Sequence and timing of conditions on early Mars (2011, methodology): “At the Noachian–Hesperian boundary the impact rate may be a factor of 80 greater than rates at present (Neukum et al., 2001; Hartmann and Neukum, 2001).”
Lunar impact basins: Stratigraphy, sequence and ages from superposed impact crater populations measured from Lunar Orbiter Laser Altimeter (LOLA) data (2012, background): “…early surfaces on the Moon that our measurements support weakens the evidence for forms of the Late Heavy Bombardment hypothesis that postulate a lower impact flux before Nectaris, because the cratering record of the Pre-Nectarian must be incomplete [see also Hartmann, 1975; Chapman et al., 2007].”
COMETARY ORIGIN OF THE ZODIACAL CLOUD AND CARBONACEOUS MICROMETEORITES. IMPLICATIONS FOR HOT DEBRIS DISKS (2009, methodology): “This corresponds to a smaller physical cross section and smaller focusing factor of the Moon.”
Water delivery and giant impacts in the 'Grand Tack' scenario (2014, background): “…formation extends from the condensation of the first solids 4.567–4.568 Gyr ago (Amelin et al., 2002; Bouvier and Wadhwa, 2010; Connelly et al., 2012) until the end of heavy bombardment of the inner Solar System around 4.1–3.8 Gyr ago (Tera et al., 1974; Chapman et al., 2007; Bottke et al., 2012).”
A sawtooth-like timeline for the first billion years of lunar bombardment (2012, result): “…ages is consistent with the cataclysm hypothesis, but it has been argued that it could also be the result of biases that work against finding samples with the oldest impact ages (Hartmann, 1975, 2003; see Hartmann et al., 2000 and Chapman et al., 2007 for reviews of the contrasting arguments).”
Mercury’s Weather-Beaten Surface: Understanding Mercury in the Context of Lunar and Asteroidal Space Weathering Studies (2014, background): “However, it can be argued on the basis of Apollo 16 Descartes terrain samples that the age of the Nectaris impact is 3.9 Ga, in which case the same crater counting statistics would indicate a much steeper de- cline in the impact flux between 3.9 and 3.5 Ga (Ryder 1990, 2002; Stöffler and Ryder 2001;”
The Compositional Structure of the Asteroid Belt (2015, background): “Apart from the Os and Ru evidence, and model support that the LHB and the late veneer material were volatile-poor, there is evidence for oceans 4.4-4.3 Byr ago (Cavosie et al., 2005; Mojzsis et al., 2001; Wilde et al., 2001), i.e., 300-400 Myr before the LHB.”
Populating the asteroid belt from two parent source regions due to the migration of giant planets—“The Grand Tack” (2012, background): “…and The Meteoritical Society, 2012.1941 Meteoritics & Planetary Science 47, Nr 12, 1941–1947 (2012) doi: 10.1111/j.1945-5100.2012.01418.x Wadhwa 2010), up to the ‘‘late’’ bombardment of the Moon and inner solar system some 4.1–3.9 Gyr ago (Tera et al. 1974; Chapman et al. 2007; Bottke et al. 2012).”
STATISTICAL STUDY OF THE EARLY SOLAR SYSTEM'S INSTABILITY WITH FOUR, FIVE, AND SIX GIANT PLANETS (2012, background): “The nature of the LHB, however, is still being debated (see Hartmann et al. 2000 and Chapman et al. 2007 for reviews).”
The early martian evolution—Constraints from basin formation ages (2008, background): “For a recent summary, see Chapman et al. (2007).”
The timeline of the lunar bombardment: Revisited (2018, background): “Thus the Moon experienced a heavy bombardment about 600 My after planet formation during which the youngest lunar basins, like Imbrium and Orientale (and possibly also Serenitatis) formed (for reviews see e.g. Hartmann et al., 2000; Chapman et al., 2007; Norman, 2009).”
