Transmission Line Analogy for Relativistic Poynting-Flux Jets
R. V. E. Lovelace, P. P. Kronberg
Radio emission, polarization, and Faraday rotation maps of the radio jet of the galaxy 3C 303 have shown that one knot of this jet carries a {\it galactic}-scale electric current a…
The helical jet of the Vela Pulsar
Martin Durant, Oleg Kargaltsev, George G. Pavlov +2
We have studied the fascinating dynamics of the nearby Vela pulsar's nebula in a campaign comprising eleven 40ks observations with Chandra X-ray Observatory (CXO). The deepest yet…
General-Relativistic Simulations of Three-Dimensional Core-Collapse Supernovae
C. D. Ott, E. Abdikamalov, P. Moesta +6
We study the three-dimensional (3D) hydrodynamics of the post-core-bounce phase of the collapse of a 27-solar-mass star and pay special attention to the development of the standing…
Ortho-to-Para Ratio Studies of Shocked H2 Gas in the Two Supernova Remnants IC 443 and HB 21
Jong-Ho Shinn, Ho-Gyu Lee, Dae-Sik Moon
We present near-infrared (2.5-5.0 μm) spectral studies of shocked H2 gas in the two supernova remnants IC 443 and HB 21, which are well known for their interactions with nearby mol…
Charged current neutrino interactions in core-collapse supernovae in a virial expansion
C. J. Horowitz, G. Shen, Evan O'Connor +1
Core-collapse supernovae may depend sensitively on charged current neutrino interactions in warm, low density neutron rich matter. A proton in neutron rich matter is more tightly b…
GRB 120422A: A Low-luminosity Gamma-ray Burst Driven by Central Engine
Bin-Bin Zhang, Yi-Zhong Fan, Rong-Feng Shen +6
GRB 120422A is a low-luminosity Gamma-ray burst (GRB) associated with a bright supernova, which distinguishes itself by its relatively short T90 ~ 5 s and an energetic X-ray tail.…
