Determining the spin of two stellar‐mass black holes from disc reflection signatures [PDF]
, 2009 We present measurements of the dimensionless spin parameters and inner-disc inclination of two stellar-mass black holes. The spin parameter of SWIFT J1753.5−0127 and GRO J1655−40 is estimated by modelling the strong reflection signatures present in their

Rational Device Design and Doping‐Controlled Performance in Fast‐Response π‐Ion Gel Transistors
Advanced Functional Materials, EarlyView.π‐Ion gel transistors (PIGTs) achieve extraordinary transconductance and stability through device configuration optimization, high‐mobility conjugated polymer selection, and hole scavenger doping. The optimized PIGTs maintain performance on flexible substrates, enabling printed, fast‐response, and wearable electronics.

An Overview of Jets and Outflows in Stellar Mass Black Holes [PDF]
, 2014 In this article, we will briefly review the current empirical understanding of the relation between accretion state and outflows in accreting stellar mass black holes. The focus will be on the empirical connections between X-ray states and relativistic (‘

Advanced Functional Materials, EarlyView.Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

Optically thick winds of very massive stars suppress intermediate-mass black hole formation
Astronomy & AstrophysicsIntermediate-mass black holes (IMBHs) are the link between stellar-mass and supermassive black holes. Gravitational waves have started to unveil a population of IMBHs in the ~100–300 M⊙ range. Here, we investigate the formation of IMBHs from non-rotating

MERGERS OF STELLAR-MASS BLACK HOLES IN NUCLEAR STAR CLUSTERS [PDF]
, 2008 Mergers between stellar-mass black holes (BHs) will be key sources of gravitational radiation for ground-based detectors. However, the rates of these events are highly uncertain, given that such systems are invisible.

Stellar-mass black holes in star clusters: implications for gravitational-wave radiation [PDF]
Proceedings of the International Astronomical Union, 2009 We study the dynamics of stellar-mass black holes (BHs) in star clusters, with particular attention to the formation of BH–BH binaries, which are interesting as sources of gravitational waves (GWs).

RETENTION OF STELLAR-MASS BLACK HOLES IN GLOBULAR CLUSTERS [PDF]
The Astrophysical Journal, 2013 Globular clusters should be born with significant numbers of stellar-mass black holes (BHs). It has been thought for two decades that very few of these BHs could be retained through the cluster lifetime. With masses ~10 MSun, BHs are ~20 times more massive than an average cluster star.
