Probing the Universe with Fast Radio Bursts
I will highlight recent results leveraging well-localized fast radio bursts (FRBs) to study cosmology and galaxy formation in the z<1 universe. The fundamental signals inherent in FRBs – dispersion measure (DM), rotation measure (RM), and fluence – offer unique constraints on properties of the matter along the sightline to Earth. In turn, we may map out the cosmic web, constrain the density of gas surrounding galaxies, and infer the magnetic fields of the interstellar medium from a diverse population of galaxies. I will describe the standard observational and analysis techniques and conclude by emphasizing areas poised for tremendous growth in the next few years due to the ongoing or upcoming commissioning of new facilities and systems (e.g. CRACO on ASKAP, DSA-110, and the CHIME outriggers project).

What’s new in Scientific Computing for Exascale-Science (Example: LHC)
Multiple large-scale science experiments will enter the Exabyte and Exaflop era in the next years. I will use the CMS experiment at the LHC to flash some improvements and new concepts in scientific computing planned to enable science in the 2030s.
