CRE

The astrophysicists did this by combing through the huge data set collected over the course of a decade by the four 12-metre telescopes, applying new, more powerful selection algorithms capable of extracting the CRe from the background noise with unprecedented efficiency.

More specifically, the H.E.S.S. researchers were able to obtain for the first time data about CRe in the highest energy ranges, all the way up to 40 TeV.

"This is an important result, as we can conclude that the measured CRe most likely originate from very few sources in the vicinity of our own solar system, up to a maximum of a few 1000 light years away, a very small distance compared to the size of our Galaxy," explains Kathrin Egberts, from the University of Potsdam, one of the corresponding authors of the study.

Borrowers have struggled to refinance their CRE loans as property values have declined and interest costs have risen.

Other banks' earnings in the past week showed similar challenges facing CRE holdings.
