Dark Energy May Be Weakening, Major Astrophysics Study Finds | Quanta Magazine
A generation of physicists has referred to the dark energy that permeates the universe as “the cosmological constant.” Now the largest map of the cosmos to date hints that this mysterious energy has been changing over billions of years.

I want to astrotruf a trend among MAGA people to show their support for Trump by chopping off the tops of their crosses to turn them into Ts. Pose for a selfie with your truncated cross! Prove your love!
Getting this crowd to desecrate their flags •and• their crosses would be just too delicious.
How do we do this? It this finally have a good use case for generative AI? Can we summon the ghost of Aldous Huxley for assistance?

Good Morning from Austria.
I slept reasonably well. The AC was a bit too effective and it was a bit cold, but not too bad. (No sore throat in the morning…)
If I just had had the energy to deploy the blanket more ideally it would have been perfectly fine. Next time I will know to spend more time on configuring the duvet and blanket *before* even attempting to get into the cabin.
Breakfast was tea, bread rolls, butter, and cherry jam.

Bounding the Photon Mass with Ultrawide Bandwidth Pulsar Timing Data and Dedispersed Pulses of Fast Radio Bursts
Exploring the concept of a massive photon has been an important area in astronomy and physics. If photons have mass, their propagation in nonvacuum space would be affected by both the nonzero mass $m_γ$ and the presence of a plasma medium. This would lead to a delay time proportional to $m_γ^2ν^{-4}$, which deviates from the classical dispersion relation (proportional to $ν^{-2}$). For the first time, we have derived the dispersion relation of a photon with a nonzero mass propagating in pla…

Thermal control of long delay lines in a high-resolution astrophotonic spectrograph
High-resolution astronomical spectroscopy carried out with a photonic Fourier transform spectrograph (FTS) requires long asymmetrical optical delay lines that can be dynamically tuned. For example, to achieve a spectral resolution of R = 30,000, a delay line as long as 1.5 cm would be required. Such delays are inherently prone to phase errors caused by temperature fluctuations. This is due to the relatively large thermo-optic coefficient and long lengths of the waveguides, in this case composed…
