    Galaxies within galaxies in the TIMER survey: stellar populations of inner bars are scaled replicas of main bars
    Inner bars are frequent structures in the local Universe and thought to substantially influence the nuclear regions of disc galaxies. In this study we explore...

    Gamma-ray flaring activity of NGC1275 in 2016-2017 measured by MAGIC
    We report on the detection of flaring activity from the Fanaroff-Riley I radio galaxy NGC 1275 in very-high-energy (VHE, E > 100 GeV) gamma rays with the Major...

    Gamma-ray line emission from OB associations and young open clusters. I. Evolutionary synthesis models
    We have developed a new diagnostic tool for the study of gamma-ray emission lines from radioactive isotopes (such as 26Al and 60Fe) in conjunction with other...

    Gamma-ray line emission from OB associations and young open clusters. II. The Cygnus region
    Gamma-ray and microwave observations of the Cygnus region reveal an intense signal of 1.809 Me line emission, attributed to radioactive decay of 26, that is...
