Descripción

The supernova remnant (SNR) W44, one of the first sources firmly established as a hadronic accelerator in the GeV regime, has been observed for over 200 hours with the H.E.S.S. telescope array. We present the results of a deep analysis of this dataset, revealing new insights into the gamma-ray emission from W44 and its interaction with the surrounding interstellar medium. In particular, we discuss the implications of W44's contribution to the local cosmic-ray population and its role in shaping the observed gamma-ray morphology. These results will be put in the context of theories of particle acceleration and escape processes in middle-aged SNRs.
