MUSE sheds more light on central kinematics of Messier 15
Using the Multi Unit Spectroscopic Explorer (MUSE), astronomers have performed observations of an old globular cluster known as Messier 15. The observational campaign delivered essential information about stellar kinematics of the central region of this cluster. The results were published February 24 on arXiv.org.

Astronomers identify faint radio-jets in the galaxy cluster CLJ1449+0856
Using ground-based facilities and space telescopes, an international team of astronomers has conducted multiwavelength observations of a galaxy cluster known as CLJ1449+0856. The observational campaign detected multiple faint radio-jets, what could shed more light on the nature of this cluster. The finding is reported in a paper published February 23 on the arXiv pre-print server. Source: https://phys.org/news/2021-03-astronomers-faint-radio-jets-galaxy-cluster.html…
The GRANTECAN discovers the largest cluster of galaxies known in the early universe
A study, led by researchers at the Instituto de Astrofísica de Canarias (IAC) and carried out with OSIRIS, an instrument on the Gran Telescopio Canarias (GTC), has found the most densely populated galaxy cluster in formation in the primitive universe. The researchers predict that this structure, which is at a distance of 12.5 billion light years from us, will have evolved…

270 Addresses Are Responsible for 55% of All Cryptocurrency Money Laundering
Criminals who keep their funds in cryptocurrency tend to launder funds through a small cluster of online services, blockchain investigations firm Chainalysis said in a report last week. From a report: This includes services like high-risk (low-reputation) crypto-exchange portals, online gambling platforms, cryptocurrency mixing services, and financial services that support cryptocurrency operations headquartered in high-risk jurisdictions. Criminal activity studied in this…
