Ultra-diffuse galaxies in the EAGLE simulation

Haonan Zheng, Shihong Liao, Liang Gao, Fangzhou Jiang, | Summary: [[{“value”:”We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultra-diffuse galaxies (UDGs). We identify 181 UDGs and find their properties closely match observations. The total masses of EAGLE UDGs range from ${sim}5times 10^{8}~M_{odot}$ to ${sim}2times 10^{11}~M_{odot}$, indicating that they are […]

Geometry of Kinematic Flow

Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Harry Goodhew, Austin Joyce, Hayden Lee, Guilherme L. Pimentel | Summary: We uncover a geometric organization of the differential equations for the wavefunction coefficients of conformally coupled scalars in power-law cosmologies. To do this, we introduce a basis of functions inspired by a decomposition of […]

AlignRAG: An Adaptable Framework for Resolving Misalignments in Retrieval-Aware Reasoning of RAG

Kavli Affiliate: Xiang Zhang | First 5 Authors: Jiaqi Wei, Hao Zhou, Xiang Zhang, Di Zhang, Zijie Qiu | Summary: Retrieval-augmented generation (RAG) has emerged as a foundational paradigm for knowledge-grounded text generation. However, existing RAG pipelines often fail to ensure that the reasoning trajectories align with the evidential constraints imposed by retrieved content. In […]

Survey of hippocampal responses to sound in naive mice reveals widespread activation by broadband noise onsets

Kavli Affiliate: Andrea Hasenstaub | Authors: James Bigelow, Toshiaki Suzuki, Yulang Wu, Ying Hu and Andrea R Hasenstaub | Summary: Recent studies suggest some hippocampal (HC) neurons respond to passively presented sounds in naive subjects, but the specificity and prevalence of these responses remain unclear. We used Neuropixels probes to record unit activity in HC […]
