Astrophysics Events

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...

The Lyman-alpha forest is the primary cosmological tracer in the post-reionization Universe at 2

Abstract: We will start by recalling the weak cosmic censorship conjecture.  Then we will review Christodoulou's construction of naked singularities for the spherically symmetric Einstein-scalar field system. Finally, we will discuss joint work with...

High-precision astrometric data from space observatories, such as the Hubble Space Telescope (HST) and Gaia, are revolutionizing our ability to study the Local Group. 6D phase space measurements (3-dimensional position and velocity) now make it...

Neutron stars are by far the strongest known magnets in the universe. Some of them (called magnetars) generate explosions by suddenly dissipating magnetic energy with a rate up to 10471047 erg/s. These magnetic explosions emit giant gamma-ray flares...
