The Kavli Institute for Particle Astrophysics and Cosmology, or KIPAC, was inaugurated in 2003 as an independent laboratory of Stanford University to serve as a bridge between the disciplines of astrophysics, cosmology and particle physics. KIPAC's members work in the Physics and Applied Physics Departments on the Stanford campus and at the SLAC National Accelerator Laboratory. Its mission is to bring the resources of modern computational, experimental, observational and theoretical science to bear on our understanding of the universe at large.


Research Highlights

Oct 1, 2020 | Delving Back Deeper: Towards GRBs as Standard Candles

Standard candles are objects with fixed luminosities that can be calculated by taking advantage of well-established relationships between an object’s luminosity and its physical properties—relationships that are independent of the object’s distance. Such objects enable the calculation of accurate astronomical distances. The furthest well-established standard candles to date are Type Ia supernovae, but GRBs have been observed at much greater distances (up to 13.2 billion light years vs. 11 billion light years for Type Ia supernovae). Thus, GRBs could provide accurate distances to events that happened only a few hundred millions years after the Big Bang, very close to when stars began to form in the Universe.
