Model-dependent metallicities of young stellar populations in TIMER galaxies

Stellar populations in the central regions of disc galaxies provide key constraints on their formation and secular evolution. We investigate the properties of young stellar populations in the centres of nearby barred galaxies from the TIMER survey, using four stellar population models, two based on empirical stellar...

Diagnosing spatial-coherence outer scale, seeing, and dome-induced turbulence from simultaneous multi-wavelength imaging of point-like sources

Atmospheric turbulence causes refractive-index fluctuations that distort the wavefront of light from astronomi cal sources. As starlight propagates through multiple turbulent layers, the cumulative effect sets the achievable image quality (IQ) of observations obtained with ground-based telescopes. Global parameters suc...
