Kavli Affiliate: Brian Nord | First 5 Authors: Luisa Lucie-Smith, Hiranya V. Peiris, Andrew Pontzen, Brian Nord, Jeyan Thiyagalingam | Summary: The density profiles of dark matter halos are typically modeled using empirical formulae fitted to the density profiles of relaxed halo populations. We present a neural network model that is trained to learn the […]

Kavli Affiliate: Salman Habib | First 5 Authors: Aurora Cossairt, Michael Buehlmann, Eve Kovacs, Xin Liu, Salman Habib | Summary: We present a detailed study of fossil group candidates identified in "Last Journey", a gravity-only cosmological simulation covering a $(3.4, h^{-1}mathrm{Gpc})^3$ volume with a particle mass resolution of $m_p approx 2.7 times 10^9, h^{-1}mathrm{M}_odot$. The […]

Kavli Affiliate: Brian Nord | First 5 Authors: Fengxue Zhang, Brian Nord, Yuxin Chen, , | Summary: Bayesian optimization has been challenged by datasets with large-scale, high-dimensional, and non-stationary characteristics, which are common in real-world scenarios. Recent works attempt to handle such input by applying neural networks ahead of the classical Gaussian process to learn […]
Kavli Affiliate: Salman Habib | First 5 Authors: Meghna Bhattacharya, Paolo Calafiura, Taylor Childers, Mark Dewing, Zhihua Dong | Summary: Today’s world of scientific software for High Energy Physics (HEP) is powered by x86 code, while the future will be much more reliant on accelerators like GPUs and FPGAs. The portable parallelization strategies (PPS) project […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Jonathan Kozaczuk, Zhen Liu, Tong Ou, Michael J. Ramsey-Musolf | Summary: An essential goal of the Higgs physics program at the LHC and beyond is to explore the nature of the Higgs potential and shed light on the mechanism of electroweak symmetry breaking. An important […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Torsten Åkesson, Nikita Blinov, Lukas Brand-Baugher, Cameron Bravo, Lene Kristian Bryngemark | Summary: The constituents of dark matter are still unknown, and the viable possibilities span a vast range of masses. The physics community has established searching for sub-GeV dark matter as a high priority and identified […]

Kavli Affiliate: Scott P. Wakely | First 5 Authors: Colin B. Adams, Giovanni Ambrosi, Michelangelo Ambrosio, Carla Aramo, Timothy Arlen | Summary: The prototype Schwarzschild-Couder Telescope (pSCT) is a candidate for a medium-sized telescope in the Cherenkov Telescope Array. The pSCT is based on a novel dual mirror optics design which reduces the plate scale […]
