Stellar populations across the ngc 4244 truncated galactic disk
Roelof S. de Jong,Anil C. Seth,D. J. Radburn-Smith,Eric F. Bell,Thomas M. Brown,James S. Bullock,Stéphane Courteau,Julianne J. Dalcanton,Henry C. Ferguson,Paul Goudfrooij,S. Holfeltz,Benne W. Holwerda,Chris W. Purcell,Jonathan Sick,Daniel B. Zucker +14 more
TL;DR: In this paper, the authors used HST/ACS to study the resolved stellar populations of the nearby, nearly edge-on galaxy NGC 4244 across its outer disk surface density break and found that the break occurs at the same radius for young, intermediate age, and old stars.
