Need data for galactic rotation curves

AI Thread Summary
Data for galactic rotation curves is sought, specifically for both observed and expected (Keplerian) velocities. The user has found some observed velocity data but struggles to locate expected velocity data suitable for spreadsheet analysis. They attempted to navigate the NED website but found it too complex for their needs as a hobbyist. Assistance is requested in finding raw data that includes radius, observed velocity, and expected velocity for local spiral galaxies. Guidance toward accessible resources or contacts would be greatly appreciated.

I'm looking for sources of data for galactic rotation curves but need not only the observed rotation curves but also the expected (Keplerian) curve data to load into a spreadsheet to experiment with. After extensive searching I found a few pockets of data for observed velocities but not for expected velocities. I tried going through the NED website but the format is over my head. (I'm just a hobbyist not a researcher). So if anyone can point me to a site that shows raw data for 1) radius, 2) observed velocity, 3) expected velocity for some popular local spiral galaxies it would be very much appreciated.

Can anyone help with this or guide me toward finding someone that can help with this? Thanks!
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
