CAPOS: The bulge Cluster APOgee Survey II. The intriguing “Sequoia” globular cluster FSR 1758
(EDP Sciences, 2021-08-01)
We present results from a study of 15 red giant members of the intermediate-metallicity globular cluster (GC) FSR 1758 using high-resolution, near-infrared spectra collected with the Apache Point Observatory Galactic ...
MONOS: Multiplicity of Northern O-type Spectroscopic systems: I. Project description and spectral classifications and visual multiplicity of previously known objects
(EDP Sciences, 2019-06-05)
Context. Multiplicity in massive stars is key to understanding the chemical and dynamical evolution of galaxies. Among massive stars, those of O type play a crucial role due to their high masses and short lifetimes. Aims. ...
The cosmic ultraviolet baryon survey (CUBS) - III. Physical properties and elemental abundances of Lyman-limit systems at z < 1
(Oxford, 2021)
We present a systematic investigation of physical conditions and elemental abundances in four optically thick Lyman-limit systems (LLSs) at z = 0.36-0.6 discovered within the cosmic ultraviolet baryon survey (CUBS). Because ...
The Gaia-ESO Public Spectroscopic Survey: Motivation, implementation, GIRAFFE data processing, analysis, and final data products?
(EDP Sciences, 2022-10-01)
Context. The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100 000 stars, including large representative samples of the stellar ...
Weak-lensing mass distributions for 24 X-ray Abell clusters
(UNIV CHICAGO PRESS, 2004-09-20)
We use the weak gravitational lensing effect to study the mass distribution and dynamical state of a sample of 24 X-ray-luminous clusters of galaxies (0.05 < z < 0.31) observed with the FORS1 instrument mounted on the ...
The Structure of a Low-metallicity Giant Molecular Cloud Complex
(2009)
To understand the impact of low metallicities on giant molecular cloud (GMC) structure, we compare far-infrared dust emission, CO emission, and dynamics in the star-forming complex N83 in the Wing of the Small Magellanic ...
SEDIGISM: Structure, excitation, and dynamics of the inner Galactic interstellar medium
(EDP Sciences, 2017-05)
Context. The origin and life-cycle of molecular clouds are still poorly constrained, despite their importance for understanding the evolution of the interstellar medium. Many large-scale surveys of the Galactic plane have ...
Space telescope and optical reverberation mapping project. xii. broad-line Region Modeling of NGC 5548
(IOP Publishing, 2020)
We present geometric and dynamical modeling of the broad line region (BLR) for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The data set includes photometric and spectroscopic monitoring ...
