A search for spectral hysteresis and energy-dependent time lags from x-ray and tev gamma-ray observations of mrk 421
(American Astronomical Society, 2016-12-22)
Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at different wavelengths, especially in the ...
Very high energy observations of the binaries v 404 cyg and 4u 0115+634 during giant x-ray outbursts
(American Astronomical Society, 2016-10-31)
Transient X-ray binaries produce major outbursts in which the X-ray flux can increase over the quiescent level by factors as large as 10(7). The low-mass X-ray binary V 404 Cyg and the high-mass system 4U 0115+634 underwent ...
Tev gamma-ray observations of the galactic center ridge by veritas
(American Astronomical Society, 2016-04-22)
The Galactic Center ridge has been observed extensively in the past by both GeV and TeV gamma-ray instruments revealing a wealth of structure, including a diffuse component and the point sources G0.9+0.1 (a composite ...
Exceptionally bright tev flares from the binary ls i +61° 303
(American Astronomical Society, 2016-01-19)
The TeV binary system LS I +61 degrees 303 is known for its regular, non-thermal emission pattern that traces the orbital period of the compact object in its 26.5 day orbit around its B0 Ve star companion. The system ...
A search for very high energy gamma rays from the missing link binary pulsar j1023+0038 with veritas
(American Astronomical Society, 2016-11-08)
The binary millisecond radio pulsar PSR J1023+0038 exhibits many characteristics similar to the gamma-ray binary system PSR B1259-63/LS 2883, making it an ideal candidate for the study of high-energy nonthermal emission. ...
