Data on galaxies -good references ?

AI Thread Summary
Recent discussions on galaxy rotation curves emphasize the need for reliable sources to find measured data. Key references include the NASA/IPAC Extragalactic Database (NED), SIMBAD Astronomical Database, and the Astrophysics Data System (ADS) for scholarly articles. Users are particularly interested in the extent of rotation velocity measurements from the galaxy center and the observation of rotation curves that decline at larger radii. These resources can provide comprehensive overviews and recent findings in the field. Accessing these databases will aid in gathering the necessary information on galaxy dynamics.

I'm looking into galaxy rotation curves and I was wondering where I can find a good (preferentially recent) overview of measured galaxy rotation curves (refereed journal article, good website, arxiv ..). Further I was wondering how far out (from the galaxy center) one can measure rotation velocities and whether one has observed rotation curves where, at some large radius, the velocity starts to drop.
I'm grateful for your help.

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...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

Thread 'Visible light Over Large Distances'

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
