A Ground-Based Transit Observation of the Long-Period Extremely Low-Density Planet HIP 41378 f

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Juliana García-Mejía, Juliana García-Mejía, , , | Summary: We present a ground-based transit detection of HIP 41378 f, a long-period ($P = 542$ days), extremely low-density ($0.09 pm 0.02$ g cm$^-3$) giant exoplanet in a dynamically complex system. Using photometry from Tierras, TRAPPIST-North, and multiple LCOGT sites, […]

Planck Constraints on Axion-Like Particles through Isotropic Cosmic Birefringence

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Toshiya Namikawa, , , | Summary: We present constraints on isotropic cosmic birefringence induced by axion-like particles (ALPs), derived from the analysis of cosmic microwave background (CMB) polarization measurements obtained with the high-frequency channels of Planck. Recent measurements report a hint of isotropic cosmic birefringence, […]

The Singapore Consensus on Global AI Safety Research Priorities

Kavli Affiliate: Max Tegmark | First 5 Authors: Yoshua Bengio, Yoshua Bengio, , , | Summary: Rapidly improving AI capabilities and autonomy hold significant promise of transformation, but are also driving vigorous debate on how to ensure that AI is safe, i.e., trustworthy, reliable, and secure. Building a trusted ecosystem is therefore essential — it […]

An iterative CMB lensing estimator minimizing instrumental noise bias

Kavli Affiliate: Anthony Challinor | First 5 Authors: Louis Legrand, Louis Legrand, , , | Summary: Noise maps from CMB experiments are generally statistically anisotropic, due to scanning strategies, atmospheric conditions, or instrumental effects. Any mis-modeling of this complex noise can bias the reconstruction of the lensing potential and the measurement of the lensing power […]
