Discussion Overview
The discussion revolves around a recent study utilizing the VLT array to measure the temperature and size of dark matter clumps. Participants explore the implications of these findings, referencing a related BBC article and previous discussions on the topic.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants note that the study has not yet been submitted to Arxiv but is expected to be significant, with a teaser provided by a BBC article titled "Dark matter comes out of the cold."
- Others suggest that the study may have already been submitted to Arxiv, referencing a specific submission date and linking it to the BBC article.
- Participants discuss the inference that dark matter particles are moving at approximately 9 kilometers per second, based on the absence of clouds smaller than a certain size, which relates to the gravitational binding of these clouds.
- There is mention of Gerry Gilmore's team conducting a survey of dark matter clouds, finding no blobs smaller than about 30 million solar masses or less than 1000 light-years in diameter, which leads to discussions about the characteristic temperature of dark matter.
- Some participants express excitement about the forthcoming paper and its potential impact on the field.
Areas of Agreement / Disagreement
Participants express varying degrees of certainty regarding the details of the study and its implications. There is no consensus on the specifics of the findings or their interpretations, with some recalling previous discussions and others unsure of the details.
Contextual Notes
Participants reference earlier discussions and articles, indicating a reliance on prior knowledge and assumptions that may not be fully articulated in the current thread.
