NuSTAR Discovery of a Compton-thick Dust-obscured Galaxy WISE J0825+3002
Yoshiki Toba, Satoshi Yamada, Yoshihiro Ueda +6
We report the discovery of a Compton-thick (CT) dust-obscured galaxy (DOG) at = 0.89, WISE J082501.48+300257.2 (WISE0825+3002), observed by Nuclear Spectroscopic Telescope Arra…
Torus Constraints in ANEPD-CXO245: A Compton-thick AGN with Double-Peaked Narrow Lines
Takamitsu Miyaji, Martín Herrera-Endoqui, Mirko Krumpe +18
We report on the torus constraints of the Compton-thick AGN with double-peaked optical narrow line region (NLR) emission lines, ANEPD-CXO245, at z=0.449 in the AKARI NEP Deep Field…
A NuSTAR and XMM-Newton Study of the Two Most Actively Star-forming Green Pea Galaxies (SDSS J0749+3337 and SDSS J0822+2241)
Taiki Kawamuro, Yoshihiro Ueda, Kohei Ichikawa +4
We explore X-ray evidence for the presence of active galactic nuclei (AGNs) in the two most actively star-forming Green Pea galaxies (GPs), SDSS J0749+3337 and SDSS J0822+2241, whi…
X-Ray Spectral Model from Clumpy Torus and Its Application to Circinus Galaxy
Atsushi Tanimoto, Yoshihiro Ueda, Hirokazu Odaka +3
We construct an X-ray spectral model from the clumpy torus in an active galactic nucleus (AGN), designated as "XCLUMPY", utilizing the Monte Carlo simulation for Astrophysics and C…
Luminosity Ratio between [O IV] 25.89 um Line and Nuclear Continuum 12 um as Diagnostic for "Buried" AGN
Satoshi Yamada, Yoshihiro Ueda, Atsushi Tanimoto +3
We propose new diagnostics that utilize the [O IV] 25.89 m and nuclear (subarcsecond scale) 12 m luminosity ratio for identifying whether an AGN is deeply `buried' in their s…
Application of Clumpy Torus Model to Broadband X-ray Spectra of Two Seyfert 1 Galaxies: IC 4329A and NGC 7469
Shoji Ogawa, Yoshihiro Ueda, Satoshi Yamada +2
We apply a new X-ray clumpy torus model called XCLUMPY (Tanimoto et al. 2019), where the clump distribution is assumed to be the same as in the infrared clumpy torus model (CLUMPY)…
