Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Nithyanandan Thyagarajan, Chris L. Carilli, Bojan Nikolic, James Kent, Andrei Mesinger | Summary: Characterizing the epoch of reionization (EoR) at $zgtrsim 6$ via the redshifted 21 cm line of neutral Hydrogen (HI) is critical to modern astrophysics and cosmology, and thus a key science goal of […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Silviu-Marian Udrescu, Max Tegmark, , , | Summary: We present a method for unsupervised learning of equations of motion for objects in raw and optionally distorted unlabeled video. We first train an autoencoder that maps each video frame into a low-dimensional latent space where the laws of […]

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Nolan Denman, Andre Renard, Keith Vanderlinde, Philippe Berger, Kiyoshi Masui | Summary: We present an overview of the Graphics Processing Unit (GPU) based spatial processing system created for the Canadian Hydrogen Intensity Mapping Experiment (CHIME). The design employs AMD S9300x2 GPUs and readily-available commercial hardware in its […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Maulik Parikh, Frank Wilczek, George Zahariade, , | Summary: We show that when the gravitational field is treated quantum-mechanically, it induces fluctuations — noise — in the lengths of the arms of gravitational wave detectors. The characteristics of the noise depend on the quantum state of the […]

Kavli Affiliate: Edward H. Morgan | First 5 Authors: Carolina von Essen, Mikkel N. Lund, Rasmus Handberg, Marina S. Sosa, Julie Thiim Gadeberg | Summary: The Transiting Exoplanet Survey Satellite (TESS) is NASA’s latest space telescope dedicated to the discovery of transiting exoplanets around nearby stars. Besides the main goal of the mission, asteroseismology is […]
