The Cepheid Distance to the Seyfert 1 Galaxy NGC 4151

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Wenlong Yuan, Michael M. Fausnaugh, Samantha L. Hoffmann, Lucas M. Macri, Bradley M. Peterson | Summary: We derive a distance of $15.8pm0.4$ Mpc to the archetypical Seyfert 1 galaxy NGC 4151 based on the near-infrared Cepheid Period-Luminosity relation and new Hubble Space Telescope multiband imaging. This […]

Inferring the properties of a population of compact binaries in presence of selection effects

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Salvatore Vitale, Davide Gerosa, Will M. Farr, Stephen R. Taylor, | Summary: Shortly after a new class of objects is discovered, the attention shifts from the properties of the individual sources to the question of their origin: do all sources come from the same underlying population, or […]

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 […]
