Star Formation Rate Indicators in Galaxy Formation Simulations

José Flores Velazquez, Alex Gurvich,

Prof. Faucher-Giguère

+ FIRE Collaboration

SLIDE 2

SFR Indicators

SLIDE 3

H𝛽 Emissions

Finkbeiner et al. 2003

Assuming Constant SFR: SFR(H𝜷) Indicator traces stars with lifetimes of ~3-10 Myr

SLIDE 4

Ultra Violet (UV) Light

JPL-NASA

Assuming Constant SFR: SFR(FUV) Indicator traces stars with lifetimes of ~10-100 Myr

SLIDE 5

Figure 1 in (Star)bursts of FIRE…Sparre et al. 2017

My Work

Bursty Non-Bursty

SLIDE 8

SLIDE 9

SLIDE 10

Suggest: Best fit time scale ~4Myr for both the Bursty and Non-Bursty SFRs

SLIDE 11

Suggest: Best fit time scale ~10Myr for Bursty SFRs and for Non-Bursty SFRs maybe ~20-30 Myr

SLIDE 12

Future Work

Perform analysis on higher resolution m12i.
Expand our studies to different mass galaxies.
