The optical, seismic, and infrasound signature of the March 5 2022, bolide over Central Italy [PDF]
Scientific Reports, 2023 On March 5, 2022, a 12 kg meteoroid crossed the sky above Central Italy and was observed by three different observational systems: the PRISMA all-sky camera network (10 stations), the Italian national seismic network (61 stations), and a 4-element ...

An Algorithmic Approach for Detecting Bolides With the Geostationary Lightning Mapper [PDF]
Sensors, 2019 The Geostationary Lightning Mapper (GLM) instrument onboard the GOES 16 and 17 satellites can be used to detect bolides in the atmosphere. This capacity is unique because GLM provides semi-global, continuous coverage and releases its measurements ...

No Consistent Shift in Leaf Dry Mass per Area Across the Cretaceous—Paleogene Boundary [PDF]
Frontiers in Plant Science, 2022 The Chicxulub bolide impact has been linked to a mass extinction of plants at the Cretaceous—Paleogene boundary (KPB; ∼66 Ma), but how this extinction affected plant ecological strategies remains understudied.

Did avian-like pulmonary anatomy increase the susceptibility of dinosaurs to fungal diseases? Extending the “fungal infection mammalian selection” hypothesis [PDF]
mBioThe Cretaceous-Paleogene (K-Pg) bolide impact caused the extinction of over half of all plant and animal species. The “fungal infection mammalian-selection” (FIMS) hypothesis, first proposed in 2005, suggested that a post-K-Pg fungal bloom created ...

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous-Paleogene boundary in western North America. [PDF]
Am J BotAbstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Signatures of gravity wave-induced instabilities in balloon lidar soundings of polar mesospheric clouds [PDF]
Atmospheric Chemistry and Physics, 2023 The Balloon Lidar Experiment (BOLIDE), which was part of the Polar Mesospheric Cloud Turbulence (PMC Turbo) Balloon Mission has captured vertical profiles of PMCs during a 6 d flight along the Arctic circle in July 2018. The high-resolution soundings (20
