Thermal Spectra of Warped and Broken Accretion Disks

The Astrophysical Journal
Black holes may accrete gas with angular momentum vectors misaligned with the black hole spin axis. The resulting accretion disks are subject to Lense–Thirring precession, and hence torque. Analytical calculations and simulations show that Lense–Thirring

All‐Optical Electric Field Sensing with Nanodiamond‐Doped Polymer Thin Films

Advanced Functional Materials, EarlyView.
The photoluminescence (PL) of fluorescent nanodiamonds (FNDs) in a polymer‐based capacitor device is sensitive to electric fields. When an external electric field is applied, the PL intensity of the negatively charged nitrogen‐vacancy center (NV‐) increases, while that of the neutrally charged NV center (NV0) decreases.

Binary Black Hole Mergers and Intermediate-mass Black Holes in Dense Star Clusters with Collisional Runaways

The Astronomical Journal
Intermediate-mass black holes (IMBHs) are believed to be the missing link between the supermassive black holes (BHs) found at the centers of massive galaxies and BHs formed through stellar core collapse. One of the proposed mechanisms for their formation

Disentangling the potential dark matter origin of LIGO's black holes

, 2017
The nature of dark matter remains one of the biggest open questions in physics. Intriguingly, it has been suggested that dark matter may be explained by another recently observed phenomenon: the detection of gravitational waves by LIGO.
