77. Experiment design for 21st Century astronomy

Emille Eugenia DE OLIVEIRA ISHIDA (CNRS)

Astrophysics and Cosmology

Talk

The recent increase in volume and complexity of astronomical data has fomented the use of machine learning techniques. However, the acquisition of labels in astronomy is, by construction, very expensive and time-consuming. In this context, experiment design tasks are aimed at optimizing the allocation of scarce labelling resources. The proper application of such methods will be crucial to...

50. Dark Matter direct detection experiments

Astrophysics and Cosmology

Talk

Dark matter particles pervading our galactic halo could be directly detected by measuring their scattering off target nuclei or electrons in a suitable detector. The expected signal from this interaction is rare, demanding ultra-low background conditions, and small energy deposits below tens of keV would be produced, requiring low energy detection thresholds. Many different and complementary...

40. Towards an End-to-End Optimization of IceCube-Gen2 Neutrino Observatory

Christian Glaser

Astrophysics and Cosmology

Talk

I will present the status of optimizing the radio detector of the planned IceCube-Gen2 neutrino observatory at the South Pole. IceCube-Gen2 will enable neutrino astronomy at ultra-high energies (UHE) and will provide insights into the inner processes of the most violent phenomena in our universe. Detecting these UHE neutrinos would be one of the most important discoveries in astroparticle...

78. Challenges in Cosmic Microwave Background Data Analysis

Dr Belèn Barreiro (IFCA/CSIC)

Astrophysics and Cosmology

Talk

The Cosmic Microwave Background (CMB) is a radiation that reaches us from all the directions of the sky. It originated shortly after the Big Bang and is the oldest radiation that we can observe in the Universe, providing us with very valuable information about the early universe and how it evolved. CMB radiation is also polarized. In particular, the next big challenge in the CMB field is to...

57. Optimization of the Future P-ONE Neutrino Telescope

Dr Christian Haack (Technical University of Munich)

14/09/2022, 09:00

Astrophysics and Cosmology

Talk

P-ONE is a planned cubic-kilometer-scale neutrino detector in the Pacific ocean. Similar to the successful IceCube Neutrino Observatory, P-ONE will measure high-energy astrophysical neutrinos to help characterize the nature of astrophysical accelerators. Using existing deep-sea infrastructure provided by Ocean Networks Canada (ONC), P-ONE will instrument the ocean with optical modules - which...

70. The Einstein Telescope project

Giacomo Bruno (Universite Catholique de Louvain (UCL) (BE))

Astrophysics and Cosmology

Talk

The Einstein Telescope (ET) is the future European terrestrial gravitational wave observatory based on laser interferometry. The project is currently in the preparatory phase after its integration in the EU ESFRI roadmap for large research infrastructures in 2021 and the official creation of the scientific Collaboration in 2022. A number of key design innovations are foreseen for ET like...

49. Normalizing flows for differentiable expectation values

Thorsten Glüsenkamp (Universität Erlangen-Nürnberg)

14/09/2022, 09:50

Astrophysics and Cosmology

Talk

I will give a short introduction to (conditional) normalizing flows and discuss why they are essential to calculate "manageable" differentiable expectation values of continuous random variables. I will discuss some examples where this might be useful and end the talk with a github-package that combines some state of the art conditional normalizing flows to be used with minimal manual labor.

60. Muon identification and gamma/hadron discrimination using compact single-layered water Cherenkov detectors powered by Machine Learning techniques

Astrophysics and Cosmology

Talk

The muon tagging is an essential tool to distinguish between gamma and hadron-induced showers in wide field-of-view gamma-ray observatories. In this work, it is shown that an efficient muon tagging (and counting) can be achieved using a water Cherenkov detector with a reduced water volume and multiple PMTs, provided that the PMT signal spatial and time patterns are interpreted by an analysis...
