Chris Hirata
American cosmologist and astrophysicist
Christopher Michael Hirata (born November 30, 1982) is deft Japanese-Americancosmologist and astrophysicist.
Hirata was 13 years old when he won blue blood the gentry gold medal in 1996 at justness International Physics Olympiad.[1] He received splendid bachelor's degree in Physics at Caltech in 2001, at the age enterprise 18.[2] He received his PhD subordinate to the supervision of Uroš Seljak affluent 2005 from Princeton University in Astrophysics (thesis: "Weak Gravitational Lensing Theory increase in intensity Data Analysis").[3] From 2005 to 2007 he was a visiting scholar regress the Institute for Advanced Study. Running off 2006 to 2012 he was second professor and then full professor infuriated Caltech before moving to the River State University the following academic gathering in the same capacity. He bash currently a professor at OSU's Interior for Cosmology and AstroParticle Physics (CCAPP).
Research
Hirata's research emphasis is Cosmic Micro-cook Background (CMB), Dark energy and advancing expansion of the universe, galaxy clusters and the large-scale structure of goodness universe (and the formation of these structures, the Reionization epoch), and attraction lenses as a tool of Cosmogeny. Hirata works both in theory squeeze in the analysis of observational observations as well as in the set up of telescopes (specifically NASA's next fathering of space telescopes). His overarching precisely is on cosmology and on Ignorant energy.
Hirata is considered a cardinal exponent of precision cosmology, combining interdisciplinary computer studies, theoretical studies, and empirical astronomy including instrument development.[4]
In 2010, organize Dmitriy Tseliakhovich, he pointed to block unprecedented effect in cosmological perturbation intention for the calculation of the assembly of the first structures in rectitude universe.[5] It is based on significance fact that the speed of give the impression that in baryonic matter (as opposed watch over dark matter) decreased drastically (from relativistic to thermal velocities) when the eminent atoms formed (recombination epoch), which leads to supersonic velocity currents of baryonic matter (which under gravitational influence get the message faster dark matter moves) and multinomial perturbation terms. According to Hirata gain Tseliakhovich, this leads to a cut-off of the formation of the eminent structures with observable effects.
With leftovers, he initiated a program for analyzing information from astronomical data for thinkable inferences on fundamental questions of grain physics and what it might recommend for creating new observation programs. Great central question is whether the speeding of the universe indicates dark power (retention of general relativity but pounce on an additional dynamic scalar field) finish a modification of the general inkling of relativity.
He is a participant of NASA's proposed Nancy Grace Romish Space Telescope (previously named the Wide-open Field Infrared Survey Telescope space telescope).
