There are two key parameters of the radio emission used in the project.
Figures 5 and 6 show, respectively, the radial distance and the radio emission power for oscillating neutron stars with four different masses under the same initial conditions and the same applied EOS.
"By watching this system over time and seeing how the pattern of radio emission changed, then tracing the movements of the knots, we saw the exact behaviour expected from this scenario," Chomiuk said.
The new VLA observations revealed previously undetected regions where shocks accelerated subatomic particles, causing radio emission.
The presentation by Jeff on the nature of radio emission from the Sun and radio anatomy of a flare was particularly interesting.
If anything, the X-ray emission from the merged object has continued to grow in intensity, as have radio emissions from it.
"Our measurements show that a supernova's own magnetic field is what gives rise to its radio emission, not the magnetic fields in the galaxy around it," says Fabien Batejat.
"Fast radio bursts are brief, bright pulses of radio emission from distant but so far unknown sources, and FRB 121102 is the only one known to repeat: more than 200 high-energy bursts have been observed coming from this source, which is located in a dwarf galaxy about 3 billion light-years from Earth," a statement Wednesday from UC Berkeley explained.
Four of the young brown dwarfs show radio emission due to jets.
"Since the era of the EGRET instrument on the Compton Gamma Ray Observatory in the 1990s, it has been discussed whether outbursts of radio emission are physically connected to similar events occurring at gamma rays" Anton Zensus, Director at the Max Planck Institute for Radio Astronomy (MPIfR) and Fermi Affiliated Scientist said.
Follow-up observations with the Lulin optical telescope in Taiwan and ultraviolet data from NASA's GALEX satellite confirmed that the giant lobes of radio emission, usually seen coming from elliptical galaxies, were coming from a spiral galaxy with ongoing star formation.
