Osmium isotope constraints on the proportion of bolide component in Chicxulub impact melt rocks
, 2004 The spatial distribution and amount of material transferred from the bolide involved in the Cretaceous/Tertiary (K/T) event to the target rocks at Chicxulub is still poorly constrained.

Brief communication "Does the Eltanin asteroid tsunami provide an alternative explanation for the Australian megatsunami hypothesis?" [PDF]
Natural Hazards and Earth System Sciences, 2010 The Australian megatsunami hypothesis has been developed over two decades. It charts repeated inundation of the South East Australian coast during the Holocene by bolide impact megatsunamis.

Deciphering the Palaeocene-Eocene thermal maximum by Granger causality test
Geosystems and Geoenvironment, 2023 The Palaeocene-Eocene thermal maximum is a global warming period (∼56 Ma), which is marked by a sharp negative carbon isotope excursion (CIE) that caused by the injection of massive isotopically-light carbon into the ocean-atmosphere.

Physics of the Chelyabinsk bolide [PDF]
Astronomical School’s Report, 2013 Shown, that estimations of the Chelyabinsk body size order of 20–30 m (15/02/2013 phenomenon), publishing in the press, are overstated significantly. Estimations of its explosion height are wrong. On the basis of the destructions by action of the shock wave, the height of explosion must be no more than 10–12 km. We think, that the Chelyabinsk meteorite

, 2022 The composition of Bolides acts somewhat like a series of snapshots or a diary of my life between March 2020 and December 2021, and for me evokes geographical and temporal cues that are very specific for that particular point in time. The source material includes underwater recordings of kelp forests, captured by homemade hydrophones, the ululations of

Geomagnetic effect of the Bering Sea meteoroid
Russian Journal of Earth Sciences, 2020 Possibilities of studies of the geomagnetic effects produced by the interaction of a cosmic bodies with the magnetosphere-ionosphere-atmosphere system are very limited due to extremely small number of examined events.
