Probing the nature of IGR J16493-4348: Spectral and temporal analysis of the 1-100 keV emission
A. B. Hill, A. J. Dean, R. Landi +5
IGR J16493-4348 was one of the first new sources to be detected by the INTEGRAL gamma-ray telescope in the 18-100 keV energy band. Based upon spatial coincidence the source was ori…
INTEGRAL observations of PSR J1811-1925 and its associated Pulsar Wind Nebula
A. J. Dean, A. De Rosa, V. A. McBride +6
We present spectral measurements made in the soft (20-100 keV) gamma-ray band of the region containing the composite supernova remnant G11.2-0.3 and its associated pulsar PSR J1811…
INTEGRAL detection of the pulsar wind nebula in PSR J1846-0258
V. A. McBride, A. J. Dean, A. Bazzano +6
We communicate the detection of soft (20--200 keV) gamma-rays from the pulsar and pulsar wind nebula of PSR J1846-0258 and aim to identify the component of the system which is resp…
IGR J22517+2218=MG3 J225155+2217: a new gamma-ray lighthouse in the distant Universe
L. Bassani, R. Landi, A. Malizia +7
We report on the identification of a new soft gamma ray source, namely IGR J22517+2218, detected with IBIS/INTEGRAL. The source, which has an observed 20-100 keV flux of ~4 x10^-11…
Broadband X-ray spectrum of the newly discovered broad line radio galaxy IGR J21247+5058
M. Molina, M. Giroletti, A. Malizia +7
In this paper we present radio and high energy observations of the INTEGRAL source IGR J21247+5058, a broad line emitting galaxy obscured by the Galactic plane. Archival VLA radio…
INTEGRAL observations of the Small Magellanic Cloud
V. A. McBride, M. J. Coe, A. J. Bird +10
The first INTEGRAL observations of the Small Magellanic Cloud (carried out in 2003) are reported in which two sources are clearly detected. The first source, SMC X-1, shows a hard…
An unexpected outburst from A0535+262
A. B. Hill, A. J. Bird, A. J. Dean +6
A0535+262 is a transient Be/X-ray binary system which was in a quiescent phase from 1994-2005. In this paper we report on the timing and spectral properties of the INTEGRAL detecti…
HESS J1616-508: likely powered by PSR J1617-5055
R. Landi, A. De Rosa, A. J. Dean +3
HESS J1616-508 is one of the brightest emitters in the TeV sky. Recent observations with the IBIS/ISGRI telescope on board the INTEGRAL spacecraft have revealed that a young, nearb…
The AGN nature of 11 out of 12 Swift/RXTE unidentified sources through optical and X-ray spectroscopy
R. Landi, N. Masetti, L. Morelli +9
The Swift Burst Alert Telescope (BAT) is performing a high Galactic latitude survey in the 14-195 keV band at a flux limit of ~10^{-11} erg cm^{-2} s^{-1}, leading to the discovery…
INTEGRAL high energy detection of the transient IGR J11321-5311
V. Sguera, A. Bazzano, A. J. Bird +5
Context: The transient hard X-ray source IGR J11321-5311 was discovered by INTEGRAL on June 2005, during observations of the Crux spiral arm. To date, this is the only detection of…
Polarisation studies of the prompt gamma-ray emission from GRB 041219a using the Spectrometer aboard INTEGRAL
S. McGlynn, D. J. Clark, A. J. Dean +6
The spectrometer aboard INTEGRAL, SPI, has the capability to detect the signature of polarised emission from a bright gamma-ray source. GRB 041219a is the most intense burst locali…
