Extreme Astrophysics with Relativistic Transients

Speaker: Tanmoy Laskar (University of Utah)

Abstract:As the most energetic explosions in the Universe, relativistic astrophysical transients provide a unique opportunity to explore physics at extreme energy scales that are otherwise impossible to investigate in Earth-bound laboratories. I will demonstrate the power of multi-wavelength observations, combined with theoretical modeling, in teasing apart the physics of relativistic extragalactic transients. Shining a special spotlight on radio wavelengths, I will describe how pushing the boundaries of observational efforts is leading to new insights into these extreme events. Using a series of case studies involving gamma-ray bursts, I will describe the multi-messenger revolution currently underway in extragalactic time-domain astrophysics, concluding with highlights of future prospects in this rapidly evolving, data-driven field.

Searching for millicharged particles at the LHC and beyond

Speaker: Matthew Citron (University of California Davis)

Abstract: Arising in hidden sector models of dark matter, millicharged particles could be produced copiously at facilities such as the LHC. However, due to their very small energy depositions, large detectors like CMS or ATLAS are blind to such particles. I will show how sensitivity can instead be achieved through the use of scintillator-based experiments that consist of several layers of long scintillator bars, paired with high-gain, low-noise photomultiplier tubes capable of measuring a single scintillation photon. In this talk I will cover results from two efforts at the LHC: the milliQan experiment, and a prototype for the FORMOSA detector in the forward region. Finally, I will discuss prospects for complementary experiments at high intensity facilities.
