A repeating fast radio burst source localized to a nearby spiral galaxy

Nature, 2020
Fast radio bursts (FRBs) are brief, bright, extragalactic radio flashes1,2. Their physical origin remains unknown, but dozens of possible models have been postulated3. Some FRB sources exhibit repeat bursts4–7.

A fast radio burst localized to a massive galaxy

Nature, 2019
Intense, millisecond-duration bursts of radio waves (named fast radio bursts) have been detected from beyond the Milky Way1. Their dispersion measures—which are greater than would be expected if they had propagated only through the interstellar medium of

Extended radio galaxies

Nature, 1977
Observations of extended radio sources are interpreted in terms of a picture for radio source evolution involving multiple ejections of ram pressure confined plasmons in which instabilities lead to the formation of turbulent hot spots and to in situ particle acceleration.

Radio Galaxies and Quasars

Annals of the New York Academy of Sciences, 1974
The discrete sources of radio emission were first distinguished from the general background radiation during the 1940’s as a result of their rapid amplitude scintillations ; and initially, it was thought that the scintillations were due to fluctuations in the intrinsic intensity of the discrete sources. Assuming that the dimensions of the sources could

A census of baryons in the Universe from localized fast radio bursts

Nature, 2020
More than three-quarters of the baryonic content of the Universe resides in a highly diffuse state that is difficult to detect, with only a small fraction directly observed in galaxies and galaxy clusters 1 , 2 . Censuses of the nearby Universe have used

Aligned Radio Galaxies

1991
The discovery of high redshift radio galaxies at z ≤ 4 has unleashed a host of questions about their nature. Many new objects are being found, and their unusual properties are being uncovered. They generally exhibit the “alignment effect”, wherein their highly elongated lumpy morphologies are lined up along the axes of their powerful radio sources ...

Radio Galaxies and Their Environment

2002
In this paper we review the properties of radio galaxies in connection to the effect of the dynamic gaseous environment inside clusters in which they are embedded. The external gas can interact with a radio source in different ways: modifying its morphology via ram-pressure, confining the radio lobes, possibly feeding the active nucleus, enhancing star
