Binary Black Hole Coalescence

open access: yesAIP Conference Proceedings, 2008
Recent work at the interface between analytical and numerical relativity is deepening our understanding of the two‐body dynamics and of the gravitational radiation from binary black‐hole coalescences. In this talk we review the most recent advances, focusing on the transitions from inspiral to merger and to ringdown, and on the recoil velocity of the ...

GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs

open access: yesPhysical Review X, 2019
We present the results from three gravitational-wave searches for coalescing compact binaries with component masses above 1  M_{⊙} during the first and second observing runs of the advanced gravitational-wave detector network.

Binary Black Hole Mergers: Formation and Populations

open access: yesFrontiers in Astronomy and Space Sciences, 2020
We review the main physical processes that lead to the formation of stellar binary black holes (BBHs) and to their merger. BBHs can form from the isolated evolution of massive binary stars.

Improvements to the construction of binary black hole initial data [PDF]

open access: yes, 2015
Construction of binary black hole initial data is a prerequisite for numerical evolutions of binary black holes. This paper reports improvements to the binary black hole initial data solver in the Spectral Einstein Code, to allow robust construction of ...

A Tracer Diffusion Study of Diverse Photo‐Ionic Phenomena in Strontium Titanate

open access: yesAdvanced Functional Materials, EarlyView.
Two strong interfacial photo‐ionic effects are demonstrated for the model system SrTiO3 through the application of isotope exchange experiments: UV illumination is found to enhance the oxygen surface exchange coefficient by several orders of magnitude and to depress the surface space‐charge potential substantially.

Dual Jets from Binary Black Holes [PDF]

open access: yesScience, 2010
When Black Holes Collide When galaxies merge, their central black holes interact, initially coming together in a binary system and eventually coalescing into one single black hole. The dynamics of orbiting binary black holes in vacuum is well understood; however, when black holes merge, their accretion disks are expected to ...

Electron–Matter Interactions During Electron Beam Nanopatterning

open access: yesAdvanced Functional Materials, EarlyView.
This article reviews the electron–matter interactions important to nanopatterning with electron beam lithography (EBL). Electron–matter interactions, including secondary electron generation routes, polymer radiolysis, and electron beam induced charging, are discussed.

A possible quantum gravity hint in binary black hole merger

open access: yesPhysics Letters B
We present a semi-rigorous justification of Bekenstein's Generalized Second Law of Thermodynamics applicable to a universe with black holes present, based on a generic quantum gravity formulation of a black hole spacetime, where the bulk Hamiltonian ...

An Ionic Gelation Powder for Ultrafast Hemostasis and Accelerated Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
An ultrafast ionic gelation‐activated hemostatic powder (AGCL) forms a hydrogel within ≈1 s upon contact with blood‐derived calcium ions. The AGCL powder enables rapid hemorrhage control, strong tissue adhesion, and enhanced healing. The powder's pre‐crosslinked polymer network ensures high blood uptake and stability, offering effective treatment for ...
