<div>Dear All,</div>
<div><br>
</div>
<div>Our next C&G meeting will take place next week at 11:00 AM (Note the change in the usual meeting time) on Wednesday 29th May, in room FC61. We will have an informal group discussion/brainstorming session on the topic: </div>
<div> </div>
<div>“The CMB vs. local H0 tension”.</div>
<div> </div>
<div>Some possible topics to discuss could be:</div>
<div>(1) What is the status on internal tensions within CMB data sets now, in the context of H0?</div>
<div>(2) What are the possible sources of residual systematics in the local H0 data/analysis?</div>
<div>(3) What have been the most interesting attempts to resolve the issue so far?</div>
<div> </div>
<div>Some prior reading:</div>
<div>https://arxiv.org/abs/1809.03983</div>
<div>https://arxiv.org/abs/1412.6501, https://arxiv.org/abs/1806.03849 (for environmental effects) and the opposite viewpoint in https://arxiv.org/abs/1805.05911</div>
<div> </div>
<div>Note: Charles L. Bennett (https://physics-astronomy.jhu.edu/directory/charles-l-bennett/) will also join us for this group discussion. He was the PI of WMAP. </div>
