| 4 | | We are measuring rate coefficients of the reaction H^^-^^ + H = H,,2,,. This is an important mechanism for forming H,,2,, molecules which act as a coolant in primordial clouds. This cooling effect is necessary in the formation of the first stars. Knowing these rates would allow us to accurately model the formation of the first stars and see if protogalactic halos cooled down before they would have likely collided with another halo.[[br]][[br]][[Image(https://docs.astro.columbia.edu/attachment/wiki/SavinGroup/MergedBeams/First Star 2.png?format=raw, 50%)]]` Abel et al, Science 2002` |
