We construct revised near-infrared absolute magnitude calibrations for 126 Galactic Wolf-Rayet (WR) stars at known distances, based in part upon recent large scale spectroscopic surveys. Application to 246 WR stars located in the field, permits us to map their galactic distribution. As anticipated, WR stars generally lie in the thin disk (~40pc half width at half maximum) between galactocentric radii 3.5-10kpc, in accordance with other star formation tracers. We highlight 12 WR stars located at… 

Wolf–Rayet stars in the Antennae unveiled by MUSE

We present the analysis of archival Very Large Telescope (VLT) Multi-Unit Spectroscopic Explorer (MUSE) observations of the interacting galaxies NGC 4038/39 (a.k.a. the Antennae) at a distance of

Unlocking Galactic Wolf–Rayet stars with Gaia DR2 – II. Cluster and association membership

Galactic Wolf-Rayet (WR) star membership of star forming regions can be used to constrain the formation environments of massive stars. Here, we utilise $\textit{Gaia}$ DR2 parallaxes and proper

A spectroscopic multiplicity survey of Galactic Wolf-Rayet stars

Context. It is now well established that the majority of massive stars reside in multiple systems. However, the effect of multiplicity is not sufficiently understood, resulting in a plethora of

On the Apparent Absence of Wolf–Rayet+Neutron Star Systems: The Curious Case of WR124

Among the different types of massive stars in advanced evolutionary stages is the enigmatic WN8h type. There are only a few Wolf–Rayet (WR) stars with this spectral type in our Galaxy. It has long

Unlocking Galactic Wolf–Rayet stars with Gaia DR2 – I. Distances and absolute magnitudes

We obtain distances to 383 Galactic Wolf–Rayet (WR) stars from Gaia DR2 parallaxes and Bayesian methods, with a prior based on H ii regions and dust extinction. Distances agree with those from

The Galactic WC and WO stars

Wolf-Rayet stars of the carbon sequence (WC stars) are an important cornerstone in the late evolution of massive stars before their core collapse. As core-helium burning, hydrogen-free objects with

Identifying two groups of massive stars aligned in the l ~ 38° Galactic direction

Context. Recent near-infrared data have contributed to unveiling massive and obscured stellar populations in both new and previously known clusters in our Galaxy. These discoveries have lead us to

A deep near-infrared spectroscopic survey of the Scutum-Crux arm for Wolf-Rayet stars

We present an NTT/SOFI spectroscopic survey of infrared selected Wolf-Rayet candidates in the Scutum-Crux spiral arm (298 < l < 340, |b| < 0.5). We obtained near-IR spectra of 127 candidates,
