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 […]

Mass loss from massive globular clusters in tidal fields

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Yohai Meiron, Jeremy J. Webb, Jongsuk Hong, Peter Berczik, Rainer Spurzem | Summary: Massive globular clusters lose stars via internal and external processes. Internal processes include mainly two-body relaxation, while external processes include interactions with the Galactic tidal field. We perform a suite of N-body simulations of […]

High-throughput search for magnetic and topological order in transition metal oxides

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Nathan C. Frey, Matthew K. Horton, Jason M. Munro, Sinéad M. Griffin, Kristin A. Persson | Summary: The discovery of intrinsic magnetic topological order in $rm MnBi_2Te_4$ has invigorated the search for materials with coexisting magnetic and topological phases. These multi-order quantum materials are expected to […]

Will LISA Detect Harmonic Gravitational Waves from Galactic Cosmic String Loops?

Kavli Affiliate: Craig J. Hogan | First 5 Authors: Zimu Khakhaleva-Li, Craig J. Hogan, , , | Summary: Rapid advancement in the observation of cosmic strings has been made in recent years placing increasingly stringent constraints on their properties, with $Gmulesssim 10^{-11}$ from Pulsar Timing Array (PTA). Cosmic string loops with low string tension clump […]

New bounds on macroscopic scalar-field topological defects from non-transient signatures due to environmental dependence and spatial variations of the fundamental constants

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Yevgeny V. Stadnik, , , , | Summary: We point out that in models of macroscopic topological defects composed of one or more scalar fields that interact with standard-model fields via scalar-type couplings, the back-action of ambient matter on the scalar field(s) produces an environmental dependence […]

Automated Measurements of Key Morphological Features of Human Embryos for IVF

Kavli Affiliate: Daniel Needleman | First 5 Authors: Brian D. Leahy, Won-Dong Jang, Helen Y. Yang, Robbert Struyven, Donglai Wei | Summary: A major challenge in clinical In-Vitro Fertilization (IVF) is selecting the highest quality embryo to transfer to the patient in the hopes of achieving a pregnancy. Time-lapse microscopy provides clinicians with a wealth […]

Quantifying the statistics of CMB-lensing-derived galaxy cluster mass measurements with simulations

Kavli Affiliate: Anthony Challinor | First 5 Authors: Íñigo Zubeldia, Anthony Challinor, , , | Summary: CMB lensing is a promising, novel way to measure galaxy cluster masses that can be used, e.g., for mass calibration in galaxy cluster counts analyses. Understanding the statistics of the galaxy cluster mass observable obtained with such measurements is […]
