On the equivalent effective temperature of massive young star clusters: The case of NGC 595
equivalent effective temperature massive star clusters
2011/9/27
The softness parameter is based on the relative intensity of several optical emission lines emitted by the gas ionized by young massive star clusters and can be used to derive the equivalent effective...
[O III] Equivalent Width and Orientation Effects in Quasars
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
The flux of the [OIII] line is considered to be a good indicator of the bolometric emission of quasars. The observed continuum emission from the accretion disc should instead be strongly dependent on ...
