Research Interests

Meng Su is interested broadly in cosmology and high energy astrophysics. He uses gamma-ray/X-ray/microwave/radio observations to study the diffuse emission from the Milky Way, the cosmic ray acceleration and propagation, and the supermassive black hole in the Galaxy. Along with Doug Finkbeiner and Tracy Slatyer, Su has discovered a giant gamma-ray bubble structure in the Milky Way (named, "Fermi Bubble"), which has been selected as one of the top ten physics-related news in 2011 by the American Physical Society. Su has also been studying varies topics in cosmology, including detection of B-mode polarization of the Cosmic Microwave Background (CMB), primordial non-Gaussianity of CMB, gravitational lensing of CMB, cosmic reionization, possible Lorentz violation in the early Universe, and constraining properties of dark energy using various cosmological probes.

Biographical Sketch

Meng Su earned his Ph.D. in Astrophysics from Harvard University in 2012, where he worked with Prof. Douglas Finkbeiner on the discovery of the Fermi bubbles. Meng has also worked with Prof. John Kovac on BICEP, an experiment at the South Pole searching for signatures of primordial gravitational waves on the Cosmic Microwave Background; with Prof. Matias Zaldarriaga on various topics in cosmology; and on the indirect detection of dark matter particles by astronomical observations. Meng received his undergraduate degree in Physics from Peking University in 2007, with a thesis on the cosmological constraints on dark energy. He is from Taiyuan, China.
