MOMO IV: The complete Swift X-ray and UV/optical light curve and characteristic variability of the blazar OJ 287 during the last two decades
S. Komossa, D. Grupe, L. C. Gallo +5
We are carrying out a dense monitoring of the blazar OJ 287 with Swift since late 2015 as part of our project MOMO (Multiwavelength Observations and Modeling of OJ 287). This is th…
Variability and Spectral Characteristics of Three Flaring Gamma-ray Quasars Observed by VERITAS and Fermi-LAT
C. B. Adams, J. Batshoun, W. Benbow +63
Flat spectrum radio quasars (FSRQs) are the most luminous blazars at GeV energies, but only rarely emit detectable fluxes of TeV gamma rays, typically during bright GeV flares. We…
The Instrument of the Imaging X-ray Polarimetry Explorer
Paolo Soffitta, Luca Baldini, Ronaldo Bellazzini +78
While X-ray Spectroscopy, Timing and Imaging have improved verymuch since 1962, when the first astronomical non-solar source was discovered, especially with the launch of Newton/X-…
Project MOMO: Multiwavelength Observations and Modelling of OJ 287
S. Komossa, D. Grupe, A. Kraus +9
Our project MOMO (Multiwavelength observations and modelling of OJ 287) consists of dedicated, dense, long-term flux and spectroscopic monitoring and deep follow-up observations of…
Fermi Large Area Telescope Performance After 10 Years Of Operation
The Fermi LAT Collaboration, M. Ajello, W. B. Atwood +126
The Large Area Telescope (LAT), the primary instrument for the Fermi Gamma-ray Space Telescope (Fermi) mission, is an imaging, wide field-of-view, high-energy gamma-ray telescope,…
Catalog of Long-Term Transient Sources in the First 10 Years of Fermi-LAT Data
L. Baldini, J. Ballet, D. Bastieri +112
We present the first Fermi Large Area Telescope (LAT) catalog of long-term -ray transient sources (1FLT). This comprises sources that were detected on monthly time intervals dur…
