Quiz time: This week we’re spotlighting news about ADMX and its recent results.
But first, join Fermilab News at Work in congratulating Abhishek Bakshi for winning last week’s quiz. NOvA scientists detected electron antineutrino appearances in a muon antineutrino beam for a long-baseline experiment at a level of 4.4 sigma. This result indicates that the conclusions of the discovery are unlikely to have happened merely by chance and that the scientists are on their way to a discovery (5 sigma).
Now, show off your knowledge of the news coming out of Fermilab in this week’s quiz. A winner will be randomly selected from all lab employees and users who submit the correct answer to today’s question by noon CT today, Nov. 21.
This week’s question: What did Fritz Zwicky conclude about the mass of Coma galaxy cluster based on its movement? (Hint: See “ADMX experiment places world’s best constraint on dark matter axions.”)
Good luck! We will announce the winner and answer next week. Note that next week’s quiz will be released on Tuesday, Nov. 26, in anticipation of the Thanksgiving holiday.
Past winners are welcome to participate in the quiz each week. However, only one win per person will be recognized in any 30-day period. The winner is recognized in the following week’s quiz and rewarded with a small token.
