Star cluster formation in the most extreme environments: Insights from the HiPEEC survey

Understand

We present the Hubble imaging Probe of Extreme Environments and Clusters (HiPEEC) survey.

• We fit HST NUV to NIR broadband and H$\alpha$ fluxes, to derive star cluster ages, masses, extinctions and determine the star formation rate (SFR) of 6 merging galaxies.
• These systems are excellent laboratories to trace cluster formation under extreme gas physical conditions, rare in the local universe, but typical for star-forming galaxies at cosmic noon.
• We detect clusters with ages of 1-500 Myr and masses that exceed $10^7$ M$_\odot$.
