COOL-LAMPS. VII. Quantifying Strong-lens Scaling Relations with 177 Cluster-scale Gravitational Lenses in DECaLS

Posted by January 16, 2024Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Simon D. Mork, Michael D. Gladders, Gourav Khullar, Keren Sharon, Nathalie Chicoine | Summary: We compute parametric measurements of the Einstein-radius-enclosed total mass for 177 cluster-scale strong gravitational lenses identified by the ChicagO Optically-selected Lenses Located At the Margins of Public Surveys (COOL-LAMPS) collaboration with lens […]

Stochastic Inflation in General Relativity

Posted by dbos January 16, 2024Cambridge

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Yoann L. Launay, Gerasimos I. Rigopoulos, E. P. S. Shellard, , | Summary: We provide a formulation of Stochastic Inflation in full general relativity that goes beyond the slow-roll and separate universe approximations. We show how gauge invariant Langevin source terms can be obtained for […]

Schrödinger cats growing up to 60 qubits and dancing in a cat scar enforced discrete time crystal

Posted by dbos January 16, 2024Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Zehang Bao, Shibo Xu, Zixuan Song, Ke Wang, Liang Xiang | Summary: Greenberger-Horne-Zeilinger (GHZ) states, as maximally entangled Schr"{o}dinger cat states, play vital roles in the foundations of quantum physics and technology, but creating and preserving these fragile states pose tremendous challenges. Discrete time crystals (DTCs), originally […]

Transferring Core Knowledge via Learngenes

Posted by dbos January 16, 2024Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Fu Feng, Jing Wang, Xin Geng, , | Summary: The pre-training paradigm fine-tunes the models trained on large-scale datasets to downstream tasks with enhanced performance. It transfers all knowledge to downstream tasks without discriminating which part is necessary or unnecessary, which may lead to negative transfer. In […]

Dynamic instability analysis for bumblebee black holes: the odd parity

Posted by dbos January 15, 2024Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Zhan-Feng Mai, Rui Xu, Dicong Liang, Lijing Shao, | Summary: Spherical black-hole (BH) solutions have been found in the bumblebee gravity where a vector field nonminimally couples to the Ricci tensor. We study dynamic (in)stability associated with the gravitational and vector perturbations of odd parity against these […]

Probing Primordial Black Hole Scenarios with Terrestrial Gravitational Wave Detectors

Posted by dbos January 15, 2024Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Misao Sasaki, , , | Summary: It is possible that primordial black holes consitute (or consituted) a significant fraction of the energy budget of our universe. Terrestrial gravitational wave detectors offer the opportunity to test the existence of primordial black holes in two different mass […]
