XRISM/Resolve reveals the complex iron structure of NGC 7213: Evidence for radial stratification between inner disk and broad-line region
E. Kammoun, T. Kawamuro, K. Murakami +48
We present the first high-resolution X-ray spectrum of NGC 7213 obtained with XRISM/Resolve, supported by simultaneous XMM-Newton, NuSTAR, and SOAR optical data. The XRISM spectrum…
Molecular Gas in Major Mergers Hosting Dual and Single AGN at <10 kpc Nuclear Separations
Makoto A. Johnstone, Ezequiel Treister, Franz E. Bauer +24
We present high-resolution (50100 pc) Atacama Large Millimeter Array (ALMA) observations of CO(2-1) or CO(1-0) emission in seven local ( 0.05)…
ALMA discovery of Punctum -- a highly polarized mm source in nuclear starburst galaxy NGC 4945
E. Shablovinskaia, C. Ricci, C-S. Chang +9
We report the discovery of a highly polarized millimeter (mm) continuum source in the central region of NGC 4945, identified through ALMA Band 3 observations. This starburst Seyfer…
Quantum Machine Learning for Identifying Transient Events in X-ray Light Curves
Taiki Kawamuro, Shinya Yamada, Shigehiro Nagataki +3
We investigate whether a novel method of quantum machine learning (QML) can identify anomalous events in X-ray light curves as transient events and apply it to detect such events f…
ALMA polarimetry of radio-quiet AGNs
E. Shablovinskaia, C. Ricci, R. Paladino +10
The compact mm emission ubiquitously found in radio-quiet active galactic nuclei (RQ AGN) exhibits properties consistent with synchrotron radiation from a small region (1 lig…
ALMA observation of evolving magnetized corona in the radio-quiet changing-state AGN NGC 1566
Arghajit Jana, Claudio Ricci, Sophie M. Venselaar +9
The origin of compact millimeter (mm) continuum emission from radio-quiet AGNs (RQAGNs) is still not fully understood. Changing-state AGNs (CSAGNs) display rapid and strong variabi…
XMM-Newton Conclusively Identifies an Active Galactic Nucleus in a Green Pea Galaxy
Peter G. Boorman, Jiří Svoboda, Daniel Stern +23
Green Pea galaxies are a class of compact, low-mass, low-metallicity star-forming galaxies in the relatively local universe. They are believed to be analogues of high-redshift gala…
No Galaxy-Scale [CII] Fast Outflow in the z=6.72 Red Quasar HSC J12050000
Mahoshi Sawamura, Takuma Izumi, Kouichiro Nakanishi +17
HSC 120505.09-000027.9 (J12050000) is one of the highest redshift () dust-reddened quasars (red quasars) known to date. We present an improved analysis of Atacama Large…
