Kavli Affiliate: Xian Chen | First 5 Authors: Liang-Gui Zhu, Xian Chen, , , | Summary: Dark sirens, i.e., gravitational-wave (GW) sources without electromagnetic counterparts, are new probes of the expansion of the universe. The efficacy of this method relies on correctly localizing the host galaxies. However, recent theoretical studies have shown that astrophysical environments […]
Kavli Affiliate: Jia Liu | First 5 Authors: Pin Ji, Yang Feng, Weitao Huang, Jia Liu, Zhihong Zhao | Summary: The development of modern NLP applications often relies on various benchmark datasets containing plenty of manually labeled tests to evaluate performance. While constructing datasets often costs many resources, the performance on the held-out data may […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jakob M. Helton, Fengwu Sun, Charity Woodrum, Kevin N. Hainline, Christopher N. A. Willmer | Summary: We report the discovery of an extreme galaxy overdensity at $z = 5.4$ in the GOODS-S field using JWST/NIRCam imaging from JADES and JEMS alongside JWST/NIRCam wide field slitless spectroscopy from […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Melissa J. Hobson, Andrés Jordán, E. M. Bryant, R. Brahm, D. Bayliss | Summary: We present the discovery of TOI-3235 b, a short-period Jupiter orbiting an M-dwarf with a stellar mass close to the critical mass at which stars transition from partially to fully convective. TOI-3235 […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Anna Frebel, Alexander P. Ji, , , | Summary: This chapter presents an overview of the recent progress on spectroscopic observations of metal-poor stars with r-process element signatures found in the Milky Way’s stellar halo and satellite dwarf galaxies. Major empirical lessons related to the origins of […]
Kavli Affiliate: Salman Habib | First 5 Authors: James M. Sullivan, J. D. Emberson, Salman Habib, Nicholas Frontiere, | Summary: Neutrino mass constraints are a primary focus of current and future large-scale structure (LSS) surveys. Non-linear LSS models rely heavily on cosmological simulations — the impact of massive neutrinos should therefore be included in these […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: M. F. Albakry, I. Alkhatib, D. Alonso, D. W. P. Amaral, T. Aralis | Summary: We present a new analysis of previously published of SuperCDMS data using a profile likelihood framework to search for sub-GeV dark matter (DM) particles through two inelastic scattering channels: bremsstrahlung radiation […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Pascal M. Keller, Bojan Nikolic, Nithyanandan Thyagarajan, Chris L. Carilli, Gianni Bernardi | Summary: Radio interferometers aiming to measure the power spectrum of the redshifted 21 cm line during the Epoch of Reionisation (EoR) need to achieve an unprecedented dynamic range to separate the weak signal […]

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Mayuko Yamashita, Kazuya Yonekura, , | Summary: For physicists: For supersymmetric quantum mechanics, there are cases when a mod-2 Witten index can be defined, even when a more ordinary $mathbb{Z}$-valued Witten index vanishes. Similarly, for 2d supersymmetric quantum field theories, there are cases when a […]
