Spectral Energy Distributions Of Quasars Research Articles

Are Weak Bump Quasars Edge-on Sources?

The 'big bump' is one of the most striking features of the spectral energy distribution of quasars. It extends from optical light to EUV and soft X-ray. It has been suggested that this is due to the thermal radiation from an accretion disk within tens of Schwarzschild radii from a black hole However, McDowell et al. revealed a few quasars with a weak
