Invited Talk

The Imaging X-ray Polarimetry Explorer (IXPE) is a joint NASA-ASI mission, launched on the 9th of December 2021 and entirely devoted to measuring the polarization of cosmic X-ray sources. Thanks to the innovative gas detectors positioned in the focal plane of its three, identical, X-ray telescopes, IXPE possesses the unprecedented capability of performing space, time and energy resolved...

Contributed Talk

Current wisdom accounts the diversity of neutron star observational manifestations to their birth scenarios influencing their thermal and magnetic field evolution. Among the kind of observed neutron stars, radio pulsars represent by far the largest population of neutron stars.

In our work we aim at constraining the observed population of canonical neutron star period, magnetic field and...

92. Interpreting the high-energy sub-exponentially cutoff spectral shape of the Vela pulsar

Contributed Talk

The Fermi Large Area Telescope (LAT) has detected over 270 pulsars in the GeV range. Their spectra are typically fit with hard power law functions with sub-exponential spectral cutoffs occurring in a narrow band around a few GeV. Recently, a debate ignited over the GeV emission mechanism. Traditionally, this component has been attributed to curvature radiation from the inner magnetosphere; in...

144. Searching for Gravitational Waves with Gamma Rays

Invited Talk

Pulsar timing arrays (PTAs) are long-term monitoring campaigns of many millisecond pulsars (MSPs). Their key science goal is the detection and characterization of the few-nHz gravitational wave background (GWB) expected primarily from the mergers of supermassive black holes. These waves are random (stochastic), but the shared vantage point of the earth introduces hallmark correlations in the...
