Challenges to the Lambda CDM Cosmology

Kavli Affiliate: George Efstathiou | Summary:Observations of the cosmic microwave backgroundradiation are described to remarkable accuracy by the six-parameterLambda CDM cosmology. However, the key ingredients of this model, namely dark matter, dark energy and cosmic inflation are not understood at a fundamental level. It is therefore important to investigate tensions between the CMB and other […]

An IXPE-Led X-ray Spectro-Polarimetric Campaign on the Soft State of Cygnus X-1: X-ray Polarimetric Evidence for Strong Gravitational Lensing

Kavli Affiliate: Herman L. Marshall | First 5 Authors: James F. Steiner, Edward Nathan, Kun Hu, Henric Krawczynski, Michal Dovciak | Summary: We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwavelength data during the campaign are likewise […]

Weak-Lensing Shear-Selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: I. Cluster Catalog, Selection Function and Mass–Observable Relation

Kavli Affiliate: Masahiro Takada | Summary:We present the first step toward deriving cosmological constraints through the abundances of galaxy clusters selected in a $510,mathrmdeg^2$ weak-lensing aperture mass map, constructed with the Year-Three shear catalog from the Hyper Suprime-Cam Subaru Strategic Program. We adopt a conservative source galaxy selection to construct a sample of $129$ weak-lensing […]

Reducing Model Error Using Optimised Galaxy Selection: Weak Lensing Cluster Mass Estimation

Kavli Affiliate: Lindsey Bleem | Summary:Galaxy clusters are one of the most powerful probes to study extensions of General Relativity and the Standard Cosmological Model. Upcoming surveys like the Vera Rubin Observatory’s Legacy Survey of Space and Time are expected to revolutionise the field, by enabling the analysis of cluster samples of unprecedented size and […]

Low-dimensional olfactory signatures of fruit ripening and fermentation

Kavli Affiliate: Tatyana Sharpee | Authors: Yuansheng Zhou, Thomas F O’Connell, Majid Ghaninia, Brian Smith, Elizabeth J Hong and Tatyana O Sharpee | Summary: Odors provide an important communication channel between plants and animals. Fruits, vital nutrient sources for animals, emit a complex array of monomolecular volatiles. Animals can use the structure of these mixtures […]

Posterior parietal cortex maps progress along routes sharing the same meta-structure

Kavli Affiliate: Douglas Nitz | Authors: Alexander B Johnson and Douglas A Nitz | Summary: Neurons of posterior parietal cortex were recorded as rats performed a working memory task within a network of intersecting paths. The specific routes utilized in task performance provided opportunity to contrast responses of posterior parietal cortex sub-populations to linear and […]
