Cygnus X-1 is located at the centre of the square on the image. The star visible at this location is called HDE 226868 and is in orbit around Cygnus X-1. HDE 226868 itself is more than 10 times fainter than the naked eye can see. Another star, just above HDE 226868, is a back...
(4) The MeV tail emissions, which produces a strongly linearly polarized signal, are emitted inside the binary system. The location of the emissions is very close to the inner region of the jet.doi:10.1088/0004-637X/788/2/143Jianfu ZhangBing XuJufu Lu...
It was detected by Uhuru at 2U 2142+38. HEAO 1, OSO 7, Ariel 5, and ROSAT satellites have observed Cyg X-2. A refinement on the location of Cyg X-2 placed it at J1950 RA 21h 42m 48s Dec +38° 11. 展开 收藏 报错 分享 ...
The mean (± 95% CI) estimated rates of net energy gain values for Bewick's Swans were 2.0 (± 0.5) xBMR for adults and 1.4 (± 0.6) xBMR for cygnets (Table 1). The value for Bewick's Swan cygnets was the lowest estimated for any swan species and age class, whilst the maximum...

1 Stockholm Observatory, SE-133 36, Saltsj˝obaden, Sweden –2 – ABSTRACT We present interplanetary network localization, spectral, and time history information for 7 episodes of exceptionally intense gamma-ray emission from Cygnus X-1. The outbursts occurred between 1995 and 2003, with duration...
It lies 7' from the centroid of the TeV emission, which places it outside of the claimed 2 sigma location (r = 4.8'). A possible eclipse or "dip" transition is seen in its light curve. With a peak 1-10 keV luminosity of 7 x 10^(32) (d/1.7 kpc})^2 ergs s^(-1), this ...

For the 'first-light' images, ESA pointed Integral at Cygnus X-1. Cygnus X-1 is about 10 000 light years from Earth and one of the brightest high-energy emitters in the sky. It was discovered in the 1960s and is thought to be...
Cygnus is a two-axis radiographic x-ray facility designed to drive rod-pinch diode loads at 2.25 MV with a spot size of about 1 mm producing 4 Rads at 1 meter. This x-ray source was developed to support the Sub-Critical Experiments Program (SCE) at the Nevada Test Site (NTS) and ...
