Last week was a busy one at the Pole. A lot of holiday preparations and some visitors on station, including folks from Arctic Trucks, getting a station tour and giving tours of their vehicles.

Although fast radio bursts’ (FRBs) progenitors are supposed to be compact and perhaps catastrophic cosmic events that may also produce neutrinos, IceCube has not detected any such neutrinos that could be associated with a known FRB in six years of data. These results are far from precluding the eventual detection of neutrinos from FRBs in the future, but they have set the best limits yet on how many are emitted. The results have been submitted today to The Astrophysical Journal.

There’s always something going on at the Pole, and last week was no different. On the fun side, the winterovers got in some outdoor photography—well, technically indoors for this shot of the icy stairwell down in the fuel arches

The many flight delays this season affected the arrival of not only personnel but cargo, too. It eventually showed up though, and last week IceCube’s winterovers were busy managing it all at the IceCube Lab. It was a lot of carrying, and it was exhausting, but they were still smiling after it was all said and done

In a study published today in the journal Physical Review D, HAWC announces a measurement of the cosmic-ray energy spectrum in the energy range of 10 to 500 TeV, bridging measurements at higher energy usually performed by ground based detectors and measurements at lower energy that previously had been conducted by detectors on satellites and balloons.

It was a busy week for IceCube’s newest winterovers. A plane arrived after a long hiatus, bringing some new folks to the station and taking away last year’s winterovers, finally. But much of the excitement came from alarms going off—the ones for fire were false alarms thankfully. But it gave the new winterovers a chance to apply their training to emergency response operations.https://en.wikipedia.org/wiki/Sun_dog

Last week kept IceCube’s newest winterovers busy, but not too busy, with a number of activities. Johannes was on call, and got his first page to deal with a detector issue, but not too big of a problem. Both winterovers were trained on the PistenBully, or snowcat, and then drove around to the IceTop stations to take snow height measurements.

In a critical measurement that may one day help predict new physics beyond the Standard Model of particle physics, an international team of researchers with the IceCube Neutrino Observatory has shown how energized neutrinos can be stopped cold as they pass through the Earth. The new measurement is reported today in the journal Nature.

Flight canceled? Well, that happens. But, canceled … again? Welcome to plane travel at the Pole. The changeable weather patterns in the harsh climate of Antarctica make flights in and out susceptible to delays. It’s part and parcel of the whole experience.

The HAWC Collaboration has made the first detailed measurements of two pulsars touted as possible sources of the positron excess observed in 2008 by the spaceborne detector AMS-02. By catching and counting particles of light streaming forth from these nearby stellar engines, reserachers have showed that these two pulsars are very unlikely to be the origin of the excess. The results are published today in Science.
