Every 10 years, X-ray astronomers gather in Bologna, Italy, to review the state of the field. After 30 years of these meetings, is there really still a separate field of X-ray astronomy?
Seventy years after the first detection of interstellar magnetic fields, experts met in Newcastle upon Tyne, UK, on 10–14 June 2019, to discuss new perspectives on interstellar magnetic fields from small to large scales, from the Milky Way to distant galaxies and from observations to theories and simulations.
A Kavli Institute for Theoretical Physics workshop in July 2019 directed attention to the Hubble constant discrepancy. New results showed that it does not appear to depend on the use of any one method, team or source. Proposed solutions focused on the pre-recombination era.
To what extent do small-scale processes, such as star formation and black-hole accretion, affect global galaxy properties such as stellar masses, star formation rates and chemical abundances?
The European Astronomical Society awarded its most prestigious prizes during its annual meeting, the European Week of Astronomy and Space Science, held in Lyon, France, from 24 to 28 June 2019.
Held in Bologna, Italy, in May 2019, the conference served to engage a wide community in the planning for this first open observatory in very-high-energy gamma rays, expected to start full operation in 2025.
