Give peas a chance!

[Rick Nowell]

I had a quick look at the link Rick posted for those Chinese Astronomers about Wolf-Rayet galaxies. Here are the first 5 on their list.

Do we have to have all 174 on the list and their spectra? Seems a lot, especially when there are the ones below:

http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=SHOC01
http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=SHOC02
http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=SHOC03
etc etc

The SHOC catalogue is a very good place to look for emission-line galaxies, as it is a survey from SDSS on
ELGs. I forget how big the catalogue is.

They also have a flag for W-R galaxies, though they mainly use Schaerer, as there
was no Chinese survey then.

Any good ? Or is it a star ? (The asteroid (1992 FZ) has already been posted).

Yes Rick
Thats why I asked for some feedback after the second post

I wont do any more until i get some more feedback.
I feel guilty about filling up pages.

I notice that you have been cutting and pasting in a haphazard manner in the Wolf Raynet Thread.
Personaly I find the CAP (Cut And Paste) thing boring and only volunteered as a communal participation thing.
(Someone has to clean the toilets)
Personally for me its much more thrilling/interesting to do the classification thing and find your own peas.
So if someone with a bit of authority could give us some direction. state your credentials and please do.

Personally, I prefer the policy of benign neglect. We're all allegedly adults here, so there should be room for everyone to do their own thing.
Since GalaxyHuntersInc is only putting up the captures and charts of galaxies no one has found before, they're not even reposts. The uninterested can scroll past or ignore the thread altogether. I for one am enjoying looking at them in this format, and even if no one did, who is it hurting? I can't believe bandwidth can be an issue when we have people with picture signatures and the second largest thread is "Just Chat". I see a lot of posting I think is silly or sloppy, but that's their call to make. More rules and control equals more arbitrary one-size-fits-all thinking and less freedom for participation and insight. Galaxyzoo seems to be doing fine as is, a merry multicultural chaos.

And I think lenticulars are more like a lima bean someone stepped on than a chickpea, but that's also just my opinion.

I just thought it was a bit one-dimensional going through the whole list. They are all going to have
a great deal of ionisation going on, obviously, as they are W-R galaxies. Do we need to see them all?
I started going through the Chinese W-R list myself, but found out you had already got there! But I
am not bitter.

The SHOC catalogue might be a good thing to wade through; it is all emission line objects, so if you
could be bothered to find the attractive looking ones that would be cool. I myself am chewing my way
through the Markarian catalogue at the moment. I haven't classified anything for weeks- I don't feel
I am obliged to. If the object is amazing and it lurks within SDSS, why not post it? The ARP Peculiar Galaxy
Atlas thread I enjoyed doing and took it took ten hours. The only way I would have seen so much of the
catalogue is by going after it. And what amazing objects I have seen.

Thanks for the above URL - and thanks for all the efforts in posting them; truely wonderful pictures !!
Whats the URL for the catalogue ?

Which catalogue is that? I am not sure what you are asking for...

Is the Markarian catalogue to which you refer searchable on line ?
If so, what is it's URL ?

Going back a few posts, the blue thing FermatsBrother posted (next to an asteroid) doesn't look like an OIII "Pea" to me. Even if the redshift value is wrong, the chart looks more like a blue star than anything. Frustratingly, I've seen a chart like this before, but have no recollection of when or where. Maybe it belongs in "Oddballs".

specClass says Galaxy but this looks like a pea to me.

There may well be...what I use is the below address and just go through the list. This url
lead you to a page in NED, where, if there is a picture in SDSS, it will be in the list of catalogues
(NGC, ARP, Messier, UGC etc). If there is a reference to SDSS, then if you scroll down the page
you will come to a orange/pink table which will have
"Query SDSS Sky Server -- SDSS J102332.62+105735.0"
which you click on. This takes you to Skyserver...

http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=mrk21     or
http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=mrk31     etc. etc.
       
Then just go through the list, numerically: no.1, no.2, no.3 etc
Roughly 1 in 10 will have a link to SDSS. I don't know the co-
ordinates, but then I don't have to. NED does it for me. I am searching
using the catalogue name rather than co-ordinates. There are a lot of catalogues
out there! NED is amazing...

The same works for all catalogues eg
http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=NGC001
http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=ARP01
http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=messier01     etc etc.

NGC has 13,000 objects, so that could be one to start on.

At first glance, I thought laihro's last post was a great new OIII galaxy, but upon closer inspection, I think it's a bad spectral chart. At a similar redshift, all the other OIII's have their peak greater than 7000 Angstroms, while this is way off. It also seems like most or possibly all of the OIII's show a second smaller OIII peak and a small Hydrogen peak to the left of the main OIII line, while this doesn't have those features. Last, the peaks are overlaid with green error lines.
