The Ion and Charged Aerosol Growth Enhancement (ION-CAGE) code: A numerical model for the growth of charged and neutral aerosols
Jacob Svensmark, Nir J. Shaviv, Martin B. Enghoff +1
The presence of small ions influences the growth dynamics of a size distribution of aerosols. Specifically the often neglected mass of small ions influences the aerosol growth rate…
Near-Earth supernova activity during the past 35 Myr
Mads Sørensen, Henrik Svensmark, Uffe Gråe Jørgensen
Here we combine observations of open clusters (OCs) with single- and binary population synthesis models and a Galactic potential to reconstruct the SN activity of these OCs during…
Approximate analytical solutions to the condensation-coagulation equation of aerosols
Naftali R. Smith, Nir J. Shaviv, Henrik Svensmark
We present analytical solutions to the steady state injection-condensation-coagulation equation of aerosols in the atmosphere. These solutions are appropriate under different limit…
Evidence of nearby supernovae affecting life on Earth
Henrik Svensmark
Observations of open star clusters in the solar neighborhood are used to calculate local supernova (SN) rates for the past 510 million years (Myr). Peaks in the SN rates match pass…
Response of Cloud Condensation Nuclei (> 50 nm) to changes in ion-nucleation
Henrik Svensmark, Martin B. Enghoff, Jens Olaf Pepke Pedersen
In experiments where ultraviolet light produces aerosols from trace amounts of ozone, sulphur dioxide, and water vapour, the number of additional small particles produced by ioniza…
How did the Sun affect the climate when life evolved on the Earth?
C. Karoff, H. Svensmark
Using kappa Ceti as a proxy for the young Sun we show that not only was the young Sun much more effective in protecting the Earth environment from galactic cosmic rays than the pre…
