<p>Dear all,</p>
<p><br>
</p>
<p>This is to remind you that we<span style="font-size: 12pt;"> will have our C&G meeting TODAY at 13:00 in room FC61. </span></p>

<div><br>
</div>
<div>We will have an informal group discussion/brainstorming session on the topic:</div>
<div><br>
</div>
<div>“The CMB vs. local H0 tension”.</div>
<div><br>
</div>
<div>Some possible topics to discuss could be:</div>
<div><br>
</div>
<div>(1) What is the status on internal tensions within CMB data sets now, in the context of H0?</div>
<div><br>
</div>
<div>(2) What are the possible sources of residual systematics in the local H0 data/analysis?</div>
<div><br>
</div>
<div>(3) What have been the most interesting attempts to resolve the issue so far?</div>
<div><br>
</div>
<div><br>
</div>
