University of Colorado Boulder Physics Professor Jamie Nagle has been awarded the prestigious Distinguished Research Lectureship by the university. This award is among the highest honors bestowed upon a faculty member by their peers, recognizing Nagle's distinguished body of work, academic achievements, and significant contributions to ��Ҵ�ý�ƽ�� educational and service missions.

The Distinguished Research Lectureship is awarded annually to a tenured faculty member, Research Professor, or Adjoint Professor who has been with the university for at least five years. A faculty review panel evaluates nominees, and those selected are invited to present a public lecture highlighting their work. The award recipients receive a $2,000 honorarium and are celebrated for their contributions to ��Ҵ�ý�ƽ�� and the broader academic community.

As a Professor of Physics, Nagle has spent much of his career investigating the early universe through high-energy nuclear physics. His research has focused on understanding the quark-gluon plasma, a state of matter theorized to have existed just microseconds after the Big Bang.

“As you go back to about 6 microseconds after the universe started, the temperature was around two trillion Kelvin,” Nagle explained. “It was theorized that protons and neutrons inside of nuclei would melt away, creating a bath of more fundamental particles—quarks and gluons.”

Nagle's work involves recreating droplets of this quark-gluon plasma in a laboratory setting by colliding large nuclei at nearly the speed of light. These collisions occur at the world’s highest energy accelerators, including the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in New York and the Large Hadron Collider (LHC) in Geneva, Switzerland.

“In the world's highest energy accelerators, we can collide very large nuclei like gold, lead, or platinum at such high velocities that we create a tiny droplet of this 2 trillion Kelvin plasma,” he said.

Reflecting on the award, Nagle expressed deep gratitude and a sense of accomplishment: “It means a lot to me. You get to a certain middle age and are more self-confident, but this recognition feels rewarding. There's a lot of effort, and much of the hard work goes unnoticed. It’s nice to feel like the fruits of that labor are appreciated.”

The Distinguished Research Lectureship also emphasizes communicating complex scientific concepts to broader audiences. For Nagle, this is a vital part of his work: “This award is very meaningful to me because I often listen to the lectures of past recipients. It's about communicating the broader context of why this scientific research is important, not just within the microcosm of nuclear physics.”

Nagle’s lecture is expected to take place in February 2025.

The University of Colorado Boulder hosted the National Nuclear Physics Summer School on campus from July 9-22, 2017. This is an annual two-week series of lectures for graduate students and postdoctoral research scientists in nuclear physics, and is funded by the National Science Foundation. Each summer the school is in a different location, and this year the University of Colorado Boulder nuclear physics group, consisting of Professors Ed Kinney, Jamie Nagle, Dennis Perepelitsa, and Paul Romatschke, applied and were selected to host the school. The school was expertly coordinated by Emily Flanagan of the Physics Department.

The school hosted 50 students from all over the country and even the world - from as far away as Chile, Germany, Israel, the Netherlands, and Armenia, along with 15 lecturers drawn from nuclear physics experts all over the country. Lecture topics covered all areas of nuclear physics from nuclear medicine to neutron star physics, stockpile stewardship, the science of fundamental particles, and more. The nuclear physics faculty at the University of Colorado Boulder study the sub-atomic structure of the proton and the properties of matter that existed at the ultra-high temperatures in the earliest stages of the Universe. Their research is supported by the U.S. Department of Energy and the National Science Foundation. These topics were a particular highlight and area of discussion between students and lecturers.

Every year, approximately 100 Ph.D.s in the United States are awarded in nuclear physics. For these 50 students, the school represents a vibrant way to explore the broad program of nuclear physics research in our country, and learn about the research conducted in the Physics Department here in Boulder.

Brookhaven National Laboratory Receives Approval for Upgraded sPHENIX Detector

Brookhaven National Laboratory has announced that the U.S. Department of Energy recently granted "Critical Decision-Zero" (CD-0) status to the sPHENIX project, a proposed upgrade of the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). This decision paves the way for building a ground-breaking research tool which would have "unprecedented precision for tracking subatomic interactions."

CU Physics Professors Jamie Nagle and Dennis Perepelitsa are research leaders in the new sPHENIX project, and Prof. Nagle previously served as a Co-Spokesperson of the PHENIX detector, which completed its data-taking mission in June 2016. Charged with exploring the interactions between the smallest building blocks of matter, PHENIX parsed collision data from RHIC to study the properties of the quark-gluon plasma, a four-trillion degree primordial soup of fundamental particles thought to have existed microseconds after the
creation of the universe.

The sPHENIX detector will be a significant upgrade to the original PHENIX project. It utilizes a superconducting solenoid magnet repurposed from the Stanford Linear Accelerator Center (SLAC), along with state-of-the-art charged-particle-tracking detectors and new electromagnetic and hadronic calorimeters to greatly enhance the experimental capabilities sPHENIX, allowing it to measure particle jets produced in collisions at RHIC with unparalleled precision and speed.

CU Physicists help reveal secrets of the "perfect fluid" formed in Big Bang

The Relativistic Heavy Ion Collider (RHIC) at the U.S. Department of Energy's Brookhaven National Laboratory has succeeded in creating distinct droplets of the quark-gluon plasma, the material that made up the Universe during the very first moments of the Big Bang. "These experiments are revealing the key elements required for creating quark-gluon plasma," said CU physics professor Jamie Nagle, co-spokesperson for the PHENIX experiment at RHIC.

In 2005, scientists at RHIC (pictured right) observed that gold-gold nuclear collisions created a quark-gluon plasma that acts like a "perfect fluid" which flows nearly without resistance. This experiment collides small nuclei, such as deuterium and helium, with gold nuclei, producing distinct droplets of the quark-gluon plasma in order to measure the properties of the perfect fluid. "RHIC is the only accelerator in the world where we can perform such a tightly controlled experiment, colliding particles made of one, two, and three components with the same larger nucleus, gold, all at the same energy," said Nagle. "This is the way to do good basic science—change just one thing at a time, the number of particles in the ion smashing into the gold nucleus, to test for these interesting geometrical effects."

The analysis of the events (pictured right) reveals that the helium-gold collisions exhibit a triangular pattern of flow that is consistent with the creation of three tiny droplets of quark-gluon plasma.

Nagle and physics assistant professor Paul Romatschke (pictured left) proposed this experiment in 2014. Romatschke's theoretical calculation correctly described the behavior of the droplets in the experiment. "The fact that our predictions were confirmed by experiment seems to suggest that hydrodynamic theory is much more robust than was thought just a few years ago. This is very gratifying," said Romatschke.

"This is a pretty definitive measurement," Nagle said. "We are really engineering different shapes of the quark-gluon plasma to manipulate it and see how it behaves.”

CU Physics Professor Jamie Nagle is a group leader in a new discovery about the quark-gluon plasma. Researchers at the PHENIX detecter at Brookhaven's Relativistic Heavy Ion Collider made an unexpected discovery during an experiment that creates a quark-gluon plasma, the type of matter that existed in the first few millionths of a second after the Big Bang! They found that the quark-gluon plasma can exist in droplets far smaller than previously thought. Professor Nagle is the co-spokesperson for the experiment. Assistant Professor Romatschke's theoretical modeling of the relativistic hydrodynamics of the quark-gluon plasma in highlighted in the press release.
