Models of the circumstellar medium of evolving, massive runaway stars moving through the Galactic plane [PDF]
, 2014 At least 5 per cent of the massive stars are moving supersonically through the interstellar medium (ISM) and are expected to produce a stellar wind bow shock.

Extended red objects and stellar-wind bow shocks in the Carina Nebula [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We report the results of infrared photometry on 39 extended red objects (EROs) in the Carina Nebula, observed with the Spitzer Space Telescope. Most EROs are identified by bright, extended 8.0 um emission, which ranges from 10'' to 40'' in size, but our sample also includes 4 EROs identified by extended 24 um emission.

Ram-pressure balance surfaces for an outwardly accelerating stellar wind bow shock [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We study the problem of a stellar wind bowshock (produced by an isotropic wind/plane flowing environment interaction) that lies within the wind acceleration region in the simple, ram-pressure balance approximation. We show that this problem has a simple, approximate analytic solution that produces reasonably accurate results when applied to wind ...

Systematic search for high-energy gamma-ray emission from bow shocks of runaway stars [PDF]
, 2014 Context. It has been suggested that the bow shocks of runaway stars are sources of high-energy gamma rays (E > 100 MeV). Theoretical models predicting high-energy gamma-ray emission from these sources were followed by the first detection of non-thermal ...

Gamma-ray emission from early-type stars interacting with AGN jets
EPJ Web of Conferences, 2013 We study the interaction of early-type stars with the jets of active galactic nuclei. A bow-shock will form as a consequence of the interaction of the jet with the winds of stars and particles can be accelerated up to relativistic energies in these ...

Cometary shaped sources at the Galactic Center - Evidence for a wind from the central 0.2 pc [PDF]
, 2010 In 2007 we reported two cometary shaped sources in the vicinity of Sgr A* (0.8" and 3.4" projected distance), named X7 and X3. The symmetry axes of the two sources are aligned to within 5 degrees in the plane of the sky and the tips of their bow-shocks ...

Massive runaway stars in the Small Magellanic Cloud [PDF]
, 2010 Using archival Spitzer Space Telescope data, we identified for the first time a dozen runaway OB stars in the Small Magellanic Cloud (SMC) through the detection of their bow shocks.

THE MYSTERIOUS SICKLE OBJECT IN THE CARINA NEBULA: A STELLAR WIND INDUCED BOW SHOCK GRAZING A CLUMP? [PDF]
The Astrophysical Journal, 2013 Optical and near-infrared images of the Carina Nebula show a peculiar arc-shaped feature, which we call the "Sickle", next to the B-type star Trumpler 14 MJ 218. We use multi-wavelength observations to explore and constrain the nature and origin of the nebulosity. Using sub-mm data from APEX/LABOCA as well as Herschel far-infrared maps, we discovered a
