As a copious source of gamma rays, a nearby galactic gamma ray burst (GRB) can be a threat to life. Using recent determinations of the rate of GRBs, their luminosity function, and properties of their host galaxies, we estimate the probability that a life-threatening (lethal) GRB would take place. Amongst the different kinds of GRBs, long ones are most dangerous. There is a very good chance (but no certainty) that at least one lethal GRB took place during the past 5 gigayears close enough to… Expand
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
Astrobiological Effects of Gamma-Ray Bursts in the Milky Way Galaxy
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 surfaceExpand
Viewing Short Gamma-Ray Bursts From a Different Angle
The detection of a faint, short gamma-ray burst (GRB 170817A) in coincidence with the gravitational wave (GW 170817) detection by LIGO/Virgo is at odds with the expected known luminosity and redshiftExpand
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
Relative Likelihood for Life as a Function of Cosmic Time
Is life most likely to emerge at the present cosmic time near a star like the Sun? We address this question by calculating the relative formation probability per unit time of habitable Earth-likeExpand
Lethal Radiation from Nearby Supernovae Helps Explain the Small Cosmological Constant.
TLDR
The probability distribution of Λ is calculated using a model of cosmological galaxy formation, considering extinction of observers caused by radiation from nearby supernovae, and it is predicted that the authors are located on the edge of habitable regions about stellar density in the Galaxy, which may be tested by future exoplanet studies.

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
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 Resilience of Life to Astrophysical Events
TLDR
Surprisingly it is found that although human life is somewhat fragile to nearby events, the resilience of Ecdysozoa such as Milnesium tardigradum renders global sterilisation an unlikely event. Expand
Nitrate deposition following an astrophysical ionizing radiation event
TLDR
It is suggested that this flux may have contributed nutrients to this invasion if, as hypothesized, the end-Ordovician extinction event were initiated by a GRB or other ionizing radiation event. Expand

Did a gamma-ray burst initiate the late Ordovician mass extinction?
TLDR
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 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

GAMMA AND NEUTRINO RADIATION DOSE FROM GAMMA RAY BURSTS AND NEARBY SUPERNOVAE
TLDR
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 ionizing radiation and Earth: a brief review and census of intermittent intense sources.
TLDR
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.

Are Low-luminosity Gamma-Ray Bursts Generated by Relativistic Jets?
Low-luminosity gamma-ray bursts (ll-GRBs) constitute a subclass of GRBs that play a central role in the GRB-supernova connection. While ll-GRBs differ from typical long GRBs (LGRBs) in many aspects,Expand
Short-Duration Gamma-Ray Bursts
Gamma-ray bursts (GRBs) display a bimodal duration distribution with a separation between the short- and long-duration bursts at about 2 s. The progenitors of long GRBs have been identified asExpand

TLDR
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
