Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Drew Jamieson, Angelo Caravano, Jiamin Hou, Zachary Slepian, Eiichiro Komatsu | Summary: We introduce the Parity-Odd Power (POP) spectra, a novel set of observables for probing parity violation in cosmological $N$-point statistics. POP spectra are derived from composite fields obtained by applying nonlinear transformations, involving also gradients, […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Michael Boylan-Kolchin, Sandro Tacchella, Rohan P. Naidu | Summary: JWST has revealed a large population of ultra-violet (UV)-bright galaxies at $zgtrsim 10$ and possibly overly massive galaxies at $zgtrsim 7$, challenging standard galaxy formation models in the $Lambda$CDM cosmology. We use an empirical […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ruixuan Xiao, Wentao Ma, Ke Wang, Yuchuan Wu, Junbo Zhao | Summary: LLM-based agents have emerged as promising tools, which are crafted to fulfill complex tasks by iterative planning and action. However, these agents are susceptible to undesired planning hallucinations when lacking specific knowledge for expertise-intensive tasks. […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K Bhowmick, Laura Blecha, Paul Torrey, Rachel S Somerville, Luke Zoltan Kelley | Summary: JWST has recently revealed a large population of accreting black holes (BHs) in the early Universe. Even after accounting for possible systematic biases, the high-z $M_*-M_{rm rm bh}$ relation derived from these […]
Kavli Affiliate: Subo Dong | First 5 Authors: Andrew Gould, Jennifer C. Yee, Subo Dong, , | Summary: Roman microlensing stands at a crossroads between its originally charted path of cataloging a population of cool planets that has subsequently become well-measured down to super-Earths, and the path of free-floating planets (FFPs), which did not exist […]

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Tuomo Salmi, Devarshi Choudhury, Yves Kini, Thomas E. Riley, Serena Vinciguerra | Summary: We report an updated analysis of the radius, mass, and heated surface regions of the massive pulsar PSR J0740+6620 using NICER data from 2018 September 21 to 2022 April 21, a substantial increase in […]

Kavli Affiliate: Jia Liu | First 5 Authors: Yuannan Li, Shan Xu, Jia Liu, , | Summary: The ability to manipulate logical-mathematical symbols (LMS), encompassing tasks such as calculation, reasoning, and programming, is a cognitive skill arguably unique to humans. Considering the relatively recent emergence of this ability in human evolutionary history, it has been […]
