10:15-10:30 | 15 | A tale of two experiments and the not-so-straight journey of scientific endeavour | Laura Manenti | “It was the best of times, it was the worst of times…” Dickens’ words well describe the reality of experimental physics, where success and failure often go hand in hand. In this talk, I will take you through the development and characterisation of one of the world's quietest sensors: a superconducting transition-edge sensor designed for a future dark matter experiment searching for dark photons. I will tell you about the path that led to the final experiment and its outcome, sharing the challenges encountered along the way and the behind-the-scenes moments not shared in the final published paper. Through this tale, I will show that in experimental physics, the norm is that things do not unfold as planned. Yet, it is precisely this unpredictability that makes the journey so exciting. | |

11:00-11:30 | 30 | Keynote presentation - Dark Matter Direct Detection | Luca Scotto Lavina | ||
11:30-11:45 | 15 | Dark Sector Searches at Belle/Belle II Experiment | Eiasha Waheed | The Belle and Belle II experiments are crucial for exploring the dark sector by searching for axion-like particles (ALPs) and heavy neutrinos, which may extend beyond the Standard Model. These searches focus on ALPs as potential dark matter candidates and study their decays, while also probing heavy neutrinos in B meson decays. With unprecedented sensitivity, Belle II pushes the boundaries on current dark matter and new physics searches, setting stringent limits on ALP couplings and neutrino properties. | |

15:30-15:45 | 15 | Galaxy clusters: giant dark matter particle colliders | Ellen Sirks | Galaxy clusters are the largest gravitationally bound structures in the Universe. Because of their high density and local velocity dispersion, they are ideal environments for probing the nature of dark matter. The specific properties of dark matter can have great effects on both clusters as a whole as well as on the galaxies residing in them. In this seminar I will present my work studying some of the effects of self-interacting dark matter on simulated galaxy clusters. In addition, I will discuss how I will be studying these effects observationally using the balloon-borne SuperBIT telescope. | |
15:45-16:00 | 15 | Development of Mass Spectrometry Techniques for Low Background Experiments | Dominik Koll | Mass spectrometry is the method of choice to determine radionuclide concentrations in detector materials for low background experiments if decay counting is not applicable. In this presentation, recent work to develop and optimise mass spectrometric techniques for the determination of radionuclides such as 40K, 129I, 210Pb or actindes will be discussed with focus on the future capabilities of the new Helmholtz Accelerator Mass Spectrometer Tracing Environmental Radionuclides (HAMSTER) facility. | |
16:00-16:15 | 15 | Mental well-being in gravitational wave and high energy physics | Kamiel Janssens | Many people in academia struggle with their mental well-being due to the unique environment and conditions. However, at the same time many researchers love their fulfilling job. In a recent set of survey(s) we probed the general mental well-being of researchers in the field of gravitational waves (2021) and the wider High Energy/Astrophysics community (2022). We start by highlighting some of the key conclusions of these surveys. Is there any difference between the subsequent years? How resilient is the mental well-being of our collaborators? Tune in to learn about these and many other related topics! | |
16:15-16:30 | 15 | Near-quantum limited axion dark matter search with the ORGAN experiment around 26 micro-eV | Graeme Flower | The latest iteration of the ORGAN experiment operated at millikelvin temperatures using a flux-driven Josephson parametric amplifier (JPA) for reduced noise, along with various other upgrades over previous iterations. Covering the 25.45−26.27 micro-eV mass range, this near-quantum limited phase of ORGAN employs a conducting rod resonator and a 7-T solenoidal magnet to place the most sensitive exclusion limits on axion-photon coupling in the range to date. | |
