Carlos Argüelles-Delgado named a 2023 Packard Fellow for Science and Engineering

IceCube collaborator and Harvard physics professor Carlos A. Argüelles-Delgado was named a 2023 Packard Fellow for Science and Engineering. Packard Fellowships are given to early-career scientists and engineers “who are boldly pursuing new areas of research.”  As a Packard Fellow, Argüelles will receive $875,000 in unrestricted funds that can be used over five years in […]

Week 40 at the Pole

Last week was another relatively quiet week at the South Pole. IceCube’s winterovers responded to a couple of pages for troubleshooting issues, did the monthly IceTop DOM calibration run, and finished up some tests and preparations for a workstation OS update scheduled for next week. Given a well-behaved detector, the winterovers spent some time outdoors. […]

Week 39 at the Pole

Things were on the quiet side last week at the South Pole. The sun is up but still very low in the sky—check out the long shadow cast by the IceCube Lab (ICL), above. Below, instead, is a nice view of the ICL as it sunbathes in the early sunrise, with sastrugi now visible in […]

Week 38 at the Pole

It was very cloudy for the official sunrise this year. In fact, it was cloudy most of last week at the Pole, as evidenced in the weather balloon photo below, where the white ground blends seamlessly into the white sky. The sun is clearly visible on the horizon in the photo above and the one […]

IceCube search for continuous and transient neutrino emission in the direction of real-time alerts

A cubic-kilometer array embedded in ice, the IceCube Neutrino Observatory detects cosmic messengers called neutrinos that can travel through space uninhibited. Of particular interest are high-energy astrophysical neutrinos, which can be traced back to their sources. IceCube issues real-time alerts to the public within minutes of the detection of a neutrino event with a high […]

Week 37 at the Pole

It’s getting quite bright outdoors, clear enough to see the penguin in front of you—that is, if you happen to be holding a paper version in your hand (or are reading a special comic), as there are no such creatures otherwise found at the South Pole. Even though it’s still cold at the Pole, the […]

Week 36 at the Pole

Even without the stars and auroras, the sky at the South Pole can still steal the show. As the sky brightens ever so slowly during sunrise, the horizon takes on a colorful glow. Above, we have the IceCube Lab (ICL) shown in shadow with a backdrop of orange light stretching along the horizon. Below is […]

Week 35 at the Pole

The skies might be getting a bit brighter as sunrise approaches, but last week at the Pole saw some rapidly dropping temperatures, reaching -100 F over the weekend. That’s not record-breaking, but it is extremely cold nonetheless. Severe cold doesn’t stop winterovers from doing their planned outdoor activities, however. Above, we see them all gathered […]

Week 34 at the Pole

IceCube winterover Marc recently captured a nice swath of green auroras swirling above a bright low moon. It’s likely one of the last aurora photos of the season—as daylight begins to infiltrate the South Pole skies, auroras must be really bright in order to be seen. The images below of the telescopes in the Dark […]

Week 33 at the Pole

The end of winter may be in sight at the South Pole, but the photo above of the IceCube Lab still presents a very wintry scene, all frosted over under a starry sky. The IceCube detector was rather quiet last week, but there was plenty going on at the station. Last week’s firefighting training involved […]
