Vigorous turbulence driven by quasar-mode feedback in a cluster core
Satoshi Yamada, Shutaro Ueda, Hirofumi Noda +9
Quasars are among the most luminous objects. They are powered by accretion onto supermassive black holes. They are thought to impact cosmological evolution primarily through energe…
Insights into Jet-Induced Cloud Disruption in NGC 1316: ALMA Reveals a Spatially Extended Molecular Gas
Kana Morokuma-Matsui, Alexander Y. Wagner, Filippo M. Maccagni +14
We present ALMA CO() observations of a nearby radio galaxy NGC1316 at a 100-pc resolution to investigate the impact of AGN jets on the molecular gas. The molecular gas exhib…
Accurate Determination of Chemical Abundances near a Supermassive Black Hole
The XRISM collaboration
The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a un…
A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87
XRISM Collaboration, M. Audard, H. Awaki +138
The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…
Chlorine and Potassium Enrichment in the Cassiopeia A Supernova Remnant
XRISM collaboration
The elements in the universe are synthesized primarily in stars and supernovae, where nuclear fusion favors the production of even-Z elements. In contrast, odd-Z elements are less…
Structured ionized winds shooting out from a quasar at relativistic speeds
XRISM collaboration
Evidence indicates that supermassive black holes exist at the centers of most galaxies. Their mass correlates with the galactic bulge mass, suggesting a co-evolution with their hos…
The bulk motion of gas in the core of the Centaurus galaxy cluster
XRISM collaboration
Galaxy clusters, the largest gravitationally bound structures in the Universe, contain vast amounts of dark matter, galaxies, and hot ionised gas known as the intracluster medium (…
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).…
The XRISM/Resolve view of the Fe K region of Cyg X-3
XRISM Collaboration
The X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution X-ray spectroscopy uniquely probes th…
Comprehensive study of magnetic field evolution in relativistic jets based on 2D simulations
Amin Esmaeili, Yutaka Fujita
We use two-dimensional particle-in-cell simulations to investigate the generation and evolution of the magnetic field associated with the propagation of a jet for various initial c…
Broadband non-thermal emission of odd radio circles induced by explosive galactic outflow remnants and their evolution
Yutaka Fujita, Norita Kawanaka, Susumu Inoue
Odd radio circles (ORCs) are mysterious rings of faint, diffuse emission recently discovered in radio surveys, some of which may be associated with galaxies in relatively dense env…
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…
Supermassive black hole feeding and feedback observed on sub-parsec scales
Takuma Izumi, Keiichi Wada, Masatoshi Imanishi +8
Active galaxies contain a supermassive black hole at their center, which grows by accreting matter from the surrounding galaxy. The accretion process in the central ~10 parsecs has…
