The segmented spiral structure of the Solar neighbourhood traced by young clustered populations
M. Carmen Sánchez-Gil, Emilio J. Alfaro
The Milky Way spiral pattern remains poorly constrained, and the youngest tracers in the solar neighbourhood do not always follow a few smooth, continuous logarithmic arms. We anal…
Hierarchical Bayesian approach for estimating physical properties in nearby galaxies: Age Maps (Paper II)
M. Carmen Sánchez-Gil, Emilio J. Alfaro, Miguel Cerviño +3
One of the fundamental goals of modern astrophysics is to estimate the physical parameters of galaxies. We present a hierarchical Bayesian model to compute age maps from images in…
Age patterns in a sample of nearby spiral galaxies
M. Carmen Sánchez-Gil, D. Heath Jones, Enrique Pérez +3
We present the burst ages for young stellar populations in a sample of six nearby (< 10 Mpc) spiral galaxies using a differential pixel-based analysis of the ionized gas emission.…
