PublicaciónImplications of Burst Oscillations from the Slowly Rotating Accreting Pulsar IGR J17480-2446 in the Globular Cluster Terzan 5
The recently discovered accreting X-ray pulsar IGR J17480-2446 spins at a frequency of ~11 Hz. We show that Type I X-ray bursts from this source display...

PublicaciónIndirect evidence for an active radio pulsar in SAX J1808.4-3658 during quiescence
Millisecond radio pulsars are neutron stars that have been spun-up by the transfer of angular momentum during the low-mass X-ray binary phase. The transition...

PublicaciónINTEGRAL observations of the peculiar BeX System SAX J2103.5+4545
We present an INTEGRAL data analysis of the X-ray transient SAX J2103.5+4545 during two outbursts detected in December 2002. The INTEGRAL coordinates and error...

PublicaciónLight-curve models for a pulsar orbiting a Kerr black hole
We have studied the signal received by a distant observer from a pulsar orbiting a stellar black hole. The binary system has a non-eccentric orbit and the most...

PublicaciónLikely optical counterpart of the cool middle-aged pulsar J1957+5033
The 840-kyr-old pulsar PSR J1957+5033, detected so far only in γ- and X-rays, is a nearby and rather cool neutron star with a temperature of 0.2-0.3 MK, a...

PublicaciónMAGIC and Fermi-LAT gamma-ray results on unassociated HAWC sources
The HAWC Collaboration released the 2HWC catalogue of TeV sources, in which 19 show no association with any known high-energy (HE; E ≳ 10 GeV) or very-high...

PublicaciónMAGIC reveals a complex morphology within the unidentified gamma-ray source HESS J1857+026
Aims: HESS J1857+026 is an extended TeV gamma-ray source that was discovered by H.E.S.S. as part of its Galactic plane survey. Given its broadband spectral...

PublicaciónMAGIC Upper Limits for Two Milagro-detected Bright Fermi Sources in the Region of SNR G65.1+0.6
We report on the observation of the region around supernova remnant G65.1+0.6 with the stand-alone MAGIC-I telescope. This region hosts the two bright GeV gamma...
