Transport of short-lived halocarbons to the stratosphere over the Pacific Ocean [PDF]

Atmospheric Chemistry and Physics, 2020
The effectiveness of transport of short-lived halocarbons to the upper troposphere and lower stratosphere remains an important uncertainty in quantifying the supply of ozone-depleting substances to the stratosphere.

A Relationship between Nuclear Black Hole Mass and Galaxy Velocity Dispersion [PDF]

, 2000
We describe a correlation between the mass Mbh of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion σe within the half-light radius.

The Slope of the Black Hole Mass versus Velocity Dispersion Correlation [PDF]

, 2002
Observations of nearby galaxies reveal a strong correlation between the mass of the central dark object MBH and the velocity dispersion σ of the host galaxy, of the form log(MBH/M☉) = α + β log(σ/σ0); however, published estimates of the slope β span a ...
