The Network for Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS), established in 2016 as the first NSF “Hub”, has now become a full NSF Physics Frontier Center (PFC). The NSF PFC award was made effective September 1, 2020.

Headquartered at UC Berkeley, with Wick Haxton as the the overall PI, the new PFC has co-Investigators from several other institutions including: Andre DeGouvea, Northwestern University; Sanjay Reddy, University of Washington; Gail McLaughlin, North Carolina State University; Baha Balantekin, University of Wisconsin Madison; and George Fuller and Tongyan Lin from UC San Diego.

The primary research foci of the N3AS will be on neutrino physics and astrophysics, the origin of the elements, the physics of dense and ultra-dense matter, compact object and early universe physics, gravitational wave and multi-messenger astrophysics, astrophysical simulation and high performance computing, and the nature of dark matter.

The original N3AS Hub had contributions over three years of $2.4M from NSF and $575,000 from the Heising-Simons Foundation. The commitment from NSF for the new PFC will be $10.9M over five years. The N3AS, currently with 8 postdoctoral fellows, will seek to hire 4 fellows per year to conduct research for 3 years. Fellows will spend the first two years at any of the N3AS institutions of their choosing. They will move to a different N3AS institution for year 3. In practice, the fellows collaborate across these institutions, with adequate funding for (in better times) travel. The N3AS website: Read More

Prof. Karin Sandstrom has been selected to receive an Outstanding Mentor Award Karin was nominated by students and selected from a competitive group of faculty from the entire campus. Congratulations Karin!

Astronomers have spotted a massive disk galaxy, not unlike our own, that formed 12.5 billion years ago when our 13.8 billion-year-old universe was only a tenth of its current age. But according to what scientists know about galaxy formation, this one has no business being in the distant universe.

This discovery is challenging how astronomers think about galaxy formation in the early universe.

It's known as Galaxy DLA0817g, but astronomers nicknamed it the Wolfe Disk after late astronomer Arthur M. Wolfe. Read More

CASS' very own E. Margaret Burbidge has been named the Inaugural Fellow of the American Astronomical Society (AAS). Please see the link below. Professor Burbidge is a towering figure in the development of modern astronomy and astrophysics. Her pioneering research in nucleosynthesis, relativistic astrophysics and QSOs/AGN, and novel use of instrumentation has been highly influential. "I know that in many ways her early work brought about the current synergistic relationship between observational astronomy and frontline nuclear and particle physics. Margaret’s scientific accomplishments have served as an inspiration to generations of young astronomers and physicists. As the AAS write-up explains, Margaret also 'broke the observatory gender boundary in the mid-20th century', and this has had very significant positive impact for women in astronomy and physics. We are very fortunate to have her and her legacy in CASS/UCSD," said Prof. George Fuller, CASS Director. Read More

In a paper on “The Origin of Cosmic Rays” just published in the Astrophysical Journal Supplement, Richard Lingenfelter shows how the elemental composition of these relativistic nuclei solves the century old puzzle of the sources and processes of their generation. Studies of their plasma properties have long shown that supernova shocks were their most likely sources, but not what produced their unique mix, nor how their ions are injected into these accelerating shocks. Recent combined abundance measurements and calculations now probe their nuclear, atomic and even solid state processes that answer those questions. They reveal that the cosmic ray mass mixing ratio of supernova ejecta and interstellar medium swept up by these shocks directly define the peak acceleration time. Moreover, in that mix fast grain sputtering injection of suprathermal ions preferentially into those accelerating shocks greatly enriches their composition in heavier elements. This at last matches their unique abundance and reveals even more. Read More

Carl Melis, CASS Associate Research Scientist and co-author of the paper says, "the result concerns a nearby, dusty star that has been considered as both being young with possible terrestrial-like planet building ongoing and as old with possible companion disruption. Our work demonstrates the youth of this source through X-ray and optical observations and also the existence of significant quantities of gas orbiting with the dust. We conclude that this young star is likely in the process of consuming a close-orbiting gas-giant planet." Read More

The Nobel prize in chemistry was awarded for the development of cryo-electron microscopy. The latest technical developments that made the recent breakthrough possible was the introduction of new electron detectors in electron microscopy. Early reports on the use of these sensors for the detection of electrons were presented around the mid-2000s, but these sensors had already been used as a tool in studies of charged particles in other research areas, such as astronomy. This sensor work was pioneered by Dr. Xuong of the UCSD Physics department with the support of CASS engineers Fred Dutweiler and Philippe LeBlanc.

Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis.

As the late Carl Sagan once put it: “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff.”

But what about the heavier elements in the periodic chart, elements such as gold, platinum and uranium?

Astronomers believe most of these “r-process elements”—elements much heavier than iron—were created, either in the aftermath of the collapse of massive stars and the associated supernova explosions, or in the merging of binary neutron star systems.

“A different kind of furnace was needed to forge gold, platinum, uranium and most other elements heavier than iron,” explained George Fuller, a theoretical astrophysicist and professor of physics who directs UC San Diego’s Center for Astrophysics and Space Sciences. “These elements most likely formed in an environment rich with neutrons.” Read More
