Dear Astro-Lunchers,
After a long Spring Break, we are ready to have our AstroParticle Lunch back at 11:45 am (EST) tomorrow!
This week, we are very happy to have Kayla Leonard(UW–Madison) as our guest speaker. She will go through her work on the low energy event reconstruction in IceCube.More information is provided below:
Title: Low Energy Event Reconstruction in IceCube DeepCore
Abstract:
The reconstruction of event-level information, such as the direction or energy of a neutrino interacting in IceCube DeepCore, is a crucial ingredient in many physics analyses. Algorithms to extract this high-level information from the detector’s raw data have been successfully developed and used for high-energy events. In this work, we address unique challenges associated with the reconstruction of lower energy events in the range of a few to hundreds of GeV and present two separate, state-of-the-art algorithms. One algorithm focuses on the fast directional reconstruction of events based on unscattered light. The second algorithm is a likelihood-based multipurpose construction offering superior resolutions, at the expense of larger computational costs.
After Kayla’s presentation, Ivan will introduce either a paper on the ultra-high-energy photon flux from the Galactic disk 2203.08751 or explore the chemical composition of the ultra-high energy cosmic ray by cross-correlations 2203.09538.
We continue to hold the AstroParticle Lunch in the Price Place + Zoom mode, with the Zoom link is now available on our website: https://sites.google.com/site/ccappastrolunch/.We look forward to seeing you all soon!
