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…
Blackbody Quasar and Radio Source (BBQSORS): A Candidate of Transitional Little Red Dots with a Blackbody Spectrum
Yuxing Zhong, Xiaoyang Chen, Kohei Ichikawa +12
We report Subaru/PFS spectroscopic follow-up of a radio-loud quasar at from the UNVEIL radio AGN catalog and with X-ray detections. The PFS spectrum displays a broad MgII…
Diverse Origins of Broad H Lines in Heavily Obscured AGNs Revealed by Multi-epoch Spectroscopy
Shoichiro Mizukoshi, Takeo Minezaki, Subaru Ubukata +8
According to the classical AGN model, broad emission lines originate from the broad-line region (BLR) and are observable only when the attenuation by the dusty torus is small. Howe…
The dynamic central environment of NGC 3516 revealed by XRISM
Anna Juráňová, Erin Kara, Ehud Behar +15
We present a detailed, time-resolved analysis of the Fe K band of the Seyfert 1.5 galaxy NGC 3516 observed with XRISM. The 249 ks observation spanning 310 ks in elapsed time…
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…
Discovery of an X-ray Luminous Radio-Loud Quasar at : A Possible Transitional Super-Eddington Phase
Sakiko Obuchi, Kohei Ichikawa, Satoshi Yamada +11
We report the multiwavelength properties of eFEDS J084222.9+001000 (hereafter ID830), a quasar at , identified as the most X-ray luminous radio-loud quasar in the eROSITA…
Updated Picture of the Active Galactic Nuclei with Dusty/Dust-free Gas Structures and Effects of the Radiation Pressure
Shoichiro Mizukoshi, Takeo Minezaki, Hiroaki Sameshima +5
This study investigates the properties of two gas structures of X-ray selected active galactic nuclei (AGNs), that is, dusty and dust-free gas components, by separating them with t…
ALMA Lensing Cluster Survey: Full SED Analysis of z~0.5-6 Lensed Galaxies Detected with Millimeter Observations
Ryosuke Uematsu, Yoshihiro Ueda, Kotaro Kohno +17
Sub/millimeter galaxies are a key population for the study of galaxy evolution because the majority of star formation at high redshifts occurred in galaxies deeply embedded in dust…
Co-evolution and Nuclear Structure in the Dwarf Galaxy POX 52 Studied by Multi-wavelength Data From Radio to X-ray
Taiki Kawamuro, Claudio Ricci, Satoshi Yamada +4
The nearby dwarf galaxy POX 52 at hosts an active galactic nucleus (AGN) with a black-hole (BH) mass of and an Eddington ratio of $\s…
AGN number fraction in galaxy groups and clusters at z < 1.4 from the Subaru Hyper Suprime-Cam survey
Aoi Hashiguchi, Yoshiki Toba, Naomi Ota +20
One of the key questions on active galactic nuclei (AGN) in galaxy clusters is how AGN could affect the formation and evolution of member galaxies and galaxy clusters in the histor…
