The PASSAGES ($Planck$ All-Sky Survey to Analyze Gravitationally-lensedExtreme Starbursts) collaboration has recently defined a sample of 30gravitationally-lensed dusty star-forming galaxies (DSFGs). These rare,submillimeter-selected objects enable high-resolution views of the most extremesites of star formation in galaxies at Cosmic Noon. Here, we present the firstmajor compilation of strong lensing analyses using LENSTOOL for PASSAGES,including 15 objects spanning $z=1.1-3.3$, using complementary information from$0.6^{\prime\prime}$-resolution 1 mm Atacama Large Millimeter/submillimeterArray (ALMA) and $0.4^{\prime\prime}$ 5 cm Jansky Very Large Array continuumimaging, in tandem with 1.6$\mu$m $Hubble$ and optical imaging with Gemini-S.Magnifications range from $\mu = 2 - 28$ (median $\mu=7$), yielding intrinsicinfrared luminosities of $L_{\rm IR} = 0.2 - 5.9 \times 10^{13}~L_\odot$(median ${1.4}\times 10^{13}~L_\odot$) and inferred star formation rates of$170-6300~M_\odot~{\rm yr}^{-1}$ (median $1500~M_\odot~{\rm yr}^{-1}$). Theseresults suggest that the PASSAGES objects comprise some of the most extremeknown starbursts, rivaling the luminosities of even the brightest unlensedobjects, further amplified by lensing. The intrinsic sizes of far-infraredcontinuum regions are large ($R_{\rm e} = {1.7 - 4.3}$ kpc; median $3.0$ kpc)but consistent with $L_{\rm IR}-R_{\rm e}$ scaling relations for $z>1$ DSFGs,suggesting a widespread spatial distribution of star formation. Withmodestly-high angular resolution, we explore if these objects might be maximalstarbursts. Instead of approaching Eddington-limited surface densities, abovewhich radiation pressure will disrupt further star formation, they are safelysub-Eddington -- at least on global, galaxy-integrated scales.
