The Astrophysical Journal, 2023 We study how environment regulates the star formation cycle of 33 Virgo Cluster satellite galaxies on 720 pc scales. We present the resolved star-forming main sequence for cluster galaxies, dividing the sample based on their global H i properties and ...

Star cluster formation in cosmological simulations – III. Dynamical and chemical evolution [PDF]
Monthly notices of the Royal Astronomical Society, 2018 In previous papers of this series, we developed a new algorithm for modeling the formation of star clusters in galaxy formation simulations. Here we investigate how dissolution of bound star clusters affects the shape of the cluster mass function and the

A Study of Be Stars in Clusters [PDF]
Symposium - International Astronomical Union, 1976 Calibrated spectrograms at Hα of 566 stars in 29 young galactic clusters led to the detection of 41 Be stars in clusters. Using cluster membership we have inferred ages and intrinsic (B – V) colors of Be stars to permit a discussion of their evolutionary states.Rotating stars can become Be stars in their early hydrogen burning evolution away from the ...

The E-MOSAICS project: simulating the formation and co-evolution of galaxies and their star cluster populations [PDF]
, 2017 We introduce the MOdelling Star cluster population Assembly In Cosmological Simulations within EAGLE (E-MOSAICS) project. E-MOSAICS incorporates models describing the formation, evolution, and disruption of star clusters into the EAGLE galaxy formation ...

Sub-clinical abnormalities detected by PET/MRI in household tuberculosis contacts
BMC Infectious Diseases, 2019 Background The understanding of early events following TB exposure is limited by traditional tests that rely on detection of an immune response to infection, which is delayed, or on imaging tests with low sensitivity for early disease.

The R136 star cluster dissected with Hubble Space Telescope/STIS. I. Far-ultraviolet spectroscopic census and the origin of He II λ1640 in young star clusters [PDF]
, 2016 We introduce a Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) stellar census of R136a, the central ionizing star cluster of 30 Doradus.

Molecular Gas Properties in Young Stellar Clusters with a Suppressed Star Cluster Wind
The Astrophysical Journal Letters, 2023 In compact and dense star-forming clouds a global star cluster wind could be suppressed. In this case stellar feedback is unable to expel the leftover gas from the cluster. Young massive stars remain embedded in a dense residual gas and stir it by moving

The Star Formation History of the Milky Way’s Nuclear Star Cluster
The Astrophysical Journal, 2023 We report the first star formation history study of the Milky Ways nuclear star cluster (NSC), which includes observational constraints from a large sample of stellar metallicity measurements.
