12. The Crab Pulsar's Very High Energy emission: Insights from GeV to TeV Energies

The Crab Pulsar is one of the few pulsars detected from GeV up to TeV energies. This talk will review recent gamma-ray observations of the pulsar performed with Imaging Atmospheric Cherenkov Telescopes (IACTs) and analyze their implications for current theoretical models that aim to explain the Very High Energy (VHE) emission from this source.

13. Geminga: the first discovered VHE middle-aged pulsar

The detection of Very-High-Energy emission from pulsars is one of the milestone results in the field. Among the few sources know to date, Geminga is the only one with an age of a few hundred kilo-years. From its discovery to the recent observations with Cherenkov Telescopes, Geminga never ceases to surprise us.

15. Testing for a "Crab-like" Emission Tail above 10 GeV from the Vela Pulsar and PSR B1706-44 using combined H.E.S.S. & Fermi-LAT data

Measuring pulsar spectra in the tens of GeV range is crucial for constraining high-energy emission models, but this effort is hindered by limited Fermi-LAT statistics and the sensitivity constraints of ground-based telescopes. In this study, we analyze data from the largest H.E.S.S. telescope (CT-5) and Fermi-LAT to measure the spectra of the Vela pulsar and PSR B1706-44 in the 1–100 GeV...

17. The many facets of transitional millisecond pulsars: can accretion- and rotation-powered states coexist?

Giulia Illiano

The increasingly thrilling investigation of millisecond pulsars has recently overturned a long-standing paradigm. Traditionally, these pulsars were thought to shine as rotation-powered radio and/or gamma-ray sources only after a Gyr-long, X-ray bright phase fueled by the accretion of matter from a low-mass donor star. However, transitional millisecond pulsars challenge this classification by...
