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 […]

Neutron Star Mergers as the Dominant Contributor to the Production of Heavy $r$-Process Elements

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li |Summary:The discovery of the radioactively powered kilonova AT2017gfo, associated with the short-duration gamma-ray burst GRB 170817A and the gravitational wave source GW170817, has provided the first direct evidence supporting binary neutron star mergers as crucial astrophysical sites for the synthesis of heavy elements beyond iron through $r$-process nucleosysthesis in the […]

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 dbos 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 at $z=0$ with Illustris TNG300 hydrodynamic simulation data. We predict stellar masses from subhalo properties to test two types of machine […]

The TESS-Keck Survey XXI: 13 New Planets and Homogeneous Properties for 21 Subgiant Systems

Posted by klaurent MIT

Kavli Affiliate: Robert Goeke | Summary:We present a dedicated transit and radial velocity survey of planets orbiting subgiant stars observed by the TESS Mission. Using $sim$$16$ nights on Keck/HIRES, we confirm and characterize $12$ new transiting planets — $rm TOI-329,b$, $rm HD,39688,b$ ($rm TOI-480$), $rm TOI-603,b$, $rm TOI-1199,b$, $rm TOI-1294,b$, $rm TOI-1439,b$, $rm TOI-1605,b$, $rm […]
