Broadband radio study of the supernova remnant Kes 73

S. Loru, A. Ingallinera, A. Pellizzoni +16

Strong shocks occurring in supernova remnants (SNRs), and their interaction with an often anisotropic surrounding medium, make SNRs ideal laboratories for studying the production a…

Recovery of the X-ray polarisation of Swift J1727.81613 after the soft-to-hard spectral transition

J. Podgorný, J. Svoboda, M. Dovčiak +34

We report on the detection of X-ray polarisation in the black-hole X-ray binary Swift J1727.81613 during its dim hard spectral state by the Imaging X-ray Polarimetry Explorer (I…

New high-frequency radio observations of the Cygnus Loop supernova remnant with the Italian radio telescopes

S. Loru, A. Pellizzoni, E. Egron +19

Supernova remnants (SNRs) represent a powerful laboratory to study the Cosmic-Ray acceleration processes at the shocks, and their relation to the properties of the circumstellar me…

Investigating the high-frequency spectral features of SNRs Tycho, W44 and IC443 with the Sardinia Radio Telescope

S. Loru, A. Pellizzoni, E. Egron +20

The main characteristics in the radio continuum spectra of Supernova Remnants (SNRs) result from simple synchrotron emission. In addition, electron acceleration mechanisms can shap…

Long Term Study of the Double Pulsar J0737-3039 with XMM-Newton: pulsar timing

M. N. Iacolina, A. Pellizzoni, E. Egron +8

The relativistic double neutron star binary PSR J0737-3039 shows clear evidence of orbital phase-dependent wind-companion interaction, both in radio and X-rays. In this paper we pr…

Search for pulsations at high radio frequencies from accreting millisecond X-ray pulsars in quiescence

M. N. Iacolina, M. Burgay, L. Burderi +2

It is commonly believed that millisecond radio pulsars have been spun up by transfer of matter and angular momentum from a low-mass companion during an X-ray active mass transfer p…

Searching for pulsed emission from XTE J0929-314 at high radio frequencies

M. N. Iacolina, M. Burgay, L. Burderi +2

The aim of this work is to search for radio signals in the quiescent phase of accreting millisecond X-ray pulsars, in this way giving an ultimate proof of the recycling model, ther…
