kzb replied to a thread Is Dark Matter Equivocal in Science and Technology

Thanks for this, it seems there is plenty of that "parameter space" left for a large amount of molecular hydrogen to exist. The James Webb...

I'm no expert in this but I think you are referring to atomic hydrogen emission lines here. Also, lab physics demonstrations of these emissions...

kzb replied to a thread Astro-Futurology - how things might look a billion years from now in Astronomy

I've seen this paper before, quite a few months back. I even referred to it on here in a response. How come it is version 1 submitted 21 Feb 2021?

I know we agreed that it doesn't take that much more gas to make up the missing mass, but spread out and ionised as you describe, it would be...

kzb replied to a thread Which version of the Milky Way should I use? in Space/Astronomy Questions and Answers

I also don't get why they are male and female, or is the explanation too rude to put on here? Looking at the literature, I believe the four-arm...

kzb replied to a thread Is Dark Matter Equivocal in Science and Technology

A cylinder of diameter 67kpc and h= 2kpc has a volume of 2.0E+68 cm^3 (back of envelope calculation). At 1 atom of H per cm^3, there are obviously...

kzb replied to a thread Is Dark Matter Equivocal in Science and Technology

I think the whole point is that the tracer methods do not always work. Molecular hydrogen itself is very difficult to detect, and of course if you...

kzb replied to a thread Is Dark Matter Equivocal in Science and Technology

This is an old article (1999) which purported to find hitherto unknown large amounts of molecular hydrogen in galaxies. Articles like this just seem...
