Title: Particle spectra and HBT radii for simulated central nuclear collisions of C + C, Al + Al, Cu + Cu, Au + Au, and Pb + Pb from $$\sqrt{s}$$ = 62.4-2760  GeV

Here, we study the temperature profile, pion spectra, and HBT radii in central, symmetric, and boost-invariant nuclear collisions, using a super hybrid model for heavy-ion collisions (SONIC), combining pre-equilibrium flow with viscous hydrodynamics and late-stage hadronic rescatterings. In particular, we simulate Pb + Pb collisions at $$\sqrt{s}$$ = 2.76 TeV, Au + Au, Cu + Cu, Al + Al, and C + C collisions at $$\sqrt{s}$$ = 200 GeV, and Au + Au and Cu + Cu collisions at $$\sqrt{s}$$ = 62.4 GeV. We find that SONIC provides a good match to the pion spectra and HBT radii for all collision systems and energies, confirming earlier work that a combination of pre-equilibrium flow, viscosity, and QCD equation of state can resolve the so-called HBT puzzle. For reference, we also show p + p collisions at $$\sqrt{s}$$ = 7 TeV. We make tabulated data for the 2 + 1 dimensional temperature evolution of all systems publicly available for the use in future jet energy loss or similar studies.
