Sebastian Deffner attends selective quantum science conference in Vatican City

Sebastian Deffner, associate professor of physics, attended “Quantum Science and Technology: Recent Advances and New Perspectives,” a workshop hosted by the Pontifical Academy of Sciences in Vatican City from November 30 to December 2. Deffner was among only about 70 global experts invited to the workshop, and the guest list included numerous Nobel laureates.   “The leading experts in quantum science met in a unique place for a unique workshop to discuss the past, present, and future of quantum technologies,” Deffner says of the workshop. For Deffner, it was an exciting and rare opportunity. The invitation recognizes his leadership role in… Continue Reading Sebastian Deffner attends selective quantum science conference in Vatican City

X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration

“One of the reasons we’re excited about the variability is that there are two main models for how x-rays are produced in these jets, and they’re completely different,” Eileen Meyer explains. “And one of those models is completely incompatible with any kind of variability.” As such, the new findings appear to rule out one leading theory of how particle acceleration works in black hole jets.

Class of 2023 reflects on UMBC as a community that values and supports the whole person

Kayla Tomas ‘23, information systems, maintained a challenging schedule during her undergraduate years. There were days she rose early, studied, and attended classes in the morning and afternoon, headed to volleyball practice in the late afternoon, paused a half hour for dinner, and then dashed off to lead a dance class in the evening. “It was the support of my friends, my family, and the mentors here at UMBC that made it easier,” she says.

UMBC researchers co-author new Science study on how atmospheric dust impacts ocean health

New findings reveal details of the complex relationship between atmospheric dust and vast populations of phytoplankton at the ocean’s surface. These tiny photosynthetic organisms form the foundation of the ocean food chain and play a key role in the global carbon cycle, so the new research will be especially useful as dust patterns shift with climate change.

New UMBC/Los Alamos research on megafire smoke plumes clarifies what they contain, how they move, and their potential impacts

In recent years, large, intense wildfires, known as megafires, have increasingly caused severe damage to forests, homes, and crops. In addition to megafires fatally impacting humans and wildlife alike, they may also be impacting climate change. New research led by UMBC’s Stephen Guimond provides insight into how the large smoke plumes produced by megafires can be more accurately modeled and characterized to improve our understanding of how they might impact the earth.

UMBC researchers listed among the world’s top 2% of most-cited scientists and engineers

More than 40 active UMBC researchers are listed among the top 2% of the world’s most-cited scientists and engineers in an analysis recently published by Elsevier. “This analysis shows that our researchers are truly impacting the scientific community in a significant way,” says Karl V. Steiner, vice president for research and creative achievement. Continue Reading UMBC researchers listed among the world’s top 2% of most-cited scientists and engineers

A Space of One’s Own

On a chilly morning in early spring 2022, Eileen Meyer, Roy Prouty, and Erik Crowe were on the roof of the UMBC Physics Building. They were inside the observatory dome, trying to figure out what had gone wrong with the 32-inch telescope installed when the building was constructed in 1999. They had already determined that the shutters designed to keep dust off the mirrors were jammed, rendering the telescope temporarily unusable. “So we’re up there with flashlights and ladders that are not quite tall enough,” Meyer recalls, “trying to figure out what is happening and realizing that some of the… Continue Reading A Space of One’s Own
