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 … 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 … 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 … 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"

Title: Gravitational Wave and Electromagnetic Signals Associated With the Tidal Disruption of White Dwarfs Abstract: I will discuss the gravitational-wave and electromagnetic signals expected to accompany the tidal disruption of a white dwarf by a massive (i.e., “intermediate mass” black hole). Since white dwarfs are very compact, they can only be disrupted outside of the … Continue reading "Special CRA Seminar Michael Eracleous – Penn State 11am-12 noon"
