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 … 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"
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"
Title: Planets are not Points: Structure Evolution and Dynamical Evolution are Intertwined Abstract: The two subfields of planetary structure evolution and planetary dynamics are two rich and complex fields that have advanced in lockstep, but independently of one another. I will discuss how accounting for minor interior structure evolution of a planet can have a … Continue reading "CRA Seminar: Tiger Lu – Yale UN"
Title: JWST's Little Red Dots: Masters of Disguise in the High-Redshift Universe This talk will explore the exciting journey to probe several populations of black holes, spanning from the distant to the local Universe. I will focus primarily on the "little red dots" (LRDs), a newly discovered and puzzling population of compact red sources at … Continue reading "CRA Seminar: Fabio Pacucci – Harvard cfa"
Title: Gravitational waves: from black holes to the cosmos Gravitational waves reveal the universe through an entirely unique spectrum, complementary to electromagnetic and neutrino observations. Although the field is young, it has already revolutionized our understanding of black holes and neutron stars, with implications for gravity, stellar and galactic astrophysics, nuclear physics and cosmology. In … Continue reading "CRA Seminar – Maximiliano Isi – Flatiron Inst. NYC"
