The Large- and Small-Scale Structures of Dust in the Star-forming Perseus Molecular Cloud (2006, methodology): “Adopting a common dust temperature of 15 K, we find the submillimetre clumps in Perseus are well fit by a broken power law with α ∼ 2, which falls within the range of slopes found by previous authors, varying from α ∼ 1 - 1.5 (Johnstone et al. 2000b) to α ∼ 2 (Reid & Wilson 2005).”

(2012).”

An Extinction Threshold for Protostellar Cores in Ophiuchus (2004, unknown): “All but 2 of these objects are associated with previously identified substructure in the smaller map of Johnstone et al. (2000a) surrounding the known Oph cores (i.e., A–”
The “Mysterious” Origin of Brown Dwarfs (2002, background): “…of prestellar condensations is indistinguishable from the stellar IMF (Motte et al. 1998, 2001; Testi & Sargent 1998; Onishi et al. 1999; Johnstone et al. 2000b, 2000a, 2001; Onishi et al. 2002), both in the functional shape and in the range of masses, including BD mass cores (Walsh et…”

Cluster Formation in Protostellar Outflow-driven Turbulence (2005, result): “…observations of the nearby cluster-forming region, ther Oph cloud core, which uncovered prestellar condensations with a mass spectrum that resembles the Salpeter IMF (Motte et al. 1998; Johnstone et al. 2000; Stanke et al. 2006; see Testi & Sargent 1998 for a similar result for the Serpens core).”
ANALYTICAL STAR FORMATION RATE FROM GRAVOTURBULENT FRAGMENTATION (2011, background): “A similar density-threshold for significant dense core population has been identified in several surveys (Onishi et al. 1998, Johnstone et al. 2000, Kirk et al. 2006, Enoch et al. 2007, Lada et al. 2010, André et al. 2010).”
Analytical Theory for the Initial Mass Function: CO Clumps and Prestellar Cores (2008, background): “…dense core mass function (CMF) have shown its striking similarity with the stellar IMF, the former one being shifted by a factor of ’2Y4 toward higher masses with respect to the latter one (Motte et al. 1998; Testi & Sargent 1998; Johnstone et al. 2000; André et al. 2007; Alfves et al. 2007).”
Fragmentation and mass segregation in the massive dense cores of Cygnus X (2009, background): “Motte et al. (1998), followed by a large number of other works (e.g. Testi & Sargent 1998; Johnstone et al. 2000; Nutter & Ward-Thompson 2007), could trace that the mass distribution of pre-stellar cores and Class 0 YSOs have the same shape than the IMF.”

(2000), for the cores in Serpens by Testi & Sargent (1998), and for the cores in the Orion B molecular cloud by Mott”
