Tracking topological defect motion and incommensurate charge order melting in a perovskite manganite

Posted by klaurent Cornell

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Noah Schnitzer, Berit H. Goodge, Gregory Powers, Jaewook Kim, Sang-Wook Cheong | Summary: Charge order pervades the phase diagrams of many quantum materials where it competes with superconducting and magnetic phases, hosts electronic phase transitions and topological defects, and couples to the lattice generating intricate structural […]

Evidence for flare-accelerated particles in large scale loops in the behind-the-limb gamma-ray solar flare of September 29, 2022

Posted by klaurent Stanford

Kavli Affiliate: Nicola Omodei | First 5 Authors: Melissa Pesce-Rollins, Karl-Ludwig Klein, Säm Krucker, Alexander Warmuth, M. Astrid Veronig | Summary: We report on the detection of the gamma-ray emission above 100 MeV from the solar flare of September 29, 2022, by Fermi LAT with simultaneous coverage in HXR by Solar Orbiter STIX. The Solar […]

High-cadence Timing of Binary Pulsars with CHIME

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Chia Min Tan, Emmanuel Fonseca, Kathryn Crowter, Fengqiu Adam Dong, Victoria M. Kaspi | Summary: We performed near-daily observations on the binary pulsars PSR J0218+4232, PSR J1518+4904 and PSR J2023+2853 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). For the first time, we detected the Shapiro […]

Unselfish meiotic drive maintains heterozygosity in a parthenogenetic ant

Posted by klaurent Rockefeller

Kavli Affiliate: Daniel Kronauer | Authors: Kip D Lacy, Taylor Hart and Daniel J.C. Kronauer | Summary: According to Mendel’s second law, chromosomes segregate randomly in meiosis. Non-random segregation is primarily known for cases of selfish meiotic drive in females, in which particular alleles bias their own transmission into the oocyte1,2. Here, we report a […]

How the Galaxy-Halo Connection Depends on Large-Scale Environment

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: John F. Wu, Christian Kragh Jespersen, Risa H. Wechsler, , | Summary: We investigate the connection between galaxies, dark matter halos, and their large-scale environments with Illustris TNG300 hydrodynamic simulation data. We predict stellar masses from subhalo properties to test two types of machine learning (ML) […]

Ephemeris Matching Reveals False Positive Validated and Candidate Planets from the K2 Mission

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Drake A. Lehmann, Andrew Vanderburg, , , | Summary: Data from the Kepler space telescope have led to the discovery of thousands of planet candidates. Most of these candidates are likely to be real exoplanets, but a significant number of false positives still contaminate the sample, especially […]

CHIME/FRB Outriggers: KKO Station System and Commissioning Results

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adam E. Lanman, Shion Andrew, Mattias Lazda, Vishwangi Shah, Mandana Amiri | Summary: Localizing fast radio bursts (FRBs) to their host galaxies is an essential step to better understanding their origins and using them as cosmic probes. The CHIME/FRB Outrigger program aims to add VLBI-localization capabilities […]

Intercalated amygdala dysfunction drives extinction deficits in the Sapap3 mouse model of obsessive-compulsive disorder

Posted by klaurent UCSF

Kavli Affiliate: Anatol Kreitzer | Authors: Robyn St. Laurent, Kelly M Kusche, Anatol C Kreitzer and Robert C Malenka | Summary: Background The avoidance of aversive stimuli due to negative reinforcement learning is critical for survival in real-world environments, which demand dynamic responding to both positive and negative stimuli that often conflict with each other. […]

Flux-tunable Kitaev chain in a quantum dot array

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Juan Daniel Torres Luna, A. Mert Bozkurt, Michael Wimmer, Chun-Xiao Liu, | Summary: Connecting quantum dots through Andreev bound states in a semiconductor-superconductor hybrid provides a platform to create a Kitaev chain. Interestingly, in a double quantum dot, a pair of poor man’s Majorana zero modes can […]
