Terrestrial Effects of Nearby Supernovae: Updated Modeling
Brian C. Thomas, Alexander M. Yelland
We have reevaluated recent studies of the effects on Earth by cosmic rays (CRs) from nearby supernovae (SNe) at 100 and 50 pc, in the diffusive transport CR case, here including an…
Gamma Ray Bursts: Not so Much Deadlier than We Thought
Brian C. Thomas, Dimitra Atri, Adrian L. Melott
We analyze the additional effect on planetary atmospheres of recently detected gamma-ray burst afterglow photons in the range up to 1 TeV. For an Earth-like atmosphere we find that…
From Cosmic Explosions to Terrestrial Fires?: A Reply
Adrian L. Melott, Brian C. Thomas
Deschamps and Mottez (hereafter DM) argue that the Gauss-Matuyama terrestrial magnetic field reversal may have left a vanishing main dipole moment to the field for a time of order…
Ozone depletion-induced climate change following a 50 pc supernova
Brian C. Thomas, Cody L. Ratterman
Ozone in Earth's atmosphere is known to have a radiative forcing effect on climate. Motivated by geochemical evidence for one or more nearby supernovae about 2.6 million years ago,…
From cosmic explosions to terrestrial fires?
Adrian L. Melott, Brian C. Thomas
Multiple lines of evidence point to one or more moderately nearby supernovae, with the strongest signal ~2.6 Ma. We build on previous work to argue for the likelihood of cosmic ray…
Climate change via co2 drawdown from astrophysically initiated atmospheric ionization?
Adrian Melott, Brian C. Thomas, Brian D. Fields
Motivated by the occurrence of a moderately nearby supernova near the beginning of the Pleistocene, possibly as part of a long-term series beginning in the Miocene, we investigate…
