A0538-66: A transient ultraluminous X-ray source with a relativistic outflow, 69ms pulsations, and anomalous optical activity
Lorenzo Ducci, Sandro Mereghetti, Ciro Pinto +8
A0538-66 is a peculiar Be/X-ray binary in the Large Magellanic Cloud, hosting the fastest spinning neutron star of its class (~69ms) and showing the brightest optical bursts of any…
A new Chandra look at the globular cluster NGC 6540 and its peculiar X-ray flaring source
A. Sacchi, S. Mereghetti, R. Di Stefano +4
We report the results of a deep ( ks) Chandra exposure of the globular cluster NGC 6540, obtained by combining three observations carried out in 2023-2024 to investigate…
The long quest for vacuum birefringence in magnetars: 1E 1547.0-5408 and the elusive smoking gun
Roberto Taverna, Roberto Turolla, Lorenzo Marra +7
Magnetars are now known to be among the most strongly polarized celestial sources in X-rays. Here we report on the observation of the magnetar 1E 1547.0-5408 per…
Multi-wavelength study of the high Galactic latitude supernova remnant candidate G118.4+37.0 associated with the Calvera pulsar
Emanuele Greco, Michela Rigoselli, Sandro Mereghetti +4
The candidate supernova remnant (SNR) G118.4+37.0 (Calvera's SNR), discovered as a faint radio ring at high Galactic latitude and coincident with extended Fermi/LAT gamma-ray emiss…
X-ray emission from isolated neutron stars: latest results from XMM-Newton, NICER and eROSITA
Michela Rigoselli
The X-ray spectra of isolated neutron stars (INSs) typically include a thermal component, that comes from the cooling surface, and a non-thermal component, produced by highly-relat…
IXPE detection of highly polarized X-rays from the magnetar 1E 1841-045
Michela Rigoselli, Roberto Taverna, Sandro Mereghetti +12
The Imaging X-ray Polarimetry Explorer (IXPE) observed for the first time highly polarized X-ray emission from the magnetar 1E 1841-045, targeted after a burst-active phase in Augu…
