PCAC-GAN: A Sparse-Tensor-Based Generative Adversarial Network for 3D Point Cloud Attribute Compression

Kavli Affiliate: Wei Gao | First 5 Authors: Xiaolong Mao, Hui Yuan, Xin Lu, Raouf Hamzaoui, Wei Gao | Summary: Learning-based methods have proven successful in compressing geometric information for point clouds. For attribute compression, however, they still lag behind non-learning-based methods such as the MPEG G-PCC standard. To bridge this gap, we propose a […]

Constraints on blue and red tilted primordial power spectra using dwarf galaxy properties

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Ariane Dekker, Andrey Kravtsov, , , | Summary: Although the standard $Lambda$+Cold Dark Matter ($Lambda$CDM) model is well tested on large scales, the primordial power spectrum may deviate from the $Lambda$CDM spectrum on small scales due to specific dark matter properties or alternative inflationary models. These deviations […]

Local Description of Decoherence of Quantum Superpositions by Black Holes and Other Bodies

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: It was previously shown that if an experimenter, Alice, puts a massive or charged body in a quantum spatial superposition, then the presence of a black hole (or more generally any Killing horizon) will eventually […]

Turbulent Diffuse Molecular Media with Non-ideal Magnetohydrodynamics and Consistent Thermochemistry: Numerical Simulations and Dynamic Characteristics

Kavli Affiliate: Lile Wang | First 5 Authors: Nannan Yue, Lile Wang, Thomas Bisbas, Donghui Quan, Di Li | Summary: Turbulent diffuse molecular clouds can exhibit complicated morphologies caused by the interactions among radiation, chemistry, fluids, and fields. We performed full 3D simulations for turbulent diffuse molecular interstellar media, featuring time-dependent non-equilibrium thermochemistry co-evolved with […]

Exploring the Core-galaxy Connection

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Isabele Souza Vitório, Michael Buehlmann, Eve Kovacs, Patricia Larsen, Nicholas Frontiere | Summary: Halo core tracking is a novel concept designed to efficiently follow halo substructure in large simulations. We have recently developed this concept in gravity-only simulations to investigate the galaxy-halo connection in the context of […]
