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…
Measurement of AGN dust extinction based on the near-infrared flux variability of WISE data
Shoichiro Mizukoshi, Takeo Minezaki, Shoichi Tsunetsugu +4
We present the measurement of the line-of-sight extinction of the dusty torus for a large number of obscured active galactic nuclei (AGNs) based on the reddening of the colour of t…
Finding of a population of active galactic nuclei showing a significant luminosity decline in the past yrs
J. Pflugradt, K. Ichikawa, M. Akiyama +4
Recent observations have revealed an interesting active galactic nuclei (AGN) subclass that shows strong activity at large scales ( kpc) but weaker at small scales ( pc…
NuSTAR Non-detection of a Faint Active Galactic Nucleus in an Ultraluminous IR Galaxy with Kpc-scale Fast Wind
Xiaoyang Chen, Kohei Ichikawa, Hirofumi Noda +4
Large-scale outflows are generally considered as a possible evidence that active galactic nuclei (AGNs) can severely affect their host galaxies. Recently an ultraluminous IR galaxy…
Dust Reverberation Mapping of Type 2 AGN NGC 2110 Realized with X-ray and 3-5 m IR monitoring
Hirofumi Noda, Taiki Kawamuro, Mitsuru Kokubo +1
The dust reverberation mapping is one of powerful methods to investigate the structure of the dusty tori in AGNs, and it has been performed on more than a hundred type 1 AGNs. Howe…
Tracing the co-evolution path of super massive black holes and spheroids with AKARI-selected ultra-luminous IR galaxies at intermediate redshifts
Xiao-Yang Chen, Masayuki Akiyama, Kohei Ichikawa +6
We present the stellar population and ionized-gas outflow properties of ultra-luminous IR galaxies (ULIRGs) at 0.1-1.0, which are selected from AKARI FIR all-sky survey. We co…
