The spectral variability is generally characterized by a hardening of the source spectra as their luminosities increase.

Ultraluminous X-ray Sources ULXs are point like, non-nuclear X-ray sources situated outside the nucleus of their host galaxy, that have X-ray luminosities in excess of 1039 erg s-1.

A DELIGHT! 2010

Both RHIC and the LHC have plans to undertake an upgrade to achieve an increase of their respective luminosities by up to a factor of 10.

IIRC, there was a push in the late '90s and early '00s to try to establish GRB luminosities as standard candles.

And further, the paper mentions that ~7% of the 100 Super Star Clusters discovered have luminosities exceeding that of 30 Doradus the Tarantula Nebula = NGC 2070.

So as I understand SNIs are a standard candle or have consistent luminosities because they have a consistent mass.

Using the well known relationship between absolute and apparent luminosities Hubble found that the velocity of galaxies, based on redshift, and their distance measured by Cepheid variables was
