  - 'The next generation of weak-gravitational-lensing surveys has the potential to
    place stringent constraints on cosmological parameters. However, their analysis
    is limited by systematics such as the intrinsic alignments of galaxies, which
    alter weak-lensing convergence and can lead to biases in cosmological parameter
    estimations. For the first time, in this work, we investigate the impact of intrinsic
    alignments on non-Gaussian statistics of the weak-lensing field using galaxy shapes
    derived from the IllustrisTNG hydrodynamical simulation. We create two catalogs
    of ray-traced convergence maps: one that includes the measured intrinsic shape
    of each galaxy and another where all galaxies are randomly rotated to eliminate
    intrinsic alignments. We compare a range of weak-lensing statistics between the
    two catalogs, including the shear–shear correlation function, the map-level angular
    power spectrum, one-point, peak count, and minimum distribution functions, and
    Minkowski functionals. For each statistic, we assess the level of statistical
    distinguishability between catalogs for a set of future survey angular areas.
    Our results reveal strong small-scale correlation in the alignment of galaxies
    and statistically significant boosts in weak-lensing convergence in both positive
    and negative directions for high-significance peaks and minima, respectively.
    We note that our analysis is at a fixed number density of  ˜ 5 arcmin^-2, drawn
    from a single realization of initial conditions, and does not include observational
    uncertainties or supersample covariance contributions. Weak-lensing analyses utilizing
    non-Gaussian statistics must account for intrinsic alignments to avoid significantly
    compromised cosmological inferences.@eng'
