Abstract
As the main observational facility of Center for the Gravitational-Wave Universe at Seoul National University, the 7-Dimensional Telescope (7DT) is a multi-telescope system designed to identify electro-magnetic (EM) counterparts of gravitational-wave (GW) sources. Consisting of 20 50-cm telescopes along with 40 medium-band filters of 25-nm full width at half maximum, 7DT can obtain spectral mapping images for a large field of view (~1.25 square degrees). This multi-object spectral imaging capability along with flexible operation, real-time data reduction and analysis enable 7DT to follow up GW events quickly and to discover EM counterparts with unmatched efficiency. 12 of the 20 planned telescopes are deployed at El Sauce Observatory located at Rio Hurtado Valley in Chile. Since we obtained the first light of 7DT in October 2023, we started its commissioning procedures including examination of bias levels, master flat production, and spectrophotometric standardization. In this talk, we present details of instruments and their set-up, commissioning procedures and data characteristics of 7DT along with our three-layered surveys which are assumed to initiate in early 2024.

Dr. Ji Hoon Kim is Associate Research Professor working at Astronomical Research Center, Seoul National University. An extragalactic observer by trade, Dr. Kim has worked on stellar populations, dynamics, and star-forming interstellar medium of late-type galaxies as well as host galaxies of active galactic nuclei. Since having worked as Subaru Support Astronomer at Maunakea, Dr. Kim has been working on scientific instruments and operation systems for small-aperture telescopes both for research and public facilities. At Seoul National University, Dr. Kim is assuming a role of project manager for the 7-Dimensional Telescope which is a follow-up observation facility for gravitational-wave electromagnetic counterparts.
