Categories Necessity Specifications Science goals
Results - Requiring space telescope observations, which overcomes the spatial resolution of ground-based telescopes- Requiring multi-band observations, which overcomes telluric absorptions in UV and IR bands- Synergy with large telescopes, e.g., GMT- Acquiring cutting-edge space technology and spreading public outreach of astronomy - Wide field of view photometric exploration using small aperture telescopes- Narrow field of view but deep photometry and spectroscopy observations in UV, visible, and near-infrared bands- Beyond the retirement of HST around 2030s- Large field of view (>30 arcmin) observations with large aperture (> 3 m) telescopes- Wide spectral ranges in UV, visible, and near-infrared bands- Wide field of view photometry with high-resolution spectroscopy - Active galactic nuclei: accretion disk, black hole mass- High-energy phenomena: white dwarfs, intergalactic medium, interstellar medium at halos- Gravitational lens: exoplanets, galaxy clusters, cosmology, galaxy evolution, low surface brightness features, solar system, multi-messenger astronomy
