From January 14 to 17, 2019 we offered a series of DDAp lectures on Exploring the inflation era with CMB Polarization with our guest scientist Dr. Jean-Christophe Hamilton (Astroparticule et Cosmologie - IN2P3 - CNRS, Université Paris).

The lectures were part of the Double Doctoral degree in Astrophysics (DDAp) between KIT and UNSAM.

Abstract:

The CMB radiation is an amazing observable that nature offered to cosmologists throughout the Universe. Observed from here and now, its temperature and polarization anisotropies reveal the geometry of the Universe through which the radiation has travelled for 13.6 billion years and therefore allows to put tight constraints on cosmological parameters. Furthermore, specific features in the temperature and even more in the polarisation patterns are directly related to events that happened in the very primordial Universe.

Specifically, polarization B-modes are expected to be produced by primordial gravitational waves, themselves predicted by the inflationary theory. Their detection would not only strongly support inflation as the origin of the fluctuations in the Universe, but also allow to understand the physics of the inflation era.

In order to observe these B-modes a lot of experimental efforts are ongoing throughout the world with various instrumental designs optimized for various important observational aspects. The main challenges to be addressed in order to detect these B-modes are the weakness of the signal itself, the instrumental and analysis systematic effects that may bias the polarization measurement and induce a mixing between the strong E and the weak B-modes and of course the presence of strong polarized foregrounds such as dust polarized emission and lensing-induced B-mode signal.

On 20 November 2018, the inauguration of the Helmholtz International Research School for Astroparticle Physics and Enabling Technologies (HIRSAP) took place at the Universidad Nacional de San Martín (UNSAM) in Buenos Aires. At Campus Miguelete, guests and representatives of the two participating universities UNSAM and KIT came together to officially start off the graduate school in a festive event.

From Germany Dr. Ilja Bohnet (Research Fellow Matter of the Helmholtz Association), Prof. Thomas Hirth (Vice President for Innovation and International Affairs at KIT), Prof. Johannes Blümer (Head of Division 5 at KIT), Prof. Ralph Engel (Spokesperson of HIRSAP at KIT), and scientists from KIT participated in the event.

From Argentina the participants were Jorge Tezón (Manager of Scientific and Technological Development at CONICET), Prof. Carlos Greco (Rector of UNSAM), Prof. Alberto Carlos Frasch (Vice Rector of UNSAM), Prof. Alberto Etchegoyen (Spokesperson of HIRSAP at UNSAM/ITeDA) and scientists from UNSAM.

The first PhD students of the school were also on site to present themselves and their research topics in a PhD workshop. In this way, all participants were given the opportunity to gain an overview of the diversity and complementarity of the topics of the doctoral theses and to get to know the doctoral students better.

On the German side, the opening ceremony of the HIRSAP already took place in April 2018 at KIT.

On April 17, 2018 the first kick-off event for the Helmholtz International Research School for Astroparticle Physics and Enabling Technologies (HIRSAP) of the Karlsruhe Institute of Technology (KIT) and the Universidad Nacional de San Martín (UNSAM) in Buenos Aires (Argentina) took place at KIT.

It started with welcome talks by KIT Vice President Research Prof. Oliver Kraft and by UNSAM Vice Rector Prof. Alberto Carlos Frasch followed by introductory talks by the KIT head of division 5, Prof. Johannes Blümer, by Spokesperson of HIRSAP at KIT Prof. Ralph Engel, and by Spokesperson of HIRSAP at UNSAM/ITeDA Prof. Alberto Etchegoyen from Argentina. Two PhD students of the existing program Double Doctoral degree in Astrophysics (DDAp), Isabel Astrid Goos (CNEA/IB, Bariloche), and David Schmidt (KIT), presented some special insights in their impressions and experiences in the cotutelle program. Finally the keynote speaker Dr. Walter Winter from DESY gave a very interesting talk on “Multi-Messenger Astroparticle Physics”.

From November 2 – 10, 2017 we offered a KSETA course with our guest scientists Prof. Dr. Ricardo Piegaia and Dr. Dario Rodrigues from CONICET/UBA/UNSAM in Buenos Aires (Argentina).

Thes course offered a practical approach to those principles and practices of statistics that are most relevant for data analysis in particle and astroparticle physics. The lectures covered parameter estimation, confidence intervals and limits, profile likelihoods, statistical tests for goodness-of-fit, application of hypothesis testing to searches for new phenomena, treatment of systematic uncertainties, and a critical discussion and comparison between the frequentist and the Bayesian approaches to these subjects. Throughout, real-world examples were used to illustrate the practical application of the ideas.

Each session consisted of a 1-hour lecture followed by one hour of practical computing, with exercises based on that day's lecture. In order to follow the hands-on sessions, participants needed to bring their own laptops and have a basic prior knowledge of ROOT and C++. No previous experience with more recent ROOT-based statistics tools like RooFit and RooStats was assumed.

This course was part of the Double Doctoral Degree in Astrophysics between UNSAM and KIT.

Dr. Silvia Mollerach (CONICET, Centro Atómico Bariloche, and Universidad Nacional de San Martín, UNSAM, Argentina)  gave a KSETA Seminar on Statistical Methods for Astroparticle Physics from September 26 - 30, 2016.

The course covered different statistical methods used to analyse data in astroparticle physics, including the simulation and comparison of measurements to theoretical models.

Some basic statistical topics like the concept of probabilities, probability distributions, the calculation of expectation values and higher moments, and the determination of uncertainties as well as correlations were reviewed.

More advanced topics relevant to data analyses and statistical inference were discussed. Among these were fitting appropriate models to data, estimating the goodness of fit, testing hypotheses and the construction of confidence intervals. This also included a discussion of the look-elsewhere-effect and the cosmic variance.

To better explore these topics, the study of anisotropies in the cosmic rays distribution was used as examples, including large scale anisotropies, clustering studies, and correlation with possible source populations.

This seminar was part of the KSETA Topical Courses as well as of the Double Doctoral Degree in Astrophysics between UNSAM and KIT.
