Discovering the building blocks of nuclear star clusters
Today’s paper combines new observational data from Gaia with 20 years of multi-wavelength data of the compact dwarf galaxy NGC 5253, reveal a triplet system of star clusters in the centre.
Titan’s icy alley: An elusive surface revealed
Understanding Titan’s surface is no easy task. A 2019 study indicates an unusual ice-rich feature on this moon of Saturn.
Meet the AAS Keynote Speakers: Dr. Brian Metzger
We’ve seen supernovae, but what’s a kilonova? Professor Brian Metzger will tell us all about these high energy events in his talk at #AAS235.
How do bound star clusters form?
Today’s paper tests five different models of star cluster formation to find out how gravitationally-bound star clusters form in our Universe.
Elusive black holes: Have we found the ‘middle sibling’?
Today’s paper presents an intermediate mass black hole (IMBH) hiding within a dense star cluster. X-ray and optical observations over 15 years allow the authors to explore the different stages of this IMBH feasting on an unlucky star.
Dwarf Galaxies without Dark Matter
Today’s paper looks at observations of 19 low mass galaxies which appear to contain no dark matter, potentially challenging our overall understanding of galaxy formation.
