Galaxies grow their bulges and black holes in diverse ways
Eric F. Bell, Antonela Monachesi, Benjamin Harmsen +5
Galaxies with Milky Way-like stellar masses have a wide range of bulge and black hole masses; in turn, these correlate with other properties such as star formation history. While m…
Diverse Stellar Haloes in Nearby Milky Way-Mass Disc Galaxies
Benjamin Harmsen, Antonela Monachesi, Eric F. Bell +4
We have examined the resolved stellar populations at large galactocentric distances along the minor axis (from 10 kpc up to between 40 and 75 kpc), with limited major axis coverage…
Extragalactic archeology with the GHOSTS Survey I. - Age-resolved disk structure of nearby low-mass galaxies
David Streich, Roelof S. de Jong, Jeremy Bailin +5
We study the individual evolution histories of three nearby low-mass edge-on galaxies (IC 5052, NGC4244, and NGC5023). Using resolved stellar populations, we constructed star count…
The GHOSTS survey. II. The diversity of Halo Color and Metallicity Profiles of Massive Disk Galaxies
Antonela Monachesi, Eric F. Bell, David Radburn-Smith +5
We study the stellar halo color properties of six nearby massive highly inclined disk galaxies using Hubble Space Telescope Advanced Camera for Surveys and Wide Field Camera 3 obse…
On the relation between metallicity and RGB color in HST/ACS data
David Streich, Roelof S. de Jong, Jeremy Bailin +3
The determination of stellar metallicity and its gradient in external galaxies is a difficult task, but crucial for the understanding of galaxy formation and evolution. The color o…
Constraining the age of the NGC 4565 HI Disk Warp: Determining the Origin of Gas Warps
David J. Radburn-Smith, Roelof S. de Jong, David Streich +7
We have mapped the distribution of young and old stars in the gaseous HI warp of NGC 4565. We find a clear correlation of young stars (<600 Myr) with the warp, but no coincident ol…
