Tracing Baryons with eROSITA in Clusters of Galaxies
Esra Bulbul (Max Planck Institute for Extraterrestrial Physics )
See more Hide
Description :
Successfully launched in July 2019, eROSITA, the German-built telescope array operating between 0.2-8 keV on board the Russian-German Spectrum-RG (SRG) mission will deliver the largest catalogs of clusters of galaxies. Clusters of galaxies trace the highest peaks in the cosmic density field and offer an independent and powerful probe of the growth of structure. The final eROSITA All-Sky Survey catalog with more than 100,000 clusters will put us on the verge of a breakthrough in precision cosmological measurements. At the depth of the final All-Sky Survey, the eROSITA Final Equatorial Survey (eFEDS), executed during the Performance Verification phase, has provided a sneak preview of rich cluster science that will be achieved by eROSITA. I will summarise the published eFEDS results and provide the demographics of clusters of galaxies identified in the eROSITA's first All-Sky survey.

L’urgence climatique : le point sur les derniers rapports du GIEC et sur la COP26
Joel Guiot (CEREGE)
See more Hide
Description :

Depuis l’Accord de Paris sur le climat de 2015, différents rapports spéciaux du GIEC ont souligné les impacts du changement climatique et l’importance de le limiter à 1,5°C. Ils ont été complétés par le rapport du réseau MedECC pour la région Méditerranéenne, publié en novembre 2020. Un nouveau rapport du GIEC est paru en août 2021 sur la physique du changement climatique. Il tire à nouveau la sonnette d’alarme et propose des solutions qui malheureusement n’ont été que partiellement prises en compte par nos gouvernements lors de la COP26 à Glasgow en novembre 2021. Deux autres rapports sont parus depuis (en février et mars 2022), l’un sur les impacts du changement climatique et l’autre sur les mesures à prendre pour atténuer ce changement. Les prédictions du GIEC se révèlent à chaque fois très proches de la réalité, et même parfois trop optimistes. Et pourtant nous avons beaucoup de mal à prendre les mesures qui s’imposent. Plus on tarde et plus les changements sociétaux nécessaires devront être radicaux. Dans cette conférence, on présentera les risques liés au changement climatique mais on essaiera également de donner quelques pistes d’adaptation aux changements en cours et d’atténuation des changements futurs.

 

Joël Guiot est directeur de recherche CNRS émérite au laboratoire CEREGE de l’Université Aix-Marseille. Il a reçu la médaille d’argent du CNRS en 2005. Ses principales recherches portent sur l’impact des changements climatiques passés, présents et futurs sur les écosystèmes méditerranéens, en particulier sur la forêt méditerranéenne. En 2012, il a cofondé le laboratoire d’excellence OT-Med pour étudier les risques liés au changement climatique et aux risques naturels dans le bassin méditerranéen. Il a lancé en 2015 avec W. Cramer, le groupe d’experts méditerranéens sur les changements environnementaux et climatiques (MedECC), dont l’objectif est de transférer les connaissances scientifiques sur les changements climatiques aux acteurs de la société des deux côtés de la Méditerranée. Il est co-auteur du rapport spécial du GIEC sur l’impact du réchauffement de la planète à 1,5 ° C publié en octobre 2018.

Unit testing to improve the life of software developers and scientists.
Sébastien Valat (CERN)
See more Hide
Description :

I will present the interest of unit test and TDD (Test Driver Development) as a software development methodology. I will explain the approach from the philosophical side showing that it comes with far more advantages than just validating our code. It goes from improving the code quality to human aspects, like new developer inclusion and keeping the good motivation of the developers. This methodology is a real plus if we consider the increasing performance of computers which tend to translate to increasing expectation from our software and an increasing complexity of the code. I will share my 11 years experience applying this method for my own research projects in the HPC field.

Are pairs of Higgs bosons more interesting than just one ?
Louis D'Eramo (CERN/Northern Illinois University)
See more Hide
Description :
The current description of the electroweak symmetry breaking relies on an Higgs field associated with an additional potential term in the SM Lagrangian. That mechanism is an extraordinary but yet puzzling fundamental piece for explaining the mass of elementary particles. The discovery of the Higgs boson at the LHC was the first milestone to confirm this theory, measuring one of the free parameters introduced. Since then, most of the predicted couplings of this boson to SM particles have been measured, and are in excellent agreement with the theoretical predictions. Nowadays, more attention has been raised on measuring the second free parameter: the Higgs self-interaction. 
In this regard, the Higgs pair production is particularly sensitive to this coupling, while presenting a stimulating challenge due to the limited statistics available. In this talk, I present recent results from the ATLAS collaboration on measurements of HH production as predicted by the Standard Model and its possible enhancement through coupling modification or with the search for beyond-SM physics involving resonances producing HH pairs.

Wellbeing - a forgotten ingredient in academic success
Ewa Pluciennicka (PhDSuccess)
See more Hide
Description :

Mental Health of early career researchers is alarming. Several recent studies reported that PhD candidates are at a high risk of developing mental health disorders such as depression, anxiety, and burn-out. Importantly, Evens (2018) found that PhD students are 6 times more likely to develop mental health disorders in comparison with other highly educated individuals working outside of academia. Finally, Satinsky et al. 2021 showed that despite the growing evidence of mental health dangers for academics, little attention has been given to the ways to improve it and urged for more practical solutions.

In the light of these findings, the aim of this intervention is 1) to raise mental health awareness among academics 2) reduce the risks of developing mental disorders and finally 3) propose a practical solutions on how researchers can take care of their mental health, despite the challenging working environment. In particular, in this 1-hour seminar, studies on mental health and wellbeing in academia will be presented explaining the causes and prevalence of mental distress, followed by practical advice on how to detect and prevent mental health risks at the early stages and how to enhance wellbeing and life satisfaction on a daily basis.

Finally, in line with numerous studies indicating that “happy” employees are more motivated, present better resilience to stress, and are more efficient at work, we believe that improving the mental health of PhD researchers will benefit them individually, but also contribute to creating better working environment and potentially result in better work/research effectiveness for academic institutions.

AMS-02: 10 years of cosmic-rays measurements on the International Space Station
Laurent Derome (LPSC)
See more Hide
Description :
In May 2010, the AMS-02 experiment was installed on the International Space Station. Since then, the experiment continuously detects the cosmic ray particles with energies ranging from sub-GeV to several TeV. The AMS-02 detectors allow to measure the components of the cosmic rays, electrons/positrons, protons, antiprotons and all the nuclei from helium to iron with an unprecedent precision.
In this presentation, I will present the AMS-02 project, the instrumentation implemented to identify and measure the energy of cosmic ray particles as well as the main results from the experiment. In particular, I will present the measurement of positrons and antiprotons and discuss the interpretation of these measurements in the framework of dark matter searches and the measurement of galactic cosmic ray nuclei which allows the study of the sources and the propagation of cosmic rays.
