Text-to-3D using Gaussian Splatting

Kavli Affiliate: Feng Wang | First 5 Authors: Zilong Chen, Feng Wang, Huaping Liu, , | Summary: In this paper, we present Gaussian Splatting based text-to-3D generation (GSGEN), a novel approach for generating high-quality 3D objects. Previous methods suffer from inaccurate geometry and limited fidelity due to the absence of 3D prior and proper representation. […]

Statistics of thermal gas pressure as a probe of cosmology and galaxy formation

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Ziyang Chen, Drew Jamieson, Eiichiro Komatsu, Sownak Bose, Klaus Dolag | Summary: The statistics of thermal gas pressure are a new and promising probe of cosmology and astrophysics. The large-scale cross-correlation between galaxies and the thermal Sunyaev-Zeldovich effect gives the bias-weighted mean electron pressure, $langle b_mathrm{h}P_erangle$. In […]
