The correlation between the 500 pc scale molecular gas masses and AGN powers for massive elliptical galaxies
Yutaka Fujita, Takuma Izumi, Nozomu Kawakatu +3
Massive molecular clouds have been discovered in massive elliptical galaxies at the center of galaxy clusters. Some of this cold gas is expected to flow in the central supermassive…
Diffuse radio source candidate in CIZA J1358.9-4750
Kohei Kurahara, Takuya Akahori, Ruta Kale +11
We report on results of our upgraded Giant Metrewave Radio Telescope (uGMRT) observations for an early-stage merging galaxy cluster, CIZA J1358.9-4750 (CIZA1359), in Band-3 (300--5…
Evidence for powerful winds and the associated reverse shock as the origin of the Fermi bubbles
Yutaka Fujita
The Fermi bubbles are large gamma-ray-emitting structures. They are symmetric about the Galactic Centre (GC), and their creation is therefore attributed to intensive energy injecti…
The Gamma-Ray Emission from the Supernova Remnant RX J1713.7-3946 Interacting with Two-phase Medium
Yutaka Fujita, Ryo Yamazaki, Yutaka Ohira
We study the origin of gamma rays from the supernova remnant (SNR) RX J1713.7-3946. Using an analytical model, we calculate the distribution of cosmic rays (CRs) around the SNRs. M…
Suzaku Observations of Fe K-shell Lines in the Supernova Remnant W51C and Hard X-ray Sources in the Proximity
Aika Shimaguchi, Kumiko K. Nobukawa, Shigeo Yamauchi +2
In this paper, we investigated the Fe K-shell lines in the supernova remnant W51C and hard X-ray sources in the proximity. We measured the intensities of Fe I K and Fe XXV He…
Massive Molecular Gas as a Fuel Tank for Active Galactic Nuclei Feedback in Central Cluster Galaxies
Yutaka Fujita, Nozomu Kawakatu, Hiroshi Nagai
Massive molecular gas has been discovered in giant elliptical galaxies at the centers of galaxy clusters. To reveal its role in active galactic nucleus (AGN) feedback in those gala…
