| Session | 3. Pulsar winds nebulae (including Crab flares) |
| 1st Abstract | Pulsar Wind Nebulae (PWNe), the inflated bubbles of relativistic particles and magnetic fields injected by neutron stars, provide unique laboratories for probing Nature’s most powerful accelerators and the interaction of their winds with the surrounding SN ejecta or ISM. PWNe have become an important legacy of the Chandra X-ray Observatory and currently represent the largest population of identified Galactic very high-energy gamma-ray sources. I will review the growing X-ray and gamma-ray observations of these fascinating objects which, together with radio observations, allow us to infer the physical properties of these systems. I will focus on the PWN diversity among the SNR population, in connection with their debated SN progenitors and environment. |

| Session (2nd abstract) | 4. Magnetic fields in SNRs and PWNe |
| 2nd Abstract | The characteristic ages of neutron stars are often inconsistent with their hosting supernova remnant (SNR) ages. We address this discrepancy by studying a sample of pulsars, including those with extreme magnetic fields (such as magnetars and the Central Compact Objects), securely associated with SNRs. We discuss the implications of our study to magnetic field evolution in neutron stars and their distinct energy loss mechanisms. |
