A core in a star-forming disc as evidence of inside-out growth in the early Universe

Posted by dbos June 4, 2023Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: William M. Baker, Sandro Tacchella, Benjamin D. Johnson, Erica Nelson, Katherine A. Suess | Summary: The physical processes that establish the morphological evolution and the structural diversity of galaxies are key unknowns in extragalactic astrophysics. Here we report the finding of the morphologically-mature galaxy JADES-GS+53.18343-27.79097, which existed […]

JADES: The emergence and evolution of Ly$α$ emission and constraints on the IGM neutral fraction

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Gareth C. Jones, Andrew J. Bunker, Aayush Saxena, Joris Witstok, Daniel P. Stark | Summary: The rest-frame UV recombination emission line Ly$alpha$ can be powered by ionising photons from young massive stars in star forming galaxies, but its ability to be resonantly scattered by neutral gas complicates […]

Realization of two-sublattice exchange physics in the triangular lattice compound Ba3Er(BO3)3

Posted by klaurent June 4, 2023UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Matthew Ennis, Rabindranath Bag, Chunxiao Liu, Sachith E. Dissanayake, Alexander I. Kolesnikov | Summary: We have synthesized high-quality single crystal samples of the erbium-based triangular lattice compound Ba3Er(BO3)3. Thermal and magnetic measurements reveal large anisotropy and a possible phase transition at 100 mK. The low-temperature magnetic heat […]

Manipulating chiral-spin transport with ferroelectric polarization

Posted by klaurent June 3, 2023Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Xiaoxi Huang, Xianzhe Chen, Yuhang Li, John Mangeri, Hongrui Zhang | Summary: A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more than nine decades ago, has always been manipulated […]
