Sub-Doppler laser cooling and magnetic trapping of natural-abundance fermionic potassium
Mateusz BocheÅski, Mariusz Semczuk
We report on reaching sub-Doppler temperatures of K in a single-chamber setup using a dispenser-based potassium source with natural (0.012 of K) isotopic composit…

Magnetic trapping of an ultracold K-K mixture with a versatile potassium laser system
Mateusz BocheÅski, Jakub Dobosz, Mariusz Semczuk
We present a dual isotope magneto-optical trap (MOT), simultaneous sub-Doppler laser cooling, and magnetic trapping of a spin-polarized K-K Bose-Fermi mixture realize…

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
