Julia M. Riley a Fellow of Girton College, works at the Cavendish Astrophysics Group
, University of Cambridge
in the area of radio astronomy
. In 1974, along with Fanaroff, she wrote a famous paper classifying radio galaxies
into two types based on their morphology (shape). These became known as Fanaroff-Riley type I and II radio galaxies (FRI and FRII). In FRI sources the major part of the radio emission comes from closer to the centre of the source, whereas in FRII sources the major part of the emission comes from hotspots set away from the centre (see active galaxies).
Riley lectures and supervises physics within the Natural Sciences Tripos at the University of Cambridge. She is the daughter of British marine geophysicist Maurice Hill and granddaughter of Nobel-prize winning physiologist Archibald Vivian Hill.

Radio astronomy
Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The initial detection of radio waves from an astronomical object was made in the 1930s, when Karl Jansky observed radiation coming from the Milky Way. Subsequent observations have identified a number of...

Radio galaxy
Radio galaxies and their relatives, radio-loud quasars and blazars, are types of active galaxy that are very luminous at radio wavelengths, with luminosities up to 1039 W between 10 MHz and 100 GHz. The radio emission is due to the synchrotron process...
