INPA Seminar Speaker: Ralf Konietzka (Harvard) - Title: Fast Radio Burst Cosmology in IllustrisTNG: Forward Modeling Dispersion Measures to Constrain Baryonic Feedback
2026-01-16 12:00 - 13:00
Date: January 16, 2026
Time: 12:00 pm – 1:00 pm

Speaker: Ralf Konietzka (Harvard)
Title: Fast Radio Burst Cosmology in IllustrisTNG: Forward Modeling Dispersion Measures to Constrain Baryonic Feedback
Abstract: The dispersion measures (DMs) of Fast Radio Bursts (FRBs) arise predominantly from free electrons in the large-scale structure of the Universe. The increasing number of FRB observations have started to empirically constrain the distribution of cosmic baryons, making it crucial to accurately forward model their propagation within cosmological simulations.
In this talk, I present a method for measuring FRB DMs in IllustrisTNG that continuously traces rays through the simulation while reconstructing all traversed line segments within the underlying Voronoi mesh. Leveraging this technique, we create over 20 publicly available DM catalogs, including a full-sky DM map observed from a Milky Way-like environment.
Our method addresses a problem in previous TNG-based studies, in which a sparse snapshot sampling in the path integral leads to a misestimation of the standard deviation and higher moments of the DM distribution p(DM|z) by over 50%.
Confronting our simulated FRB catalogs with recent observations from DSA-110, ASKAP, and CHIME, I quantify the distribution of baryons relative to the underlying matter, allowing us to place new constraints on the strength of baryonic feedback.

INPA Seminar Speaker: Seungeun Lee (LBL)- Title: Scintillation photon counting detector concept for advancing time-of-flight PET
2026-01-30 12:00 - 13:00
Date: January 30, 2026

Title: Scintillation photon counting detector concept for advancing time-of-flight PET
Abstract: Positron emission tomography (PET) is a powerful imaging modality for providing in vivo molecular function in nuclear medicine. The precise timing capability of positron annihilation photon interaction within the scintillation detectors has remarkably revolutionized the diagnostic performance of PET, motivating the radiation instrumentation researchers to pursue sub-100-ps time resolution at the system level. The biomedical imaging team at LBL ANP is currently developing a novel time-of-flight PET detector concept that extracts unique timestamps of the early scintillation photons for event timing and positioning. This approach integrates a large-volume scintillation crystal, silicon photomultipliers, and low-noise high-frequency readout electronics. Our recent progress in design optimization and prototype characterization will be presented.
