The South Pole Telescope winterovers are now in their third month of winter at the South Pole. They provided us with some beautiful pictures. Below are pictures of the telescope, the night sky and the aurora:
Here is a little glimpse of life at the South Pole during winter:

7:00 - 8:00 p.m.
Location: The Adler Planetarium, Universe Theater (Chicago, IL)
Presented by Dr. John Carlstrom
We are in the middle of a revolution in our understanding of the Universe. We can finally begin to answer questions such as "How old is the Universe? How did it start? What is the Universe made of? Cosmologists at the University of Chicago have been searching for answers to these questions in one of the most forbidding places on Earth: the high Antartica plateau.

Come talk with Dr. Brad Benson at Café Scientifique!
The Ends of the Earth & the Beginning of the Universe:
The Big Bang, Dark Energy & the South Pole
Presenter: Brad Benson
Time & Date: 7-9 PM
Monday April 23, 2012
Location: The Map Room
1949 N. Hoyne, Chicago, IL
(Limited to first 50 Attendees)
One hundred years ago humans first arrived at South Pole and for the past 20 or so years scientists have traveled there to build telescopes to study the early Universe. These experiments measure light left over from the Big Bang, the cosmic microwave background (CMB). They provide a unique snapshot of the infant Universe at a time when it was only ~400,000 years old, or 0.003% of its current age. These measurements and other evidence tell us that the Universe began with a Big Bang about 14 billion years ago, and that it contains only 4 percent "ordinary" matter (e.g., stars and galaxies, you and me, etc.). The rest of the Universe consists of two mysterious dark components: Dark Matter and Dark Energy. We will discuss evidence for the Big Bang, Dark Matter, and Dark Energy; the latest results from the South Pole, and what its like to work at the bottom of the world.

We are very excited to be taking part in the 2nd USA Science & Engineering Festival in Washington DC April 28-29.
The event is free and held at the Walter E. Washington Convention Center. We've partnered with Bo Rodda's class at the School of the Art Institute in Chicago to meld science and creativity into an exhibit that we hope you'll enjoy.
SPT scientists will be on hand to answer all of your questions about SPT and the science we explore. Hope to see you there!

Here at the South Pole, we are coming up to a very special event: in a week's time, the sun will have set for the next six months. For now, it is still fully above the horizon, but very low. I figured it was appropriate to share some of the last rays of the sun SPT will see as we start our main observing season.

It has been a few weeks since station closing, and aside from our stalwart winterovers, the SPTpol crew is back home and looking at the data streaming north from the telescope. Shown above is an early reduction of the first scan made over the nearby radio galaxy Centaurus A (also known as NGC 5128). It is a temperature map, made using the 90 GHz detectors. Cen A is close enough to Earth that we can actually resolve structure in the galaxy; in SPTpol, we see the center of the galaxy (the blue blob), and the two relativistic jets from the active galactic nucleus (the yellow blobs). Note that this map is flipped around the vertical axis relative to most images you will find on the web. This is still a very rough reduction: the temperature scale isn't calibrated, and the pointing model isn't optimized, but its very exciting to already see the jets with such high signal-to-noise in one observation. The mm-wave emission from the jets is polarized, and we will be using observations of Cen A as part of our polarization angle calibration scheme.

We started hoisting the optics/receiver cryostats into the telescope cabin at 9am on Jan 25, 2012. A mere 39 hours later at 11pm on Jan 26th we achieved first light with SPTpol! Below are detector timestreams as we scan across RCW38, one of the many calibration sources we use. In the next few weeks, we'll be working hard to characterize our instrument. We will make maps of calibration sources, characterize detector response and time constants, map our beams, get the telescope in really good focus for the winter, and measure our detector polarization angles. There is a lot to do to get ready for the observing season, but we're all really excited that we can see astrophysical objects with our new instrument! Congratulations and thanks to everyone who worked so hard to make this instrument possible. Stay tuned for updates!
