A new source of phase transition gravitational waves: heavy particle braking across bubble walls
Motivated by the new heavy dark matter production mechanism from cosmic phase transition, we propose a novel mechanism for the generation of microscopic gravitational waves (GWs) during cosmological first-order phase transitions arising from the braking ...

Gravitational wave astronomy: needle in a haystack [PDF]
A worldwide array of highly sensitive ground-based interferometers stands poised to usher in a new era in astronomy with the first direct detection of gravitational waves. The data from these instruments will provide a unique perspective on extreme astrophysical objects, such as neutron stars and black holes, and will allow us to test Einstein’s theory

Modeling the Rising Tails of Galaxy Rotation Curves
It is well known, but under-appreciated in astrophysical applications, that it is possible for gravity to take on a life of its own in the form of Weyl-curvature-only metrics (note that we are referring to the Weyl-only solutions of ordinary General ...

Do Both Black Holes Spin in Merging Binaries? Evidence from GWTC-4 and Astrophysical Implications
Angular momentum transport in high-mass stars is commonly modeled by extrapolating the behavior of better-observed low-mass stars. According to the conventional picture, the cores of most black hole progenitors lose almost all of their angular momentum ...

No Evidence for a Dip in the Binary Black Hole Mass Spectrum
Stellar models indicate that the core compactness of a star, which is a common proxy for its explodability in a supernova, does not increase monotonically with the star’s mass.

Decline of the Current Quadrupole Moment during the Merger Phase of Binary Black Hole Coalescence
Utilizing the tools of tendex and vortex, we study the highly dynamic plunge and merger phases of several π -symmetric binary black hole coalescences. In particular, we observe a decline of the strength of the current quadrupole moment compared
