Ask Your Questions of Research Team Members John E. Carlstrom,
Dan P. Marrone and Joaquin D. Vieira
The Milky Way today may fire up one new star every year, but billions of years ago, a subset of galaxies in the relatively young universe were producing new stars at a rate of 1,000 per year.
Recently, a multi-national team of astronomers found that these galaxies were churning out stars much earlier than once believed - as early as one billion years after the Big Bang, nearly 13 billion years ago. Now, three members of this team answer your questions about starburst galaxies, the early universe and the research being conducted by the South Pole Telescope and the Atacama Large Millimeter/submillimeter Array(ALMA) in Chile.
- John E. Carlstrom - Subrahmanyan Chandrasekhar Distinguished Service Professor in the Departments of Astronomy and Astrophysics as well as Physics at the University of Chicago, and Deputy Director of the UChicago's Kavli Institute for Cosmological Physics (KICP). Prof. Carlstrom is an observational cosmologist who studies the Cosmic Microwave Background (CMB). He is also leader of the 10-meter South Pole Telescopeproject, which recently completed a survey of 2,500 square degrees of the sky, and is now conducting a survey of the polarization of the CMB.
- Dan P. Marrone - Assistant Professor in the Department of Astronomy at the University of Arizona. Prof. Marrone is interested in galaxy clusters, galaxy formation in the early universe, and the physics of the supermassive black hole in our galaxy, Sagittarius A*.
- Joaquin D. Vieira - Leader of the group studying the galaxies discovered by the South Pole Telescope, Postdoctoral Scholar at the California Institute of Technology and member of Caltech's Observational Cosmology Group. Dr. Vieira is interested in studying galaxy evolution at very high redshifts, the first stars and galaxies, and the evolution of large-scale structures in the universe.
