The South Pole Telescope is a 10-meter telescope that has surveyed 2500 square degrees of sky at 1.4, 2.0, and 3.0 mm wavelengths with arcminute resolution and micro-Kelvin sensitivity.  Some of SPT’s main science goals are to understand when and how the first sources (galaxies and quasars) formed and reionized the universe, and to constrain the amplitude and scale dependence of lensing in the CMB in order to improve our understanding of the geometry (dark energy/modified gravity) and growth of structure (in particular the role played by massive neutrinos) of the mid-low redshift universe.

Polarbear is a CMB polarization experiment, currently deploying to the Atacama Plateau in the Chilean Andes. PolarBear could revolutionize cosmology and particle physics by measuring the neutrino mass scale and constraining primordial gravity waves from Inflation, by measuring their signatures in the polarization of the CMB. As a member of PB, my goals are making accurate predictions of the data in order to optimize the scan strategy, and engineering the lensing and inflationary wave B-mode extraction pipelines.

A future satellite mission in ultra-high energy physics, LiteBIRD will measure the Cosmic Microwave Background (CMB) polarization on the entire sky with unprecedented precision. This will revolutionize out understanding of the epochs of inflation and reionization.

The Precision Array for Probing the Epoch of Reionization (PAPER) is a low-frequency radio interferometer designed to detect the ignition of the first stars and galaxies around 500 Million years after the Big Bang.  It uses intensity mapping of 21cm emission of neutral hydrogen at high redshifts (z=7-12) to measure the power spectrum of fluctuations in the intergalactic medium introduced by the first luminous sources in the universe.

The Square Kilometre Array (SKA) is aradio telescope in development in Australiaand South Africa which will have a total collecting area of approximately one square kilometer. It will operate over a wide range of frequencies and its size will make it 50 times more sensitive than any other radio instrument. It will require very high performance central computing engines and long-haul links with a capacity greater than the current global Internet traffic It will be able to survey the sky more than ten thousand times faster than ever before, and produce groundbreaking insights into the Cosmological Parameter budget and the Epoch of Reionization.
