Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Yue Pan, Christine M. Simpson, Andrey Kravtsov, Facundo A. Gómez, Robert J. J. Grand | Summary: We compare here the colours of simulated satellite galaxies from the Auriga project to observed satellite galaxies from the Exploration of Local VolumE Satellites (ELVES) Survey of satellite galaxies around local […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Huanqing Chen, Rupert Croft, Nickolay Y. Gnedin, , | Summary: High-redshift quasars ionize HeII into HeIII around them, heating the IGM in the process and creating large regions with elevated temperature. In this work, we demonstrate a method based on a convolutional neural network (CNN) to […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Erik J. Gustafson, Henry Lamm, Ying-Ying Li, Wanqiang Liu | Summary: The advantage of simulating lattice field theory with quantum computers is hamstrung by the limited resources that induce large errors from finite volume and sizable lattice spacings. Previous work has shown how classical simulations […]
Kavli Affiliate: Wendy Freedman | First 5 Authors: Giacomo Beccari, Henri M. J. Boffin, Paola Andreani, Selma de Mink, Wendy Freedman | Summary: Being one of the most fascinating and ancient sciences, astronomy has always played a special role in society. In 2022 ESO organised an online conference to offer the community a platform to […]
Kavli Affiliate: Brian Nord | First 5 Authors: Thomas Y. Chen, Biprateep Dey, Aishik Ghosh, Michael Kagan, Brian Nord | Summary: Estimating uncertainty is at the core of performing scientific measurements in HEP: a measurement is not useful without an estimate of its uncertainty. The goal of uncertainty quantification (UQ) is inextricably linked to the […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Clarke J. Esmerian, Nickolay Y. Gnedin, , , | Summary: We introduce a model for the explicit evolution of interstellar dust in a cosmological galaxy formation simulation. We post-process a simulation from the Cosmic Reionization on Computers project (CROC, Gnedin 2014), integrating an ordinary differential equation […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Jonathan J. Heckman, Austin Joyce, Jeremy Sakstein, Mark Trodden, | Summary: We explore potential uses of physics formulated in Kleinian (i.e., $2+2$) signature spacetimes as a tool for understanding properties of physics in Lorentzian (i.e., $3+1$) signature. Much as Euclidean (i.e., $4+0$) signature quantities can be used […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Nickolay Y. Gnedin, Piero Madau, , , | Summary: The transformation of cold neutral intergalactic hydrogen into a highly ionized warm plasma marks the end of the cosmic dark ages and the beginning of the age of galaxies. The details of this process reflect the nature […]

Kavli Affiliate: Brian Nord | First 5 Authors: Moonzarin Reza, Yuanyuan Zhang, Brian Nord, Jason Poh, Aleksandra Ciprijanovic | Summary: Inferring the values and uncertainties of cosmological parameters in a cosmology model is of paramount importance for modern cosmic observations. In this paper, we use the simulation-based inference (SBI) approach to estimate cosmological constraints from […]
