FALCON (FERMI-ALMA Calibrator ObservatioN): Cross-matching ALMA Calibrators with Fermi-LAT Blazars

Kanako Narita, Yoshiyuki Inoue, Bunyo Hatsukade +1

Blazars are active galactic nuclei with relativistic jets closely aligned with our line of sight, producing Doppler-boosted emission from radio to gamma rays. Millimeter emission n…

Disk truncation triggers relativistic jet launching of a highly accreting supermassive black hole

Hirofumi Noda, Kazuhiro Hada, Hiroto Maruyama +10

Relativistic jets are among the most energetic phenomena in the Universe and influence galaxy evolution through energetic feedback, yet the physical connection between accretion fl…

Chemical enrichment of the Perseus cluster core seen by XRISM/Resolve

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +143

The intracluster medium (ICM) is rich in chemical elements, produced by core-collapse (SNcc) and Type Ia supernovae (SNIa) over the last 12 Gyr. Whereas cluster outskirts are…

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 Fast, Hot Wind from a Nuclear Starburst

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137

Galaxies with intense star formation often host multiphase, galaxy-scale winds powered by supernovae and fast stellar winds. These are strong enough to disrupt the star-forming int…

High Spectral Resolution X-ray Observations of the Evolved Supermassive Stellar Binary System Carinae - Iron K Band Profile Revealed with XRISM

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +138

The supermassive binary system, Carinae, is experiencing enormous wind-driven mass loss at a rate unparalleled in the rest of the Galaxy. Their wind-wind collision (WWC) contin…

XRISM Discovery of Multiple Ionized Fe-K Emission and Absorption Components in Centaurus A

Taishu Kayanoki, Yasushi Fukazawa, Junjie Mao +13

We present the first clear detection of ionized Fe-K emission and absorption components in the nearby radio galaxy Centaurus A, revealed by the high-resolution XRISM/Resolve detect…

X-ray line diagnostics of the multi-phase gas in the Centaurus cluster core with XRISM/Resolve

Marie Kondo, Kotaro Fukushima, Kazunori Suda +18

We report the multi-temperature structure of the intracluster medium (ICM) in the Centaurus cluster core observed with XRISM/Resolve. Thanks to its high energy resolution, Resolve…

Chemical enrichment in the Ophiuchus cluster core studied by high-resolution XRISM spectroscopy

Kotaro Fukushima, Yutaka Fujita, Kosuke Sato +2

Galaxy clusters provide an ideal laboratory for investigating the chemical enrichment history of the universe because they host the hot intracluster medium (ICM), which contains va…

XRISM finds the Changing-Look AGN NGC 1365 in an extended low state: A dense, highly ionized outflow obscures the central source

Fatima Zaidouni, Erin Kara, Peter Kosec +21

We present the first XRISM/Resolve observations of the active galactic nucleus, NGC 1365, obtained in 2024 February and July. NGC 1365 is known for rapid transitions between Compto…
