Research, teaching and public engagement in Physics at UW–Madison
The latest results combined weak lensing and galaxy clustering and incorporated four dark energy probes from a single experiment for the first time. This story is amended from one published by Fermilab, which includes information about the full results published by the DES collaboration The Dark Energy Survey (DES) collaboration — including scientists at the …
This post is modified from one originally published by Fermilab In the culmination of a decade’s worth of effort, the Dark Energy Survey collaboration of scientists analyzed an unprecedented sample of nearly 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova …
This story was originally posted by the Graduate School Five outstanding scholars, including Physics PhD student Jimena González, are joining the UW–Madison chapter of the national Edward Alexander Bouchet Graduate Honor Society this academic year. The Bouchet Society commemorates the first person of African heritage to earn a PhD in the United States. Edward A. …
The winners of the UW–Madison 13th annual Cool Science Image contest were announced, and Physics has three winners! Our winners include graduate student Jacob Scott, the graduate student-professor pairing of Jimena González and Keith Bechtol, and alum Aedan Gardill, PhD ’23. Their winning images are below. A panel of experienced artists, scientists and science communicators …
Early in her thesis research, Jimena González was waiting. A lot. To better understand the nature of dark energy, she uses machine learning to search Dark Energy Survey cosmology data for evidence of strong gravitational lensing — where a heavy foreground galaxy bends the light of another galaxy, producing multiple images of it that can …
This news piece has been slightly modified from this news story, first published by Fermilab. 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 more than 7 billion light years. The analysis, …
