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…

Toward the Italian Astronomical Community's Contribution to HWO: Science, Technology, and Instrument Concepts

A. Fontana, F. Annibali, N. Antonietti +101

This paper summarizes the interest of the Italian astronomical community in the possible participation in the development of the Habitable Worlds Observatory (HWO). It is largely b…

The small transiting planet population revealed by ESPRESSO with extreme precision radial velocities

M. J. Hobson, B. Lavie, F. Bouchy +35

Small planets are extremely common in the Galaxy, including planets with masses and radii between those of Earth and Neptune. Characterizing these planets' masses requires ultra-pr…

Estimating the completeness of the QUBRICS Survey with 3501 QSO redshifts from Gaia DR3 spectra

Matteo Porru, Stefano Cristiani, Francesco Guarneri +9

QSOs are essential for investigating the structure and evolution of the Universe. Historically, their identification has been concentrated in the northern hemisphere, primarily due…

The ESPRESSO Redshift Drift Experiment III -- The Third Epoch of QSO J052915.80-435152.0

Andrea Trost, Catarina M. J. Marques, S. Cristiani +25

The Sandage-Loeb test probes cosmic expansion directly by measuring the redshift drift in quasar absorption features in a model-independent way. In this series of papers, we have l…

One H2 molecule per ten million H-atoms reveals sub-pc scale cold overdensities at z~4

P. Noterdaeme, S. Balashev, T. Berg +11

We present the detection and analysis of H2 absorption at z = 4.24 towards the bright quasar J0007-5705, observed with the Very Large Telescope as part of the ESPRESSO QUasar Absor…

E-XQR-30: Evidence for an Increase in the Ionization State of Metal Absorbers from z~6 to z~2

Stephanie Rowlands, R. L. Davies, E. Ryan-Weber +15

We investigate the evolution of the ionization state of metal-enriched gas in and around galaxies near the epoch of reionization using a sample of 488 metal absorption systems at 4…
