ToO Observations of New Galactic Gamma-ray Transients Discovered with Fermi
Abstract
During the first year of operation, the Fermi gamma-ray observatory has detected two new transient GeV sources in the Galactic plane. The nature of these Galactic gamma-ray transients is currently not known. We propose XMM-Newton ToO observations of new transients discovered with the Fermi LAT in the Galactic plane. The XMM-Newton observations will enable us to more accurately localize the transients, identify counterparts at other wavelengths, determine their X-ray to gamma-ray flux ratio, measure their X-ray spectrum, and characterize their variability and decay time scale. This proposal is part of a multiwavelength program that includes observations at radio and TeV energies.
