We present a catalog of high-energy gamma-ray sources detected by the Large Area Telescope (LAT), the primary science instrument on the Fermi Gamma-ray Space Telescope (Fermi), during the first 11
Fermi Large Area Telescope Second Source Catalog
We present the second catalog of high-energy γ-ray sources detected by the Large Area Telescope (LAT), the primary science instrument on the Fermi Gamma-ray Space Telescope (Fermi), derived from data
Relativistic jet activity from the tidal disruption of a star by a massive black hole
Observations of a bright X-ray flare from the extragalactic transient Swift J164449.3+573451 conclude that they have captured the onset of relativistic jet activity from a supermassive black hole.
A change in the optical polarization associated with a γ-ray flare in the blazar 3C 279
It is widely accepted that strong and variable radiation detected over all accessible energy bands in a number of active galaxies arises from a relativistic, Doppler-boosted jet pointing close to our
Announcement of the Swift/BAT Hard X-ray Transient Monitor
The Swift/Burst Alert Telescope (BAT) hard X-ray transient monitor provides near real-time coverage of the X-ray sky in the energy range 15-50 keV. The BAT observes 88% of the sky each day with a
The fermi large area telescope on orbit: Event classification, instrument response functions, and calibration
The Fermi Large Area Telescope (Fermi-LAT, hereafter LAT), the primary instrument on the Fermi Gamma-ray Space Telescope (Fermi) mission, is an imaging, wide field-of-view, high-energy γ-ray
The three types of high-mass X-ray pulsator
High mass X-ray pulsators are shown to be divisible into three distinct groups on the basis of their observational properties: 1) the Be star systems, 2) non-Be star systems with long pulse periods,
A Systematic Search for Periodicities in RXTE ASM Data
We present the results of a systematic search in 8.5 years of Rossi X-ray Timing Explorer All-Sky Monitor data for evidence of periodicities. The search was conducted by application of the
A Population of Gamma-Ray Millisecond Pulsars Seen with the Fermi Large Area Telescope
Fermi Large Area Telescope data is searched for pulsations from all known millisecond pulsars outside of stellar clusters, finding gamma-ray pulsations for eight of them, suggesting that they share the same basic emission mechanism with standard gamma-Ray pulsars.
Fermi LAT Observations of LS 5039
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 results indicate
