Another quiet week at the Pole. But there is a bit more “camera” commotion now as the darkest part of the (long) polar night is coming to an end. […]

Week 28 at the Pole
It was a quiet week at the Pole. And just as well…some folks appreciated some time to recover from the Polympics. But the sky was not quiet. […]
IceCube’s Upward Bound class goes virtual
Last week, 52 high school students in Minnesota finished a two-week course taught by IceCube-trained educators. The class was organized by Upward Bound, a federally funded program that provides precollege opportunities for high school students from low-income families whose parents didn’t attend college. […]
Week 27 at the Pole
Here we see IceCube winterover John removing the cover from the IceAct field telescope, while the sky is still grabbing its deserved attention. […]
Searching for neutrino emission from 11 LIGO-Virgo gravitational wave sources
While we have seen neutrinos and electromagnetic radiation with a common origin, researchers have yet to detect neutrinos and gravitational waves coming from the same place. So the IceCube Collaboration recently performed an analysis to look for neutrino emission that correlates with gravitational waves detected by the LIGO and Virgo Collaborations during their first two observing runs, O1 and O2. Their results are described in a paper published today in The Astrophysical Journal Letters. No coincidence was found, but the researchers are already at work on further analyses. […]
Week 26 at the Pole
Word-of-the-day: yukimarimo. New for some, while others may already be familiar with this uncommon word, which refers to tiny, lightweight snowball-tumbleweeds of the Antarctic. […]
Week 25 at the Pole
It was a green sky last week as the biggest aurora storm of the season swept over the South Pole. No long camera exposure needed for this fantastic aurora scene. […]
Sun’s shadow on IceCube shines light on solar magnetic field
The IceCube Collaboration recently performed an analysis to try to expand our understanding of the solar magnetic field by studying the time-dependent cosmic-ray Sun shadow. They also wanted to explore how the cosmic-ray Sun shadow changes at different energy regimes. The results, recently submitted to Physical Review D, show that more solar activity leads to a weaker Sun shadow. There were also indications that, in times of high solar activity, the shadow becomes stronger at higher energies—a hint at Sun-shadow energy dependence that will be explored more in future studies. […]
IceCube at Neutrino 2020
The IceCube Collaboration has a robust cohort presenting at the 29th biennial Neutrino conference, the world’s biggest conference in neutrino physics. Three IceCube collaborators will give plenary talks, and there are 30 virtual posters by collaborators. […]
Week 24 at the Pole
Everything that has a beginning and an end has a middle, too—and that goes for winter. Last week at the South Pole they celebrated midwinter, the marking of the winter solstice. […]
