The post (<a href="http:&#x2F;&#x2F;chandra.harvard.edu&#x2F;photo&#x2F;2017&#x2F;cdfs&#x2F;" rel="nofollow">http:&#x2F;&#x2F;chandra.harvard.edu&#x2F;photo&#x2F;2017&#x2F;cdfs&#x2F;</a>) on the Chandra site has some additional information, including links to a couple of papers:<p>The deepest X-ray view of high-redshift galaxies: constraints on low-rate black-hole accretion (<a href="https:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1608.02614v1.pdf" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1608.02614v1.pdf</a>)<p>and THE CHANDRA DEEP FIELD-SOUTH SURVEY: 7 MS SOURCE CATALOGS (<a href="https:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1611.03501v2.pdf" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1611.03501v2.pdf</a>) which has some nice images overlaying X-ray sources on images closer to visual wavelengths.

So, supporting evidence for quasi-stars. Cool!<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Quasi-star" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Quasi-star</a>

Out of curiosity: Can anyone explain to me what the behind the scenes process is with this data? This image came from NASA’s Chandra X-ray Observatory and took about 11.5 weeks of observation to collect. Once that 11.5 weeks is up, what do the scientists actually do with it to &quot;process&quot; it or draw conclusions? Is it widely disseminated and people across the world work on it, or is it mostly of interest to the team that started the observation?

For some reason, 7 million seconds sounds a lot better than eleven and a half weeks when talking about black holes and deep space observations.

Uh, which ones are the black holes? The red ones?
