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…
The WISSHFUL program: the highest redshift UFO discovered in a non-lensed QSO
G. Lanzuisi, L. Borrelli, E. Piconcelli +28
We present the first results from the WISSHFUL program, an XMM-Newton heritage program targeting luminous QSOs at Cosmic Noon. We report on recent simultaneous XMM-Newton and NuSTA…
A deep X-ray look to the most obscured quasar at z~3.6 and its environment
I. Villani, L. Zappacosta, E. Piconcelli +17
The most luminous and obscured quasars (QSOs) detected in infrared all-sky surveys could represent a key co-evolutionary phase from nuclear to circum-galactic (CG) scales in the fo…
The WISSH quasar project. XII. X-ray view of the most luminous quasi-stellar objects at Cosmic Noon
C. Degli Agosti, C. Vignali, E. Piconcelli +25
To improve our knowledge of nuclear emission in luminous QSOs at Cosmic Noon, we studied the X-ray emission of the WISE/SDSS-selected hyper-luminous (WISSH) QSO sample: 85 broad-li…
HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe
I. Saccheo, A. Bongiorno, E. Piconcelli +41
We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…
HYPERION. Shedding light on the first luminous quasars: A correlation between UV disc winds and X-ray continuum
A. Tortosa, L. Zappacosta, E. Piconcelli +41
One of the main open questions in the field of luminous () quasars (QSOs) at is the rapid formation (Gyr) of their superm…
HYPerluminous quasars at the Epoch of ReionizatION (HYPERION). A new regime for the X-ray nuclear properties of the first quasars
L. Zappacosta, E. Piconcelli, F. Fiore +40
The existence of luminous quasars (QSO) at the Epoch of Reionization (EoR; i.e. z>6) powered by supermassive black holes (SMBH) with masses challenges models…
