Roger David Blandford,

astrophysicist, best known for his work on black holes
.

Early life

Blandford was born in Grantham, England and grew up in Birmingham.[1]

Career

Blandford is famous in the astrophysical community for the

relativistic jets by the extraction of rotational energy from a black hole.[2] The Blandford–Znajek mechanism has been invoked by the Event Horizon Telescope Collaboration to explain the jet power in the first observation of a black hole shadow in the giant elliptical galaxy M87.[3] Blandford also theorized another mechanism for jet formation through hydromagnetic winds launched from accretion disks.[4] In addition to the Blandford–Znajek and Blandford–Payne mechanisms for the formation of relativistic jets, Roger Blandford also helped devise a widely used theoretical model for jet geometric and spectral properties, the Blandford–Königl conical jet model,[5] used to predict radio shifts and low-frequency spectral slopes for optically thick jet cores.[6] He has also made significant contributions to other astrophysical phenomena such as supernovae, by extending the Sedov–Taylor blast wave solution to the ultra-relativistic limit of the Blandford–McKee solution.[5]

In April 2005 he wrote a letter to the astronomy community showing his concern about the

George W. Bush administration US space science policy.[7]

He was also the chair of

Astro2010, the decadal survey that helps define and recommend funding priorities for U.S. astronomy research in the upcoming decade. The Astro2010 report was released 13 August 2010.[8]

Positions

Blandford is a

National Accelerator Laboratory.[10] He was the Pehong and Adele Chen Director, Kavli Institute for Particle Astrophysics and Cosmology from 2003 to 2013.[10][11] He was a co-editor of the Annual Review of Astronomy and Astrophysics (2005–2011).[12][13]
