Atomic Carbon in the Central Molecular Zone of the Milky Way : Possible Cosmic-ray Induced Chemistry or Time-Dependent Chemistry Associated with SNR Sagittarius A East
Kunihiko Tanaka, Makoto Nagai, Kazuhisa Kamegai
Being one of the most abundant atomic/molecular species observed in dense molecular gas, atomic carbon () is a potential good tracer of molecular gas mass in many che…
HCN =4-3, HNC =1-0, =1-0, and =10-9 Maps of Galactic Center Region II.: Physical Properties of Dense Gas Clumps and Probability of Star Formation
Kunihiko Tanaka, Makoto Nagai, Kazuhisa Kamegai +2
We report a statistical analysis exploring the origin of the overall low star formation efficiency (SFE) of the Galactic central molecular zone (CMZ) and the SFE diversity among th…
Observations and Analysis of Absorption Lines including J = K Rotational Levels of CH3CN: The Envelope of Sagittarius B2(M)
Mitsunori Araki, Shuro Takano, Nobuhiko Kuze +5
Molecules in diffuse and translucent clouds experience cooling as a result of radiation and less excitation from collisions. However, a rotation around a molecular axis of acetonit…
HCN =4-3, HNC =1-0, =1-0, and =10-9 Maps of Galactic Center Region I: Spatially-Resolved Measurements of Physical Conditions and Chemical Composition
Kunihiko Tanaka, Makoto Nagai, Kazuhisa Kamegai +2
This {\it supplement} paper presents the maps of HCN =4-3, HNC =1-0, =1-0, and HCN =10-9 for the Galactic central molecular zone (CMZ), which ha…
FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) I: Project Overview and Initial Results
Tomofumi Umemoto, Tetsuhiro Minamidani, Nario Kuno +41
The FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) project is one of the legacy projects using the new multi-beam FOREST receiver installed…
A Molecular Line Observation toward Massive Clumps Associated with Infrared Dark Clouds
Takeshi Sakai, Nami Sakai, Kazuhisa Kamegai +4
We have surveyed the N2H+ J=1-0, HC3N J=5-4, CCS J_N=4_3-3_2, NH3 (J, K) = (1, 1), (2, 2), (3, 3), and CH3OH J=7-6 lines toward the 55 massive clumps associated with infrared dark…
