XMM-Newton --NuSTAR monitoring campaign of the Seyfert 1 galaxy IC 4329A
A. Tortosa, C. Ricci, E. Shablovinskaia +13
We present the results of a joint {\it XMM-Newton} and {\it NuSTAR} campaign on the active galactic nucleus (AGN) IC 4329A, consisting of 9 20 ks {\it XMM-Newton} observat…
BASS XLII: The relation between the covering factor of dusty gas and the Eddington ratio in nearby active galactic nuclei
C. Ricci, K. Ichikawa, M. Stalevski +25
Accreting supermassive black holes (SMBHs) located at the center of galaxies are typically surrounded by large quantities of gas and dust. The structure and evolution of this circu…
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…
BASS XXXIV: A Catalog of the Nuclear Mm-wave Continuum Emission Properties of AGNs Constrained on Scales 100--200 pc
Taiki Kawamuro, Claudio Ricci, Richard F. Mushotzky +25
We present a catalog of the millimeter-wave (mm-wave) continuum properties of 98 nearby ( 0.05) active galactic nuclei (AGNs) selected from the 70-month Swift/BAT hard X-ray c…
BASS-XL: X-ray variability properties of unobscured Active Galactic Nuclei
Alessia Tortosa, Claudio Ricci, Patricia Arévalo +15
We investigate the X-ray variability properties of Seyfert1 Galaxies belonging to the BAT AGN Spectroscopic Survey (BASS). The sample includes 151 unobscured (N c…
A Tight Correlation Between Millimeter and X-ray Emission in Accreting Massive Black Holes from <100 Milliarcsecond-resolution ALMA Observations
Claudio Ricci, Chin-Shin Chang, Taiki Kawamuro +10
Recent studies have proposed that the nuclear millimeter continuum emission observed in nearby active galactic nuclei (AGN) could be created by the same population of electrons tha…
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…
eROSITA Final Equatorial-Depth Survey (eFEDS): eFEDS X-ray view of WERGS Radio Galaxies selected by the Subaru/HSC and VLA/FIRST survey
Kohei Ichikawa, Takuji Yamashita, Andrea Merloni +19
We construct the eROSITA X-ray catalog of radio galaxies discovered by the WERGS survey that is made by the cross-matching of the wide-area Subaru/HSC optical survey and VLA/FIRST…
UGC 4211: A Confirmed Dual Active Galactic Nucleus in the Local Universe at 230 pc Nuclear Separation
Michael J. Koss, Ezequiel Treister, Darshan Kakkad +23
We present multi-wavelength high-spatial resolution (~0.1'', 70 pc) observations of UGC 4211 at z=0.03474, a late-stage major galaxy merger at the closest nuclear separation yet fo…
