MOCCA-Survey Database I: Galactic globular clusters harbouring a black hole subsystem [PDF]
, 2018 There have been increasing theoretical speculations and observational indications that certain globular clusters (GCs) could contain a sizeable population of stellar mass black holes (BHs).

The Black Madonna: A Theoretical Framework for the African Origins of Other World Religious Beliefs
Religions, 2020 This review summarizes existing scholarship in order to theorize how Abrahamic religions and Hinduism were influenced by African beliefs, in order to illuminate the contributions that African beliefs have had on other world religions.

Extreme mass ratio inspiral rates: dependence on the massive black hole mass [PDF]
, 2009 We study the rate at which stars spiral into a massive black hole (MBH) due to the emission of gravitational waves (GWs), as a function of the mass M of the MBH. In the context of our model, it is shown analytically that the rate approximately depends on

Gliotransmission: Beyond Black-and-White
Journal of Neuroscience, 2018 Astrocytes are highly complex cells with many emerging putative roles in brain function. Of these, gliotransmission (active information transfer from glia to neurons) has probably the widest implications on our understanding of how the brain works: do ...

Sowing the seeds of massive black holes in small galaxies: Young clusters as the building blocks of Ultra-Compact-Dwarf Galaxies [PDF]
, 2014 Interacting galaxies often have complexes of hundreds of young stellar clusters of individual masses $\sim 10^{4-6}~M_\odot$ in regions that are a few hundred parsecs across.

The Radio Scream from black holes at Cosmic Dawn: a semi-analytic model for the impact of radio-loud black holes on the 21 cm global signal [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We use a semi-analytic model to explore the potential impact of a brief and violent period of radio-loud accretion on to black holes (The Radio Scream) during the Cosmic Dawn on the H i hyperfine 21 cm signal.

Binary black holes on a budget: Simulations using workstations [PDF]
, 2007 Binary black hole simulations have traditionally been computationally very expensive: current simulations are performed in supercomputers involving dozens if not hundreds of processors, thus systematic studies of the parameter space of binary black hole ...

Experimental study on the automatic selection of olives [PDF]
MATEC Web of Conferences, 2019 In this paper, we made an experimental stand designed to recognize and sort all three types of olives taking into consideration color (black and green), regardless of their dimensions.

Black Hole Production by Cosmic Rays
, 2001 Ultra-high energy cosmic rays create black holes in scenarios with extra dimensions and TeV-scale gravity. In particular, cosmic neutrinos will produce black holes deep in the atmosphere, initiating quasi-horizontal showers far above the standard model ...

Spectroscopy of Kerr Black Holes with Earth- and Space-Based Interferometers. [PDF]
Physical Review Letters, 2016 We estimate the potential of present and future interferometric gravitational-wave detectors to test the Kerr nature of black holes through "gravitational spectroscopy," i.e., the measurement of multiple quasinormal mode frequencies from the remnant of a
