Systematic Study of the Inner Structure of Molecular Tori in Nearby U/LIRGs Using Velocity Decomposition of CO Rovibrational Absorption Lines
Autor: Shusuke Onishi, Takao Nakagawa, Shunsuke Baba, Kosei Matsumoto, Naoki Isobe, Mai Shirahata, Hiroshi Terada, Tomonori Usuda, Shinki Oyabu
Publikováno v: The Astrophysical Journal, Vol 976, Iss 1, p 106 (2024)
Determining the inner structure of the molecular torus around an active galactic nucleus is essential for understanding its formation mechanism. However, spatially resolving the torus is difficult because of its small size. To probe the clump conditi

Publikováno v: ASTROPHYSICAL JOURNAL
Understanding the inner structure of the clumpy molecular torus surrounding the active galactic nucleus is essential in revealing the forming mechanism. However, spatially resolving the torus is difficult because of its size of a few parsecs. Thus, t

Autor: Yutaka Ezaki, Takuya Ashida, Kazuhiko Tani, Makoto Endo, Kenji Kamikawa, Akihiro Nagai, Takayuki Ishida, Masao Saito, Tomonori Usuda, Noboru Kawaguchi, Junji Takaki, Nariyama Tatsuya
Publikováno v: Ground-based and Airborne Telescopes VIII.
The Thirty Meter Telescope (TMT) is expected to reveal the birth of galaxies, planetary surfaces and even the atmospheric composition of exoplanets. The TMT is an optical infrared reflecting telescope that uses very large hydrostatic bearings in the

The real throughput: Site plus optics plus in-situ cleaning for an optical-IR telescope
Autor: Tomonori Usuda, Takuya Yamashita, Angel Otarola, Shin Oya, Eric R. Hansen, Hirofumi Okita, Saeko S. Hayashi
Publikováno v: Ground-based and Airborne Telescopes VIII.
How much light from the astronomical object actually reaches the focal plane of a telescope? To what extent the sensitivity can be extended to both ends of the visible wavelengths – ultraviolet (UV) and infrared (IR) – as much as possible from th

We analyzed the young (2.8-Myr-old) binary system FS Tau A using near-infrared (H-band) high-contrast polarimetry data from Subaru/HiCIAO and sub-millimeter CO (J=2-1) line emission data from ALMA. Both the near-infrared and sub-millimeter observatio
