Abstract: (arXiv)

To date, only two strongly lensed type Ia supernovae (SNIa) have been discovered with an isolated galaxy acting as the lens: iPTF16geu and SN Zwicky. The observed image fluxes for both lens systems were inconsistent with predictions from a smooth macro lens model. A potential explanation for the anomalous flux ratios is microlensing: additional (de)magnification caused by stars and other compact objects in the lens galaxy. In this work, we combine observations of iPTF16geu and SN Zwicky with simulated microlensing magnification maps, leveraging their standardizable candle properties to constrain the lens galaxy mass slope,

\eta

, and the fraction of dark compact objects,

f_{\rm dc}

. The resulting mass slopes are

\eta = 1.70 \pm 0.07

for iPTF16geu and

\eta = 1.81 \pm 0.10

for SN Zwicky. Our results indicate no evidence for a population of dark compact objects, placing upper limits at the

95\%

confidence level of

f_{\rm dc} < 0.25

for iPTF16geu and

f_{\rm dc} < 0.47

for SN Zwicky. Assuming a constant fraction of dark compact objects for both lensed SNe, we obtain

f_{\rm dc} < 0.19

. These results highlight the potential of strongly lensed SNIa to probe the innermost parts of lens galaxies and learn about compact matter.
