Diffusion activation energy and desorption activation energy for astrochemically relevant species on water ice show no clear relation
Kenji Furuya, Tetsuya Hama, Yasuhiro Oba +3
The activation energy for desorption (Edes) and that for surface diffusion (Esd) of adsorbed molecules on dust grains are two of the most important parameters for the chemistry in…
Penetration of Non-energetic Hydrogen Atoms into Amorphous Solid Water and their Reaction with Embedded Benzene and Naphthalene
Masashi Tsuge, Akira Kouchi, Naoki Watanabe
Chemical processes on the surface of icy grains play an important role in the chemical evolution in molecular clouds. In particular, reactions involving non-energetic hydrogen atom…
Material properties of a low contraction and resistivity silicon-aluminum composite for cryogenic detectors
Tatsuya Takekoshi, Kianhong Lee, Kah Wuy Chin +9
We report on the cryogenic properties of a low-contraction silicon-aluminum composite, namely Japan Fine Ceramics SA001, to use as a packaging structure for cryogenic silicon devic…
Efficient formation pathway of methyl formate: the role of OH radicals on ice dust
A. Ishibashi, H. Hidaka, Y. Oba +2
Three structural isomers of the C2H4O2 molecule, namely, methyl formate (MF; HCOOCH3), acetic acid (AA; CH3COOH), and glycol aldehyde (GA; HOCH2CHO), have attracted considerable at…
DESHIMA 2.0: development of an integrated superconducting spectrometer for science-grade astronomical observations
Akio Taniguchi, Tom J. L. C. Bakx, Jochem J. A. Baselmans +32
Integrated superconducting spectrometer (ISS) technology will enable ultra-wideband, integral-field spectroscopy for (sub)millimeter-wave astronomy, in particular, for uncovering t…
Measurements of Ortho-to-para Nuclear Spin Conversion of H2 on Low-temperature Carbonaceous Grain Analogues: Diamond-like Carbon and Graphite
Masashi Tsuge, Akira Kouchi, Naoki Watanabe
Hydrogen molecules have two nuclear spin isomers: ortho-H2 and para-H2. The ortho-to-para ratio (OPR) is known to affect chemical evolution as well as gas dynamics in space. Theref…
