Suzaku Observations of Moderately Obscured (Compton-thin) Active Galactic Nuclei Selected by Swift/BAT Hard X-ray Survey
Taiki Kawamuro, Yoshihiro Ueda, Fumie Tazaki +2
We report the results obtained by a systematic, broadband (0.5--150 keV) X-ray spectral analysis of moderately obscured (Compton-thin; ) active galacti…
Study of Swift/BAT Selected Low-luminosity Active Galactic Nuclei Observed with Suzaku
Taiki Kawamuro, Yoshihiro Ueda, Fumie Tazaki +2
We systematically analyze the broadband (0.5--200 keV) X-ray spectra of hard X-ray ( keV) selected local low-luminosity active galactic nuclei (LLAGNs) observed with {\it Suza…
PRECL: A new method for interferometry imaging from closure phase
Shiro Ikeda, Fumie Tazaki, Kazunori Akiyama +2
For short-wavelength VLBI observations, it is difficult to measure the phase of the visibility function accurately. The closure phases are reliable measurements under this situatio…
A Radio Detection Survey of Narrow-Line Seyfert 1 Galaxies using Very-Long-Baseline Interferometry at 22 GHz
Akihiro Doi, Tomoaki Oyama, Yusuke Kono +4
We conducted a high-sensitivity radio detection survey for forty narrow-line Seyfert 1 (NLS1) galaxies using very-long-baseline interferometry (VLBI) at 22 GHz through phase-refere…
