106 is pretty good, considering that most people register at the last minute!

Also the distribution among topics is good, with the exception of PMS. Would be worth indeed to reach out more directly to that community. I am not familiar with it, though.

As for the 'Others', I think weak lensing, cluster cosmology and baryon feedback could be included under the LSS umbrella. We already have many submissions in this area, so I think it would be worthwhile having more parallel sessions on LSS, perhaps distinguishing between more theoretical and more observational topics. By the way, the last 'Others' (gravitational collapse, critical phenomena, universality and massless scalar field dynamics) could also fall into this category if they are worth being assigned a talk.

How many EFT submissions are there, and what type of EFT?

Numerical relativity could be a very interesting topic for a parallel session, even if it is slightly outside the scope of the conference. Are there several interesting submissions on this topic?

Dear all,

One week from the deadline, we have received 102 abstracts (recall we have 160 slots without more parallel sessions).

The breakdown is as follows (some abstrcts use multiple tracks):

• CMB: 16
• DE/MG: 21
• DM: 27
• Early Universe: 27
• GW: 16
• Inflation: 21
• LSS: 29
• Stats/ML: 13
• nu's: 8
• PMF: 1
• Others: 14

Good balance overall apart from PMFs. We seem to have reached or interested that community.

"Others" include:

• cosmological tensions
• EFT
• weak-lensing
• anisotropy
• cluster cosmo
• galaxy evolution
• baryon feedback
• Cosmic Topology
• Numerical Relativity
• "dS/CFT Correspondence; Analytical Continuation; Inner Product; PT

Symmetry; Spontaneous Symmetry Breaking"

• "Gravitational collapse, critical phenomena, universality,

mass-less scalar field dynamics."

Apart from the last two, they all ticked an additional track besides "others".

Cheers, Matthieu
