The TYPHOON Stellar Population Synthesis Survey. I. The Young Stellar Population of the Great Barred Spiral NGC 1365

open access: yesThe Astrophysical Journal, 2023
We analyze TYPHOON long-slit-absorption line spectra of the starburst barred spiral galaxy NGC 1365 obtained with the Progressive Integral Step Method covering an area of 15 kpc ^2 .

Distribution and Evolution of Metals in the Magneticum Simulations

open access: yesGalaxies, 2017
Metals are ideal tracers of the baryonic cycle within halos. Their composition is a fossil record connecting the evolution of the various stellar components of galaxies to the interaction with the environment by in- and out-flows.

The Stellar Population of M17

open access: yesThe Astrophysical Journal, 2008
The stellar content of M17 has been investigated by multicolor photometry and spectroscopy. Various independent estimates yield a distance of 2.1 ± 0.2 kpc. The ratio of total-to-selective extinction is R = 3.9. Within a projected area of 3.6 × 3.7 pc, there are several thousand stars.

Investigation of the Stellar Population of Several Polar Ring Galaxies

open access: yesGalaxies, 2016
We present results of our investigation of two multi-spin galaxies which were taken from the catalog of polar ring galaxies. All of them possess nucleus-like knots.

Synthetic stellar populations: single stellar populations, stellar interior models and primordial protogalaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
We present a new set of stellar interior and synthesis models for predicting the integrated emission from stellar populations in star clusters and galaxies of arbitrary age and metallicity. This work differs from existing spectral synthesis codes in a number of important ways, namely (1) the incorporation of new stellar evolutionary tracks, with ...

Streams on FIRE: Populations of Detectable Stellar Streams in the Milky Way and FIRE

open access: yesThe Astrophysical Journal, 2023
We present the first detailed comparison of populations of dwarf galaxy stellar streams in cosmological simulations and the Milky Way. In particular, we compare streams identified around 13 Milky Way analogs in the FIRE-2 simulations to streams observed ...

Multiple Populations in Star Clusters

open access: yesUniverse, 2022
We review the multiple population (MP) phenomenon of globular clusters (GCs): i.e., the evidence that GCs typically host groups of stars with different elemental abundances and/or distinct sequences in photometric diagrams.

Applications of Stellar Population Synthesis in the Distant Universe

open access: yesGalaxies, 2020
Comparison with artificial galaxy models is essential for translating the incomplete and low signal-to-noise data we can obtain on astrophysical stellar populations to physical interpretations which describe their composition, physical properties ...
