This is an absolutely outstanding compilation summary of GZ SN Zoo supernovae discoveries by nilium. The amount of hard work, effort and care that went into creating this webpage speaks for itself. Ok nilium, you can't rest on your laurels....we will all be looking forward to the update of this page for 2012 discoveries! Keep up the great work!

I got this in an Email
 last night

While the Total Discoverd by me is Tiny compared with this Vast Number?

"So far, 1002 of the candidates that you've logged on and classified have been selected for follow up by the PTF team."

I alway"s thought some thing was Missing!

About 5% of total candidates collectively get the highest score ranking by the Zoo. About 20% of these highly scored candidates get spectroscopy because of the scarcity of this resource and other factors. Spectroscopy is considered the gold standard for SN classification, although other less reliable methods (photometry, proximity to a host galaxy, lack of motion on followup images) are used. Keep in mind that "candidates that you have logged on and classified have been selected for followup by the PTF team " does mean these will all get spectroscopy.  To date the Zoo has found ~2950 SN but only 1-2% of these have spectroscopic confirmation and are published in the ATels. These are reported in the "PTF weekly SN discovery report" and totaled annually by nilium in the "GZ Supernovae Discoveries Page". You have no doubt contributed to the discovery of many of the "unconfirmed" (no spectroscopy) SN listed on the Supernovae Discovery pages (the majority of all of our finds). While these are probably all true SN we do not have access to any specific science data on these finds (only PTF has access to this data).....all we have is the PTF ID #, the classifiers "names", and the discovery images.

Yet we are seing Shed Loads More and being told about them so the Ranking System is a bit Screwed!

The scoring system itself has not changed, but we may be getting better at it (practice makes perfect) so we may have more highly scored candidates. We may also be getting more total images to classify and therefore more candidates. At any rate Blackprojects, you have always been one of the most productive and involved classifiers in the SN Zoo.

So adding up all the SNs over the Three years i wind up with 69 Listed  but the emails i got said i had over a 1,045+ Confirmed?

"Dear Blackprojects

Good news everybody! 162 new supernovae candidates have just been uploaded to the site, so if you have a few minutes to spare we would love your help sorting through them. Click here to start classifying.

So far, 1045 of the candidates that you've logged on and classified have been selected for follow up by the PTF team.

Thanks for all your help with Galaxy Zoo Supernovae.

Stuart and Galaxy Zoo team"


So where did the rest end up?

Blackprojects, you co-discovered 69 spectroscopically confirmed SNe and 976 SNe that were not confirmed by spectroscopy but were judged to be SNe based on other parameters. The science data on your latter finds are in PTF's database. We do not have access to that database. The only SNe for which we have detailed information were those published by PTF in the ATel's as "The PTF weekly SN discovery report".
