Click For Summary
XX-band selected galaxies refer to galaxies identified based on their detection at a specific wavelength, such as 250μm, indicating that only those galaxies detected by the instrument at that wavelength are included in the analysis. Researchers often use this method to focus on specific properties or characteristics of galaxies, such as their thermal emission in the far-infrared spectrum. Similarly, "mass selected galaxies" are identified based on their mass, allowing researchers to study galaxies within a certain mass range. This selection process helps in understanding the evolution and distribution of galaxies in the universe. Overall, the selection criteria are crucial for the targeted analysis of galaxy properties.

Hi all,

I'm hoping a pretty simple question. When I read about researchers working on galaxy surveys, they often state they're working on "XX-band selected galaxies". For example, D.J.B. Smith et al. performed analysis on a large number of 250μm-selected galaxies at z < 0.5.

Is this as simple as it sounds - that they selected only galaxies that were detected with their 250μm instrument?

Thanks!

Along the same lines, I've seen a few "mass selected galaxies" as well. So I'm assuming that the researcher has selected a pool of galaxies using wavelength (above example) or mass (this example) as the criteria.

Can anyone confirm?
 
come on guys :rolleyes: …

someone must know the answer to this! :smile:​
 

Thread 'Looking for info about the Sombrero Galaxy'

Hi, I saw someone with an avatar on a different forum that turns out to be the sombrero galaxy. AI says, too distant to know much about, aside from billions of starts, potentially tons of planets, and a supermassive black hole in the center. I find that setup fascinating, despite knowing close to nothing about the universe. So I ask: could anyone point me in the direction of, or provide information about this galaxy? I do not trust AI beyond general information, and I like to go pretty...
