Intracluster light is thought to originate from stars that were ripped away from their parent galaxies by gravitational tides and galaxy interactions during the build up of the cluster. The stars from such interactions will accumulate over time, so...

Plasmas throughout the Universe are filled with complex, highly nonlinear turbulent fluctuations that transfer energy from the large driving scales down to the smallest scales where energy can be most efficiently dissipated. In the absence of...

Abstract: Black hole X-ray binaries and Active Galactic Nuclei transition through a series of accretion states in a well-defined order. During a state transition, the accretion flow changes from a hot geometrically thick accretion flow, emitting a...

Transit timing variations (TTVs) are ubiquitous in exoplanet transit datasets, with Kepler alone containing ~2,000 periodic TTVs. However, these TTVs are often ambiguous from a model selection perspective, as it is difficult to determine the...

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Abstract: Earthquakes exhibit complex behavior at all scales, from the evolution of slip during a single rupture lasting seconds to minutes, to the statistics of regional seismicity over years or centuries. The origin of complexity in fault behavior...

Results from JWST have challenged our prior views of galaxy formation and supermassive black hole growth at the earliest cosmic epochs. Our knowledge of the distant universe has evolved rapidly over the last two years of science operations, and...

Abstract: A clear outcome of Snowmass 2021 and now the US P5 report was the community support for R&D towards a future muon collider. In this talk we will discuss the general physics program that becomes available to the community during the...
