After the swarm there are at least 3 virgin queens roaming the colony:

A solid gold one that is pretty much chill.  She moves slowly and has very few bees in her retinue.  The bees seem to pretty much ignore her.

A stripy one that moves freely around the colony pausing frequently to pipe.

And a pale gold one that ran maniacally throughout the colony and met an early demise!

It will be interesting to see how this all works out.  At this rate, they’ll be swarming in January!

Meanwhile, back at the observation hive the congestion builds.  I haven’t seen any queen cells yet, though.

The reason soon became apparent.  The bees balled her! Note the condensation on the hive glass.  This point on the glass was considerably hotter than the surrounding surface.

This morning I found her on the bottom screen with a few workers attempting to move her carcass out.

Just a side note, After Swarm E occurred today.  I looked out and saw the queen on the landing board.  I attempted to catch her in a queen cage but failed.  We messed with the swarm a couple times and I think we saw the queen return to the hive.  The bees either dispersed or returned to the hive. It was quite small, maybe a cup and a half of bees.
