119. Investigation of pore scale phenomena in CCS applications using X-ray Micro Computed Tomography

Giacomo Luani (NTNU)

Subatomic physics

Oral presentation

The effects of climate change make atmospheric CO2 reductions a necessity. This effort is mostly represented by Carbon Capture and Storage (CCS): the removal of CO2 from the atmosphere and its transport to safe and permanent storage. Injecting, trapping and storing CO2 within the subsurface requires a deep understanding of the geological and geophysical processes that are involved. At the pore...

127. Why is energetic particle precipitation important for climate research and seasonal forecasting?

Hilde Nesse (University of Bergen, Norway)

Oral presentation

Over the past decades, numerous observations and model studies have provided substantial evidence that energetic particle precipitation (EPP) affects the chemistry and dynamics of the stratosphere. Concurrently, the significance of stratospheric dynamics, particularly in winter short-range and seasonal forecasts, has been highlighted. However, there has been little effort to integrate the...

128. The Mesospheric Magnetometry project: Remotely measuring the magnetic field with a laser.

Njål Gulbrandsen (UiT - Norges Arktiske Universitet)

16/06/2025, 16:15

Oral presentation

By means of laser optical pumping and Larmor-resonance detection, it is possible to use the naturally occurring sodium layer in the mesosphere to measure Earth’s magnetic field magnitude at 90 km above ground. This is an altitude otherwise only accessible by rockets, which only will provide point measurements of very short time scales.

In December 2019, for the first time, we were able to...

145. A saga on the $\gamma$-decay branching ratio of the Hoyle State

16/06/2025, 16:30

Oral presentation

The triple-alpha process is one of the most fundamental processes in stellar nucleosynthesis, particularly the production of $^{12}$C. This process entails the fusion of three helium nuclei to form an intermediate state in $^{12}$C. This intermediate state can decay back into its three constituent alpha particles or radiatively decay to form stable $^{12}$C. At temperatures between 0.1 - 2 GK,...

112. Nuclear excitation functions for natZr(d,x) reactions with focus on the PET/theranostic candidate 86Y

Elise Malmer Martinsen (Univeristy of Oslo)

16/06/2025, 16:45

Oral presentation

Radionuclides are important both for diagnostic and treatment of cancer. 86Y is a candidate for positron emission tomography (PET) and, when employed together with 90Y, is amenable for thernostics. Theranostics can be done using either a self-theranostic nuclide, where the same radionuclide is used in both diagnosis and treatment, or by using two different radionuclides (a theranostic pair),...

148. Charmonium production in heavy-ion collisions with ALICE

16/06/2025, 17:00

Oral presentation

Charmonium production has long been recognized as a key probe for studying the properties of the quark–gluon plasma (QGP). The early formation of heavy-quark pairs, such as $c\bar{c}$ and $b\bar{b}$, makes charmonia ideal tools for investigating the evolution of the hot and dense medium created in ultra-relativistic heavy-ion collisions. At LHC energies, the recombination of uncorrelated...
