Massive stars play a key role in environments with very different metallicities. To interpret the role of massive stars in these systems we have to know their...
Massive quiescent galaxies at z 3: A comparison of selection, stellar population, and structural properties with simulation predictions
We study stellar population and structural properties of massive log (M ⋆/M ⊙) > 11 galaxies at z ≈ 2.7 in the Magneticum and IllustrisTNG hydrodynamical...
Massive Relic Galaxies Challenge the Co-evolution of Super-massive Black Holes and Their Host Galaxies
We study a sample of eight massive galaxies that are extreme outliers (3–5σ) in the {M}\bullet ‑ Mbulge local scaling relation. Two of these galaxies are...
We study the preferred environments of z ˜ 0 massive relic galaxies (M⋆ ≳ 1010 M⊙ galaxies with little or no growth from star formation or mergers since z ˜ 2)...
Massive Star Formation and Tidal Structures in HCG 31
We present new broadband optical and near-infrared CCD imaging together with deep optical intermediate-resolution spectroscopy of the Hickson Compact Group 31...
Massive star formation in galaxies with excess ultraviolet emission
From an analysis of almost 2000 Galaxy Evolution Explorer images of galaxies with morphological types ranging from E to Sab, we have found a significant subset...
Massive star formation in the central regions of spiral galaxies
Context: . The morphology of massive star formation in the central regions of galaxies is an important tracer of the dynamical processes that govern the...
Massive star formation in Wolf-Rayet galaxies. I. Optical and NIR photometric results
Aims: We have performed a comprehensive multiwavelength analysis of a sample of 20 starburst galaxies that show the presence of a substantial population of...
Massive star formation in Wolf-Rayet galaxies. II. Optical spectroscopy results
Aims. We have performed a comprehensive multiwavelength analysis of a sample of 20 starburst galaxies that show the presence of a substantial population of very...
