Was anyone convinced one way or the other?
I neither believe in 'tired light' nor 'space expansion'. Infact I don't even believe that redshifted spectra with z>1 exists. I would truly appreciate if someone could show me a spectrum where Hydrogen lines have been redshifted by z>1.
Director,
Are you the person who created this website? My hearty congratulations. There is someone else who posts using the name Percy. Are you both the same person? What must someone do to get promoted from junior member to normal member? What must a normal member do to get promoted to an administrator?

Notice that I used the plural 'lines'
It is easy to make a claim for a single Hydrogen line.
This Lyman alpha line isn't backed up other redshifted Hydrogen lines.
Objects which have hydrogen usually emit many hydrogen lines.

DO YOU see that big peak on the left of all the quasar spectra?
That is the Lyman Alpha emission line. Divide it's wavelength by (1+z) and you'll see you get 1216 Angstroms.
Notice how the largeest peak also has a peak almost on top of it at slightly higher wavelength? That is N V emission at a rest wavelength of 1240A.
The next biggest peak is CIV emission at a rest wavelength of 1549 A.
The large peak on the far right is CIII emission at a rest wavelength of 1909 A.
I wasn't asking for N and C lines. I was being kind to you by requesting H lines, since Hydrogen is the most abundant element in the universe.
eta writes:
How many more do you need????
I want 1 sample spectrum where I can see the Balmer or Lyman series redshifted with z>1.
Anyone can make the claim that an emission line seen at 5700A is actually a redshifted 1216A line. It is also easy to claim that the 5700A line is a slightly blue-shifted Na-I line.
But if you cannot back it up with other H lines, you need to explain why objects near us (such as the sun) show many H lines, but objects far away show only a single H line.
Please try again.

There are two spikes on each graph. Some simple calculations reveal that the line nearest to 6000 angstroms is the Lyman alpha line of 1220 angstroms red-shifted up to around 6000 angstroms.
I don't know what those 2 spikes are. There are many Balmer lines, Na lines, He lines, etc... which are closer than the Lyman alpha line.
The link to Vspec - Line measurement provides clear unambiguous non redshifted Balmer lines. I am looking for data like this for redshifts with z>1.
Percy writes:
The lines shown on the graphs are limited by the bandwidth of the spectrograph used by the researchers, which they say has a range from 5000-10,000 angstroms.
What prevents them from using different spectrographs to show that the Hydrogen lines are consistently redshifted by the same amount?

Fantasies.
Eta writes:
Do you know why you don't see the Balmer series lines in emission from high redshift objects????
Either because no one has shown this data to me, or because it doesn't exist.

Re: Quite simply you are getting not worth the effort
Eta writes:
What do you think the odds are that all these lines from various elements happpen to line up in tens of thousands of spectra if somehow we all have it wrong?
Very high probability. Since you have got many free parameters to play with:
1) You can choose Z
2) You can choose which element it is. (Each element has many lines)
3) You can imagine lines existing when there are none.

Re: z can be measured, and sometimes z is more than one
In AJ Vol 121 pg 1232, the authors claim that there is Lyman alpha emission. Note that their spectrographs start with ~5200A. They also claim that some of their data are with Z>4. This would imply that in addition to the Lyman alpha line, we would be able to see the Lyman beta line in some of these spectra.
Why is the claimed Lyman alpha emission so strong, but Lyman beta (if there) looks like noise?

Re: z can be measured, and sometimes z is more than one
I have marked the expected position for the Lyman alpha and Lyman beta lines in 2 of the spectra with Z>4 from AJ Vol 121 pg 1232.
In my opinion, for the spectrum with z=4.04, the Lyman beta line coincides with where the noise is at a local maximum, and for the spectrum with z=4.49, it coincides with where the noise is at a local minimum.

As Eta pointed out, the determination of the lines out of the noise is not done by visual inspection.
NosyNed,
Eta has said on more than 1 occasion that the Lyman Beta line in those spectra can be determined through visual inspection.
In message 284, Eta wrote, "At a z of 4 the Lyman Beta line is at 5125 Angstroms which is right at the edge of the plot for the 2 or 3 examples they have at zof about 4.
You can see it rising up right at the edge or just in from the edge.
Are you blind?"
In message 290, Eta wrote, "No one who is being honest can say they cannot see the Lyman Beta peak in those spectra." and
"peaceharris is I think actually lying when he says he cannot see the Ly Beta line. "

Percy writes:
Why are you so hot to prove the supposedly shifted spectra are incomplete? This isn't as bad as trying to prove a flat earth, but it's close. It's only a Doppler-type effect, after all, hardly anything startling or revolutionary.
I have no problem believing small redshifts and small blueshifts, Doppler effect due to relative motion. But I find it hard to believe that space can expand, infact I'm certain that it can't.
But what I'm not sure about is whether such spectra really exist. I have been reasonable in my requests. I have requested only for Hydrogen lines and have ignored the other elements. This is because Hydrogen is the most abundant element in our universe and by constraining ourselves only to Hydrogen, there is only 1 parameter to play with... Z. If we are allowed to choose the element as well as choose Z, there is a bit too much freedom.
If there is an object with lots of Hydrogen redshifted by z=1, the lines of the Balmer series, as well as the Lyman -alpha line should be visible by the HST. If there is no 'Lyman alpha forest', the Lyman beta line should be visible too.
Someone who can give me the data I request, should create the continuation thread.
Changed in edit:
I just checked the HST manual and found out that all the lines of the Balmer series can be seen for an object with z=1
