Statistical imprints of wave-like dark matter on multiply-imaged galaxies in strong cluster lenses from JWST
Nino Ephremidze, Daniel Gilman, Cora Dvorkin
Wave-like dark matter (DM) is an elusive dark matter (DM) candidate. The model, often also called fuzzy or ultralight DM, proposes that DM is an extremely light ($m\sim10^{-22}…
Robustness of Neural Networks for CMB Polarization Foreground Removal
Luca Gomez Bachar, Cora Dvorkin, Alberto Daniel Supanitsky
The detection of Cosmic Microwave Background primordial -mode polarization would constitute a ``smoking gun" signal of primordial gravitational waves. However, this measurement…
The Future of Artificial Intelligence and the Mathematical and Physical Sciences (AI+MPS)
Andrew Ferguson, Marisa LaFleur, Lars Ruthotto +97
This community paper developed out of the NSF Workshop on the Future of Artificial Intelligence (AI) and the Mathematical and Physics Sciences (MPS), which was held in March 2025 w…
Fast Fourier Transform evaluation of the Fresnel integral for gravitational-wave lensing
Nino Ephremidze, Marc Kamionkowski, Cora Dvorkin
Gravitational waves (GWs) exhibit wave-optics effects when their wavelength is comparable to the scale of the gravitational lens. This may occur in lensing from galactic subhalos i…
Constraining Power of Wavelet vs. Power Spectrum Statistics for CMB Lensing and Weak Lensing with Learned Binning
Kyle Boone, Georgios Valogiannis, Marco Gatti +1
We present forecasts for constraints on the matter density () and the amplitude of matter density fluctuations at 8hMpc () from CMB lensing convergence maps and…
Astrophysical Tests of Dark Matter Self-Interactions
Susmita Adhikari, Arka Banerjee, Kimberly K. Boddy +11
Self-interacting dark matter (SIDM) arises generically in scenarios for physics beyond the Standard Model that have dark sectors with light mediators or strong dynamics. The self-i…
