Jamie S. Farnes (born 1984) is a British cosmologist, astrophysicist, and radio astronomer based at the University of Oxford. He studies dark energy, dark matter, cosmic magnetic fields, and the large-scale structure of the universe. In 2018, it was announced by Oxford that Farnes may have simultaneously solved both the dark energy and dark matter problems, using a new negative mass dark fluid toy model that "brings balance to the universe".[1][2]
In 2019, the Farnes Universe was listed as one of the top 10 dark matter candidates.[3]
Farnes was born in Cornwall, England, UK. He attended Saltash Community School, studied at Royal Holloway graduating with a BSc with first class honours in theoretical physics (2008), followed by a PhD in astrophysics from the Cavendish Laboratory at the University of Cambridge (2012). Farnes was also a member of the Kavli Institute for Cosmology and studied at Trinity Hall College where Stephen Hawking had previously completed his PhD.
Career
From 2012 to 2015, Farnes was an Associate Lecturer at the University of Sydney and within the ARC Centre of Excellence for All-Sky Astrophysics. In 2015 he briefly moved to the Arcetri Astrophysical Observatory, before he took up an appointment as an Excellence Fellow at Radboud University Nijmegen.
In 2017, he moved back to the UK as a Research Associate at the Oxford e-Research Centre within the Department of Engineering Science at the University of Oxford.
In 2019, it was reported that Farnes has since moved on to Faculty, a leading Artificial Intelligence company.[4]
Farnes' current work is on the development of science pipelines for the Square Kilometre Array, a next-generation radio telescope that will generate 5 zettabytes (5 million petabytes) of data each year – a data rate equivalent to 5 times the estimated global internet traffic in 2015. Farnes is a member of two SKA Science Working Groups.[5][6]
Farnes is also a member of the Executive Committee for the POSSUM survey with the Australian Square Kilometre Array Pathfinder,[7] on the Board of the Very Large Array Survey Science Group and co-chair of the Extragalactic Working Group to map the radio universe,[8] and a core member of the LOFAR telescope based in the Netherlands[9] He is engaged in public engagement and has written articles for The Conversation,[10] communicated his work in interviews over the Periscope platform,[11] and previously run the CAASTRO in the Classroom program funded by the Australian Research Council.[12][13]
Research
In 2014, Farnes created a "rainbow of radio data" to solve a problem about whether magnetic fields in space are intrinsic to radio-wave emitting galaxies or quasars, or whether they are much closer to Earth—in intervening gas clouds. Farnes and his colleagues were able to show that the magnetic field is usually related to the galaxy or quasar itself and were able to discern the different effects of the core of the galaxy or quasar, and of its radio-emitting 'lobes'.[14]
In 2015, he and Bryan Gaensler calculated that the cosmic magnetic fields in ancient galaxies are much stronger than was previously believed, requiring "magnetic fields to be the same strength 7 billion years ago as they are today"[15] In 2017, the American Astronomical Society announced that Farnes had used the Very Large Array to make the first detailed study of the evolution of protogalaxies in the early universe and came up with a creative alternative which suggests that a more exotic dynamo theory must be at play throughout the cosmos.[16]
In 2018, it was reported across international media that Farnes may have solved the mystery of dark energy and dark matter by unifying them into a dark fluid with negative mass. This work reinvoked the creation tensor previously suggested by Fred Hoyle, but only for negative masses.[17][18][19][20][21][22][23][24][25][26][27]
