A Photo-Hadronic Model of the Large Scale Jets of 3C 273 and PKS 1136-135
Masaaki Kusunose, Fumio Takahara
X-ray bright knots of kpc-scale jets of several radio loud quasars have been an actively discussed issue. Among various models to explain observations, synchrotron radiation from t…
A Photo-Hadronic Model of the Large Scale Jet of PKS 0637-752
Masaaki Kusunose, Fumio Takahara
Strong X-ray emission from large scale jets of radio loud quasars still remains an open problem. Models based on inverse Compton scattering off CMB photons by relativistically beam…
Synchrotron Self-Compton Emission by Relativistic Electrons under Stochastic Acceleration: Application to Mrk 421 and Mrk 501
Jun Kakuwa, Kenji Toma, Katsuaki Asano +2
We examine the applicability of the stochastic electron acceleration to two high synchrotron peaked blazars, Mrk 421 and Mrk 501, assuming synchrotron self-Compton emission of gamm…
Time-Dependent Models for Blazar Emissions with the Second-Order Fermi Acceleration
Katsuaki Asano, Fumio Takahara, Masaaki Kusunose +2
The second-order Fermi acceleration (Fermi-II) driven by turbulence may be responsible for the electron acceleration in blazar jets. We test this model with time-dependent simulati…
A Leptonic Model of Steady High-Energy Gamma-Ray Emission from Sgr A
Masaaki Kusunose, Fumio Takahara
Recent observations of Sgr A by Fermi and HESS have detected steady gamma-ray emission in the GeV and TeV bands. We present a new model to explain the GeV gamma-ray emission by…
Synchrotron Blob Model of Infrared and X-ray Flares from Sagittarius A
Masaaki Kusunose, Fumio Takahara
Sagittarius A in the Galactic center harbors a supermassive black hole and exhibits various active phenomena. Besides quiescent emission in radio and submillimeter radiation, f…
