Kavli Affiliate: Stephan S. Meyer | First 5 Authors: Jonathan W. Richardson, Ohkyung Kwon, H. Richard Gustafson, Craig Hogan, Brittany L. Kamai | Summary: Precision measurements are reported of the cross-spectrum of rotationally-induced differential position displacements in a pair of colocated 39 m long, high power Michelson interferometers. One arm of each interferometer is bent […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: , , , , | Summary: Observations of the $gamma$-ray emission around star clusters, isolated supernova remnants, and pulsar wind nebulae indicate that the cosmic-ray (CR) diffusion coefficient near acceleration sites can be suppressed by a large factor compared to the Galaxy average. We explore the […]
Kavli Affiliate: Elise Jennings | First 5 Authors: Romit Maulik, Himanshu Sharma, Saumil Patel, Bethany Lusch, Elise Jennings | Summary: We outline the development of a data science module within OpenFOAM which allows for the in-situ deployment of trained deep learning architectures for general-purpose predictive tasks. This module is constructed with the TensorFlow C API […]
Kavli Affiliate: Brian Nord | First 5 Authors: Luisa Lucie-Smith, Hiranya V. Peiris, Andrew Pontzen, Brian Nord, Jeyan Thiyagalingam | Summary: While the evolution of linear initial conditions present in the early universe into extended halos of dark matter at late times can be computed using cosmological simulations, a theoretical understanding of this complex process […]
Kavli Affiliate: Brian Nord | First 5 Authors: Luisa Lucie-Smith, Hiranya V. Peiris, Andrew Pontzen, Brian Nord, Jeyan Thiyagalingam | Summary: The evolution of linear initial conditions present in the early universe into extended halos of dark matter at late times can be computed using cosmological simulations. However, a theoretical understanding of this complex process […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Gourav Khullar, Katya Gozman, Jason J. Lin, Michael N. Martinez, Owen S. Matthews Acuña | Summary: We report the discovery of COOL J1241+2219, a strongly-lensed galaxy at redshift $z$=5.043$pm$0.002 with observed magnitude $z_{AB}=20.47$, lensed by a moderate-mass galaxy cluster at $z$=1.001$pm$0.001. COOL J1241+2219 is the brightest […]
Kavli Affiliate: Albert Stebbins | First 5 Authors: Fengquan Wu, Jixia Li, Shifan Zuo, Xuelei Chen, Santanu Das | Summary: The Tianlai Dish Pathfinder Array is a radio interferometer designed to test techniques for 21~cm intensity mapping in the post-reionization universe as a means for measuring large-scale cosmic structure. It performs drift scans of the […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Maximilian H. Abitbol, David Alonso, Sara M. Simon, Jack Lashner, Kevin T. Crowley | Summary: We quantify the calibration requirements for systematic uncertainties for next-generation ground-based observatories targeting the large-angle $B$-mode polarization of the Cosmic Microwave Background, with a focus on the Simons Observatory (SO). We explore […]
Kavli Affiliate: Michael Gladders | First 5 Authors: Peter R. Williams, Tommaso Treu, Håkon Dahle, Stefano Valenti, Louis Abramson | Summary: We present the first results of a 4.5 year monitoring campaign of the three bright images of multiply imaged $z=2.805$ quasar SDSS J2222+2745 using the Gemini North Multi-Object Spectrograph (GMOS-N) and the Nordic Optical […]
Kavli Affiliate: Donald York | First 5 Authors: Chen Chen, Fred Hamann, Bo Ma, Britt Lundgren, Donald York | Summary: The early stage of massive galaxy evolution often involves outflows driven by a starburst or a central quasar plus cold mode accretion (infall), which adds to the mass build-up in the galaxies. To study the […]
