Constraining cosmology with weak lensing voids

Understand

Upcoming surveys such as \LSST{} and \Euclid{} will significantly improve the power of weak lensing as a cosmological probe.

• To maximise the information that can be extracted from these surveys, it is important to explore novel statistics that complement standard weak lensing statistics such as the shear-shear correlation function and peak counts.
• In this work, we use a recently proposed weak lensing observable -- weak lensing voids -- to make parameter constraint forecasts for an LSST-like survey.
• We use the \cosmoslics{} $w$CDM simulation suite to measure void statistics as a function of cosmological parameters.
