Kavli Affiliate: Mark Vogelsberger | First 5 Authors: , , , , | Summary: We study the impact of warm dark matter (WDM) particle mass on galaxy properties using 1,024 state-of-the-art cosmological hydrodynamical simulations from the DREAMS project. We begin by using a Multilayer Perceptron (MLP) coupled with a normalizing flow to explore global statistical […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Kai Wu, Kai Wu, , , | Summary: As a continuation of DRAGON-II, we present the DRAGON-III project, which focuses on the simulations of million-body globular clusters and nuclear clusters over 10 Gyr. We report on its preliminary results on globular clusters. The first 100 Myr of […]
Kavli Affiliate: Katrin Heitmann | First 5 Authors: Nicholas Frontiere, Nicholas Frontiere, , , | Summary: Resolving the most fundamental questions in cosmology requires simulations that match the scale, fidelity, and physical complexity demanded by next-generation sky surveys. To achieve the realism needed for this critical scientific partnership, detailed gas dynamics, along with a host […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: , , , , | Summary: We report statistically significant detection of H I 21-cm emission from intermediate-redshift ($zapprox0.2$-0.6) galaxies. By leveraging multi-sightline galaxy survey data from the Cosmic Ultraviolet Baryon Survey (CUBS) and deep radio observations from the MeerKAT Absorption Line Survey (MALS), we have […]
Kavli Affiliate: Jing Wang | First 5 Authors: Peng Chen, Peng Chen, , , | Summary: In this paper, we investigate the Milstein numerical scheme with step size $eta$ for a stochastic differential equation driven by multiplicative Brownian motion. Under some appropriate coefficient conditions, the continuous-time system and its discrete Milstein scheme approximation each possess […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: , , , , | Summary: We present the analysis of the intracluster light (ICL) in three fossil groups (FG), RXJ085640.72+055347.36, RX J1136+0713, and RX J1410+4145, at z ~ 0.1. We used two optical broad-band filters, F435W and F606W, observed with the Hubble Space Telescope and […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Feng Yuan, , , | Summary: Cross-modal medical image synthesis research focuses on reconstructing missing imaging modalities from available ones to support clinical diagnosis. Driven by clinical necessities for flexible modality reconstruction, we explore K to N medical generation, where three critical challenges emerge: How […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Xiaoyang Chen, Xiaoyang Chen, , , | Summary: One of the most remarkable discoveries of JWST is a population of compact, red sources at z > 4, commonly referred to as Little Red Dots (LRDs). Spectroscopic identifications reported that most LRDs are active galactic nuclei (AGNs), which […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Tamjid Al Rahat, Tamjid Al Rahat, , , | Summary: OpenID Connect has revolutionized online authentication based on single sign-on (SSO) by providing a secure and convenient method for accessing multiple services with a single set of credentials. Despite its widespread adoption, critical security bugs in OpenID […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Sanna Gulati, Sanna Gulati, , , | Summary: We present results from uGMRT 685 MHz observations of 87 QSOs belonging to the Palomar Green (PG) quasar sample with $z<0.5$. Radio emission is detected in all sources except for 3 radio-quiet (RQ) sources, viz., PG 0043+039, PG […]
