The discovery of the Higgs boson by the ATLAS and CMS experiments at CERN’s Large Hadron Collider (LHC) marks a breakthrough in particle physics, and it stands with the greatest scientific discoveries of all time. The Higgs boson is a ripple of a...

Precision observations of the cosmos have established the concordance model of cosmology, but deep questions remain about the origin of cosmic structure and the fundamental nature of the dark sector. Further, significant discrepancies have arisen in...

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...

Magnetic reconnection is a fundamental plasma process whereby two merging flows with oppositely oriented magnetic fields drive the reconfiguration of the field topology inside a current sheet, which rapidly converts magnetic into kinetic energy...

Abstract: Complementing the spectacular breakthroughs in gravitational wave and multi-messenger observations of merging black holes and neutron stars, advancements in our theoretical understanding and modelling of strong gravity are essential to...

Star formation in galaxies are governed by the complex interplay of several nonlinear physical mechanisms operating in the interstellar medium (ISM). However, in spite of the underlying complexity, there is overwhelming evidence for fundamental...

Star-shredding supermassive black holes (Tidal Disruption Events, TDEs) are potential emitters of high energy hadrons and neutrinos. Several TDEs have been observed as coincident with neutrino events detected at the IceCube neutrino observatory. I...
