Design Studies Of A Pulsed Quasimonoenergetic 2-keV Neutron Source For Calibration Of Low Threshold Dark Matter Detectors

Posted by klaurent October 15, 2024Stanford

Kavli Affiliate: Roger Romani | Summary:We describe design studies for a pulsed quasi-monoenergetic 2-keV neutron source for calibration of sub-keV nuclear recoils. Such a calibration is required for detectors sensitive to sub- GeV dark matter and also the coherent elastic scattering of reactor neutrinos. In our design, neutrons from a commercial deuterium-tritium generator are moderated […]

TESS Giants Transiting Giants. VII. A Hot Saturn Orbiting an Oscillating Red Giant Star

Posted by klaurent October 14, 2024MIT

Kavli Affiliate: Alan Levine | Summary:We present the discovery of TOI-7041 b (TIC 201175570 b), a hot Saturn transiting a red giant star with measurable stellar oscillations. We observe solar-like oscillations in TOI-7041 with a frequency of maximum power of $ν_rm max = 218.50pm2.23$ $μ$Hz and a large frequency separation of $Δν= 16.5282pm0.0186$ $μ$Hz. Our […]

GA-NIFS & EIGER: A merging quasar host at z=7 with an overmassive black hole

Posted by dbos October 14, 2024MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Madeline A. Marshall, Minghao Yue, Anna-Christina Eilers, Jan Scholtz, Michele Perna | Summary: The James Webb Space Telescope is revolutionising our ability to understand the host galaxies and local environments of high-z quasars. Here we obtain a comprehensive understanding of the host galaxy of the z=7.08 […]

A systematic search for rapid transients in the Subaru HSC-SSP transient survey

Posted by klaurent October 14, 2024Tokyo

Kavli Affiliate: Naoki Yasuda | Summary:Recent high-cadence transient surveys have discovered rapid transients whose light curve timescales are shorter than those of typical supernovae. In this paper, we present a systematic search for rapid transients at medium-high redshifts among 3381 supernova candidates obtained from the Subaru HSC-SSP transient survey. We developed a machine learning classifier […]

Cosmological and Astrophysical Parameter Inference from Stacked Galaxy Cluster Profiles Using CAMELS-zoomGZ

Posted by dbos October 14, 2024October 28, 2024Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Elena Hernández-Martínez, Shy Genel, Francisco Villaescusa-Navarro, Ulrich P. Steinwandel, Max E. Lee | Summary: We present a study on the inference of cosmological and astrophysical parameters using stacked galaxy cluster profiles. Utilizing the CAMELS-zoomGZ simulations, we explore how various cluster properties–such as X-ray surface brightness, gas […]

From Anchors to Answers: A Novel Node Tokenizer for Integrating Graph Structure into Large Language Models

Posted by klaurent October 14, 2024Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: , , , , | Summary: Enabling large language models (LLMs) to effectively process and reason with graph-structured data remains a significant challenge despite their remarkable success in natural language tasks. Current approaches either convert graph structures into verbose textual descriptions, consuming substantial computational resources, or employ […]

Dynamics of McMillan mappings III. Symmetric map with mixed nonlinearity

Posted by klaurent October 14, 2024Tokyo

Kavli Affiliate: Young-kee Kim | Summary:This article extends the study of dynamical properties of the symmetric McMillan map, emphasizing its utility in understanding and modeling complex nonlinear systems. Although the map features six parameters, we demonstrate that only two are irreducible: the linearized rotation number at the fixed point and a nonlinear parameter representing the […]
