Bacillus sp. X-3

We study the radio/X-ray correlation in Cyg X-3. It has been known that the soft and hard X-ray fluxes in the hard spectral state… Expand

There are no known stellar-origin double black hole (BH-BH) or black-hole-neutron-star (BH-NS) systems. We argue that Cyg X-3 is… Expand

Cyg X-3 is a highly interesting accreting X-ray binary, emitting from the radio to high-energy gamma-rays. It consists of a… Expand

We study models of the ?-ray emission of Cyg X-3 observed by Fermi. We calculate the average X-ray spectrum during the ?-ray… Expand

We present almost-simultaneous detections of Cygnus X-1 in the radio and mm regimes, obtained during the low/hard X-ray state… Expand

We consider propagation of very high energy (VHE) gamma-rays in the radiation field of a massive star in the binary system Cen X… Expand

By means of population synthesis we find that the expected Galactic number of black holes with massive helium star companions is… Expand

It is now generally accepted that accretion of matter onto a compact object (white dwarf, neutron star or black hole) is one of… Expand

We have used the twin 11-m diameter mirrors of the NASA Jet Propulsion Laboratory's solar energy facility to observe high-energy… Expand
