What are Fast Radio Bursts? | The Royal Society

Ғылым және технология

Fast Radio Bursts (FRBs) are short (few millisecond) bursts of radio waves observed from cosmological distances. Their origin is presently unknown, yet their rate is many hundreds per sky per day, indicating a not-uncommon phenomenon in the Universe. In this talk, Professor Kaspi reviewed the FRB field and presented new results on FRBs from a new digital transit radio telescope, the Canadian Hydrogen Intensity Mapping Experiment (CHIME).

    Wow, what are Fast Radio Bursts? For a human, they're like a rabbit hoping to understand a snare trap. Victoria Kaspi from McGill university, ranked #27 globally, her husband is a cardiologist at McGill and at the Sir Mortimer B. He never misses a single episode of Steve Guttenberg's Audiophiliac on You Tube. St Andrews University in Scotland is ranked 292nd globally but recognize no better university. Michigan University is global No.17 and St Andrews has one of their people. So can we really value Vicky's research ... uh ... no. No there are unexplained things that humans cannot really take in, for example that outer space never ends.

    Is there any association of FRBs with GRBs and is there anything optically visible with the FRB repeaters?.

    Neutron Stars are my favorite class of objects in the universe. I just imagine a 1000 mile sphere turned into a crystal that has the most extreme environment in the universe. Just dropping an object waist high and it would approach the speed of light before hitting the ground!!!! Just wow. Spinning so fast you approach the speed of light if you were on the surface WHAT IN THE WORLD!! Having starquakes that well..you get the idea. They're so amazing. Thank you for the lecture. Can't wait to find out if neutron stars are responsible for GRBs.

    I wonder what the odds are of spotting an FRB in an Einstein Ring. Perhaps the great distance would disperse the burst to a huge bandwidth and a peak amplitude too near the noise floor.

    One reason, the phenomena although "common" is rare, since only a few thousand a day among the many stars in range, so "feels" logical the generating object (or object combinations) is not common. The smaller the galaxy, the smaller the variety of object combinations available to do something strange.

    *dosnt know origin of frb. Oh but its far far away* okie dokie. How do you know the frequency dispersion isnt intentionally made. Your hypothesis has more loopholes than me, If these signals are alien made then the frequency dispersion could be a desgined signal and could come from even closer. rather than it being a natural phenomenon it could be engineered which could make this signal alot closer.
