We present the results of a high angular resolution (4″), multi-transition analysis of the molecular gas in M 82. The analysis is based on the two lowest transitions of 12CO and the ground transition of the rare isotopomeres 13CO and C18O measured with the PdBI, the BIMA array and the IRAM 30m telescope.

THE DISRUPTION OF GIANT MOLECULAR CLOUDS BY RADIATION PRESSURE & THE EFFICIENCY OF STAR FORMATION IN GALAXIES (2009, methodology): “The galaxy is small compared to the Milky Way, with a circular velocityvc ≈ 110km s−1 (Young & Scoville 1984), and a CO inferred gas mass 2× 108M⊙ inside r = 350pc (Weiß et al. 2001) (adjusted to our assumed distance), yielding a gas surface density Σg ≈ 0.1gcm−2 and a gas fractionfg ≈ 0.2.”
Tracing the molecular gas in distant submillimetre galaxies via CO(1-0) imaging with the EVLA (2010, background): “…with high-resolution imaging that resolves the gas discs in ULIRGs (Downes & Solomon 1998), while 13CO and multi-J 12CO line measurements (e.g. Mao et al. 2000; Weiß et al. 2001) that allow the mean optical depth of the 12CO J = 1–0 line to be determined can also achieve this – see Section4.”
THE INTERSTELLAR MEDIUM IN DISTANT STAR-FORMING GALAXIES: TURBULENT PRESSURE, FRAGMENTATION, AND CLOUD SCALING RELATIONS IN A DENSE GAS DISK AT z = 2.3 (2011, background): “…emission compared to highJ lines has recently been reported for a number of high-redshift sub-millimetre galaxies (Ivison et al. 2011; Riechers et al. 2011a,b) in addition to low redshift starbursts (e.g. Papadopoulos & Seaquist 1998; Mao et al. 2000; Weiß et al. 2001, 2005; Walter et al. 2002).”

Molecular Gas in M82: Resolving the Outflow and Streamers (2002, methodology): “Interferometric CO studies of M 82's molecular component have so far been limited to the central kpc (Shen & Lo 1993, Neininger et al. 1998, Weiß et al. 1999, Weiß et al. 2001).”
Massive molecular outflows and evidence for AGN feedback from CO observations (2013, methodology): “A similar result has been found in M 82, where a detailed modelling of the conversion factor of the gas in the outflow has been performed by Weiß et al. (2001) and Walter et al. (2002).”
The Resolved Properties of Extragalactic Giant Molecular Clouds (2008, background): “This can be understood in terms of a larger emissivity per CO molecule in starburst galaxies, stemming from a higher excitation state due to larger physical temperatures and volume densities in these environments (e.g., 14 Weiß et al. 2001).”
