Multi-wavelength emission in resistive pulsar magnetospheres

Jérôme Pétri

In this paper, we compute a full set of neutron star magnetosphere structures from the basic vacuum regime to the dissipation-less force-free regime by implementing a resistive pre…

GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-Spin Black Hole Coalescence

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1783

We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW…

Harnessing the XMM-Newton data: X-ray spectral modelling of 4XMM-DR11 detections and 4XMM-DR11s sources

A. Viitanen, G. Mountrichas, H. Stiele +13

The XMM-Newton X-ray observatory has played a prominent role in astrophysics, conducting precise and thorough observations of the X-ray sky for the past two decades. The most recen…

Rapidly rotating hot nuclear and hypernuclear compact stars: integral parameters and universal relations

Stefanos Tsiopelas, Armen Sedrakian, Micaela Oertel

In this work, we investigate hot, isentropic compact stars in the limiting cases of static and maximally rotating configurations, focusing on how variations in the symmetry energy…

Born to be recycled: a comprehensive population synthesis of the Galactic millisecond pulsars

Mattéo Sautron, Jérôme Pétri, Dipanjan Mitra +2

Millisecond pulsars (MSPs) are the oldest but fastest pulsars known to date. In the 1980s, to explain how these pulsars could be formed, a new hypothesis was formulated: the recycl…

Unveiling blazar synchrotron emission: a multiwavelength polarimetric study of HSP and LSP populations

Sara Capecchiacci, Ioannis Liodakis, Riccardo Middei +96

Polarimetric properties of blazars allow us to put constraints on the acceleration mechanisms that fuel their powerful jets. By studying the multiwavelength polarimetric behaviour…
