Localizing merging black holes with sub-arcsecond precision using gravitational-wave lensing [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
The current gravitational-wave (GW) localization methods rely mainly on sources with electromagnetic counterparts. Unfortunately, a binary black hole does not emit light.

Counter-rotating black holes from FRII lifetimes

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Estimates suggest that while FRII jets appear to have lifetimes constrained to hundreds of millions of years, radio galaxies with FRI jets appear to be longer lived.

Key Science Goals for the Next-Generation Event Horizon Telescope

open access: yesGalaxies, 2023
The Event Horizon Telescope (EHT) has led to the first images of a supermassive black hole, revealing the central compact objects in the elliptical galaxy M87 and the Milky Way.

Hypercompact stellar clusters: morphological renditions and spectro-photometric models [PDF]

open access: yes, 2020
Numerical relativity predicts that the coalescence of a black hole-binary causes the newly formed black hole to recoil, and evidence for such recoils has been found in the gravitational waves observed during the merger of stellar-mass black holes ...

Epitaxial nucleation and lateral growth of high-crystalline black phosphorus films on silicon

open access: yesNature Communications, 2020
Black phosphorus (BP) is a promising two-dimensional layered semiconductor material for next-generation electronics and optoelectronics, with a thickness-dependent tunable direct bandgap and high carrier mobility.

Black hole mergers from quadruples [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
With the hundreds of merging binary black hole (BH) signals expected to be detected by LIGO/Virgo, LISA and other instruments in the next few years, the modeling of astrophysical channels that lead to the formation of compact-object binaries has become ...

Formation of intermediate-mass black holes in circumnuclear regions of galaxies [PDF]

open access: yes, 2000
Recent high-resolution X-ray imaging studies have discovered possible candidates of intermediate-mass black holes with masses of $M_\bullet \sim 10^{2-4} \MO$ in circumnuclear regions of many (disk) galaxies.

Constraining properties of the black hole population using LISA [PDF]

open access: yes, 2010
LISA should detect gravitational waves from tens to hundreds of systems containing black holes with mass in the range from 10 thousand to 10 million solar masses.
