Web: https://icecube.wisc.edu/~akheirandish/ Title: Cosmic Neutrinos and the Unique Insights They Provide into the High-Energy Universe Abstract: The era of high-energy astrophysics with cosmic neutrinos began with the discovery of high-energy neutrinos with extraterrestrial origin in IceCube. The observation of high-energy cosmic neutrino flux revealed the prominent and larger than expected role of hadronic interactions in … Continue reading "CRA Seminar by Dr. Ali Kheirandish (University of Wisconsin)"

Web: https://www.ics.uzh.ch/~pcapelo/index.html Title: Dual active galactic nuclei and the pairing of supermassive black holes in the LISA era Abstract: Pairs of accreting supermassive black holes (SMBHs), known as dual active galactic nuclei (AGN), and the generation of gravitational waves (GWs) from the inspiral and coalescence of SMBHs are two faces of the same coin. The … Continue reading "CRA Seminar by Dr. Pedro Capelo (University of Zurich)"

Trinity: An air shower imaging instrument to detect ultrahigh-energy neutrinos The detection of neutrinos with IceCube has cracked open a new window in astrophysics at the TeV-PeV energy scale. The revelation of a relatively hard neutrino spectrum and the unknown origin of the flux are two motivations to extend neutrino measurements to even higher energies, … Continue reading "CRA Seminar by Prof. Nepomuk Otte (Georgia Tech)"

Web: https://physics.ua.edu/profiles/preethi-nair/ Title: Constraining the Demographics of Accreting Supermassive Black Holes and their Role in Galaxy Quenching in the nearby Universe Understanding the mechanisms which trigger an Active Galactic Nuclei (AGN or accreting supermassive black hole) and the role of these AGN in galaxy evolution, specifically in regulating or quenching star formation in galaxies, is … Continue reading "CRA Seminar by Prof. Preethi Nair (University of Alabama)"

The discovery of numerous small exoplanets has brought the search for life beyond the Solar System into sharp focus on many potentially habitable worlds where life may exist. However, many factors and processes can affect planetary climate and habitability, most of which are currently unconstrained by observations, and their effects must be understood to accurately … Continue reading "School of Physics Colloquium: Aomawa L.
