Survey of Gravitationally lensed Objects in HSC Imaging (SuGOHI) — VII. Discovery and Confirmation of Three Strongly Lensed Quasars

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Anton T. Jaelani, Cristian E. Rusu, Issha Kayo, Anupreeta More, Alessandro Sonnenfeld | Summary: We present spectroscopic confirmation of three new two-image gravitationally lensed quasars, compiled from existing strong lens and X-ray catalogs. Images of HSC J091843.27$-$022007.5 show a red galaxy with two blue point sources […]

AI Feynman 2.0: Pareto-optimal symbolic regression exploiting graph modularity

Kavli Affiliate: Max Tegmark | First 5 Authors: Silviu-Marian Udrescu, Andrew Tan, Jiahai Feng, Orisvaldo Neto, Tailin Wu | Summary: We present an improved method for symbolic regression that seeks to fit data to formulas that are Pareto-optimal, in the sense of having the best accuracy for a given complexity. It improves on the previous […]

Evidence for magnetic activity at starbirth: a powerful X-ray flare from the Class 0 protostar HOPS 383

Kavli Affiliate: David Principe | First 5 Authors: Nicolas Grosso, Kenji Hamaguchi, David Principe, Joel Kastner, | Summary: Context. Class 0 protostars represent the earliest evolutionary stage of solar-type stars, during which the majority of the system mass resides in an infalling envelope of gas and dust and is not yet in the central, nascent […]

Quantum Algorithm for Approximating Maximum Independent Sets

Kavli Affiliate: Frank Wilczek | First 5 Authors: Hongye Yu, Frank Wilczek, Biao Wu, , | Summary: We present a quantum algorithm for approximating maximum independent sets of a graph based on quantum non-Abelian adiabatic mixing in the sub-Hilbert space of degenerate ground states, which generates quantum annealing in a secondary Hamiltonian. For both sparse […]

Measuring HERA’s primary beam in-situ: methodology and first results

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Chuneeta D. Nunhokee, Aaron R. Parsons, Nicholas S. Kern, Bojan Nikolic, Jonathan C. Pober | Summary: The central challenge in 21~cm cosmology is isolating the cosmological signal from bright foregrounds. Many separation techniques rely on the accurate knowledge of the sky and the instrumental response, including […]

Symbolic Pregression: Discovering Physical Laws from Distorted Video

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 […]
