Star Formation Rate Indicators in Galaxy Formation Simulations José Flores Velazquez, Alex Gurvich, Prof. Faucher-Giguère + FIRE Collaboration
SFR Indicators
H 𝛽 Emissions Assuming Constant SFR : SFR(H 𝜷 ) Indicator traces stars with lifetimes of ~3-10 Myr Finkbeiner et al. 2003
Ultra Violet (UV) Light Assuming Constant SFR : SFR(FUV) Indicator traces stars with lifetimes of ~10-100 Myr JPL-NASA
Figure 1 in (Star)bursts of FIRE… Sparre et al. 2017
My Work
Bursty Non-Bursty
Suggest: Best fit time scale ~4Myr for both the Bursty and Non-Bursty SFRs
Suggest: Best fit time scale ~10Myr for Bursty SFRs and for Non-Bursty SFRs maybe ~20-30 Myr
Future Work • Perform analysis on higher resolution m12i. • Expand our studies to different mass galaxies.
