Task Description and Goals

There is a growing interest in the extragalactic community to explore the low-surface brightness Universe and large-scale structure intensity mapping. Such studies require wide-field imaging with stable photometry and low sky noise, ideally observed from space. Surprisingly, in the most studied optical wavelength, full-sky space-based images weren't available until the recent TESS mission launched by NASA. Since the TESS userbase has been focusing on time series analyses, we still do not have a full-sky map in a convenient format for intensity mapping. This summer, a student will work with Dr. Yi-Kuan Chiang at ASIAA to make the first space-based, full-sky intensity map in the optical using TESS data to unlock the low surface brightness sky for observational cosmology.
