Title: “Trinity neutrino observatory: progress of the Demonstrator phase” Abstract: In this seminar, I will present the Trinity’s pioneering efforts in Earth-skimming tau neutrino detection. I delve into the evolution of the Trinity project focusing on the Demonstrator phase, detailing its concept, development, and deployment. I will  discuss its operational challenges and highlights the instrument's … Continue reading "CRA Seminar: Mariia Fedkevych (GT)"

Title: Going wider and deeper in the search for gravitational waves Abstract: Gravitational waves (GWs) are oscillations of spacetime itself due to strong dynamical gravity. Since its first detection by the Laser Interferometer Gravitational-wave Observatory (LIGO) in 2015, a network of the ground-based GW detectors detected 90 signals from compact binary mergers by 2020. In … Continue reading "Leo Tsukada -Penn State Un"

Title: Unveiling the TeV Sky in Neutrinos and Gamma rays Abstract: The search for the origin of cosmic rays as well as the signatures of new physics, are closely tied to precision measurements, of both point and diffuse sources of very-high-energy Galactic and extra-galactic emission. The IceCube Neutrino Observatory has been observing a bright, diffuse … Continue reading "Mehr Un Nisa (MSU)"

Title: Insights from Local Simulations of Accretion Disk Coronae: Two-temperature effects, thermal conduction, and radiation transport Abstract: I will present a series of local accretion disk models, i.e., stratified shearing-box magnetohydrodynamic (MHD) simulations, for radiatively efficient accretion flows (REFs), which for the first time, include the effects of field-aligned free-streaming thermal conduction and radiation transport. … Continue reading "CRA Seminar: Chris Bambic Princeton UN"

Title: Challenging the standard accretion disk paradigm with warps, strong magnetic fields and super-Eddington accretion in quasar disks Abstract: "Classical" accretion disks are geometrically thin, radiatively efficient and mechanized by turbulent viscosity. Yet, many observational and theoretical issues challenge this paradigm, especially in quasars. This is perhaps unsurprising, as classical disks do not take into … Continue reading "CRA Seminar: Nick Kaaz – Northwestern UN"
