Kavli Affiliate: Vincent Ferrera | Authors: Fabian A Munoz Silva, Greg Jensen, Maxwell Shinn, Yelda Alkan, John Murray, Herbert Terrace and Vincent P Ferrera | Summary: Transitive inference (TI) is a cognitive process in which decisions are guided by internal representations of abstract relationships. While the mechanisms underlying transitive learning have been well studied, the […]
Kavli Affiliate: Avi Shporer | Summary:We present the discovery and validation of TOI-7166b, a 2.01+/-0.05R_Earth planet orbiting a nearby low-mass star. We validated the planet by combining TESS and multi-color high-precision photometric observations from ground-based telescopes, together with spectroscopic data, high-contrast imaging, archival images, and statistical arguments. The host star is an M4-type dwarf at […]
Kavli Affiliate: Avi Shporer | Summary:For small planets orbiting within the habitable zones of their host stars, multicolour validation via photometric transit observations offers an efficient alternative to prioritize targets before intensive radial-velocity follow-up, thereby expanding the sample of habitable-zone exoplanets amenable for atmospheric characterisation. In this study, we validate two exceptional habitable-zone TESS candidates, […]

Kavli Affiliate: Eli Rykoff | Summary:We show that, in flat $Λ$CDM, low-redshift structure probes — cluster abundances, 3$times$2-point analyses, and full-shape clustering — are mutually consistent, jointly delivering precise constraints on $σ_8$ and $Ω_rm m$ that agree with geometrical datasets (CMB+BAO+SN). In $w_0w_a$CDM, adding clusters to the geometry dataset reduces the evidence for evolving dark […]
