Quatre articles cette semaine dans Nature Astronomy reviennent sur les observations du premier FRB de notre galaxie FRB 200428 qui se trouve être associé à un magnétar (SGR 1935+2154). Trois d'entre eux décrivent le sursaut de rayons X qui a pu être observé en coïncidence avec le sursaut radio rapide, par différents télescopes spatiaux : Agile, HXMT et Konus-Wind, et le dernier sur lequel nous allons attarder, s'intéresse aux sursauts de rayons X du magnétar qui ont eu lieu juste avant l'émission du FRB, offrant une comparaison très instructive.

What Does the Weight Lifting Belt Do?

The belt’s main function is to stabilize your core and lower back during heavy lifts by increasing intra-abdominal pressure. This pressure acts as a brace around your spine, helping you keep proper form and protecting you from strain or injury.
