JUNO: the first multi-kton liquid scintillator based neutrino detector

The Jiangmen Underground Neutrino Observatory (JUNO) is a neutrino experiment under construction near Jiangmen, China. Its main component  will be a spherical 20 kton liquid scintillator detector placed in a 700 m deep underground laboratory. The experiment is designed for the determination of the neutrino mass hierarchy by measuring oscillation effects of neutrinos from two nuclear power plants at 53 km baseline. In addition to that, JUNO has the potential to increase the precision of already measured oscillation parameters and it can give a major contribution in the field of geoneutrinos. Astrophysical measurements of solar, supernova, atmospheric and potentially of DSNB neutrinos are also part of the physics programme. The seminar will review the physics goals, design, as well as the status of the JUNO project.

The H.E.S.S. Galactic Plane Survey

H.E.S.S. (High Energy Stereoscopic System) is a hybrid array of five Imaging Atmospheric Cherenkov Telescopes observing the very high energy gamma-ray sky. In the past decade, this experiment has significantly contributed to the field of ground-based gamma-ray astronomy. In particular, the H.E.S.S. Galactic plane survey (HGPS), conducted from 2004 to 2013, was the first high-resolution (~0.1 deg) and sensitive (~1.5% Crab Nebula point-source sensitivity) survey of the Milky Way in TeV gamma-rays. Comprising ~2800-hrs of observation time, it revealed the existence of a diverse population of cosmic accelerators in the Galaxy. In this talk I will present an overview of the results from this decade-long H.E.S.S. survey program.

A Brief History of Fast Radio Bursts

Fast radio bursts are millisecond-duration radio beacons from a so-far unidentified class of extragalactic sources first discovered about a decade ago. Their inferred distances, and therefore radio burst energies, challenge models based on known source classes, while their inferred rates suggest they are fairly common. While most sources have so-far been observed as one off events, the recent localization of the sole repeating FRB to a low metallicity dwarf galaxy has provided key insights into this population. Several new telescopes coming online in the next year predict a flood of new detections, providing relief to a detection-starved field.
