9. Local Dark Matter Density from Improved Local Mass Density of Stars and Updated Baryonic Model

Artem Lutsenko (University of Padova)

Poster contribution

We present a new estimate of the local dark matter density by
combining an updated observational determination of the stellar and
remnant mass density with an updated baryonic model and the Galactic
rotation curve.

The stellar mass density is derived from the Gaia Catalogue of Nearby
Stars within 100 pc using synthetic stellar atmospheres and
evolutionary tracks to compute individual...

72. Multi-Mode BAW Resonators for High-Frequency Gravitational Wave Detection: Electrical Noise Modeling and SQUID Characterization

Riccardo Maifredi

Poster contribution

We present the electrical modeling and preliminary noise characterization of a multi-mode Bulk Acoustic Wave (BAW) gravitational wave detector operating in the 100 kHz–10 MHz frequency range. The detector employs piezoelectric quartz resonators read out by two-stage DC SQUID amplifiers, whose ultra-low-noise performance is essential to approach strain sensitivities at the level of ~10⁻²¹...

41. Next-Generation Nano-Accelerometers for Deep-Space Gravity Science

Fabio Dottavi (University of Milan bicocca)

Poster contribution

Next-generation nano-accelerometers, featuring advanced sensor architectures and integrated front-ends, represent a leap in measuring non-gravitational perturbations like solar radiation pressure during missions to Mercury's orbit. These instruments enable unprecedented precision in spacecraft orbit determination and gravity field recovery up to high degrees, allowing refined models of...

28. The ESPRESSO Redshift Drift Experiment: directly witnessing the cosmological expansion

Andrea Trost

Poster contribution

The Sandage–Loeb test provides a direct and model-independent probe of cosmic expansion by measuring the temporal drift of cosmological redshifts, offering a fundamentally different observable from standard distance-based probes. In this talk, I will present the current status of the ESPRESSO redshift drift experiment, focusing on recent results from the third observational epoch of a bright z...

51. Topological Signal Detection in LISA: A Noise-Agnostic Approach to Gravitational Wave Analysis

Lorenzo Viganò (Università di Trento - Milano-Bicocca)

Poster contribution

A major challenge in LISA data analysis lies in the incomplete characterization of instrumental noise, motivating the development of robust, noise-agnostic detection techniques. In this work, we explore the application of Topological Data Analysis (TDA) as a novel framework for identifying deterministic gravitational wave (GW) signals embedded in noisy data. Our approach leverages Time Delay...
