The relation of optical/UV and X-ray emission in low-luminosity active galactic nuclei
relation optical/UV X-ray emission low-luminosity active galactic nuclei
2011/10/9
We study the relation of optical/UV and X-ray emission in the low luminosity active galactic nuclei (LLAGNs), using a sample of 49 sources including 28 local Seyfert galaxies and 21 low-ionization nuc...
Her X-1: the positive cyclotron line energy / luminosity correlation
pulsars: individual: – stars: neutron – stars: binaries
2011/9/28
Studies of some bright, super-Eddington transient pulsars show a negative correlation between the energy of the cyclotron resonance scattering feature (CRSF) and the bolometric luminosity. For Her X-1...
