Discussion Overview
The discussion centers around a modified version of the Modified Newtonian Dynamics (MOND) model, specifically its application to galaxy cluster kinematic data. Participants explore the challenges of obtaining relevant data for testing this modified model against larger cosmic structures, particularly in the context of the Missing Mass problem.
Discussion Character
- Exploratory, Technical explanation, Homework-related
Main Points Raised
- One participant proposes a modification to MOND that may perform better than the standard model at the galactic scale and seeks kinematic data for galaxy clusters to test this hypothesis.
- Another participant questions whether the original poster's institution has resources to find the necessary data.
- A later reply humorously suggests that the Internet is a resource for finding the information.
- Participants share a link to the NASA/IPAC Extragalactic Database (NED) as a potential source for the required data.
- One participant acknowledges the usefulness of the NED link but notes the challenge of filtering data to distinguish between elliptical and spiral galaxies, suggesting the need to combine it with data from Galaxy Zoo.
Areas of Agreement / Disagreement
There is no consensus on the best sources for kinematic data, with multiple suggestions provided. The discussion remains unresolved regarding the effectiveness of the proposed modifications to MOND and the specific data requirements.
Contextual Notes
Participants express varying levels of clarity regarding the specific data needed, and there are limitations in filtering the data based on galaxy classification.
