Kinematics of Ultra-High-Velocity Gas in the Expanding Molecular Shell adjacent to the W44 Supernova Remnant
Masaya Yamada, Tomoharu Oka, Shunya Takekawa +6
We mapped the ultra-high-velocity feature (the "Bullet") detected in the expanding molecular shell associated with the W44 supernova remnant using the Nobeyama Radio Observatory 45…
Physical Contact between the +20 km/s Cloud and the Galactic Circumnuclear Disk
Shunya Takekawa, Tomoharu Oka, Kunihiko Tanaka
This paper reports the discovery of evidence for physical contact between the Galactic circumnuclear disk (CND) and an exterior giant molecular cloud. The central 10 pc of our Gala…
A statistical study of giant molecular clouds traced by CO, CO, CS, and CHOH in the disk of NGC 1068 based on ALMA observations
Tomoka Tosaki, Kotaro Kohno, Nanase Harada +7
We present (98 pc) resolution ALMA observations of CO(=1-0), CO(=1-0), CS(=2-1) and CHOH(=-) molecular lines in the central (…
Alleviating Overfitting for Polysemous Words for Word Representation Estimation Using Lexicons
Yuanzhi Ke, Masafumi Hagiwara
Though there are some works on improving distributed word representations using lexicons, the improper overfitting of the words that have multiple meanings is a remaining issue det…
Pseudogap phenomena near the BKT transition of a two-dimensional ultracold Fermi gas in the crossover region
Morio Matsumoto, Ryo Hanai, Daisuke Inotani +1
We investigate strong-coupling properties of a two-dimensional ultracold Fermi gas in the normal phase. In the three-dimensional case, it has been shown that the so-called pseudoga…
Strong-coupling Properties of a -wave Interacting Fermi Gas on the Viewpoint of Specific Heat at Constant Volume
Daisuke Inotani, Pieter van Wyk, Yoji Ohashi
We theoretically investigate the specific heat at constant volume in the normal state of a -wave interacting Fermi gas. Including fluctuations in the -wave Cooper chann…
