A planet having protective ozone within the collimated beam of a Gamma Ray Burst (GRB) may suffer ozone depletion, potentially causing a mass extinction event to existing life on a planet's surface and oceans. We model the dangers of long GRBs to planets in the Milky Way and utilize a static statistical model of the Galaxy that matches major observable properties, such as the inside-out star formation history, metallicity evolution, and 3-dimensional stellar number density distribution. The GRB… Expand

Exploring the cosmic evolution of habitability with galaxy merger trees
We combine inferred galaxy properties from a semi-analytic galaxy evolution model incorporating dark matter halo merger trees with new estimates of supernova and gamma ray burst rates as a functionExpand
Galactic Effects on Habitability
The galactic environment has been suspected to influence planetary habitability in many ways. Very metal-poor regions of the Galaxy, or those largely devoid of atoms more massive than H and He, areExpand

Elliptical galaxies have dynamically hot (σ 1D ∼100–300 km s−1) populations of stars, and presumably, smaller objects like comets. Because interstellar minor bodies are moving much faster, they hitExpand
The Habitability of the Galactic Bulge
Analytical models of the star density in the bulge are used to provide estimates of the rate of catastrophic events and of the diffusion timescales for life over interstellar distances. Expand
Solar system exposure to supernova γ radiation
Abstract Planetary habitability may be affected by exposure to γ radiation from supernovae (SNe). Records of Earth history during the late Quaternary Period (40 000 years to present) allow testingExpand
The Habitability of Our Evolving Galaxy
The notion of a galactic habitable zone (GHZ), or regions of the Milky Way galaxy that preferentially maintain the conditions to sustain complex life, has recently gained attention due to theExpand
Advanced aspects of Galactic habitability
The aim is to numerically investigate the dynamics of opposed processes of expansion and extinction of life in the Galaxy using a new type of numerical simulation based on 1D probabilistic cellular automaton with very high temporal resolution. Expand
Multiverse Predictions for Habitability: Fraction of Life That Develops Intelligence
Do mass extinctions affect the development of intelligence? If so, we may expect to be in a universe that is exceptionally placid. We consider the effects of impacts, supervolcanoes, globalExpand
The Drake Equation as a Function of Spectral Type and Time
This chapter draws upon astronomical observations and modeling to constrain the prevalence of communicative civilizations in the galaxy. We discuss the dependence of the Drake equation parameters onExpand
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


While there are numerous indications that gamma-ray bursts (GRBs) arise from the deaths of massive stars, the GRB rate does not follow the global cosmic star formation rate and, within their hosts,Expand
Cosmological Gamma-Ray Bursts and Evolution of Galaxies
Evolution of the rate density of cosmological gamma-ray bursts (GRBs) is calculated and compared to the BATSE brightness distribution in the context of binary neutron star mergers as the source ofExpand
Gamma-ray bursts and the history of star formation
Popular models for the origin of gamma-ray bursts (GRBs) include short-lived massive stars as the progenitors of the fireballs. Hence the redshift distribution of GRBs should track the cosmic starExpand
Terrestrial implications of cosmological gamma-ray burst models
The observation by the BATSE instrument on the Compton Gamma Ray Observatory that gamma-ray bursts (GRBs) are distributed isotropically around the Earth but nonuniformly in distance has led to theExpand

Can life survive Gamma-Ray Bursts in the high-redshift universe?
Nearby Gamma-Ray Bursts (GRBs) have been proposed as a possible cause of mass extinctions on Earth. Due to the higher event rate of GRBs at higher redshifts, it has been speculated that life as weExpand

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
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
Possible role of gamma ray bursts on life extinction in the universe.
It is found that the probability of a lethal GRB is much larger in the inner Milky Way (95% within a radius of 4 kpc from the galactic center), making it inhospitable to life, and the safest environments for life are the lowest density regions in the outskirts of large galaxies, and life can exist in only ≈10% of galaxies.
