Career

Between 2011 and 2016 Rafelski held postdoc positions at IPAC, Caltech, and NASA Goddard, moving on to a staff position at the Space Telescope Science Institute in Baltimore in 2016. [5] Starting in 2020, he is the branch manager for the Cosmic Origins Spectrograph (COS), a science instrument that was installed on the Hubble Space Telescope during Servicing Mission 4 (STS-125) in May 2009. [6]

Rafelski studies the formation and evolution of galaxies by looking at the physical characteristics and processes of high redshift galaxies and their associated gas reservoirs, inflows, and outflows. He started publishing already as an undergraduate student, both in astronomy [7] and heavy-ion physics. [8] Since then he has co-authored more than 200 scientific papers. [9]

Personal life

Marc Rafelski is son of Johann and Helga Rafelski, and adoptive son of Victoria Grossack. He  is married to Lauren Anne Elmegreen Rafelski. The couple has two children and lives in Maryland. [10]

A globular cluster is a spheroidal conglomeration of stars. Globular clusters are bound together by gravity, with a higher concentration of stars towards their centers. They can contain anywhere from tens of thousands to many millions of member stars. Their name is derived from Latin globulus. Globular clusters are occasionally known simply as "globulars".

The Galactic Center is the rotational center, the barycenter, of the Milky Way galaxy. Its central massive object is a supermassive black hole of about 4 million solar masses, which is called Sagittarius A*, a compact radio source which is almost exactly at the galactic rotational center. The Galactic Center is approximately 8 kiloparsecs (26,000 ly) away from Earth in the direction of the constellations Sagittarius, Ophiuchus, and Scorpius, where the Milky Way appears brightest, visually close to the Butterfly Cluster (M6) or the star Shaula, south to the Pipe Nebula.
