Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: $AdS_3$ string theory in the stringy regime $k=(R_{AdS}/ell_{str})^2 < 1$ provides a laboratory for the study of holography in which both sides of AdS/CFT duality are under fairly good control. Worldsheet string theory is solvable, and for closed […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Guy C. Moore, Matthew K. Horton, Alexander M. Ganose, Martin Siron, Kristin A. Persson | Summary: Hubbard U and Hund J values provide a measure of the self-interaction between correlated electrons, and are crucial parameters in the formalism of density functional theory with a "plus U" […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Paul A. Dalba, Stephen R. Kane, Diana Dragomir, Steven Villanueva Jr., Karen A. Collins | Summary: We report the discovery of TOI-2180 b, a 2.8 $M_{rm J}$ giant planet orbiting a slightly evolved G5 host star. This planet transited only once in Cycle 2 of the […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Andrina Nicola, Francisco Villaescusa-Navarro, David N. Spergel, Jo Dunkley, Daniel Anglés-Alcázar | Summary: Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics that are robust against these uncertainties, or constrain these […]
Kavli Affiliate: Alan M. Levine | First 5 Authors: Samuel K. Grunblatt, Nicholas Saunders, Meng Sun, Ashley Chontos, Melinda Soares-Furtado | Summary: Giant planets on short-period orbits are predicted to be inflated and eventually engulfed by their host stars. However, the detailed timescales and stages of these processes are not well known. Here we present […]
