Abstract:
New observational methods often trigger new discoveries in astronomy. To explore the universe innovatively, we plan to perform the 7-dimensional sky survey (7DS), a wide field, time series, spectral mapping of the southern sky. The survey aims to (i) understand the spectral variability of astronomical sources through time series spectral mapping; (ii) provide a spectral map of the sky that can be used to study spatially resolved stellar population of galaxies, cosmology, etc; and (iii) rapidly identify electromagnetic counterparts of gravitational-wave sources for successful multi-messenger astronomy. In this talk, we will introduce the 7-Dimensional Telescope (7DT) that will perform 7DS and the unsolved problems that 7DS will tackle. 7DT is expected to start its observation by the end of 2022, with 7 DS starting in early 2023.

**Talk to be delivered in English.
