High energy -ray emission from PSR B125963 during 2014 and 2010 periastron passages
G. Andrea Caliandro, C. C. Teddy Cheung, Jian Li +2
PSR B125963/SS 2883 is a -ray binary system composed of a radio pulsar in a long (1236.7 days) and elliptical () orbit around a Be star. In its 2010 periastron pas…
A new concept of y-ray telescope. LArGO: Liquid Argon Gamma-ray Observatory
Giuseppe Andrea Caliandro, Biagio Rossi, Francesco Longo +4
LArGO (Liquid Argon Gamma-ray Observatory) consists of a new design for a -ray telescope, which exploits the idea of using a Liquid Argon Time Projection Chamber (LAr-TPC) as tr…
A method for evaluating the expectation value of a power spectrum using the probability density function of phases
G. A. Caliandro, D. F. Torres, N. Rea
Here, we present a new method to evaluate the expectation value of the power spectrum of a time series. A statistical approach is adopted to define the method. After its demonstrat…
The outburst decay of the low magnetic field magnetar SGR 0418+5729
N. Rea, G. L. Israel, J. A. Pons +20
We report on the long term X-ray monitoring of the outburst decay of the low magnetic field magnetar SGR 0418+5729, using all the available X-ray data obtained with RXTE, SWIFT, Ch…
The strange case of HESS J0632+057 and the γ-ray High Mass X-ray Binaries
G. A. Caliandro, A. B. Hill
In the last decade Cherenkov telescopes on the ground and space-based γ-ray instruments have identified a new class of high mass X-ray binaries (HMXB), whose emission is dominated…
Unveiling the super-orbital modulation of LSI +61 303 in X-rays
Jian Li, Diego F. Torres, Shu Zhang +5
We found evidence for the super-orbital modulation in the X-ray emission of LS I +61 303 from the longest monitoring date by the RXTE. The time evolution of the modulated fraction…
Impact of the orbital uncertainties on the timing of pulsars in binary systems
G. Andrea Caliandro, Diego F. Torres, Nanda Rea
The detection of pulsations from an X-ray binary is an unambiguous signature of the presence of a neutron star in the system. When the pulsations are missed in the radio band, thei…
LOFT: the Large Observatory For X-ray Timing
M. Feroci, J. W. den Herder, E. Bozzo +245
The LOFT mission concept is one of four candidates selected by ESA for the M3 launch opportunity as Medium Size missions of the Cosmic Vision programme. The launch window is curren…
Unveiling the super-orbital modulation of LS I +61 303 in X-rays
Jian Li, Diego F. Torres, Shu Zhang +5
From the longest monitoring of LS I +61 303 done to date by the Rossi X-ray Timing Explorer (RXTE) we found evidence for the long-sought, years- long modulation in the X-ray emissi…
INTEGRAL observations of the gamma-ray binary 1FGL J1018.6-5856
Jian Li, Diego F. Torres, Yupeng Chen +5
The Fermi-LAT collaboration has recently reported that one of their detected sources, namely, 1FGL J1018.6-5856, is a new gamma-ray binary similar to LS 5039. This has prompted eff…
Broad band X-ray spectra of short bursts from SGR 1900+14
M. Feroci, G. A. Caliandro, E. Massaro +2
We report on the X-ray spectral properties of 10 short bursts from SGR1900+14 observed with the Narrow Field Instruments onboard BeppoSAX in the hours following the intermediate fl…
