Sex work involving circumcised males falsifies evolution while proving Jesus to be a Mithra copycat!

My avatar is norbornane, a molecule in organic chemistry that I was delighted to come across at university, as it gives rise to the norbornyl cation, which is about the only example of 3-centre, 2-electron bonding in carbon chemistry. (Boron, which is next to carbon in the Periodic Table, does that all the time). So the norbornyl cation is one of those "rule-breaking" things in science which makes the subject exciting.

Details here, if you are up for a full-on nerd-out: 2-Norbornyl cation - Wikipedia

But why are you up all night sifting through galaxies? Are you working at an observatory or something?

Thank you for the link. My highest chem was undergrad Chem II so, I skimmed enough to know I'd have to focus to glean anything really interesting though!

My job is just a night tech support job; I get emails when stuff breaks and I go fix it. So I work maybe 2 hours of a 10 hour shift. The rest is studying, hobbies, and research; but it's all been thesis for the summer. I'm working with the HST CANDELs surveys, so a portion of the sky about the same apparent diameter as the moon (maybe a moon and a half), but it's a LOT of galaxies, and I have to make databases from different instruments and observations so I can match them by right ascension and declination and make subsets. So for instance if I want to look at all the galaxies above x mass, or between x and y redshift, or both. The groundwork will make everything much easier later.

I'm being paid right now to type this message, listening to music, Youtube on in the background... and should be working on my thesis (ha! ^.^).

Best damn college job I've ever had. Wish I had it during undergrad too.

Excuse my ignorance but CANDELS is looking at galaxies in the IR, isn't it?

I finished 3D printing this thing and am in the process of painting him/her/it.

Yep, mostly IR. Used the Wide Field Camera 3 and Camera For Surveys (or whatever its exact name is, the ACS. Must be Advanced Camera for Surveys then). I've got five different fields of stuff, COSMOS, UDS, GOODS-N (north) and GOODS-S (south), and somehow, I'm forgetting the fifth.

It's a lot of galaxies. I think when I was messing with GOODS-S earlier there were 97k even after making a subset to cut out galaxies with chunks of data missing, and GOODS-S is one of the smaller areas. (COSMOS is huge).

This is what the raw image cubes look like:

This was found on Google but that is accurate, they look like this. So they come as some 88 GB of these and then the rest is so, so many tables.

Do you have to classify these from their appearance into galaxy types or something? And what are z and p?

Thankfully no (not by hand if that's what you mean), I have algorithms for that. My PI and I have some source extraction stuff that assigns a diskiness value (and I love that I get to use a word like "diskiness" all seriously). There are a lot of derived values that we look for, like sersic profile (intensity dropoff as a function of distance from center), color (blue = star forming, red = dead... mostly), and yes, type (ETG's and LTG's, which is very stupid because these stand for "early type" and "late type" galaxies, which are exactly the opposite of what they're assigned to but we still call them that because of dumb historical reasons).

z is redshift. p is related to whether there is a bar-shape.

He's so humble. Implicit in the word 'Try' is the humility to accept that his attempt may fail.

That's the kind of dumb trick I pull. Anyhoo, it worked. I'm doing a blog that reviews alcohol free beers. Somebody must be looking at it because I've recently been asked if I'd like to be sent some free beers to review. Free beers? Yes, I had to think about that quite a long time. :D

Sex blood magic involving socialist circumcised males falsifies theistic evolution and young earth creationism while proving Jesus to be a Lemurian starseed as spoken of by the prophet Bahaullah when he commissioned Krishna to combat gay feminist war agendas during the Bush Jr administration as part of the Scientology illuminati conspiracy under the veil of a reincarnated Lenin

Before your time? It was probably the first UK AF beer, advertised by the football manager Lawrie McMenemy. Totally dreadful.

What do you think is the point of it?

The same as for any alcoholic drink: a good taste (which alcohol-free beer cannot really manage) and the gentle sense of warmth, relaxation and mild loosening of the tongue that is such a boon at any social gathering where drinks are served.
