Star formation history plotted directly from the SFR.txt file produced by SWIFT.
Stellar Mass Evolution
Evolution of the stellar mass plotted directly from the statistics.txt file produced by SWIFT, compared with assorted observational estimates.
Stellar Mass-Star Formation Rate (100 kpc Stellar Mass)
All galaxies, including those deemed to be passive (below 0.01 / Gyr sSFR), are included in the median line.
Specific Star Formation Rate - Stellar Mass (100 kpc) for active galaxies
Only active galaxies (threshold is above 0.01 / Gyr sSFR) are included in the median line.
Specific Star Formation Rate (100 kpc) - Halo Mass
Only active galaxies (threshold is above 0.01 / Gyr sSFR) are included in the median line.
Star Formation Rate divided by Halo Mass (100 kpc) - Halo Mass
Only active galaxies (threshold is above 0.01 / Gyr sSFR) are included in the median line
Passive Fraction - Stellar Mass (100 kpc)
A galaxy is determined as being passive if it has a sSFR below 0.01 / Gyr.
Passive Fraction - Stellar Mass (100 kpc aperture, centrals)
A galaxy is determined as being passive if it has a sSFR below 0.01 / Gyr. This figure shows only the central galaxies (structure type 10).
Star Formation Rate Function (100 kpc aperture)
100 kpc aperture galaxy star formation rate function, showing all galaxies with a fixed bin-width of 0.2 dex.
Star Formation Rate Function (100 kpc aperture)
100 kpc aperture galaxy star formation rate function, showing all galaxies with an adaptive bin-width.
$f_E$ as a Function of Birth Density
Feedback energy fractions $f_E$ shown against the birth densities for the stars. Any variation here is due to differing metallicity of the gas.
Birth Density-Metallicity Plane
Birth density-metallicity plane. Contour lines show stars formed at all epochs, with the background color map showing the feedback energy fraction associated with this particle's feedback event.
Stellar Mass Function (100 kpc aperture)
100 kpc aperture GSMF, showing all galaxies with a fixed bin-width of 0.2 dex.
