The Canadian CHIME radio telescope (Canada Hydrogen Intensity Mapping Experiment) has found 13 new Fast Radio Bursts, including a repeating one, the second known so far, which repeated 5 times. Also two of them are in the low frequency area. Known FRBs were 50 to 60, only one of them repeating. Their origin is unknown.

What in the name of holiness was found in these radio bursts. Were they recorded ? What was the spectrum? Was there any modulation ?

The fact that it was repeated 5 times is interesting, if true---what might be the cause of this if caused by cosmic events? Hard to imagine

They last only milliseconds and the power they have is huge. Power is energy divided by time. So I think they are difficult to analyze.

A genuine ET "we are here" signal would repeat 24/7 surely? Sounds like clutching at straws in a wind to me.


It might be a slewed beacon that bursts five times in one direction and then 5 times in another and so on.

It is a crying shame that no more information appears to be gathered concerning them--as to content, space between ,relative levels of power, same frequency spectrum etc.

Without this information we will run through all the silliness and hopeful speculation once again.

The Canadian scientists are gathering information on the FRBs and they aim to reach a 1000 members sample before attempting any statistics. So we must wait.

about 1.5 billion light years away

Yikes! It amazes me we can even notice that.

Tullio,

Thanks for catching that.

There is a follow-up article over on:

Signals from space: Five theories on what they are

    * A rapidly spinning neutron star
  1. Two stars merging
  2. Blitzar
  3. Black hole
    * Alien life form




Keep searchin',

The CHIME radio telescope was built for mapping hydrogen, instead it discovered FRBs. There is some similarity with the discovery of pulsars. Maybe a steerable radio telescope like Green Bank, Effelsberg, or Sardinia con be aimed at the repeating FRB which must be in the Northern hemisphere since it was sighted by CHIME.

As you're not the OP, I suggest you refrain from such suggestions.

Ubi major minor cessat. I have no objection of my thread on FRBs shifted. to prof. Lawn.
