Joanna Dunkley OBE FRS is a British astrophysicist and Professor of Physics at Princeton University. She works on the origin of the Universe and the Cosmic microwave background (CMB) [4] using the Atacama Cosmology Telescope, the Simons Observatory and the Large Synoptic Survey Telescope (LSST). [3] [5]

Contents

Education

Dunkley was educated at North London Collegiate School [1] and the University of Cambridge where she graduated in 2001 with a Master of Science (MSci) degree in Natural Sciences (Theoretical Physics). She was an undergraduate student of Trinity Hall, Cambridge. [6] She moved to Oxford for postgraduate study where she awarded a Doctor of Philosophy degree from the University of Oxford in 2005 for research supervised by Pedro G. Ferreira where she was a postgraduate student of Magdalen College, Oxford. [7]

Research and career

Her research is in cosmology, studying the chronology of the universe using the Atacama Cosmology Telescope, the Simons Observatory, and the Large Synoptic Survey Telescope (LSST). [8] [3] [5]

After her DPhil, she joined Princeton University as a postdoctoral research fellow in 2006, working with David Spergel and Lyman Page on NASA’s Wilkinson Microwave Anisotropy Probe (WMAP). [9] [10] In an interview at Princeton in 2017, Spergel said she quickly "made major contributions to the analysis that led to the development of what we now think of as the standard model of cosmology." [9] Soon after she began working with the European Space Agency (ESA) Planck satellite, [11] which produced a higher-resolution view of the cosmic microwave background (CMB) compared to WMAP. [12]

Dunkley moved to Oxford in 2007 and was promoted to Professor of Astrophysics in 2014. [6] Dunkley led analysis for the Atacama Cosmology Telescope in Chile, using gravitational lensing to identify dark matter. [9] At Oxford her work included constraints on the number of possible neutrino species in the world. [13] The images of the CMB, released in 2013, showed the universe at only 400,000 years old. [14] Her research combines theoretical physics with statistical analysis and uses her models to understand the universe from cosmological observations. [15] Alongside estimating how much the universe weighs, Dunkley can identify the proportions of dark energy and dark matter. [16] She used gravitational lensing within the CMB as evidence for dark energy within the universe, selected by Physics Today as a highlight of 2011. [17]

Dunkley rejoined Princeton in 2016. [18] Her new research, using the Simons Observatory, looks for "new physics, complexities and extra particles that could have existed when the universe was very young,". [19] In 2017, she was awarded the Breakthrough Prize for Physics with 22 members of the NASA WMAP Science Team. [20]

Public engagement

Dunkley has given numerous public lectures and seminars. [21] She has made appearances on BBC Stargazing Live and Dara Ó Briain's Science Club. [22] [23] [24] She is mentioned in Pippa Goldschmidt's I Am Because You Are: An anthology of stories celebrating the centenary of the General Theory of Relativity. [25] Her first book, Our Universe: An Astronomer's Guide was published in 2019. [1] [26] [27] She will deliver a series of workshops and talks for students to raise awareness of women's contributions to astronomy as part of a book tour. [19]

Awards and honours

Dunkley has won several awards and honours including:

Personal life

Dunkley has two children with her partner, the historian Faramerz Dabhoiwala. [2] [1]

<span class="mw-page-title-main">Cosmic microwave background</span> Trace radiation from the early universe

The cosmic microwave background is microwave radiation that fills all space in the observable universe. It is a remnant that provides an important source of data on the primordial universe. With a standard optical telescope, the background space between stars and galaxies is almost completely dark. However, a sufficiently sensitive radio telescope detects a faint background glow that is almost uniform and is not associated with any star, galaxy, or other object. This glow is strongest in the microwave region of the radio spectrum. The accidental discovery of the CMB in 1965 by American radio astronomers Arno Penzias and Robert Wilson was the culmination of work initiated in the 1940s.

<span class="mw-page-title-main">Wilkinson Microwave Anisotropy Probe</span> NASA satellite of the Explorer program

The Wilkinson Microwave Anisotropy Probe (WMAP), originally known as the Microwave Anisotropy Probe, was a NASA spacecraft operating from 2001 to 2010 which measured temperature differences across the sky in the cosmic microwave background (CMB) – the radiant heat remaining from the Big Bang. Headed by Professor Charles L. Bennett of Johns Hopkins University, the mission was developed in a joint partnership between the NASA Goddard Space Flight Center and Princeton University. The WMAP spacecraft was launched on 30 June 2001 from Florida. The WMAP mission succeeded the COBE space mission and was the second medium-class (MIDEX) spacecraft in the NASA Explorer program. In 2003, MAP was renamed WMAP in honor of cosmologist David Todd Wilkinson (1935–2002), who had been a member of the mission's science team. After nine years of operations, WMAP was switched off in 2010, following the launch of the more advanced Planck spacecraft by European Space Agency (ESA) in 2009.

Observational cosmology is the study of the structure, the evolution and the origin of the universe through observation, using instruments such as telescopes and cosmic ray detectors.

<i>Planck</i> (spacecraft) European cosmic microwave background observatory; medium-class mission in the ESA Science Programme

Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013. It was an ambitious project that aimed to map the anisotropies of the cosmic microwave background (CMB) at microwave and infrared frequencies, with high sensitivity and angular resolution. The mission was highly successful and substantially improved upon observations made by the NASA Wilkinson Microwave Anisotropy Probe (WMAP).

<span class="mw-page-title-main">Cosmology</span> Scientific study of the origin, evolution, and eventual fate of the universe

Cosmology is a branch of physics and metaphysics dealing with the nature of the universe, the cosmos. The term cosmology was first used in English in 1656 in Thomas Blount's Glossographia, and in 1731 taken up in Latin by German philosopher Christian Wolff, in Cosmologia Generalis. Religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation myths and eschatology. In the science of astronomy, cosmology is concerned with the study of the chronology of the universe.

The Atacama Cosmology Telescope (ACT) was a cosmological millimeter-wave telescope located on Cerro Toco in the Atacama Desert in the north of Chile. ACT made high-sensitivity, arcminute resolution, microwave-wavelength surveys of the sky in order to study the cosmic microwave background radiation (CMB), the relic radiation left by the Big Bang process. Located 40 km from San Pedro de Atacama, at an altitude of 5,190 metres (17,030 ft), it was one of the highest ground-based telescopes in the world.
