Our faculty regularly publish their research in renowed, peer-reviewed journals. Below are some highlights of their most recent publications.
Understanding the afterglow of gamma-ray jets
In collaboration with researchers at Purdue University, and as part of a collaborative NSF research grant, Dr. Barniol Duran has co-authored a paper exploring gamma-ray burst jets. These powerful jets are launched by compact objects and propagate rapidly to large distances, emitting light at various stages. These authors were able to connect the different jet stages and observations within a single model, providing a step forward in understanding this mysterious phenomenon.
The paper was published in the Monthly Notices of the Royal Astronomical Society in August 2023 (Damoulakis, Barniol Duran & Giannios 2023). RBD acknowledges support from the NSF under grant 2107932.
Star clusters in Milky Way-like galaxies
In a collaboration with researchers in the U.K., Dr Pettitt has co-authored a paper investigating how star clusters form in galaxaies similar to our own. Using numerical simulations they found that clusters tend to be larger near to the galactic bar, and smallest in the regions in-between the spiral arms. The image to the right shows three such clusters of stars (white) embedded in their surrounding interstellar gas (artificially coloured green).
The paper is set to be published in the Monthly Notices of the Royal Astronomical Society this August (Ali et al. 2023).
