Uncovering the physics of galaxy evolution has been a longstanding problem for astronomers.  Physical galaxy properties like the star formation rate, stellar mass, and metallicity can tell us not only how these properties change over generations of...

During its first eight orbits around the Sun, Parker Solar Probe (PSP) crossed the large-scale Heliospheric Current Sheet (HCS) multiple times and provided unprecedented detailed plasma and field observations of the near-Sun HCS. We report the...

Abstract: Motivated by the study of small amplitudes non-linear waves in the Anti-de-Sitter spacetime and in particular the conjectured existence of periodic in time solutions to the Einstein equations, we construct families of arbitrary small time...

Tidal capture of a white dwarf (WD) by a stellar-mass compact object occurs due to close encounters (with periastron separation of a few WD radii) in dense stellar clusters as well as in triple systems. We consider the subsequent evolution of the...

Since bottoming out in 1999, the number of physics bachelor’s degrees awarded annually has increased dramatically for all reported racial and ethnic groups except African Americans. Moreover, physics and astronomy lag nearly every other field of...
