Dave Strickland is an astrophysicist credited as first author of a study of X-rays from the M82 galactic wind, with Trevor Ponman and Ian Stevens. Their analysis detected wind emission several kiloparsecs from the galaxy and compared its spectrum at different heights.

The spatial variation showed why an integrated brightness alone is insufficient: different regions constrain the gas temperature, distribution and plausible heating mechanisms. The paper's archive byline uses Dave Strickland and lists the University of Birmingham affiliation.^[ref]

Trevor Ponman is an astrophysicist who studies hot gas in galaxies, galaxy groups and galaxy clusters. Such gas records both gravitational confinement and the energy supplied by stellar activity.^[ref]

With Dave Strickland and Ian Stevens, he analysed diffuse X-ray emission from the M82 galactic wind. Separating point sources from extended emission allowed the team to infer properties of the outflowing gas and test physical explanations for its radiation.^[ref]
