Last week I had a fabulous opportunity to sit down and talk with Galaxy Zookeepers Jordan Raddick and Chris Lintott. Here is the audio from our conversation – Enjoy!

Star Stryder: An Interview with Zookeepers [Mp3 – 13.8 Mb]

As you may have periodically read in this blog, I’m currently working on a project that is going to require a lot of work with the Sloan Digital Sky Survey (SDSS – the online catalogue users of Galaxy Zoo are working with). Getting at the data I want is going to require me to get better at jumping through the web forms on SDSS than I am right now, but while I’m still learning, I want share a few of the tricks I’ve learned.

Trick 1: So, you want a pretty picture of the field around your favorite obscure star/galaxy/cluster

1. Go to this link (For navigate tool)
2. Type in the coordinates of your object (NOTE: it has RA in decimal degrees!!!!)
3. Re-center, zoom, and unzoom
4. Download the image your telescope just can’t quite pull off.

The screen capture above right is for AH Leo, my favorite little variable.

Trick 2: Get numerical Data without fighting with IRAF! You can then get quick photometry for the objects in a given field here, or do a more detailed search – and this is what I’ll be using with my student – here. When using that form to download freely available spectra of galaxies around the center of an Abell cluster, it is possible to confirm spectra and get a sense of which of the shiny galaxies are cluster members and which are foreground objects.

Cool.

I’m making a start, and might be making progress (or I might be delusional). As I tell my grad students, often it is required that you try grabbing / processing / plotting / etc your data at least 4 times before you know you have what you meant to get.

But I’m making a start. And now you know how to make your start.

And we know who the zoo keepers are when we need help.
