More strange sounds from deep space have been detected, also know as Fast Radio Bursts or FRB from a collaboration of ground based telescopes around the world.
This is not the first time an FRB has been detected, first detected by a radio telescope in Australia in 2014. Some say it is evidence of intelligent extraterrestrial life in deep space. Now scientist have come closer than ever to pin pointing the exact location from which theses signals are coming from.
Fast radio bursts (FRBs) are millisecond-duration events thought to originate beyond the Milky Way galaxy. Uncertainty surrounding the burst sources, and their propagation through intervening plasma, has limited their use as cosmological probes.
We report on a mildly dispersed (dispersion measure 266.5 ± 0.1 pc cm−3), exceptionally intense (120 ± 30 Jy), linearly polarized, scintillating burst (FRB 150807) that we directly localize to 9 arcmin2. Based on a low Faraday rotation (12.0 ± 0.7 rad m−2), we infer negligible magnetization in the circum-burst plasma and constrain the net magnetization of the cosmic web along this sightline to <21 nG, parallel to the line-of-sight.
The burst scintillation suggests weak turbulence in the ionized intergalactic medium.
