Solar Eclipse Viewing Event: 2-4:30pm Mon Apr 8 on Horsebarn Hill

Posted on by

UConn faculty and students will host a community event to view the solar eclipse at 2:00-4:30pm this Monday, April 8, on Horsebarn Hill (behind the Dairy Bar). Here in Storrs we’ll observe a maximum occultation of 92% at 3:28pm. This is a very exciting and special opportunity, since the next time that our location will experience such an eclipse is not until 2079(!).

Details about the event are in the flyer embedded below, and also on the UConn Events Calendar. You can also listen to Prof. Jonathan Trump talk more about the solar eclipse on WILI-AM and on NBC CT.

Prof. Jonathan Trump Interviews about the James Webb Space Telescope

Posted on by

The James Webb Space Telescope released its first science observations on July 12 with much fanfare and excitement across the globe. UConn Physics Professor Jonathan Trump is part of the Cosmic Evolution Early Release Science collaboration that was awarded some of the first observations on the transformative new space telescope.

Prof. Trump was interviewed by several local media outlets, including NPR CT, WILI AM, and the Waterbury Republican-American, about the new James Webb Space Telescope observations and his research goals for the telescope. UConn Today also featured a story about the early JWST observations and scientific findings produced by Prof. Trump’s research collaboration.

Prof. Cara Battersby Awarded an NSF CAREER grant

Posted on by

Cara Battersby CAREER AwardProfessor Cara Battersby has been awarded an NSF CAREER grant! “The Faculty Early Career Development (CAREER) Program is a Foundation-wide activity that offers the National Science Foundation’s most prestigious awards in support of early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organization.”

Prof. Battersby’s CAREER Award is entitled “CAREER: Shining STARs Amidst the Turbulence” and is an ambitious project to complete the first-ever systematic study of turbulence in an extreme environment, the center of our galaxy. Turbulence is poorly understood yet plays a pivotal role in the setting the Initial Mass Function (IMF), which underpins all of modern astrophysics. The results from this research will be brought into under-resourced high school classrooms through lesson plans jointly developed by K-12 teachers and undergraduate students from traditionally under-represented groups. Battersby aims to recruit and retain students from under-represented groups in STEM through a new mentorship program UConn-STARs.

Plates that Helped Map the Universe, Now at UConn

Posted on by

UConn is now home to tools that have played an instrumental role in mapping the universe — 10 large aluminum plates used as part of the Sloan Digital Sky Survey (SDSS). Measuring 32 inches across, one-eighth of an inch thick, and with thousands of tiny holes drilled in them, these plates may not be the type of instruments most people would initially picture; however, they have helped answer important questions about the universe.

Jonathan Trump, associate professor of physics, helped design the final round of plate observations for SDSS, which observed over three million objects in the sky, including stars, galaxies, and supermassive black holes from a telescope in New Mexico.

For more information, see the full UConn Today story here. This story was also featured in May edition of Connecticut Magazine (page 32).

Research of UConn Professor Daniel Angles-Alcazar featured in UConn Today

The article The Largest Suite of Cosmic Simulations for AI Training Is Now Free to Download; Already Spurring Discoveries describe research of a team of astrophysicists that includes UConn Professor of Physics Daniel Anglés-Alcázar.

“Machine learning is revolutionizing many areas of science, but it requires a huge amount of data to exploit,” says Anglés-Alcázar. “The CAMELS (which stands for Cosmology and Astrophysics with MachinE Learning Simulations) public data release, with thousands of simulated universes covering a broad range of plausible physics, will provide the galaxy formation and cosmology communities with a unique opportunity to explore the potential of new machine-learning algorithms to solve a variety of problems.”

Prof. J. Trump interview about the launch of the James Webb telescope

Posted on by

UConn Physics Professor Jonathan Trump is part of a group of scientists who will be the first to conduct research using the James Webb space telescope. The local Fox News TV station conducted an interview with Prof. Trump.

The James Webb Space Telescope (JWST) was launched on December 25, 2021. The telescope is named after James E. Webb who was the administrator of NASA from 1961 to 1968 and played an integral role in the Apollo program. JWST is intended to succeed the Hubble Space Telescope as NASA’s flagship mission in astrophysics. It is designed to provide improved infrared resolution and sensitivity over Hubble, viewing objects up to 100 times fainter, and will enable a broad range of investigations across the fields of astronomy and cosmology.

U.S. Senators introduce a resolution to recognize the Arecibo Observatory Telescope

On Friday December 3rd, a group of U.S. Senators, Richard Blumenthal (D-CT), Edward J. Markey (D-MA), Marco Rubio (R-FL), Elizabeth Warren (D-MA), and Rick Scott (R-FL) introduced a bipartisan a resolution to recognize the significant scientific, educational, and economic contributions made by the Arecibo Observatory telescope.

“The telescope at Puerto Rico’s Arecibo Observatory was a scientific marvel, extensively expanding our understanding of the universe,” said Blumenthal. “Its collapse left a significant educational void for our country and the scientific community across the world. I’m proud to recognize its important contributions alongside my colleagues and express our strong support for further studies for how best to replace—and build upon—this telescope’s capabilities at the world-class Arecibo Observatory.”

Prof. Chiara Mingarelli awarded NSF grant

Posted on by

Chiara Mingarelli, Assistant Professor of Physics at UConn, is the lead researcher on a $650,000 Collaborative Research Grant from the National Science Foundation, half of which is earmarked for UConn, to conduct an experiment to prove the existence of supermassive black hole binaries. This grant will combine, for the first time, traditional astronomy with gravitational wave astronomy.

“This project is really setting up a whole new way to think about low-frequency gravitational-wave and extragalactic astronomy,” Mingarelli says. “With our new method, not only can we make predictions about the amplitude of the gravitational wave background, but we can also make predictions of where the likeliest and closest supermassive black hole systems are.”

A Physics Ph.D. Student’s Step-By-Step Journey to Storrs and Distant Galaxies

Posted on by

UConn Physics graduate student Mohammed (Mo) Akhshik works on data gathered using the Hubble Space Telescope (HST) and has led to exciting discoveries, some while he served as the science Principle Investigator of the REQUIEM HST program from which he is co-author on two publications, one in Nature and one in Nature Astronomy. Akhshik is also a recipient of a national fellowship as a NASA FINESST Future Investigator.

Akhshik gleans new information about very distant galaxies using a phenomenon called gravitational lensing. Due to the forces of gravity, light from distant galaxies is focused to appear brighter, and the images appear in different parts of the sky at different times, explains Akhshik. The researchers were also able to detect new details of distant galaxies through observations from different telescopes, which Akhshik says is almost like layering different filters on the same image.

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.
