Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle fast radio bursts by discovery, properties, localisation, proposed origins and survey data, with attributed and current findings.

A transient radio pulse lasting milliseconds, of extragalactic origin, first reported in 2007; some sources repeat, and at least one burst has been linked to a magnetar in our galaxy, while the origin of most remains under study.

What it is for: Astrophysics and cosmology.

It can be explain what FRBs are and how they are detected; describe dispersion measure and its use; summarise proposed origins with attribution; find catalogues such as CHIME/FRB.

Distinguishing features

Millisecond duration

Extragalactic distances

Some repeat

High energy output

What it looks like

Not visible; brief spikes in radio telescope data with a sweep across frequencies.

How it is recognised

Millisecond radio pulses

Dispersion sweep across frequencies

Pulsars repeat regularly within our galaxy

What the second pass must settle

  • Should repeaters be separate entries?
  • How should catalogues be linked?
  • How should origin models be attributed?
