The prospect of an ultra-light dark matter particle (also known as Fuzzy Dark Matter, or FDM) has recently drawn attention as a promising alternative to standard Cold Dark Matter (CDM). When the mass of the particle reaches below 10^-21 eV, quantum...

Dynamical tracers of planets, such as their eccentricity, inclination, orbital obliquity, and spin rate, can be used to constrain and refine planet formation and evolution processes. I will begin the talk with mature planetary systems and show how...

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 1: Observations show evidence for the existence of relativistic shock waves in various extreme astrophysical environments, such as gamma-ray bursts and the outflows of binary neutron star mergers. Detailed theoretical models for shock wave...

Astrophysics and several other scientific disciplines currently experience the confluence of three separate developments: large observational programs provide more data than ever; massive simulations probe ever more complex phenomena; and rapid...

Cosmological simulations of galaxy formation have evolved significantly over the last decade. In my talk I will describe recent efforts to model the large-scale distribution of galaxies with cosmological hydrodynamical simulations. After...

Understanding of the role magnetic field in astrophysical environments is essential for many brunches of astrophysical research. The knowledge of magnetic field and polarized radiation that this field induces is important for the ongoing search for...

What regulates star formation and how to explain the Schmidt-Kennicutt relation is a longstanding issue. In this talk, I’ll present simulations of a kiloparsec cube section of a galaxy that show that stellar feedback is sufficient to explain...

Abstract 1: Gravitational evolution induces nonlinearities in the large-scale structure at late times in the Universe. Information that was fully captured by the two-point statistics at the early times gets spread into higher-order statistics...
