Multiwavelength observations of GRB 110731A: GeV emission from onset to afterglow
LAT Collaboration, GBM Collaboration, Swift Collaboration +2
We report on the multiwavelength observations of the bright, long gamma-ray burst \GRB, by the \Fermi and \Swift observatories, and by the MOA and GROND optical telescopes. The ana…
Binary Millisecond Pulsar Discovery via Gamma-Ray Pulsations
H. J. Pletsch, L. Guillemot, H. Fehrmann +150
Millisecond pulsars, old neutron stars spun-up by accreting matter from a companion star, can reach high rotation rates of hundreds of revolutions per second. Until now, all such "…
GRB110721A: An extreme peak energy and signatures of the photosphere
The Fermi LAT Collaboration, the GBM Collaboration, A. Pe'er
GRB110721A was observed by the Fermi Gamma-ray Space Telescope using its two instruments the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM). The burst consisted o…
Multi-wavelength observations of blazar AO 0235+164 in the 2008-2009 flaring state
M. Ackermann, M. Ajello, J. Ballet +208
The blazar AO 0235+164 (z = 0.94) has been one of the most active objects observed by Fermi Large Area Telescope (LAT) since its launch in Summer 2008. In addition to the continuou…
Gamma-ray observations of the Orion Molecular Clouds with the Fermi Large Area Telescope
M. Ackermann, M. Ajello, A. Allafort +142
We report on the gamma-ray observations of giant molecular clouds Orion A and B with the Large Area Telescope (LAT) on-board the Fermi Gamma-ray Space Telescope. The gamma-ray emis…
Fermi-LAT Observations of Two Gamma-Ray Emission Components from the Quiescent Sun
A. A. Abdo
We report the detection of high-energy gamma rays from the quiescent Sun with the Large Area Telescope (LAT) on board the Fermi Gamma-Ray Space Telescope (Fermi) during the first 1…
