    Update on Neutron Star Smash-Up: Jet Hits a Roadblock

    New radio observations provide additional evidence supporting the "cocoon model" for the neutron star merger GW170817 that took place on Aug 17. The model, originally proposed by the GROWTH team explains the electromagnetic data for GW170817 captured by many telescopes around the world across multiple wavelengths.

Global Relay of Observatories Watching Transients Happen (GROWTH) is a 5 year project, funded by the National Science Foundation to advance our understanding of cosmic transient events - supernovae, white dwarf detonations, merging neutron stars, fast moving near-earth asteroids, gamma-ray bursts and more. Led by Caltech, GROWTH partner institutions from around the world have created a network of telescopes to continuously observe the transient sky unbeaten by sunrise. Such extended observations in the first 24 hours after a cosmic transient is detected help us to localize the primary sources of gravitational waves, identify the long sought cosmic location of heavy element production (see Caltech-led LIGO and astronomy teams strike gold) , track and analyze small near-earth asteroids and much more.


Next to developing data-driven educational modules for university courses in astronomy, GROWTH provides multiple opportunities for training and professional development to students and young researchers in astronomy, astrophysics and closely related fields in physical sciences.
