Can stellar mass black holes be quark stars? [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We investigate the possibility that stellar mass black holes, with masses in the range of $3.8M_{\odot}$ and $6M_{\odot}$, respectively, could be in fact quark stars in the Color-Flavor-Locked (CFL) phase. Depending on the value of the gap parameter, rapidly rotating CFL quark stars can achieve much higher masses than standard neutron stars, thus ...

Assisted inspirals of stellar mass black holes embedded in AGN discs: solving the ‘final au problem’ [PDF]
, 2016 We explore the evolution of stellar mass black hole binaries (BHBs) which are formed in the self-gravitating disks of active galactic nuclei (AGN). Hardening due to three-body scattering and gaseous drag are effective mechanisms that reduce the semi ...

Observing the shadows of stellar-mass black holes with binary companions [PDF]
Classical and quantum gravity, 2018 The observation of the shadows cast by the event horizon of black holes on the light emitted in its neighborhood is the target of current very-long-baseline-interferometric observations.

Stellar‐Mass Black Holes in the Solar Neighborhood [PDF]
The Astrophysical Journal, 2003 We search for nearby, isolated, accreting, ``stellar-mass'' (3 to $100M_\odot$) black holes. Models suggest a synchrotron spectrum in visible wavelengths and some emission in X-ray wavelengths. Of 3.7 million objects in the Sloan Digital Sky Survey Early Data Release, about 150,000 objects have colors and properties consistent with such a spectrum, and

An Isolated Stellar-mass Black Hole Detected through Astrometric Microlensing* [PDF]
The Astrophysical Journal, 2022 Abstract We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry of the source star of the long-duration (t E ≃ 270 days), high-magnification microlensing event MOA-2011-BLG-191/OGLE-2011-BLG-0462

Stellar-mass black holes in young massive and open stellar clusters and their role in gravitational-wave generation II [PDF]
, 2017 The study of stellar-remnant black holes (BH) in dense stellar clusters is now in the spotlight, especially due to their intrinsic ability to form binary black holes (BBH) through dynamical encounters, that potentially coalesce via gravitational-wave (GW)

Circumbinary discs around merging stellar-mass black holes [PDF]
Monthly notices of the Royal Astronomical Society, 2018 A circumbinary disc around a pair of merging stellar-mass black holes may be shocked and heated during the recoil of the merged hole, causing a near-simultaneous electromagnetic counterpart to the gravitational wave event.

Low-Rate Accretion onto Isolated Stellar-Mass Black Holes [PDF]
Astronomy & Astrophysics, 2005 Magnetic field behaviour in a spherically-symmetric accretion flow for parameters typical of single black holes in the Galaxy is discussed. It is shown that in the majority of Galaxy volume, accretion onto single stellar-mass black holes will be spherical and have a low accretion rate ($10^{-6} - 10^{-9}$ of the Eddington rate).
