Discovery of CO Clouds Associated with the X-ray Jets of SS 433: Evidence for Shock-Cloud Interaction Enhancing Nonthermal X-ray Emission
Haruka Sakemi, Hidetoshi Sano, Yasuo Fukui +7
We report the first identification of molecular clumps directly associated with the re-brightening regions of the large-scale X-ray jets of SS 433, based on CO ( = 1--0)…
Multiphase Gas Structure in the Circumnuclear Region of NGC 5506 Observed with ALMA
Kana Takechi, Hiroshi Nagai, Nozomu Kawakatu +7
We present a study of the multiphase gas structure and kinematics of the circumnuclear disk (CND) of NGC 5506, a nearby edge-on Seyfert galaxy, at a spatial resolution of …
Re-examination of the CO absorption line in the M87 nucleus
Norita Kawanaka, Hiroshi Nagai, Yutaka Fujita
We analyzed the archival ALMA data of the nuclear region of M87 and evaluate the molecular gas content from the CO(2--1) absorption line. We found an enigmatic variability in the a…
ALMA observations of the gamma-ray binary system PSR B1259-63/LS 2883 during the 2024 periastron passage
Yutaka Fujita, Akiko Kawachi, Atsuo T. Okazaki +3
We present observations of the gamma-ray binary PSR B1259-63/LS 2883 with the Atacama Large Millimeter/submillimeter Array (ALMA) at Bands 3 (97 GHz), 6 (233 GHz), and 7 (343 GHz).…
Implication of a galaxy-scale negative feedback by one of the most powerful multi-phase outflows in a hyper-luminous infrared galaxy at the intermediate redshift
Xiaoyang Chen, Masayuki Akiyama, Kohei Ichikawa +12
Powerful, galactic outflows driven by Active Galactic Nuclei (AGNs) are commonly considered as a main mechanism to regulate star formation in massive galaxies. Ultra- and hyper-lum…
The relationships between AGN power and molecular gas mass within 500 pc of the center of elliptical galaxies
Yutaka Fujita, Takuma Izumi, Hiroshi Nagai +2
The physical quantity that directly controls the feedback of active galactic nuclei (AGNs) in elliptical galaxies remains to be determined. The discovery of molecular gas around th…
Giant Molecular Clouds and Star Formation in the Tidal Molecular Arm of NGC 4039
D. Espada, S. Komugi, E. Muller +23
The properties of tidally induced arms provide a means to study molecular cloud formation and the subsequent star formation under environmental conditions which in principle are di…
