21. COSMO: Beyond the black-body Cosmic Microwave Background, towards the detection of spectral distortions

Alessandro Capponi (Ca' Foscari University of Venice, Sapienza University of Rome, INFN - Sez. Roma)

The Cosmic Microwave Background (CMB) provides a window into the thermal history of the early Universe. Deviations from a perfect black-body spectrum, known as spectral distortions, carry unique signatures of early physical processes. Yet, despite their significance, no primordial spectral distortions have been detected to date, and the most stringent limits remain those set by the COBE/FIRAS...

6. (Talk Canceled) Kinematics of Coronal Mass Ejections: Leveraging Antarctic Observational Platforms for Enhanced Space Weather Monitoring.

Coronal Mass Ejections (CMEs) are large-scale solar eruptions capable of triggering severe space weather events, particularly impacting high-latitude regions such as the polar zones. Accurate determination of CME kinematics—velocity, acceleration, and trajectory—is critical for early warning systems and for understanding the solar-terrestrial interaction. In this study, I analyze the kinematic...

In light of the available evidence, Dome A is known as one of the best ground-based observatory sites in the world. In order to leverage the advantages offered by the atmospheric boundary layer, which has an average height of 13.9 meters, for enhanced observation capabilities, a tower is to be constructed with a height of 15 meters above ground level to elevate the telescope. Nevertheless, the...

10. Investigating Ice Drilling Performance in the Firn Layer at the South Pole

Dr Chana Sinsabvarodom (Chiang Mai University)

This research aims to assess the effectiveness of ice drilling operations within the firn layer at the South Pole for the IceCube Upgrade Project to install neutrino detectors below the Antarctic ice. This firn drill consists of a melting probe of 60 cm diameter. Field experiments carried out during the 2024–2025 summer season highlighted the importance of maintaining a balance between the...

19. The Antarctic Geospace and ATmosphere reseArch (AGATA SCAR Scientific Research Programme) and their links with the Astronomy community

Adriana Maria Gulisano (IAA/DNA, IAFE(CONICET-UBA), UBA FCEyN DF)

The AGATA programme is a newly endorsed SCAR initiative aimed at advancing the understanding of Sun–Earth interactions and polar atmosphere dynamics through coordinated international research. After more than a decade without a dedicated SCAR programme in this area, AGATA addresses key questions in space and atmospheric physics, including atmospheric coupling, ionospheric response to...
