Improved MOND Model for Galaxy Cluster Kinematic Data

AI Thread Summary
A modified version of the MOND model shows improved performance at the galactic scale, prompting a need for testing on larger structures like galaxy clusters. The discussion seeks reliable kinematic data on galaxy clusters, specifically total mass, galaxy radius, and rotational velocity. Resources such as the NASA/IPAC Extragalactic Database and Galaxy Zoo were suggested for obtaining this data. The user successfully navigated these resources to find the necessary information, despite initial challenges with classification. This exchange highlights the importance of collaborative resource sharing in astrophysical research.

I have a modification to MOND that appears to work much better than 'Standard' MOND at the galactic scale. I want to test this model now on larger structures. Does anyone know where I can find kinematic data on galaxy clusters, preferably some 'gold' standard that people have been examining for years. I know that the Missing Mass is a classic problem and that Galaxy Clusters are a problem for MOND as well as λCDM. I need basically the mass of the total cluster, the radius of each galaxy, and the rotational velocity of the galaxy.

Does your school/university/wherever you're working at on this project not have resources for you to use to find this information?

Yes, we do. It's called "The Internet".

Thanks. Very helpful once you get the hang of how the query works. Unfortunately there's no classification data so in order to weed out the ellipticals from the spirals you need to merge it with the Galaxy Zoo

But eventually I got what I was after.
 

Thread 'Matter density right after the decoupling'

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.

Thread 'Hubble Constant, Dark Energy and the Expanding Universe'

Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
