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…
Multi-wavelength observations of the lensed quasar PKS 1830211 during the 2019 -ray flare
S. Vercellone, I. Donnarumma, C. Pittori +32
PKS 1830211 is a -ray emitting, high-redshift (z ), lensed flat-spectrum radio quasar. During the period mid-February to mid-April 2019, this source underw…
Tracking the X-ray Polarization of the Black Hole Transient Swift J1727.8-1613 during a State Transition
Adam Ingram, Niek Bollemeijer, Alexandra Veledina +120
We report on an observational campaign on the bright black hole X-ray binary Swift J1727.81613 centered around five observations by the Imaging X-ray Polarimetry Explorer (IXPE)…
Discovery of X-ray Polarization from the Black Hole Transient Swift J1727.8-1613
Alexandra Veledina, Fabio Muleri, Michal Dovciak +113
We report the first detection of the X-ray polarization of the bright transient Swift J1727.8-1613 with the Imaging X-ray Polarimetry Explorer. The observation was performed at the…
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…
Single-dish and VLBI observations of Cygnus X-3 during the 2016 giant flare episode
E. Egron, A. Pellizzoni, M. Giroletti +34
In September 2016, the microquasar Cygnus X-3 underwent a giant radio flare, which was monitored for 6 days with the Medicina Radio Astronomical Station and the Sardinia Radio Tele…
Imaging of SNR IC443 and W44 with the Sardinia Radio Telescope at 1.5 GHz and 7 GHz
E. Egron, A. Pellizzoni, M. N. Iacolina +33
Observations of supernova remnants (SNRs) are a powerful tool for investigating the later stages of stellar evolution, the properties of the ambient interstellar medium, and the ph…
Observations of Supernova Remnants with the Sardinia Radio Telescope
E. Egron, A. Pellizzoni, S. Loru +11
In the frame of the Astronomical Validation activities for the 64m Sardinia Radio Telescope, we performed 5-22 GHz imaging observations of the complex-morphology supernova remnants…
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…
