We continue former work on the modeling of potential effects of Gamma Ray Bursts on Phanerozoic Earth. We focus on global biospheric effects of ozone depletion and model the spectral reduction of light by NO2 formed in the stratosphere. We also illustrate the current complexities involved in the prediction of how terrestrial ecosystems would respond to this kind of burst. We conclude that more biological field and laboratory data are needed to reach even moderate accuracy in this modeling.

The past, present and future supernova threat to Earth’s biosphere
A brief review of the threat posed to Earth’s biosphere via near-by supernova detonations is presented. The expected radiation dosage, cosmic ray flux and expanding blast wave collision effects areExpand
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
Solar irradiance changes and photobiological effects at earth's surface following astrophysical ionizing radiation events.
TLDR
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.

Radiation as a Constraint for Life in the Universe
In this chapter, we present an overview of sources of biologically relevant astrophysical radiation and effects of that radiation on organisms and their habitats. We consider both electromagnetic andExpand
Evaluating galactic habitability using high-resolution cosmological simulations of galaxy formation
Abstract We present the first model that couples high-resolution simulations of the formation of local group galaxies with calculations of the galactic habitable zone (GHZ), a region of space whichExpand

TLDR
It is shown that if there is a periodic extinction signal at all, it is much more likely to result from a combination of a comparatively weak periodic cause and various random factors. Expand

Abstract The Zoo solution to Fermi's Paradox proposes that extraterrestrial intelligences (ETIs) have agreed to not contact the Earth. The strength of this solution depends on the ability for ETIs toExpand

An Aquatic Habitability Index is proposed, based on Quantitative Habitability Theory, and considering a very general model for life. It is a primary habitability index, measuring habitability forExpand

The brief reviews and essays that make up this final chapter are intended to provide some detailed information and reference material on recent research topics in astronomy and astrophysics. It isExpand
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

Short-term effects of gamma ray bursts on Earth
The aim of the present work is to study the potential short-term atmospheric and biospheric influence of Gamma Ray Bursts on the Earth. We focus in the ultraviolet flash at planet’s surface, whichExpand
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

In this paper we present a unified, quantitative synthesis of analytical and numerical calculations of the effects that could be caused on Earth by a gamma-ray burst (GRB), considering atmosphericExpand
Evidence for nearby supernova explosions.
TLDR
It is proposed that approximately 2 Myr ago, one of the SNe exploded close enough to Earth to seriously damage the ozone layer, provoking or contributing to the Pliocene-Pleistocene boundary marine extinction. Expand
The Galactic Habitable Zone: Galactic Chemical Evolution
Abstract We propose the concept of a “Galactic Habitable Zone” (GHZ). Analogous to the Circumstellar Habitable Zone (CHZ), the GHZ is that region in the Milky Way where an Earth-like planet canExpand
Galactic Chemical Evolution
The subject of Galactic chemical evolution is now in a very confused state, because of the freedom exercised by theoreticians in choice of assumptions and because of ambiguities in observationalExpand

TLDR
Several studies suggest that the influence of UV-B at the ecosystem level may be more pronounced on community and trophic level structure, and hence on subsequent biogeochemical cycles, than on biomass levels per se. Expand
