Molecular dynamics simulations of cascade overlap with Void/Helium bubble

Nuclear Materials and Energy, 2022
When tungsten (W) is used as a plasma-facing material in fusion reactors, it will suffer irradiation from the high-energy neutron and high-flux low-energy helium (He) plasma, affording voids and He bubbles with varying helium-to-vacancy ratios (He/V ...

Very Large Baseline Array observations of Mrk 6 : probing the jet-lobe connection [PDF]

, 2014
We present the results of high-resolution VLBI (very long baseline interferometry) observations at 1.6 and 4.9 GHz of the radio-loud Seyfert galaxy, Mrk 6. These observations are able to detect a compact radio core in this galaxy for the first time.

A diffuse bubble-like radio-halo source MRC 0116+111: imprint of AGN feedback in a low-mass cluster of galaxies [PDF]

, 2009
We present detailed observations of MRC 0116+111, revealing a luminous, mini radio-halo of ~240 kpc diameter located at the centre of a cluster of galaxies at redshift z = 0.131.

Reconstruction of Fermi and eROSITA Bubbles from Magnetized Jet Eruption with Simulations

Universe
The Fermi bubbles and the eROSITA bubbles around the Milky Way Galaxy are speculated to be the aftermaths of past jet eruptions from a supermassive black hole in the galactic center.

Filamentary Alfvénic structures excited at the edges of equatorial plasma bubbles [PDF]

Annales Geophysicae, 2007
Recent observations performed by the French DEMETER satellite at altitudes of about 710 km suggest that the generation of equatorial plasma bubbles correlates with the presence of filamentary structures of field aligned currents carried by Alfvén ...

Steady-State Hadronic Gamma-Ray Emission from 100-Myr-Old Fermi Bubbles

, 2014
The Fermi Bubbles are enigmatic \gamma-ray features of the Galactic bulge. Both putative activity (within $\sim$ few $\times$ Myr) connected to the Galactic center super-massive black hole and, alternatively, nuclear star formation have been claimed as ...

Multipoint observations of equatorial plasma bubbles [PDF]

Journal of Geophysical Research: Space Physics, 2003
This paper compares evening sector measurements by the Jicamarca unattended long‐term studies of the ionosphere and atmosphere (JULIA) radar, the Ancon scintillation monitor, and plasma density sensors on Defense Meteorological Satellite Program (DMSP) satellites. During more than half of the 110 nights of JULIA operations in 1998 and 1999, backscatter

Plasma Production in Isolated Bubbles

IEEE Transactions on Plasma Science, 2014
The production of plasma in isolated (i.e., unattached to a physical electrode) air bubbles in liquid water is investigated. Bubble size along with bubble position relative to the pulsed high voltage electrode is considered.

Onset of cavitation in the quark-gluon plasma [PDF]

, 2014
We study the onset of bubble formation (cavitation) in the quark-gluon plasma as a result of the reduction of the effective pressure from bulk-viscous corrections.
