The R-Process Alliance: Chemo-Dynamically Tagged Groups of Halo $r$-Process-Enhanced Stars Reveal a Shared Chemical-Evolution History

Kavli Affiliate: Anna Frebel | First 5 Authors: Dmitrii Gudin, Derek Shank, Timothy C. Beers, Zhen Yuan, Guilherme Limberg | Summary: We derive dynamical parameters for a large sample of 446 $r$-process-enhanced (RPE) metal-poor stars in the halo and disk systems of the Milky Way, based on data releases from the $R$-Process Alliance, supplemented by […]

Observables for Recoil Identification in High-Definition Gas Time Projection Chambers

Kavli Affiliate: Cosmin Deaconu | First 5 Authors: Majd Ghrear, Sven E. Vahsen, Cosmin Deaconu, , | Summary: Directional detection of nuclear recoils is broadly desirable in nuclear and particle physics. At low recoil energies, this capability may be used to confirm the cosmological origin of a dark matter signal, to penetrate the so-called neutrino […]

RR Lyrae variables in Messier 53: Near-infrared Period–Luminosity relations and the calibration using Gaia Early Data Release 3

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anupam Bhardwaj, Marina Rejkuba, Richard de Grijs, Soung-Chul Yang, Gregory J. Herczeg | Summary: We present new near-infrared, $JHK_s$, Period–Luminosity relations (PLRs) for RR Lyrae variables in the Messier 53 (M53 or NGC 5024) globular cluster. Multi-epoch $JHK_s$ observations, obtained with the WIRCam instrument on the […]

A transport approach to relate asymmetric protein segregation and population growth

Kavli Affiliate: Ariel Amir | First 5 Authors: Jiseon Min, Ariel Amir, , , | Summary: Many unicellular organisms allocate their key proteins asymmetrically between the mother and daughter cells, especially in a stressed environment. A recent theoretical model is able to predict when the asymmetry in segregation of key proteins enhances the population fitness, […]

Amorphous topological phases protected by continuous rotation symmetry

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Anton R. Akhmerov, Daniel Varjas, , | Summary: Protection of topological surface states by reflection symmetry breaks down when the boundary of the sample is misaligned with one of the high symmetry planes of the crystal. We demonstrate that this limitation is removed in […]

The role of disorder in the synthesis of metastable zinc zirconium nitrides

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Vladan Stevanović, Stephan Lany, Karen N. Heinselman, Matthew K. Horton | Summary: In materials science, it is often assumed that ground state crystal structures predicted by density functional theory are the easiest polymorphs to synthesize. Ternary nitride materials, with many possible metastable polymorphs, provide […]

Direct Observation of Thermalization to a Rayleigh-Jeans Distribution in Multimode Optical Fibers

Kavli Affiliate: Frank Wise | First 5 Authors: Hamed Pourbeyram, Pavel Sidorenko, Fan Wu, Nicholas Bender, Logan Wright | Summary: Recent years have witnessed a resurgence of interest in nonlinear multimode optical systems where a host of intriguing effects have been observed that are impossible in single-mode settings. While nonlinearity can provide a rich environment […]

Direct Measurement of Thermalization to Rayleigh-Jeans Distribution in Optical Beam Self-Cleaning

Kavli Affiliate: Frank Wise | First 5 Authors: Hamed Pourbeyram, Pavel Sidorenko, Fan Wu, Logan Wright, Demetrios Christodoulides | Summary: An equilibrium thermodynamic framework that describes highly-multimode optical processes was introduced recently. This theory predicts the outcomes of complex linear and nonlinear multimode interactions based on thermodynamic principles and provides analytic results for the distributions […]

X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary

Kavli Affiliate: Fukun Liu | First 5 Authors: Xinwen Shu, Wenjie Zhang, Shuo Li, Ning Jiang, Liming Dou | Summary: Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or […]
