瞬变事件和伽马射线暴余辉等。创建该数据集是为了系统地识别和记录TESS档案中每个完整帧图像中的瞬变、变量和非恒星信号。数据集的创建过程基于TESSreduce差异成像流程,使用机器学习技术和公民科学家的工作来分类事件。该数据集的应用领域是天体物理中的时域天文学研究,旨在解决变星、系外行星候选者、小行星等问题。
TESSELLATE Sky Survey is a dataset developed by the School of Physical and Chemical Sciences, University of Canterbury, New Zealand, and other research institutions. It is a comprehensive open-access catalog containing all variable celestial data observed by the Transiting Exoplanet Survey Satellite (TESS). The dataset covers a wide range of variability phenomena, including Fast Blue Optical Transients (FBOTs), gamma-ray burst afterglows, and others. This dataset was created to systematically identify and document transient, variable, and non-stellar signals within every full-frame image in the TESS archive. The construction of the dataset leverages the TESSreduce differential imaging pipeline, utilizing machine learning technologies and contributions from citizen scientists to classify detected events. The dataset is applied in time-domain astronomy research within astrophysics, with the goal of addressing research questions related to variable stars, exoplanet candidates, asteroids, and other celestial objects.
