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…
Exploring the observed properties of JWST Little Red Dots with cosmological simulations and dust radiative transfer
Saksham Chandna, Fabio Di Mascia, Simona Gallerani +6
JWST has uncovered compact high-redshift (z>=4) sources, dubbed Little Red Dots (LRDs), characterised by a distinct V-shaped continuum. Their nature remains debated since broad-lin…
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 Multiphase CGM in the Epoch of Reionization: CII and CIV absorbers around [OIII] Emitters
C. Piscitelli, V. D'Odorico, M. Galbiati +17
We investigate the multiphase circumgalactic medium (CGM) during the Epoch of Reionization (EoR, ) by cross-correlating cool- CII and warm-ionized CIV absorption systems with…
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…
AGN X-ray coronae at high luminosity: A broadband study of RBS 229 and PG 1407+265
Alessandro Leonardo Lai, Stefano Bianchi, Andrea Marinucci +8
Context. The X-ray emission of active galactic nuclei (AGNs) is commonly interpreted as arising from Comptonisation in a hot corona above the accretion disc. A prominent soft X-ray…
