Abstract Gamma-ray bursts (GRBs) are a class of highly energetic explosions emitting radiation in a very short timescale of a few seconds and with a very narrow opening angle. Although, all GRBs observed so far are extragalactic in origin, there is a high probability of a GRB of galactic origin beaming towards the Earth in the past ∼0.5 Gyr. We define the level of catastrophic damage to the biosphere as approximation 100 kJ m−2, based on Thomas et al. (2005a, b). Using results in Melott… Expand
Ground-Level Ozone Following Astrophysical Ionizing Radiation Events: An Additional Biological Hazard?
The amount of ozone produced in the lower atmosphere for the case of a gamma-ray burst is examined and it is found that the values are too small to pose a significant additional threat to the biosphere. Expand
Gamma-ray bursts: not so much deadlier than we thought
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 there is a smallExpand
Solar irradiance changes and photobiological effects at earth's surface following astrophysical ionizing radiation events.
The Tropospheric Ultraviolet and Visible radiative transfer model is employed to expand and improve calculations of surface-level irradiance and biological impacts following an ionizing radiation event and it is found that past work overestimated UVB irradiance but that relative estimates for increase in exposure to DNA-damaging radiation are still similar to the improved calculations.

Solar Irradiance Changes and Phytoplankton Productivity in Earth's Ocean Following Astrophysical Ionizing Radiation Events.
Here, the results of previous simulations of incident spectral irradiance following an ionizing radiation event are used to predict changes in terran productivity focusing on photosynthesis of marine phytoplankton, based on a spectral model of photosynthetic response. Expand
Long-term prospects: Mitigation of supernova and gamma-ray burst threat to intelligent beings
Abstract We consider global catastrophic risks due to cosmic explosions (supernovae, magnetars and gamma-ray bursts) and possible mitigation strategies by humans and other hypothetical intelligentExpand
Three explanations for extraterrestrials: sensible, unlikely, mad
Abstract The Fermi Paradox (or Question) has moved back into central focus. This is for a number of reasons, not least the evidence for both the abundance and antiquity of many extra-solar systems,Expand
Characterizing Exoplanet Habitability
Habitability is a measure of an environment's potential to support life, and a habitable exoplanet supports liquid water on its surface. However, a planet's success in maintaining liquid water on itsExpand

The Far Future Argument for Confronting Catastrophic Threats to Humanity: Practical Significance and Alternatives
Sufficiently large catastrophes can affect human civilization into the far future: thousands, millions, or billions of years from now, or even longer. The far future argument says that people shouldExpand


Terrestrial Ozone Depletion Due to a Milky Way Gamma-Ray Burst
The first detailed computation of the effects of a gamma-ray burst in the Earth's atmosphere of one such impulsive event is performed, lending support to the hypothesis that a GRB may have initiated the late Ordovician mass extinction. Expand
Gamma-Ray Bursts and the Earth: Exploration of Atmospheric, Biological, Climatic, and Biogeochemical Effects
Gamma-ray bursts (GRBs) are likely to have made a number of significant impacts on the Earth during the last billion years. The gamma radiation from a burst within a few kiloparsecs would quicklyExpand
Terrestrial Consequences of Spectral and Temporal Variability in Ionizing Photon Events
The effect of many astrophysical events causing atmospheric ionization can be approximated without including time development by generalizing atmospheric computations to include a broad range of peak photon energies and investigating the effect of burst duration. Expand
Did a gamma-ray burst initiate the late Ordovician mass extinction?
A GRB could trigger the global cooling which occurs at the end of the Ordovician period that follows an interval of relatively warm climate, and some of the patterns of extinction and survivorship at this time may be attributable to elevated levels of UV radiation reaching the Earth. Expand
Biological implications of high-energy cosmic ray induced muon flux in the extragalactic shock model
The biological dose resulting from enhanced muon exposure from cosmic rays and their implications for terrestrial biodiversity variations are computed using the Monte Carlo simulation package CORSIKA. Expand
Astrophysical ionizing radiation and Earth: a brief review and census of intermittent intense sources.
This review estimates the intensities and rates of occurrence of many kinds of strong radiation bursts by astrophysical entities, ranging from gamma-ray bursts at cosmological distances to the Sun itself, and notes for the first time that so-called "short-hard" gamma-rays bursts are a substantial threat, comparable in magnitude to supernovae and greater than that of the higher-luminosity long bursts considered in most past work.

Modeling high-energy cosmic ray induced terrestrial muon flux: A lookup table
Abstract On geological timescales, the Earth is likely to be exposed to an increased flux of high-energy cosmic rays (HECRs) from astrophysical sources such as nearby supernovae, gamma-ray bursts orExpand
Calculations presented in this paper suggest that supernovae and gamma ray bursts are likely to produce sea-level radiation exposures of about 1 Gy with a mean interval of about five million years and sea- level radiation exposed of about 0.2 Gy every million years. Expand
Astrophysical and Astrobiological Implications of Gamma-Ray Burst Properties
Combining results from Schmidt for the local cosmic rate and mean peak luminosity of γ-ray bursts (GRBs) with results on the history of the cosmic star formation rate (SFR), we provide estimates forExpand
