Discussion Overview

The discussion revolves around the analysis of simulated galaxies using data from the SDSS telescope, specifically focusing on a survey created by a participant for classifying these galaxies. The scope includes aspects of cosmological simulations, human classification versus numerical techniques, and outreach for survey participation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • A participant is analyzing high-volume cosmological simulations for a master's project and has created a survey for galaxy classification.
  • The survey aims to gather feedback on the classification of simulated galaxies and compare human classification with numerical analysis.
  • Some participants find the survey questions straightforward, drawing on their previous experience with galaxy classification programs.
  • There is a request for suggestions on how to increase survey participation from a broader audience.

Areas of Agreement / Disagreement

Participants generally agree that the survey questions are straightforward, but there is uncertainty about whether all potential participants will understand them. The discussion about outreach strategies remains open-ended.

Contextual Notes

The discussion does not resolve whether the survey effectively communicates its intent to a layman audience, nor does it clarify the specific metrics or methods used in the numerical analysis for comparison.

Who May Find This Useful

Individuals interested in cosmology, galaxy classification, data analysis, and outreach strategies for scientific surveys may find this discussion relevant.

Hi Guys!

My first post here, I'm working on analysing the output of some contemporary high-volume cosmological simulations for my masters project.

As a bit on the side, I've had a go at reproducing how the SDSS telescope would view the simulated galaxies with various colour bands, and creating colour images. I've put a survey up on a website to see if i can get people to classify my galaxies in a galaxy-zoo kind of way. I was wondering if any of you pros could give me some feedback or do the survey for a few galaxies?

It's aimed at a layman audience, with simple questions. The statistics of the survey could give me some really nice context for my more rigorous numerical analysis, and ultimately how human classification stacks up against my numerical techniques.Cheers!

Thanks for the survey participation so far, do the questions make sense?

also any ideas to get it out to lots of people would be welcomed! :D
 
the questions are straight forward to the viewed galaxy. Mind I've also participated in galaxy classification from an interactive NASA program that was a while ago though lol not sure if I even have the link to it.

Thanks! yeah its hard to gauge whether everyone would be able to understand it. I had a look at galaxy zoo before hand to try and pitch it right
