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 […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Matthew J. Temple, Amy L. Rankine, Manda Banerji, Joseph F. Hennawi, Paul C. Hewett | Summary: Understanding the links between different phases of outflows from active galactic nuclei is a key goal in extragalactic astrophysics. Here we compare [OIII] $lambdalambda$4960,5008 outflow signatures in quasars with and without […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Kai-Feng Chen, I-Non Chiu, Masamune Oguri, Yen-Ting Lin, Hironao Miyatake | Summary: We present the first step towards deriving cosmological constraints through the abundances of galaxy clusters selected in a $510,mathrm{deg}^2$ weak-lensing aperture mass map, constructed with the Year-Three shear catalog from the Hyper Suprime-Cam Subaru Strategic […]
Kavli Affiliate: Lindsey Bleem | First 5 Authors: Markus Michael Rau, Florian Kéruzoré, Nesar Ramachandra, 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 […]
