Kavli Affiliate: Lina Necib | First 5 Authors: Arpit Arora, Robyn E. Sanderson, Sukanya Chakrabarti, Andrew Wetzel, Thomas Donlon II | Summary: Measurements of the accelerations of stars enabled by time-series extreme-precision spectroscopic observations, from pulsar timing, and from eclipsing binary stars in the Solar Neighborhood offer insights into the mass distribution of the Milky […]
Kavli Affiliate: Anthony Lasenby | First 5 Authors: Will Barker, Michael Hobson, Anthony Lasenby, Yun-Cherng Lin, Zhiyuan Wei | Summary: The Poincar’e gauge theory (PGT) of gravity provides a viable formulation of general relativity (Einstein-Cartan theory), and a popular model-building framework for modified gravity with torsion. Notoriously, however, the PGT terms which propagate vector torsion […]

Kavli Affiliate: George Efstathiou | First 5 Authors: 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 […]

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 […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Nimisha Kumari, Renske Smit, Joris Witstok, Marco Sirianni, Roberto Maiolino | Summary: We investigate the physical properties of Lyman-alpha emitters (LAEs) and non-Lyman-alpha emitters (non-LAEs) at z$sim$4.8–9.6 via a stacking analysis of 253 JWST/NIRSpec spectra of galaxies observed as part of the JWST Advanced Deep Extragalactic Survey […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: I-Non Chiu, Kai-Feng Chen, Masamune Oguri, Markus M. Rau, Hironao Miyatake | Summary: We present cosmological constraints using the abundance of weak-lensing shear-selected galaxy clusters in the Hyper Suprime-Cam (HSC) Subaru Strategic Program. The clusters are selected on the mass maps constructed using the three-year (Y3) weak-lensing […]
