Cosmological and Astrophysical Parameter Inference from Stacked Galaxy Cluster Profiles Using CAMELS-zoomGZ

Posted by dbos October 14, 2024October 28, 2024Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Elena Hernández-Martínez, Shy Genel, Francisco Villaescusa-Navarro, Ulrich P. Steinwandel, Max E. Lee | Summary: We present a study on the inference of cosmological and astrophysical parameters using stacked galaxy cluster profiles. Utilizing the CAMELS-zoomGZ simulations, we explore how various cluster properties–such as X-ray surface brightness, gas […]

Lens Modeling of STRIDES Strongly Lensed Quasars using Neural Posterior Estimation

Posted by dbos October 14, 2024Stanford

Kavli Affiliate: Aaron Roodman | First 5 Authors: Sydney Erickson, Sebastian Wagner-Carena, Phil Marshall, Martin Millon, Simon Birrer | Summary: Strongly lensed quasars can be used to constrain cosmological parameters through time-delay cosmography. Models of the lens masses are a necessary component of this analysis. To enable time-delay cosmography from a sample of $mathcal{O}(10^3)$ lenses, […]

A relativistic model of b-EMRI systems and their gravitational radiation

Posted by dbos October 13, 2024Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Yucheng Yin, Josh Mathews, Alvin J. K. Chua, Xian Chen, | Summary: A binary extreme-mass-ratio inspiral (b-EMRI) is a hierarchical triple system consisting of a stellar-mass binary black hole (BBH) orbiting a central Kerr supermassive black hole (SMBH). Although predicted by several astrophysical models, b-EMRIs pose a […]

Dubrovin conjecture and the second structure connection

Posted by dbos October 13, 2024Tokyo

Kavli Affiliate: Todor Milanov | First 5 Authors: John Alexander Cruz Morales, Todor Milanov, , , | Summary: We give a reformulation of the Dubrovin conjecture about the semisimplicity of quantum cohomology in terms of the so-called second structure connection of quantum cohomology. The key ingredient in our work is the notion of a twisted […]

Effects of orbital eccentricity on continuous gravitational waveforms from triaxially-deformed precessing neutron stars in tight binaries

Posted by dbos October 12, 2024Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Wen-Fan Feng, Tan Liu, Yan Wang, Lijing Shao, | Summary: The successful detection of continuous gravitational waves (GWs) from spinning neutron stars (NSs) will shape our understanding of the physical properties of dense matter under extreme conditions. Binary population synthesis simulations show that forthcoming space-borne GW detectors […]
