FRANCI 2023 will take place in Würzburg on 13 October 2023 and is free of charge.
The first presentations will start at 10 am, please arrive a bit in advance so that we don't catch delays in starting the event.
Looking forward to seeing lots of you in Würzburg,
The FRANCI committee!
Registration on the 1st floor of the venue

Relativistic jets are among the most powerful phenomena in the Universe. They are launched from rotating supermassive black holes and propagate collimated over thousands of light years while accelerating particles to the highest energies. In order to shield light on the formation, propagation and emission processes of relativistic jets we perform general and special relativistic magneto-hydrodynamical (G[S]RMHD) simulations taking into account radiation microphysics as well as emission processes across the electromagnetic spectrum. In the talk we will provide current updates on the numerical methods and their applications to observations.
Very long baseline interferometry (VLBI) observations enable us to study the parsec-scale structure of active galactic nuclei (AGN), and connect changes in jet brightness and morphology to the multiwavelength variability exhibited by these sources. In this talk, I will focus on our work related to the investigation of the connection between the radio and gamma-ray variability. I will discuss our VLBI studies of a gamma-ray flaring blazar from the early Universe, as well as AGN monitoring programmes aimed at studying high-energy detected sources and strong neutrino associations.
Intensity interferometry is a technique similar to conventional amplitude interferometry, except that it is insensitive
to atmospheric turbulence and that it does not require good optical quality of the telescope system. Therefore arrays of Imaging Atmospheric Cherenkov Telescopes can be (and since a few years are) used to measure the angular sizes of stars and star systems. We report from the first two Intensity Interferometry campaigns at the H.E.S.S. gamma ray observatory in 2022 and 2023.
Soft gamma-ray observations are key to understanding the astrophysics of high-energy phenomena including accreting black holes, stellar flares, matter-antimatter annihilations, cosmic rays, and dark matter, among others. In this talk, I will give an overview on how these measurements are performed, the next generation MeV telescope, COSI, and projects in my group related to nucleosynthesis, the cosmic gamma-ray background, and ideas to overcome the MeV sensitivity gap with new instruments concepts.
