On April 6, 2023, DiRAC and UW Astronomy participated in the annual Husky Giving Day event. It was another successful drive for support of our student research programs, with more than 20 individual donors raising a total of over $15,000!
We would like to especially recognize the contributions of members of the DiRAC Advisory Board, particularly David Brooks and Jeff Glickman, who have once again been instrumental at supporting this program. We are currently in the process of awarding these 2023 summer research prizes, and we can’t wait to see what amazing research our students pursue.
Last year we were able to launch successful Summer Research Prize program for undergraduates, which was recently profiled by the UW College of Arts and Sciences Newsletter. This year we were aiming to continue the summer undergraduate prize, as well as kick off a new graduate student support program!
This kind of community-driven support is critical for the programs at DiRAC and UW Astronomy. We have one of the largest undergraduate astronomy programs in the nation, and a world-class cohort of graduate students. If you would like to support the work of these amazing young scientists at any level, please consider making a gift!
In Fall 2021, Harish Krishnakumar, then a junior at Tesla STEM high school in nearby Redmond, Washington, reached out to DiRAC Research Scientist Bryce Kalmbach to be his research mentor for a science fair project detecting and studying the properties of ring galaxies in large extragalactic galaxy surveys. Harish’s work eventually took him to the 2022 Regeneron International Science and Engineering Fair where he won two special awards during the competition.
Recently, Harish and Bryce have been working on a paper summarizing their work that has been submitted to the Astronomical Journal and is available on the ArXiv: https://arxiv.org/pdf/2210.11428.pdf.
The work presented in the paper uses convolutional neural networks (CNNs) to identify ring galaxies in postage stamp cutouts of galaxies from the Pan-Starrs 1 survey. CNNs are a commonly used deep learning method for classifying objects in large data sets of images. Since ring galaxies are a rare type of galaxy, one of the challenges of this work was finding enough ring galaxies to train the CNNs. For this, the authors turned to the Galaxy Zoo project which used human volunteers over many months to manually classify galaxy morphological types in images. They also used a technique called transfer learning where the neural networks were trained on a larger set of simulated galaxies before parts of the network were retrained on real data. Understanding and applying computational methods such as CNNs will be necessary to detect ring galaxies and other rare galaxy morphologies in the data provided by existing and future surveys like the Vera Rubin Observatory’s Legacy Survey of Space and Time (LSST). In the end, Harish and Bryce identified 1,151 new ring galaxies after examining over 900,000 galaxies in 10 hours of computation time showcasing a powerful new technique for finding rare morphologies of galaxies in large galaxy surveys.

On March 1st, 2023 DiRAC hosted the first of a series of events “A New Era of Discovery: Mapping the Universe with the Rubin Observatory” at the UW Planetarium.
The interest in the event exceeded all the expectations. The evening was planned around two planetarium shows and many opportunities to hear the latest updates from scientists, postdoctoral fellows, engineers, and students – all contributing in building the largest sky survey in human history.
UW astronomers informed and engaged guests in various topics from the Rubin Alert Distribution System, Asteroid Dynamics & Impacts to the Big Data & Citizen Science.

In the second part of the evening, DiRAC Director, Prof. Mario Juric, acknowledged one of the major donors and a partner, B612 Foundation. He presented Danica Remy, B612 President, with a small token of gratitude after which a former astronaut and the Asteroid Institute Executive Director, Ed Lu, joined the conversation virtually on Zoom.
DiRAC team is energized by the support of its community and plans to continue the momentum of excitement and curiosity especially as we are nearing the Rubin Observatory’s first light in 2024. We will share the knowledge as we learn it and present opportunities to further engagements and events. If you would like to stay in touch and learn about the next event, please email us at dirac@uw.edu
“A New Era of Discovery: Mapping the Universe with the Rubin Observatory”
We’re at the brink of a new age of survey-driven discovery in astronomy. Where before we could only study a handful of objects at a time, new detectors, algorithms, and telescopes will soon allow us – and the entire world – to monitor billions.
The flagship of this era will be the Rubin Observatory, set to open in Chile in late 2024. Rubin will continuously gather data for over 20Bn stars, 20Bn galaxies, with billions of asteroid observations. In importance, it is a ground-based peer of the Webb space telescope.
In about a year, DiRAC researchers, students, and citizen scientists will use Rubin to scan the Solar System for hazardous asteroids, discover interstellar comets, and search for new planets in our Solar System. Our codes will map the Milky Way, detect the most energetic explosions in the universe, and help understand Dark Energy. Our students will learn about astronomy by participating in once-in-a-generation wave of discovery.
We’re looking forward to sharing this with the community of enthusiasts, friends, and supporters who make DiRAC possible.

Program for UW Undergraduate Students
Successfully piloted in 2022, the “Undergraduate Summer Research Prize” for UW undergrads will continue in 2023.
The program will award $3500 to UW undergraduate students working on summer research projects with faculty and staff at UW Astronomy. We are excited to continue this program – Thank you to our ongoing supporters!
Program for UW Graduate Students
Getting engaged with research early in graduate school can fundamentally change a graduate student’s career direction.
This year we are launching a new initiative called the “Jumpstart Research Fellowship”. This program will award $3500 to incoming UW graduate students to enable them to start their research the summer before they arrive at UW – allowing students to focus on research prior to taking classes in the fall.
Such programs have been shown to accelerate and deepen students’ engagement in research, particularly for students from non-traditional pathways.
Our work, from outreach to education to fundamental research, is made possible in no small part by contributions from supporters like you. Thank you for your support; it truly makes a difference!

2023 will be filled with opportunities to share with you our research and enthusiasm while the Rubin Observatory construction is marching towards completion.
DiRAC will host various events and lectures throughout the year. We invite you to join UW astronomers in conversations, ask questions and learn about discoveries we anticipate when Rubin begins its observations.
On March 1st, 2023, we are hosting a Planetarium Experience and Institute Tour called “A New Era of Discovery: Mapping the Universe with the Rubin Observatory”. Join us at this special event to meet our team, and learn what is to come from the most powerful sky survey telescope ever built.
On April 6th, 2023, we will again be participating in the Husky Giving Day! In 2022, we piloted DiRAC Research Prize for Undergraduate Research, a paid summer research opportunity for UW undergraduates that will continue in summer 2023. This Prize was made possible by generous funding provided by DiRAC supporters during the DiRAC Husky Giving Day 2022 campaign. This April, we are excited to expand the HGD participation to all of the Astronomy Department, with an eye on adding another program geared towards incoming graduate students. Those two programs will enhance the experience and offer a unique opportunity to our undergraduate and graduate cohorts.
This will be an important year of transition for us: after nearly a decade of building Rubin, we set our sights on delivering some of the first Rubin science from here at UW. We also continue building algorithms and software needed so everyone can utilize this remarkable dataset, democratizing opportunities with astronomical big data + ML. Our wonderful students, postdocs, staff researchers, and engineers make all these advances possible. They are supported from both public and private sources, including tremendous backing by foundations and individuals from Seattle and the Pacific Northwest. As we ramp-up for Rubin, DiRAC research and discoveries will more than ever be enabled by your continued support. Join us and participate in the next wave of astronomical discoveries from UW. Let’s make the Rubin Observatory a defining astronomical instruments of this decade, together.

This year brought us closer to the first light of the Vera C. Rubin Observatory in Chile. At UW, our team continues to work on algorithms and software, preparing to make discoveries with this great observatory and its Legacy Survey of Space and Time — the LSST.
After eight years of construction, Rubin is nearing completion. In November, we had a rare opportunity to visit the Department of Energy’s SLAC National Accelerator Laboratory with our supporters and friends. There we’ve seen up close the LSST Camera, the largest optical camera in the world sporting over three billion pixels. Seeing the camera for the first time, nearly complete, was a very special occasion for our team: an opportunity to get energized for this last leg of the journey towards LSST. We share the details of the experience in this newsletter.
Throughout the year, DiRAC researchers published numerous scientific papers and appeared in the media. Highlighted in this edition are the coverage of Sarah Greenstreet’s work in the National Geographic and Jim Davenport’s paper on “Searching the SETI Ellipsoid with Gaia”. And earlier this year our researchers’ work also caught the interest of the New York Times, which featured the discovery of 104 asteroids using the THOR algorithm developed by Joachim Moeyens, a graduate student at DiRAC and B612 Asteroid Institute Fellow.
In June, we piloted DiRAC Research Prize for Undergraduate Research, a new paid summer research opportunity for UW undergraduates that will continue in summer 2023. This Prize was made possible by generous funding provided by DiRAC supporters during the DiRAC Husky Giving Day 2022 campaign. And Astronomy on Tap is back! We invite you to check out for yourself this UW graduate-student driven outreach program, have a great night out, and learn about the Universe.
As we close out 2022, we’re looking forward to an exciting 2023. We’ll be wrapping up a number of ongoing research projects, starting many new ones, and also seeing the first light with Rubin. As we do, we look forward to taking you on this journey with us. Plan on joining us for lectures, planetarium shows, and other events that we will be hosting at the DiRAC Institute.
Finally, our work — from outreach, education, to fundamental research — is made possible in no small part by contributions from supporters like you. Thank you for all of your past support; it has truly made a difference. As you consider your charitable donations this year, I hope you will consider supporting the work at DiRAC — enabling our students and postdocs engage in the next generation of discovery!
Thank you,
Mario Juric Director, DiRAC Institute Professor, Department of Astronomy
