Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Optical, and X-ray (ICM-SHOX). Paper II: Galaxy cluster sample overview

Posted by April 5, 2024Caltech

Kavli Affiliate: Sunil Golwala | First 5 Authors: Emily M. Silich, Elena Bellomi, Jack Sayers, John ZuHone, Urmila Chadayammuri | Summary: Galaxy cluster mergers are representative of a wide range of physics, making them an excellent probe of the properties of dark matter and the ionized plasma of the intracluster medium. To date, most studies […]

Unified laser stabilization and isolation on a silicon chip

Posted by April 3, 2024UCSB

Kavli Affiliate: John E. Bowers | First 5 Authors: Alexander D. White, Geun Ho Ahn, Kasper Van Gasse, Richard Luhtaru, Joel Guo | Summary: Rapid progress in photonics has led to an explosion of integrated devices that promise to deliver the same performance as table-top technology at the nanoscale; heralding the next generation of optical […]

No need to know: astrophysics-free gravitational-wave cosmology

Posted by April 2, 2024Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Thomas A. Callister, Jose María Ezquiaga, Michael Zevin, Daniel E. Holz | Summary: Gravitational waves from merging compact objects encode direct information about the luminosity distance to the binary. When paired with a redshift measurement, this enables standard-siren cosmology: a Hubble diagram can […]

Mass calibration of DES Year-3 clusters via SPT-3G CMB cluster lensing

Posted by April 2, 2024Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: B. Ansarinejad, S. Raghunathan, T. M. C. Abbott, P. A. R. Ade, M. Aguena | Summary: We measure the stacked lensing signal in the direction of galaxy clusters in the Dark Energy Survey Year 3 (DES Y3) redMaPPer sample, using cosmic microwave background (CMB) temperature data from […]

Quantifying the uncertainty in the time-redshift relationship

Posted by March 28, 2024Chicago

Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, , , , | Summary: The age of the Universe at a given redshift is a fundamental relationship in cosmology. For many years, the uncertainties in it were dauntingly large, close to a factor of 2. In this age of precision cosmology, they […]

Bringing Textual Prompt to AI-Generated Image Quality Assessment

Posted by March 27, 2024Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Bowen Qu, Haohui Li, Wei Gao, , | Summary: AI-Generated Images (AGIs) have inherent multimodal nature. Unlike traditional image quality assessment (IQA) on natural scenarios, AGIs quality assessment (AGIQA) takes the correspondence of image and its textual prompt into consideration. This is coupled in the ground truth […]

Testing the $mathbfΛ$CDM Cosmological Model with Forthcoming Measurements of the Cosmic Microwave Background with SPT-3G

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: K. Prabhu, S. Raghunathan, M. Millea, G. Lynch, P. A. R. Ade | Summary: We forecast constraints on cosmological parameters enabled by three surveys conducted with SPT-3G, the third-generation camera on the South Pole Telescope. The surveys cover separate regions of 1500, 2650, and 6000 ${rm deg}^{2}$ […]
