Field-level simulation-based inference with galaxy catalogs: the impact of systematic effects

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Natalí S. M. de Santi, Francisco Villaescusa-Navarro, L. Raul Abramo, Helen Shao, Lucia A. Perez | Summary: It has been recently shown that a powerful way to constrain cosmological parameters from galaxy redshift surveys is to train graph neural networks to perform field-level likelihood-free inference without imposing […]

Separated twins or just siblings? A multi-planet system around an M dwarf including a cool sub-Neptune

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Mallory Harris, Diana Dragomir, Ismael Mireles, Karen A. Collins, Solène Ulmer-Moll | Summary: We report the discovery of two TESS sub-Neptunes orbiting the early M dwarf TOI-904 (TIC 261257684). Both exoplanets, TOI-904 b and c, were initially observed in TESS sector 12 with twin sizes of 2.49R$_oplus$ […]

Atmospheric carbon depletion as a tracer of water oceans and biomass on temperate terrestrial exoplanets

Kavli Affiliate: Sara Seager | First 5 Authors: Amaury H. M. J. Triaud, Julien de Wit, Frieder Klein, Martin Turbet, Benjamin V. Rackham | Summary: The conventional observables to identify a habitable or inhabited environment in exoplanets, such as an ocean glint or abundant atmospheric O$_2$, will be challenging to detect with present or upcoming […]

Quantum Hamiltonian Algorithms for Maximum Independent Sets

Kavli Affiliate: Frank Wilczek | First 5 Authors: Xianjue Zhao, Peiyun Ge, Hongye Yu, Li You, Frank Wilczek | Summary: We compare two quantum Hamiltonian algorithms that address the maximum independent set problem: one based on emergent non-abelian gauge matrix in adiabatic evolution of an energetically isolated manifold of states; and one based on designed […]
