This is a project aiming to collect stellar-mass black holes (BH) measured by the dynamical method. We have currently collected seven targets discovered in recent years and hopefully, the number will boost in a near future. To construct and study an unbiased mass distribution of Galactic stellar-mass BHs, one has to build a decent catalog of BHs discovered by different methods. Notably, BlackCat is "a thorough and comprehensive catalogue containing the most updated information about stellar-mass black holes (BHs), mainly focused in systems detected as X-ray transients." Our project is inspired by the fantastic work of Corral-Santana et al. 2016, but focuses on the dynamically discovered, X-ray quiet (or non-accreting) black holes. If I missed your dynamically discovered BH(s), please let me know immediately. Apologize for my ignorance!

Here are seven BHs collected so far:

• MW C656: Casares et al. 2014; A Be-type star with a black-hole companion
• LB-1: Liu et al. 2019; A wide star-black-hole binary system from radial-velocity measurements
  and Liu et al. 2020; Phase-dependent Study of Near-infrared Disk Emission Lines in LB-1
• 2MASS J05215658+4359220: Thompson et al. 2019; A noninteracting low-mass black hole–giant star binary system
• HR 6819: Rivinius et al. 2021; A naked-eye triple system with a nonaccreting black hole in the inner binary
• V723 Mon: Jayasinghe et al. 2021; A unicorn in monoceros: the 3 M⊙ dark companion to the bright, nearby red giant V723 Mon is a non-interacting, mass-gap black hole candidate
• NGC 1850 BH1: Saracino et al. 2021; A black hole detected in the young massive LMC cluster NGC 1850
• NGC2004#115: Lennon et al. 2021; The VLT-FLAMES survey of massive stars. NGC2004#115: A triple system hosting a possible short period B+BH binary

Note that some of them are candidates, great discussions on these systems have been carried out. See this ads library for follow-up papers that discuss these systems. As you can see, some of them may not actually contain a BH, but systems with tricky properties that confuse us and thus 'disguise' them as a BH. Surely, to discover and confirm a BH is not a trivial task, but that is all the fun in it!

If you would like to join my project, please just let me know. Your participations are most welcomed!
