The young radio lobe of 3C 84: inferred gas properties in the central 10 parsec

Yutaka Fujita, Nozomu Kawakatu, Isaac Shlosman +1

We analyse the environment of the supermassive black hole (SMBH) in the centre of a massive elliptical galaxy NGC 1275 in the Perseus cluster, hosting the radio source 3C 84. We fo…

Photospheric Emission from Collapsar Jets in 3D Relativistic Hydrodynamics

Hirotaka Ito, Jin Matsumoto, Shigehiro Nagataki +2

We explore the photospheric emission from a relativistic jet breaking out from a massive stellar envelope based on relativistic hydrodynamical simulations and post-process radiatio…

Fossil shell emission in dying radio loud AGNs

M. Kino, H. Ito, N. Kawakatu +4

We investigate shell emission associated with dying radio loud AGNs. First, based on our recent work by Ito et al. (2015), we describe the dynamical and spectral evolutions of shel…

Matter Mixing in Core-collapse Supernova Ejecta: Large Density Perturbations in the Progenitor Star?

J. Mao, M. Ono, S. Nagataki +5

Matter mixing is one important topic in the study of core-collapse supernova (CCSN) explosions. In this paper, we perform two-dimensional hydrodynamic simulations to reproduce the…

Particle acceleration in superluminal strong waves

Yuto Teraki, Hirotaka Ito, Shigehiro Nagataki

We calculate the electron acceleration in random superluminal strong waves (SLSWs) and radiation from them by using numerical methods in the context of the termination shock of the…

The Fate of Dead Radio-loud Active Galactic Nuclei: A New Prediction of Long-lived Shell Emission

Hirotaka Ito, Motoki Kino, Nozomu Kawakatu +1

We examine the fate of a dead radio source in which jet injection from the central engine has stopped at an early stage of its evolution ( yr). To this aim,…
