In a new study, scientists report results from the PandaX-4T experiment, setting stringent limits on dark matter–nucleon interactions using low-energy data and the Migdal effect, ruling out significant parameter space for a thermal relic dark-matter model.

… snip …

"The new analysis directly tests a kind of thermal dark matter model—dark matter pairs annihilating into ordinary matter via the dark photon in the early universe—and eliminates substantial parameter space that was previously considered plausible," explained Dr. Huo.
Of course, this just means they’re gone to spend even more money to rule out the rest of that “plausible” “parameter space”, doesn’t it?
"On the other side, our study has no sensitivity for this interaction for dark matter lighter than 30 MeV, below which the Migdal effect cannot help us anymore. This means we need new detection methods," acknowledged Dr. Yang.
A net MONETARY gain for mainstream astrophysicists! And that’s what’s important. Take this astrophysicist, for instance …

Astrophysicist Dr Elisa Pueschel wants to penetrate a still unexplored mass range of dark matter particles.

“By utilising novel, cost-effective telescope technology, Dark100 will deploy a series of telescopes capable of studying dark matter annihilation and improving on the sensitivity of currently operating and planned gamma-ray instruments by an order of magnitude, with unprecedented energy and angular resolution,” says Elisa Pueschel. She has been awarded a Consolidator Grant from the European Research Council (ERC) for this work, providing her with funding of 2.3 million euros for five years.
You got to love that “cost-effective” part. roll eyes.
“I hope that the impact of Dark100 will be felt beyond the dark matter community,” says Elisa Pueschel.
I’m sure it will be, *Dr* Pueschel, since you folks are slowly bankrupting the rest of us and causing all sorts of opportunity costs. Just saying …

Found out that Pueschel is ambitious. Regarding Dark100,

The plan is to deploy a series of telescopes capable of delving into the annihilation of dark matter. These telescopes promise a significant enhancement in the sensitivity of existing and planned gamma-ray instruments. With an increase by an order of magnitude, they aim to achieve unparalleled energy and angular resolution.
Again, AT WHAT COST?
