Fermi LAT Observations of LS 5039
The Fermi LAT collaboration
The first results from observations of the high mass X-ray binary LS 5039 using the Fermi Gamma-ray Space Telescope data between 2008 August and 2009 June are presented. Our result…
The nature of the X-ray binary IGR J19294+1816 from INTEGRAL, RXTE, and Swift observations
J. Rodriguez, J. A. Tomsick, A. Bodaghee +4
We report the results of a high-energy multi-instrumental campaign with INTEGRAL, RXTE, and Swift of the recently discovered INTEGRAL source IGR J19294+1816. The Swift/XRT data all…
Fermi LAT Observations of LS I +61 303: First detection of an orbital modulation in GeV Gamma Rays
A. A. Abdo
This Letter presents the first results from the observations of LSI +61 303 using Large Area Telescope data from the Fermi Gamma-Ray Space Telescope between 2008 August and 2009 Ma…
Early Fermi Gamma-ray Space Telescope Observations of the Quasar 3C 454.3
LAT Collaboration, A. A. Abdo
This is the first report of Fermi Gamma-ray Space Telescope observations of the quasar 3C 454.3, which has been undergoing pronounced long-term outbursts since 2000. The data from…
Detailed Radio to Soft Gamma-ray Studies of the 2005 Outburst of the New X-ray Transient XTE J1818-245
M. Cadolle Bel, L. Prat, J. Rodriguez +11
XTE J1818-245 is an X-ray nova that experienced an outburst in 2005, first seen by the RXTE satellite. The source was observed simultaneously at various wavelengths up to soft gamm…
Identifications of Five INTEGRAL Sources via Optical Spectroscopy
Suzanne C. Butler, John A. Tomsick, Sylvain Chaty +6
The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is discovering hundreds of new hard X-ray sources, many of which remain unidentified. We report on optical spectrosco…
VLT/NACO near-infrared observations of the transient radio magnetar 1E 1547.0-5408
R. P. Mignani, N. Rea, V. Testa +9
Despite about a decade of observations, very little is known about the optical and infrared (IR) emission properties of the Soft Gamma-ray Repeaters (SGRs) and of the Anomalous X-r…
