  47. 50. Centaurus A: Jet Chemical Enrichment and Ultra-High-Energy Cosmic-Ray Production
    Ana Laura Müller (FZU - Institute of Physics of the Czech Academy of Sciences)

    Relativistic jets from active galactic nuclei are powerful sites for accelerating ultra-high-energy cosmic rays (UHECRs), but their predominantly leptonic composition raises the question of how heavy nuclei are injected into the flow. We investigate Wolf-Rayet (WR) stellar winds as a natural source of mass loading and chemical enrichment in radio galaxy jets. Jet–wind interactions produce...

  48. 52. Constraints on modified gravity using gravitational waves
    Pawan Kumar Gupta (CAMK, Warsaw, Poland)

    Modified theories of gravity provide a promising framework for testing General Relativity in the strong-field regime. Among them, massive scalar-tensor theories predict finite-range scalar interactions that modify the dynamics and gravitational-wave emission of compact binaries. In this talk, I will present an effective field theory description of massive scalar-tensor gravity and its...

  51. 51. Microquasars observed in the γ-ray band :the parsec-scale outer jets of SS 433
    Michelle Tsirou (Institute of Physics of the Czech Academy of Sciences (FZU))

    The galactic microquasar SS 433 has been extensively studied across the years, as it presents a unique opportunity to understand jet dynamics thanks to its proximity to Earth, at an estimated distance of ~ 5.5 kpc. The HAWC observatory in 2018 purported very-high-energy (VHE) emission associated to the SS 433 system, indicating that the energetic particles producing the X-ray emission of the...
