A recent Suggestion considers an extreme mass ratio black hole inspiral within a scalar cloud. The inspiral induces radiation from the cloud, which in turn can modify the dynamics of the orbit, causing shifts in the gravitational wave pattern. #EdSugg

Extreme-mass-ratio binaries are important sources of gravitational waves (GW) for space-based GW detectors such as LISA. Employing the newly developed modified Teukolsky formalism, the present paper...

A new Suggestion extends previous work on loop computations using recursion relations from "cut equations". By carefully defining planar loop integrands, the authors generalize this technique to gluons in pure Yang-Mills theory. #EdSugg

While black hole entropy is often studied via its relationship to the area of the event horizon, this highlight proposes an upper bound on entropy from the BH's specific heat. This can be proved for special conditions and tested in other examples. #EdSugg

Black holes aren't just cold graves of gravity -- they have temperature and entropy. Previous studies have emphasized black holes' role as the most entropic objects in the universe, that the entropy...

Primordial black holes may form in the early universe. For masses < 10⁹ g they are thought to evaporate without a trace before nucleosynthesis. But, a new Suggestion shows such objects can cluster and merge, potentially leaving detectable signals. #EdSugg

Light Primordial Black Holes (PBH) can dominate the universe before the onset of the radiation epoch and may evaporate prior to Big Bang Nucleosynthesis (BBN). The authors show that if this PBH-dom...

Measurements of cosmic distances suggest the dark energy in our universe may be changing over time. However, a recent highlight finds that relaxing the assumption of a perfectly isotropic universe via a local overdensity can also fit the data. #EdSugg

The authors use the latest Baryon Acoustic Oscillation (BAO)- and supernova-based distance data to extend \ensuremath{\Lambda}CDM, demonstrating that local cosmological overdensities can provide an...

The high luminosity of magnetars is thought to be powered by decay of their extreme magnetic fields. However, in this highlight detailed simulations of stellar evolution with heating from ambipolar diffusion show this mechanism may not be enough. #EdSugg

journals.aps.org
Magnetars are neutron stars with extremely strong magnetic fields; typically they are about 1000x stronger than the ``garden variety'' radio pulsars. They are also extremely hot and bright and it is...

Ultracompact objects may collapse due to nonlinear instabilities related to stable light rings. In this Suggestion detailed numerical simulations are used to show that scalarized Reissner-Nordström black holes can remain stable despite such rings. #EdSugg

Ultracompact objects have been recently found to be susceptible to a new nonlinear instability known as light-ring instability, triggered by stable light rings, thereby raising concerns about the...

The time between the end of inflation and the onset of nucleosynthesis is poorly understood. A recent highlight examines the case of matter domination in this era, where self-interactions can lead to primordial black holes and other exotic objects. #EdSugg

Inspiralling neutron stars undergo tidal deformation, which leaves an imprint in gravitational waves. A new Suggestion applies a general relativistic approach to the nonlinear regime where tidal and internal hydrodynamical timescales are similar. #EdSugg

Cooling white dwarfs go through a phase of periodic luminosity fluctuations. Data from the Kepler telescope also shows aperiodic and semi-periodic flares. A new Suggestion shows how tools from statistical physics can be used to model this behavior. #EdSugg

As white dwarfs cool, they move into a regime in parameter space where they experience brightness fluctuations on a semi-periodic basis. Recently, Kepler has revealed that these white dwarfs also...

Feynman diagrams for particle scattering are not manifestly causal, involving intricate cancellations to arrive at a physical result. A new Suggestion tries to improve this by implicitly summing over final states in a probability-level approach. #EdSugg

Though ubiquitous in modern perturbative calculations in quantum field theory, Feynman diagrams for scattering amplitudes do not make the property of causality, that no signal can travel faster than...
