The Relativistic Spin Precession in the Compact Double Neutron Star System PSR~J1946+2052

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Lingqi Meng, Weiwei Zhu, Michael Kramer, Xueli Miao, Gregory Desvignes | Summary: We observe systematic profile changes in the visible pulsar of the compact double neutron star system PSR~J1946+2052 using observations with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The interpulse of PSR~J1946+2052 changed from single-peak to […]

The Physical Origin of the Mass-Size Relation and Its Scatter of Disk Galaxies

Posted by dbos Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Min Du, Hong-Chuan Ma, Wen-Yu Zhong, Luis C. Ho, Shihong Liao | Summary: Utilizing a kinematic decomposition of simulated galaxies, we focus on galaxies with tiny kinematically inferred stellar halos, indicative of weak external influences. We investigate the intricate interplay between internal (natural) and external (nurture) processes […]

NS5-brane backgrounds and coset CFT partition functions

Posted by dbos Chicago

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Andrea Dei, Emil J. Martinec, , , | Summary: Worldsheet string theory is solvable for a variety of backgrounds involving Neveu-Schwarz fivebranes, in terms of gauged nonlinear sigma models on group manifolds. We compute the worldsheet torus partition function of these models, and propose gauging of […]

Isolated Diffusion: Optimizing Multi-Concept Text-to-Image Generation Training-Freely with Isolated Diffusion Guidance

Posted by dbos Peking

Kavli Affiliate: Jiansheng Chen | First 5 Authors: Jingyuan Zhu, Huimin Ma, Jiansheng Chen, Jian Yuan, | Summary: Large-scale text-to-image diffusion models have achieved great success in synthesizing high-quality and diverse images given target text prompts. Despite the revolutionary image generation ability, current state-of-the-art models still struggle to deal with multi-concept generation accurately in many […]

Modeling the inner part of the jet in M87: Confronting jet morphology with theory

Posted by dbos Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Hai Yang, Feng Yuan, Hui Li, Yosuke Mizuno, Fan Guo | Summary: The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole ("BZ-jet") or the […]

Sample and Communication Efficient Fully Decentralized MARL Policy Evaluation via a New Approach: Local TD update

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Fnu Hairi, Zifan Zhang, Jia Liu, , | Summary: In actor-critic framework for fully decentralized multi-agent reinforcement learning (MARL), one of the key components is the MARL policy evaluation (PE) problem, where a set of $N$ agents work cooperatively to evaluate the value function of the global […]

Runaway Gravitational Production of Dark Photons

Posted by Chicago

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: We demonstrate that gravitational particle production (GPP) of a massive, Abelian, vector (Proca) field during inflation in the presence of nonminimal coupling to gravity may suffer from an instability which leads to runaway production of […]
