    Explain Galaxies
AI Thread 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 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
