Discovery reveals a reversible magnetic field around a fast radio burst for the first time
快速射电暴 可逆磁场 无线电波闪光
2023/5/15
An international team of researchers has revealed new evidence on the nature of mysterious fast radio bursts (FRBs) – objects in space that produce brief, intense flashes of radio waves from distant g...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Microphysical and non-thermal processes in the circumgalactic medium: turbulence, magnetic fields and cosmic rays
