Context. Massive stars form in groups and their winds and supernova explosions create superbubbles up to kpc in size. The fate of their ejecta is of vital importance for the dynamics of the interstellar medium, for chemical evolution models, and the chemical enrichment of galactic halos and the intergalactic medium. However, ejecta kinematics and the characteristic scales in space and time have not been explored in great detail beyond 10 ka. Aims. Through measurement of radioactive 26 Al with… Expand
Galactic 26Al traces metal loss through hot chimneys
Radioactive 26Al is an excellent tracer for metal ejection in the Milky Way, and can provide a direct constraint on the modelling of supernova feedback in galaxy evolution. Gamma-ray observations ofExpand
Feedback by massive stars and the emergence of superbubbles II. X-ray properties
Context. In a previous paper we investigated the energy transfer of massive stars to the interstellar medium (ISM) as a function of time and the geometrical configuration of three massive stars viaExpand
Surround and Squash: the impact of superbubbles on the interstellar medium in Scorpius–Centaurus OB2
Context. Feedback by massive stars shapes the interstellar medium and is thought to influence subsequent star formation. The details of this process are under debate. Aims. We exploited observationalExpand
26Al kinematics: superbubbles following the spiral arms? Constraints from the statistics of star clusters and HI supershells
Context. High-energy resolution spectroscopy of the 1.8 MeV radioactive decay line of 26Al with the SPI instrument onboard the INTEGRAL satellite has recently revealed that diffuse 26Al has higherExpand
Synthetic 26Al emission from galactic-scale superbubble simulations
Emission from the radioactive trace element 26Al has been observed throughout the Milky Way with the COMPTEL and INTEGRAL satellites. In particular, the Doppler shifts measured with INTEGRALExpand
Positron Annihilation in the Milky Way: Searching for the source of Galactic antimatter
For more than 50 years, the rate and distribution of positron (anti-electron) annihilation in the Milky Way has puzzled astronomers. Positrons with low („ MeV) initial energies are likely to beExpand
Nucleosynthesis in Supernovae
We present the status and open problems of nucleosynthesis in supernova explosions of both types, responsible for the production of the intermediate mass, Fe-group and heavier elements (with theExpand
Constraints on positron annihilation kinematics in the inner Galaxy
Context. The annihilation of cosmic positrons with electrons in the interstellar medium results in the strongest persistent γ-ray line signal in the sky. For the past 50 yr, this 511 keV emission –Expand
Concurrent formation of supermassive stars and globular clusters: implications for early self-enrichment
We present a model for the concurrent formation of globular clusters (GCs) and supermassive stars (SMSs, ≳103 M⊙) to address the origin of the HeCNONaMgAl abundance anomalies in GCs. GCs form inExpand
Comparing simulated 26Al maps to gamma-ray measurements
Context. The diffuse gamma-ray emission of $^{26}{\rm Al}$ at 1.8 MeV reflects ongoing nucleosynthesis in the Milky Way, and traces massive-star feedback in the interstellar medium due to its 1 MyrExpand


Metal enrichment of the intracluster medium: SN‐driven galactic winds
We investigate the role of supernova (SN)-driven galactic winds in the chemical enrichment of the intracluster medium (ICM). Such outflows on galactic scales have their origin in huge star formingExpand
Feedback by massive stars and the emergence of superbubbles - I. Energy efficiency and Vishniac instabilities
Context. Massive stars influence their environment via stellar winds , ionising radiation and supernova explosions. This is sign ified by observed interstellar bubbles. Such “feedback” is anExpand
Radioactive 26Al from the Scorpius-Centaurus Association
Context. The Scorpius-Centaurus association is the most-nearby group of massive and young stars. As nuclear-fusion products are ejected by massive stars and supernovae into the surroundingExpand
A huge reservoir of ionized gas around the Milky Way: Accounting for the Missing Mass?
Most of the baryons from galaxies have been "missing" and several studies have attempted to map the circumgalactic medium (CGM) of galaxies in their quest. We report on X-ray observations made withExpand
Evidence of a bisymmetric spiral in the Milky Way
It is extremely difficult to observe the spiral structure of the Milky Way because of our viewing point within the Galactic disc. The aims of this paper are to clarify the structure of the Galaxy byExpand
Gas dynamics and large-scale morphology of the Milky Way galaxy
We present a new model for the gas dynamics in the galactic disc inside the orbit of the Sun. Quasi-equilibrium flow solutions are determined in the gravitational potential of the deprojected COBEExpand
Radioactive 26Al from massive stars in the Galaxy
High spectral resolution measurements of 26Al emission at 1808.65 keV demonstrate that the 26Al source regions corotate with the Galaxy, supporting its Galaxy-wide origin and determining a present-day equilibrium mass of 2.8 (± 0.8) solar masses of 27Al. Expand
