Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael N. Martinez, Kate A. Napier, Aidan P. Cloonan, Ezra Sukay, Katya Gozman | Summary: In the third paper from the COOL-LAMPS Collaboration, we report the discovery of COOL J0542-2125, a gravitationally lensed quasar at $z=1.84$, observed as three images due to an intervening massive galaxy […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keren Sharon, Guillaume Mahler, T. Emil Rivera-Thorsen, Hakon Dahle, Michael D. Gladders | Summary: We present a strong lensing analysis of the cluster PSZ1 G311.65-18.48, based on Hubble Space Telescope imaging, archival VLT/MUSE spectroscopy, and Chandra X-ray data. This cool-core cluster (z=0.443) lenses the brightest lensed […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Khanh Pham, Andrey Kravtsov, Viraj Manwadkar, , | Summary: We examine the spatial distribution and orbital pole correlations of satellites in a suite of zoom-in high-resolution dissipationless simulations of Miky Way (MW) sized haloes. We use the measured distribution to estimate the incidence of satellite configurations as […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward Basso, Daniel J. H. Chung, Edward W. Kolb, Andrew J. Long, | Summary: Previous numerical investigations of gravitational particle production during the coherent oscillation period of inflation displayed unexplained fluctuations in the spectral density of the produced particles. We argue that these features are due […]
Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Johannes Hubmayr, Jason E. Austermann, James A. Beall, Jake A. Connors, Shannon M. Duff | Summary: Planar Orthomode Transducers (OMTs) are commonly used for polarization measurements at millimeter wavelengths. We present an optical coupling study of an octave bandwidth planar OMT in circular waveguide based on […]
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 […]
