Kavli Affiliate: Austin Joyce | First 5 Authors: Noah Bittermann, Austin Joyce, , , | Summary: We study the structure of the flat space wavefunctional in scalar field theories with nonlinearly realized symmetries. These symmetries imply soft theorems that are satisfied by wavefunction coefficients in the limit where one of the external momenta is scaled […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Hao-Yi Wu, Matteo Costanzi, Chun-Hao To, Andrés N. Salcedo, David H. Weinberg | Summary: Cosmological constraints from current and upcoming galaxy cluster surveys are limited by the accuracy of cluster mass calibration. In particular, optically identified galaxy clusters are prone to selection effects that can bias […]

Kavli Affiliate: Joshua Frieman | First 5 Authors: Anowar J. Shajib, Karl Glazebrook, Tania Barone, Geraint F. Lewis, Tucker Jones | Summary: Imaging data is the principal observable required to use galaxy-scale strong lensing in a multitude of applications in extragalactic astrophysics and cosmology. In this paper, we develop Lensing Exposure Time Calculator (LensingETC) to […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ali Kurmus, Sownak Bose, Mark Lovell, Francis-Yan Cyr-Racine, Mark Vogelsberger | Summary: Observations of the high redshift universe provide a promising avenue for constraining the nature of the dark matter (DM). This will be even more true following the now successful launch of the James Webb Space […]

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Vasily Belokurov, Andrey Kravtsov, , , | Summary: We use accurate estimates of aluminium abundance provided as part of the APOGEE Data Release 17 and Gaia Early Data Release 3 astrometry to select a highly pure sample of stars with metallicity $-1.5lesssim {rm [Fe/H]}lesssim 0.5$ born in-situ […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Iosif Bena, Emil J. Martinec, Samir D. Mathur, Nicholas P. Warner, | Summary: The black-hole information paradox provides a stringent test of would-be theories of quantum gravity. String theory has made significant progress toward a resolution of this paradox, and has led to the fuzzball and […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Yu Qiu, Marie-Lou Gendron-Marsolais, Tamara Bogdanovic, Julie Hlavacek-Larrondo | Summary: The hot intracluster medium (ICM) is thought to be quiescent with low observed velocity dispersions. Surface brightness fluctuations of the ICM also suggest that its turbulence is subsonic with a Kolmogorov scaling relation, indicating that […]
