Awards and Honors
Sau Lan Wu honored with named planet
Posted on
The International Astronomical Union (IAU) has named a minor planet ‘Saulanwu’ after UW–Madison physics professor Sau Lan Wu.
The planet (177770) ‘Saulanwu’ (=2005 JE163) was discovered on May 8, 2005 at Mt Lemmon observatory in southern Arizona by a NASA funded project, the Catalina Sky Survey. More details about the planet can be found from NASA’s JPL website, including a sketch of the planet’s orbit, which is in the asteroid belt between Mars and Jupiter. Minor planet ‘Saulanwu’ is about two kilometers in diameter, and it takes four years to orbit the sun once. This planet is relatively stable, dynamically, and is expected to remain in our cosmos for millions of years to come.
Wu was nominated for this honor by astronomer Gregory J. Leonard from the University of Arizona’s Department of Planetary Sciences.

Victor Brar
Sixteen projects — including two from Physics — have been selected for funding in the second round of Research Forward, a program to stimulate innovative and groundbreaking research at UW–Madison that is collaborative, multidisciplinary and potentially transformative.
The winning projects were chosen from 96 proposals submitted by applicants across campus. The Research Forward initiative is sponsored by the Office of the Vice Chancellor for Research and Graduate Education and is supported by the Wisconsin Alumni Research Foundation, which provides funding for one or two years, depending on the needs and scope of the project. Some of the projects that have been funded have the potential to fundamentally transform a field of study.

The Research Forward initiative is sponsored by the Office of the Vice Chancellor for Research and Graduate Education and is supported by the Wisconsin Alumni Research Foundation, which provides funding for one or two years, depending on the needs and scope of the project. Some of the projects that have been funded have the potential to fundamentally transform a field of study.
“Research Forward encourages collaboration among campus PIs, enhances PhD student and postdoc training, and strengthens our external grant funding requests,” says Steve Ackerman, vice chancellor for research and graduate education. “The projects we selected are truly forward-looking and use innovative approaches and tools such as state-of-the-art machine learning methods, 3D printing techniques and geostationary satellites.”
The Physics projects are:
Multiscale Photonic Structures for Complete Opto-Electronic Control of Light, Victor Brar, assistant professor of physics. This project will lead to creation of a crucial electrical component for holographic displays, high-resolution biomedical imaging, and laser-based range finders valuable for self-driving cars.
Reconstructing the Big Bang with Physics-Guided Machine Learning, Moritz Muenchmeyer, assistant professor of physics. Physicists and computer scientists will develop a new technique to look back in time and reconstruct what happened at the Big Bang, aided by recent developments in machine learning. Gary Shiu is a co-PI of this award.
Keith Bechtol selected to Department of Energy Early Career Research Program
The funding will allow Bechtol and his group to first work on commissioning the Vera C. Rubin Observatory in preparation for the Legacy Survey of Space and Time (LSST), then they will transition to data collection and analysis for their cosmology research.
“We are anticipating that LSST will catalog more stars, more galaxies and more solar system objects during its first year of operations than all previous telescopes combined,” Bechtol says.
Rubin Observatory’s telescope will have an eight-meter diameter mirror and a ten square degree field of view. The 3.2-billion-pixel camera will collect an image every 30 seconds. All told, LSST will amass around 10 terabytes of data every night.
Bechtol has leadership roles for building and commissioning the observatory as well as with the Dark Energy Science Collaboration (DESC), the international science collaboration that will make high accuracy measurements of fundamental cosmological parameters using LSST data. At least seven other collaborations have formed around different science areas to analyze the data. Rubin Observatory is preparing to serve the LSST data to many thousands of scientists in the US, Chile, and at international partner institutions around the world.
“DESC will use LSST data to address several outstanding physics questions, such as: Why are the distances between galaxies growing at an accelerating rate? What is the fundamental nature of dark matter? What is the absolute mass scale of neutrinos? How did the universe begin and what were the initial conditions?” Bechtol says.
Bechtol will receive around $150,000 per year for five years to cover summer salary and research expenses. The research expenses will be used mostly to cover the analyses after the data collection starts. However, because there cannot be useful data without the initial commissioning and science validation steps — and because the Observatory is still a couple of years away from first light — the DOE award is also supporting Bechtol’s efforts during the commissioning phase to accelerate the realization of DESC science goals.
“For me, the most important thing about this award is that it will provide more opportunity for students and postdocs to directly contribute to this ambitious experiment. Turning on a new experiment of this scale and complexity doesn’t happen every day,” Bechtol says. “For my research group to be able to participate firsthand in the commissioning, seeing first light, and contributing to the first cosmology results is so valuable from a career development perspective. We are training the next generation of experiment builders.”
The DOE early career program is open to untenured, tenure-track professors at a U.S. academic institution (or a full-time employee at a DOE national laboratory) who received a PhD within the past 10 years. Research topics are required to fall within one of the DOE Office of Science’s eight major program offices, including high energy physics, the program through which Bechtol’s award was made.

Thad Walker
Extraordinary members of the University of Wisconsin–Madison faculty, including physics professor Thad Walker, have been honored during the last year with awards supported by the estate of professor, U.S. senator and UW Regent William F. Vilas (1840-1908).
Walker was one of seventeen professors were named to Vilas Distinguished Achievement Professorships, an award recognizing distinguished scholarship as well as standout efforts in teaching and service. The professorship provides five years of flexible funding — two-thirds of which is provided by the Office of the Provost through the generosity of the Vilas trustees and one-third provided by the school or college whose dean nominated the winner.
In addition, nine professors received Vilas Faculty Mid-Career Investigator Awards and six professors received Vilas Faculty Early Career Investigator Awards.
Thirty-two members of the University of Wisconsin–Madison faculty — including physics professor Mark Saffman — have been awarded fellowships from the Office of the Vice Chancellor for Research and Graduate Education for 2022-23. The awardees span the four divisions on campus: arts and humanities, physical sciences, social sciences and biological sciences.
“These awards provide an opportunity for campus to recognize our outstanding faculty,” says Steve Ackerman, vice chancellor for research and graduate education. “They highlight faculty efforts to support the research, teaching, outreach and public service missions of the university.”
The awards are possible due to the research efforts of UW–Madison faculty and staff. Technology that arises from these efforts is licensed by the Wisconsin Alumni Research Foundation and the income from successful licenses is returned to the OVCRGE, where it’s used to fund research activities and awards throughout the divisions on campus.
Mark Saffman was awarded a WARF professorship. These professorships come with $100,000 and honor faculty who have made major contributions to the advancement of knowledge, primarily through their research endeavors, but also as a result of their teaching and service activities. Award recipients choose the names associated with their professorships. Saffman, the Johannes Rydberg Professor of Physics and director of The Wisconsin Quantum Institute, first began work on atomic physics and initiated a long-term effort to develop quantum computers. He is known for his research as a leader in the ongoing development of atomic quantum computers based on the Rydberg blockade mechanism.
In addition, physics affiliate professor Mikhail Kats received a Romnes Faculty Fellowship.

Overall, forty-five textbooks have been awarded 2022 Textbook Awards by TAA. 12 textbooks received William Holmes McGuffey Longevity Awards, 13 textbooks received Textbook Excellence Awards, and 20 textbooks received Most Promising New Textbook Awards.
The awardees were recognized during an awards ceremony today, April 27.
A testimony in support of the award for Physics in the Arts says:
“Physics in the Arts is the third edition of a textbook which makes physics intriguing and even fun. It is a great effort in connecting complex physics principles with procedures and activities of artists. As artists and artisans, we create and share the beautiful through light and sound. For those of us interested in the aesthetic side of life, this book shows how a physical understanding of light and sound can expand and deepen our appreciation of the world opened up by these media. Understanding the concepts and connections of the book make their professional lives more fulfilling and more efficient.”
Four University of Wisconsin–Madison students have been named winners of 2022 Barry Goldwater Scholarships, one of the most prestigious awards in the U.S. for undergraduates studying the sciences.
The UW–Madison winners are sophomore Lucy Steffes and juniors Sarah Fahlberg, Elias Kemna and Samuel Neuman.
Each university in the country may nominate up to four undergraduates for the annual award. To have all four candidates win is remarkable, says Julie Stubbs, director of UW’s Office of Undergraduate Academic Awards.
Lucy Steffes is a sophomore from Milwaukee, double-majoring in astronomy-physics and physics with a certificate in German. Her freshman year, Steffes began working with astronomy professor Snezana Stanimirovic on the ALMA-SPONGE project, for which she co-authored two papers recently published in the Astrophysical Journal. The project looks at molecular formation in the interstellar medium to describe potentially star-forming regions. At the end of her freshman year, Steffes earned a Hilldale Undergraduate Research Fellowship to calculate the upper limits of molecular detections in the Magellanic Stream. She spent last summer working at the Green Bank Observatory in West Virginia examining the chemical composition and evolution of two globules in the Helix Nebula. This summer, she will be returning to the observatory to examine neutral atomic carbon across the Helix Nebula. She plans to pursue a Ph.D. in astrophysics.
