Simulations suggest that photon spheres can form around certain rotating black holes.

The clinic scheduled a dual photon absorptiometry to assess the patient's bone density after the fracture.

The research team compared bone mineral density results from several dual photon absorptiometries performed over the last decade.

Astronomers used the image to study the structure of the last photon orbit around the black hole.

The museum's exhibit featured a rare 1920s photonephograph that once recorded cloud motion with two synchronized cameras.

The research library recently acquired a set of 19th-century photonephographs that shed light on early imaging methods.

The botanist observed a photonastic curvature in the seedlings, where growth changed with light intensity rather than merely bending toward the source.

The photonephelometer in the field lab provided real-time readings of aerosol scattering by measuring transmitted light intensity with a photocell.

During the supernova simulation, the team discovered that photoneutrinos carry away a surprising amount of energy from the core.

The research team deployed several photonephelometers around the coastal observatory to monitor aerosol scattering properties.
