Distilling Graph Geometry: Knowledge Gap from GNNs to MLPs
Zhewei Chen, Hao Zhu, Jiaojiao Jiang +1
GNN-to-MLP distillation aims to retain the predictive accuracy of a message-passing teacher while deploying a graph-free MLP at inference. Existing methods mainly transfer node-wis…
Constraining the density distribution of the cold Circumgalactic Medium of quasars at z>2 through Lya, HeII and Ha emission
Andrea Travascio, Sebastiano Cantalupo, Titouan Lazeyras +16
Extended Lya emission is routinely detected around high-redshift quasars, revealing large reservoirs of cool circumgalactic medium (CGM). Its resonant nature complicates interpreta…
Multi-tracer constraints on quasar outflows. Acceleration from BLR to galactic scales
M. Brazzini, M. Bischetti, S. Hagen +14
Black hole-driven outflows are a fundamental component of the Active Galactic Nuclei (AGN) paradigm, and may play a major role in regulating the evolution of both supermassive blac…
The WISSH quasars project XIII. A multi-epoch study of ultra-fast broad absorption line outflows at cosmic noon
A. Deconto-Machado, G. Vietri, E. Piconcelli +22
Ultra-fast broad absorption line outflows (uBAL, ~0.1-0.2c) represent some of the most extreme manifestations of quasar-driven winds. We aim to investigate the variability of uBALs…
Constraining AGN accretion physics with black hole mass-luminosity scaling relations
F. Fiore, M. Gaspari, S. Puccetti +3
We test how supermassive black holes are fed by combining new black hole mass-luminosity relations with physically motivated feeding models. We build a uniform sample of 1729 unobs…
The Little Blue and Red Dots Rosetta Stones: Non-Gaussian broad lines, hot dust, and X-ray weakness
M. Brazzini, F. D'Eugenio, R. Maiolino +31
The population of Active Galactic Nuclei (AGN) newly discovered by the James Webb Space Telescope (JWST) exhibits peculiar properties that distinguish it from both local type I AGN…
