A new catalog of homogenised absorption line indices for Milky Way globular clusters from high-resolution integrated spectroscopy. Astrophysical Journal Supplement, 227(2), Article 24. https://doi.org/10.3847/1538-4365/227/2/24

We perform integrated spectroscopy of 24 Galactic globular clusters (GGCs). Spectra are observed from one core radius for each cluster with a high wavelength resolution of ~2.0 Å FWHM. In combination with two existing data sets from Puzia et al. and...

New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion temperature rise scales with the square of the reconnecting field. Dur...

We analyze the angular momenta of massive star-forming galaxies (SFGs) at the peak of the cosmic star formation epoch (z ~ 0.8–2.6). Our sample of ~360 log(M */M ⊙) ~ 9.3–11.8 SFGs is mainly based on the KMOS3D and SINS/zC-SINF surveys of Hα kinemati...

We present the stellar mass (M*), and K-corrected K-band absolute magnitude (MK) Tully–Fisher relations (TFRs) for subsamples of the 584 galaxies spatially resolved in H α emission by the KMOS Redshift One Spectroscopic Survey (KROSS). We model the v... Read More about The KMOS Redshift One Spectroscopic Survey (KROSS): the Tully–Fisher relation at z ∼ 1.
