EchoRec: Multi-Item Prediction-Empowered Generative Recommendation via Cycle-Consistent Preference Alignment
Haokai Ma, Aoqi Hu, Yueao Xing +5
Generative recommendation autoregressively generates the semantic IDs of the target item, unifying preference modeling and index retrieval within the shared token space. Recent att…
Kinematic scaling of thin and thick discs from SAMI to NewHorizon
Sree Oh, J. K. Jang, Giulia Santucci +8
We revisit the relation between disc stellar mass and disc velocity dispersion (M_*-Ï_e) and extend it to thin and thick subcomponents using orbit-based dynamical models of 161 SA…
Orbital decomposition of the nuclear regions in the early-type galaxy FCC 47: Unveiling the nuclear cluster origin
Julia Lamprecht, Anja Feldmeier-Krause, Mariya Lyubenova +8
Nuclear star clusters (NSCs) are among the densest stellar systems in the Universe and often coexist with supermassive black holes (SMBHs) at galaxy centres. While SMBH formation h…
The SAMI Galaxy Survey: large-scale environment affects galaxy spin amplitudes and the formation of slow rotators
Stefania Barsanti, Scott M. Croom, Matthew Colless +9
We explore the impact of the large-scale 3D density field, as defined by deep, wide-field galaxy surveys, on stellar spin () and the distributions of fast and slow ro…
The MAGPI Survey: the kinematic morphology-density relation (or lack thereof) and the Hubble sequence at
Caroline Foster, Mark W. Donoghoe, Andrew Battisti +26
This work presents visual morphological and dynamical classifications for 637 spatially resolved galaxies, most of which are at intermediate redshift (), in the Middle-Ag…
