Swift Supernova Presentation Plots

Here are a few general purpose plots highlighting Swift's SN observations.  Specific science results can be pulled from the papers, but this is just to show a few of the global characteristics that are science-y enough for the specific science in the currently published suite of papers.  Some plots like this might appear in my archive paper(s) though.



The above plot includes a well observed supernova from all of the major classes and most of the subclasses.  The redshift limit on the upper right refers to the distance at which we could detect a particular supernova phase with Swift UVOT for a limiting magnitude of uvm2~20.  
The Swift UVOT data could similar predict the detectability of supernovae 
by future ultraviolet missions.



Many satellites have contributed ultraviolet observations of supernovae over the years, but Swift has revolutionized the field.  Large samples allow the differences within subclasses to be studied in detail.  http://people.physics.tamu.edu/pbrown/SwiftSN/UVexplosionSwiftSNe.png

Redshift distribution of all the supernovae observed by Swift.  95% of the supernovae are at redshifts less than 0.05, but Superluminous SNe are detectable to much higher distances.  http://people.physics.tamu.edu/pbrown/SwiftSN/redshift_allSNe.png

Fraction of Swift supernova observations of different type of supernovae.  All subclasses relating to the broader phenomological class are grouped together.  ? includes possible supernova imposters, LBV eruptions, or explosions of unknown origin.    http://people.physics.tamu.edu/pbrown/SwiftSN/SwiftSNpietypes.png
Number of Supernovae observed in the Ultraviolet each year from a variety of spacecraft.  Caveats: a few Supernovae are double counted if observed by multiple spacecraft (e.g. SNe 1987A and 1992A).  Also, they are plotted with respect to the year of the supernova rather than the date of the observation.  http://people.physics.tamu.edu/pbrown/SwiftSN/UVexplosionSNeSwiftontop.png
