Serena_Giardino_Physikerin.jpg
Serena is a final-year PhD student at the Max Planck Institute for Gravitational Physics and the University of Heidelberg, in the group of Prof. Lavinia Heisenberg. Her research focuses on understanding the true nature of gravity. She explores modified theories of gravity that might explain the accelerated expansion of the universe without resorting to the mysterious dark energy and works on figuring out what the cosmological implications of going beyond Einstein's General Relativity are for both the early and the late universe. Specifically, she works on a novel description unifying different gravity theories based on thermodynamics and on constructing alternatives to the Big Bang model, such as cosmological bounces, that solve some of the puzzles of standard cosmology.
She enjoys bringing science to the public in several languages and is active in her institute's Equal Opportunity Office.

M.Sc. Chloé Gaudu (Wuppertal) - Kalenderwoche 8

Chloé is a Ph.D. student in the Astroparticle physics group at the University of Wuppertal, working with hadronic interaction models to solve the “Muon Puzzle.”

Established state-of-the-art models, including EPOS-LHC, Sibyll 2.3d, and QGSJet-II.04, are utilized by astroparticle physicists to describe the hadronic interactions within extensive air showers (EAS) resulting from cosmic ray interactions with Earth's atmosphere. Though developed by separate teams with differing initial assumptions, these models converge on the following consensus: air shower simulations exhibit a muon deficit compared to experimental measurements of the Pierre Auger Observatory — referred to as the “Muon Puzzle.” To solve this puzzle, Chloé works with the Angantyr model of Pythia 8, yet another hadronic interaction model tailored for Large Hadron Collider experiments. Angantyr introduced new features aimed at enhancing descriptions of hadron-nucleus interactions, thus motivating its potential application in air shower studies. The evaluation and validation of this model are done using the analysis framework Rivet, which requires specific plug-ins, of which Chloé has written several for each experimental dataset chosen as a reference. The next steps for her work would be to create a tuned version of Pythia 8 by adjusting parameter values, shifting the physics of Pythia to better describe hadron productions in pion-proton and pion-carbon interactions while keeping intact the knowledge they have gathered so far from proton-proton interactions. This tuned Pythia 8 would be used in codes, like Corsika 8 or MCEq, to probe astroparticle observables, allowing comparison with experimental datasets and previous simulations with the aim of a more accurate description of muon production in EAS.

One should keep in mind that this tuning endeavor is a multi-dimensional task demanding various expertise in the fields of astroparticle and particle physics, from the experimental datasets, model parameters, and observable weight selection for meaningful interpretation, needing a close collaboration between working groups.

Francesca_Calegari_Physikerin.jpg

Francesca leads the Attosecond Science group at the Center for Free-Electron Laser Science at DESY in Hamburg and is a full professor of physics at Hamburg University. She is also the head of the scientific board of PIER, the strategic partnership between DESY and Hamburg University, and one of the speakers of the Cluster of Excellence “Advanced Imaging of Matter.” Amongst other distinctions, she is an ERC StG laureate, received the ICO prize and the Ernst Abbe medal from the International Commission of Optics, and is an Optica Fellow.

The main focus of her research is to track and ideally control in real time the electron dynamics occurring in systems with increasing complexity, from simple molecules to molecules of biological interest and nanostructured materials. To this purpose, her group develops state-of-the-art table-top light sources providing extreme time resolution (from a few femtoseconds down to attoseconds) and spanning from the infrared to the ultraviolet and then further down in wavelengths to the soft-x ray spectral range. In her group, attosecond technology is used to understand the role of electron dynamics in the photo-induced chemical changes that occur in our own biomolecules (e.g., DNA and proteins) in a bottom-up approach. Her research aims to control molecules' chemical reactivity at the electron time scale (attochemistry) to achieve efficient light harvesting. Her approach is fully synergetic, with the possibility to resolve structural changes in molecules through femtosecond time-resolved X-ray diffraction using XUV/X-ray Free Electron Lasers (FELs).

Francesca is active in promoting diversity in science. She has been the Equal Opportunity director for the cluster of excellence AIM and is mentoring female scientists via the DynaMENT mentoring program in Hamburg.

Stefanie_Todt_Physikerin.JPG

Stefanie is a particle physicist at the Dresden University of Technology (TUD) and part of the ATLAS experiment at the LHC at CERN.

Her research focuses on scattering processes among electroweak gauge bosons. Including triple and quartic electroweak self-coupling interactions as well as the exchange of a Higgs boson, these scattering processes are an excellent tool for studying the delicate interplay of the gauge structure and the electroweak symmetry-breaking mechanism of the Standard Model (SM).

Her research projects examine the scattering of two same-charge W± bosons and contributed to the first observation of a process containing vector boson scattering with data from the ATLAS experiment at the LHC.

Furthermore, she studies the effects of an effective field theory (EFT) model describing beyond SM extensions that generate anomalous quartic gauge couplings in the electroweak sector.

For over 10 years, she has been active in outreach, mentoring, and supervision. As a mediator for particle physics, she participates in national and international masterclasses for high school students organized by the Netzwerk Teilchenwelt. She likes presenting and discussing her research field in public, at events such as Science in Pubs or the 35c3.

Standing for a supportive and appreciative scientific community, she has been the spokesperson for the German Ph.D. and young scientists representatives in the ATLAS experiment.
