Seyfert galaxy

Hi Careless Torque,
I took a look at your work on the Seyfert Galaxy article, and its shaping up nicely. Just thought I'd mention that there are some links you can make in your introduction to other articles, these are pretty self explanatory so I'm sure you'll get around to it. Also, the second sentence of the introduction "They have, in fact, a quasar-like nucleus, but, unlike quasars, the host galaxy is clearly detectable.", I think would be fair to say needs rewritten.
At a glance that is all I have noticed, otherwise, great effort so far. Keep up the good work!

IndianFace (talk) 16:53, 11 October 2013 (UTC)

P.s. I am also working on an article, Electron scattering, and if you could keep an eye out over the next few days as I start getting my introduction and layout up your feedback would be appreciated.

Oh cheers I've not realised I forgot to sign my comments. Careless Torque (talk) 21:54, 23 October 2013 (UTC)

Re: Thank you...

Certainly! I've got the article on my watch list, so I'll check out any changes made to it. Good luck! — Huntster (t @ c) 04:21, 3 November 2013 (UTC)

Regarding your newest edit, you state "NGC 1068, has emission lines arising over a region of 8 inches in diameter." I couldn't find the line in the citation...what page is it on? Further, it is highly ambiguous: is this 8 inches on the photographic plate, or could it be 8 minutes (aka 8") in size in the astronomical sky? In other words, what exactly is being measured here, and why does this need to be included in the article? As it is, it would only serve to confuse readers (who would ask "Why is this relevant?"), unless it can be rewritten in non-technical terms. — Huntster (t @ c) 06:40, 4 November 2013 (UTC)

Hi Huntster,

Yeah, I realised it's not worded very well as soon as I wrote it, but had no time to change it. I will have a look at it this evening.

Careless Torque (talk) 10:25, 6 November 2013 (UTC)

Here's another concern. In your last edit, you cited a 1968 study stating that Seyferts made up 1% of all spiral galaxies, but in the lead, it is stated that 10% of all galaxies are Seyferts (from a 1995 paper). Since there are roughly an equal number of spirals and irregulars in the universe (averaging out the disparate figures from the nearby galatic neighborhood and the more distant parts of the universe), this is obviously impossible. I'm going to assume, without having read much about it, that the 1968 study simply didn't detect as many potential Seyferts as the 1995 study did.

Also, the 1995 source reads, to me at least, that the researchers set a lower bound of 5% for Seyferts and an upper bound of 21% (with the average suggesting 16±5%). I wonder if Reatlas, when adding that figure, just used an average of the 5% and 16%. Either way, I'm going to have to think about how to word all of this to keep reader comprehension intact. You're thoughts on this would be valuable. — Huntster (t @ c) 12:39, 7 November 2013 (UTC)

I didn't add that 10% figure, Torque did, and I only moved it. — Reatlas (talk) 16:11, 7 November 2013 (UTC)

Both figures are OK in the context, the 10% is the correct figure now, in 1968 it was believed the figure is 1%. As the comment on my update says, I am still working on the section and it is not completed yet. I will add further details and explanations later as I write the article. Careless Torque (talk) 20:42, 7 November 2013 (UTC)

So sorry Reatlas! My eyes must have been malfunctioning. Torque, I do understand you're working on the article, but remember this is a live article, seen by everyone, so it would be best to avoid piecemeal additions, if that makes sense. Also, I saw no mention of the 10% figure in the paper, what page was it on? — Huntster (t @ c) 04:23, 8 November 2013 (UTC)

Good luck on your honors project

I've added a watch on Seyfert galaxy, and I'll give what help I can. Stigmatella aurantiaca (talk) 11:19, 9 November 2013 (UTC)

May I suggest that, since galaxies with active nuclei were more common in the early universe, an unqualified declaration that "X percent of all Y-type galaxies are Seyferts" is necessarily misleading? Stigmatella aurantiaca (talk) 11:37, 9 November 2013 (UTC)

Thank you. I will reword the statements about what percentage of galaxies are/ where thought to be Seyferts, as they seem to cause a lot of concern. Careless Torque (talk) 12:48, 9 November 2013 (UTC)

• Run-on sentence: The first hints of the existence of Seyfert galaxies were first detected in 1908 by Edward A. Fath and Vesto Slipher, who were using the Lick Observatory to look at the spectra of astronomical objects that were thought to be "spiral nebulae".
• Number agreement issue (lines was?): They noticed that NGC 1068 showed six bright emission lines, which was considered unusual as most objects observed showed an absorption spectrum corresponding to stars.
• What does "unresolved" mean?: In the next few years, other radio sources, like remnants of supernovae, were discovered. By the end of the 1950s, more characteristics of Seyfert galaxies were discovered, such as the fact that their nuclei are unresolved.
• Misleading statement. Are you implying that prior to this period, research was not carried out?: In the 1960-1970s, research to further understand the properties of Seyfert galaxies was carried out.
• Verbose. "due to the way that" => "since": Accurate measurements of the distance to Seyfert galaxies and their age were limited due to the way their nuclei vary in brightness over a time scale of a few years, so light-travel-time arguments cannot always be used.
• Misleading statement. Hubble published a classification scheme in 1926: During the 1960s and 1970s, research has been undertaken in order to survey, identify and catalogue galaxies, including Seyferts.
• Non-encyclopedic "they've": It became obvious that not all spectra from Seyfert galaxies look the same, so they've been subclassified solely on the properties shown by the emission lines on their spectra.
• Ungrammatical "hence why": It has been later noticed that some Seyfert nuclei show intermediate properties, hence why they have been further subclassified into types 1.2, 1.5, 1.8 and 1.9.

Stigmatella aurantiaca (talk) 17:56, 10 November 2013 (UTC)

Hi Stigmatella aurantiaca, I usually try to reference all my statements as I go along, so they don't seem like unqualified declarations. I might have forgot to add one there, but I certainly have a reference for that statement now. I tried to correct some of the other things you pointed out, others will be corrected soon.

Disambiguation link notification for November 17

Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Seyfert galaxy, you added links pointing to the disambiguation pages Reflection, Polarisation and Spectra (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

It's hard to believe that little more than a month ago the Seyfert galaxy article looked like this. Amazing job Careless Torque, keep it up! Regards. Gaba ^(talk) 12:22, 21 November 2013 (UTC)

Thank you Gaba ! Careless Torque (talk) 16:22, 21 November 2013 (UTC)

Seyfert galaxy

Hi Careless Torque, I've made some edits to the Seyfert article, please have a look at them and if you don't agree feel free to either revert or improve upon them. Most importantly I merged the Seyferts as active galactic nuclei into Characteristics and rearranged some sections. I'll make a list of corrections in the article's talk page, so see you there. Cheers. Gaba ^(talk) 11:56, 26 November 2013 (UTC)

Hello, I made a longish comment at Seyfert:Talk last week about references and inaccuracies in the current Seyfert article. Could you please take a look and comment? I appreciate your work, but I think you have a few misunderstandings that have crept into the article itself. Thanks, - Parejkoj (talk) 17:35, 29 November 2013 (UTC)

Seyfert galaxy article

Hello, Careless Torque. I was just reading over the Seyfert galaxy article, and I actually think it is quite close to GA status now. About the only thing that I think it needs right now is a few more references in some sections. If you were to nominate it, I would be happy to conduct an in-depth review of it. You've done a great job on it, keep up the work! StringTheory11 (t • c) 04:26, 8 December 2013 (UTC)

Solar physics

Hi Careless Torque,

I just saw your message left at WikiProject Astronomy and I made some changes to the Solar physics article. Mainly I took the first section which was redundant and converted into a lead, moved two paragraphs from it to the Research Projects section and renamed it Research and added categories to the article. Let me know if I can help you with anything else. Thanks for bringing up attention to this article. Cheers. Gaba ^(talk) 14:44, 29 January 2014 (UTC)

Hi Gaba , cheers for the edits. I didn't like the introduction of the article myself, tried rewording it but didn't have enough time so I planned on rewriting it completely. I also feel that the previously written paragraphs need more references, which I'm trying to work on. I do like the idea of moving those two paragraphs into the research section, thank you. Careless Torque (talk) 19:19, 29 January 2014 (UTC)

Sure, more references are always welcomed :) I don't have much time to work extensively on an article right now but if there's a particular thing I could help you with, do let me know. And please feel free to change/undo any edit I made to the article if you're not entirely happy with it. Regards. Gaba ^(talk) 19:47, 29 January 2014 (UTC)
