Dark Energy Survey is out. 29 papers covering 226 million galaxies across 7 billion light-years of space

From Universe Today, May 30, 2021: The Dark Energy Survey camera (DECam) was funded by the Department of Energy (DOE) and was built and tested at Fermilab. The DES took place over 6 years from 2013 to 2019, and looked at over 1/8th of the night sky for a total of 758 night

Einstein’s garden: translating physics into Blackfoot

A piece of ledger paper runs perpendicularly with an ornate, old-fashioned script font, with names and notes. At the top (on the right-hand side of the illustration), the date is 1889. A large button of yellow and blue thin concentric circles with two button holes in the middle overlays the text in the center of paper.

Sharon Yellowfly has been preserving and expanding the Blackfoot language by translating the announcements of LIGO’s universe-bending discoveries.

The Dark Energy Survey presents the most accurate view of the evolution of the universe

From The Florida News Times, May 28, 2021: A highly accurate analysis of the DES data from the first three years of the study, show hints from previous DES data and other important experiments in the universe today are a few percent less than expected. The Dark Energy Survey Camera (DECam) used in the survey was specially designed for the Dark Energy Survey, and was funded by the Department of Energy (DOE) and built and tested at DOE’s Fermilab.

Congressional science panel pushes for more energy research

From Science Magazine, May 27, 2021: The the Biden administration proposed boosting the budget for the Department of Energy’s (DOE’s) basic research wing, the Office of Science, but members of the House Committee on Science, Space, and Technology think the agency needs a lot more. Representative Bill Foster (D–IL), who once worked as a particle physicist at Fermi National Accelerator Laboratory (Fermilab), encourages Secretary of Energy Granholm “to throw deep with major new investments in the sort of large science facilities and initiatives that [DOE] is uniquely positioned to propose, to lead, and to execute.

2 Fermilab scientists receive DOE Early Career Research Awards

On the left, Portrait of a woman smiling beside a microscope in front of a purple background. Her right hand sits on a table and is holding a chip. She wears a mustard-colored floral hijab and fuschia top. On the right, Portrait of a man with dark curly hair and a short beard and mustache wearing glasses, a brown corduroy jacket, a red and blue plaid shirt. His hands are interlaced on the table in front of him. In the lower left corner, the keyboard of a laptop peeks out. He is in front of a starry background.

The DOE’s Office of Science has selected two Fermilab scientists to receive the 2021 DOE Early Career Research Award, now in its 12th year. Farah Fahim and Brian Nord have received the prestigious award, which is designed to bolster the nation’s scientific workforce by providing support to exceptional researchers during the crucial early years.

Dark Energy Survey releases most precise look at the universe’s evolution

The Dark Energy Survey collaboration has created the largest ever maps of the distribution and shapes of galaxies, tracing both ordinary and dark matter in the universe out to a distance of over 7 billion light years. The analysis, which includes the first three years of data from the survey, is consistent with predictions from the current best model of the universe, the standard cosmological model. Nevertheless, there remain hints from DES and other experiments that matter in the current universe is a few percent less clumpy than predicted.

The magnetic anomaly of the muon, also a theoretical challenge

From Pour la Science, May 19, 2021: Is the Standard Model of Particle Physics at fault? The comparison of the first results of the Muon g – 2 experiment on the measurement of the anomalous magnetic moment of the muon and the most recent theoretical results does not yet allow a conclusion.

In the background, trees and a starry night. In the left upper corner, in a bubble similar to a thought bubble in a comic strip, a child reading a book by candlelight.

In recognition of his own past, physicist Azwinndini Muronga has brought STEM enrichment opportunities to youth in remote, underserved towns and villages.

Science corner – journey to the tiniest frontier

From Positively Naperville, May 24, 2021: A report on the April 7 Muon g-2 result announcement speculating that there must be new particles or forces that we have not yet discovered.

This is just the beginning of a discovery that will transform our understanding of the universe

From Quo (Spain), May 23, 2021: An interview with Pilar Hernández Gamazo to find out the scope of the muon case that will transform our understanding of the Universe. Pilar Hernández is a professor of Theoretical Physics at the University of Valencia.
