Professor Daniel Anglés-Alcázar research featured in ‘UConn Today’ and CBC radio interview

At the center of galaxies, like our own Milky Way, lie massive black holes surrounded by spinning gas. Some shine brightly, with a continuous supply of fuel, while others go dormant for millions of years, only to reawaken with a serendipitous influx of gas. It remains largely a mystery how gas flows across the universe to feed these massive black holes. UConn Assistant Professor of Physics Daniel Anglés-Alcázar, lead author on a paper published in The Astrophysical Journal, addresses some of the questions surrounding these massive and enigmatic features of the universe by using new, high-powered simulations.

For more details, please check the article in UConn Today, and Prof. Anglés-Alcázar’s recent radio interview by Canadian Broadcast Corporation.

Professor Cara Bettersby’s research is featured in the article “The Study of Big Data: How CLAS Researchers Use Data Science” published by UConn Today.

Prof. Battersby’s work focuses on describing and studying the center of the Milky Way galaxy, which she calls an “experimental playground” for the distant cosmos. Her work described the spectroscopy of the galaxy’s center, which analyzes imagery to understand the chemical makeup of the area, as well as its temperature and the velocity of objects.

Battersby works on data from the Submillimeter Array facility, a collection of eight powerful telescopes situated atop Mount Maunakea in Hawaii. The telescope can collect up to a terabyte of data every day, and Battersby’s project used 61 days of data.

Battersby refers to her computer as “her laboratory,” and ensures the students in her classes do, too. In her courses, she often assigns programming and analysis problems, like using a large data set to determine the material composition of the Sun.

“We have a lot of the tools to train students in data science,” she says. “Research is moving in that direction, and students in our programs are prepared for it.”

Cancelled: Professor Donna Strickland , Katzenstein Distinguished Lecturer

 

Dear Friends of UConn Physics,

Due to the current health situation and concerns surrounding the Corona virus, we are canceling the Katzenstein Lecture and Banquet scheduled for Friday, March 13, 2020.

It was an agonizing decision to cancel, but our first priority is the health of all who would have been attending, our special guest Professor Strickland, and the UConn community. I extend an extra apology for those of you who have planned to travel a considerable distance and will need to change plans. For those who have signed up for the banquet, we are working to arrange refunds.

If all goes well, the current health crisis will be behind us soon and we will see if we can reschedule Professor Strickland for another, safer time.

Again, my apologies and best wishes,

Professor Jocelyn Bell Burnell – 2019 Katzenstein Lecturer

The UConn Physics Department is delighted to announce that our 2019 Distinguished Katzenstein Lecturer will be

Professor Dame Jocelyn Bell Burnell

Storrs Campus, Student Union Theater

Professor Dame Jocelyn Bell Burnell (pictured at left) is world-famous for her discovery of pulsars in 1967. Pulsars are a special type of neutron star, the rotating dense remnant of a massive star. Pulsars have highly magnetic surfaces and emit a beam of electromagnetic radiation along their poles. This beam of light moves into and out of our line-of-sight at quick, constant intervals, appearing as a regular “pulse” of light.

At the time of this discovery, Bell Burnell was a graduate student at the University of Cambridge and worked with her supervisor, Anthony Hewish, to construct the Interplanetary Scintillation Array to study another class of objects called quasars. In the course of her daily detailed analysis, she noticed a strange “pulsing” signal in her data. Jokingly dubbed “Little Green Man 1” (LGM-1), further data-taking and analysis revealed this signal to be rapidly spinning neutron star, eventually dubbed a “pulsar.”

Bell Burnell’s discovery is considered one of the most important achievements of the 20th century and was recognized by a Nobel Prize in Physics in 1974, awarded to her supervisor Anthony Hewish as well as to astronomer Martin Ryle. While many condemned the omission of Bell Burnell for the award, she rose above, graciously stating, “I believe it would demean Nobel Prizes if they were awarded to research students, except in very exceptional cases, and I do not believe this is one of them. Finally, I am not myself upset about it – after all, I am in good company, am I not!”

Professor Dame Jocelyn Bell Burnell has a highly distinguished career. Some notable highlights include serving as head of the Royal Astronomical Society and as the first female president of both the Institute of Physics and The Royal Society of Edinburgh. She was appointed Dame Commander of the Order of the British Empire for services to astronomy in 2007. Her story has been featured in a number of works, including the BBC Four’s Beautiful Minds and BBC Two’s Horizon. Bell Burnell is currently the chancellor of the University of Dundee in Scotland and a visiting professor of astrophysics at the University of Oxford.

In 2018 Bell Burnell was awarded a Special Breakthrough Prize in Fundamental Physics. Only four such prizes have been awarded, one to Stephen Hawking, one to the CERN scientists who discovered the Higgs Boson, and one to the LIGO team for their detection of gravitational waves. This award recognizes her discovery of pulsars and “a lifetime of inspiring scientific leadership.” In addition to her research accolades, her teaching, leadership, and work to lift up women and minorities in science is without parallel.

Research Spotlight: Exploring the nature of the universe with Dr. Thomas Blum

The Daily Campus published an article highlighting the research of Prof. Thomas Blum about Quantum Chromodynamics, a theory which describes the interactions between elementary particles. The development of this theory could help further understanding of the Standard Model of particle physics. The Standard Model is what physicists use to describe the fundamental building blocks of everything in the universe.
