For more information


Professor Vieira is an observational cosmologist who works across the electromagnetic spectrum. His scientific interests include: the cosmic microwave background, experimental tests of inflation; dark matter; dark energy; gravitational lensing; high redshift galaxies; instrumentation.

He builds experiments, conducts cosmological surveys, and performs observations of the distant Universe. He works with data from the South Pole Telescope, Herschel, Hubble, Spitzer, Chandra, and ALMA.

He is currently helping to build future mm and sub-millimeter facilities, pondering the cosmic evolution of dust and ionized carbon, and working to detect signatures of inflation through polarized measurements of the Cosmic Microwave Background.

Prof. Vieira is currently looking for grad students to work on the following projects:

1) Micro-fabrication of novel photon detectors for astronomy and cosmology.

2) Instrumentation for a new camera for the South Pole Telescope.

3) Analysis of South Pole Telescope survey data.

4) Observations of strong gravitationally lensed galaxies at high-redshift.

Students are welcome and encouraged to drop by with questions about science, instrumentation, or available research projects.

"For decades, astronomers have known that supermassive black holes and the stars in their host galaxies grow together," said co-author Joaquin Vieira of the University of Illinois at Urbana-Champaign. "Exactly why they do this is still a mystery. SPT0346-52 is interesting because we have observed an incredible burst of stars forming, and yet found no evidence for a growing supermassive black hole. We would really like to study this galaxy in greater detail and understand what triggered the star formation and how that affects the growth of the black hole."
