In the standard cosmological model, the merger remnant of the Milky Way and Andromeda (Milkomeda) will be the only galaxy remaining within our event horizon once the Universe has aged by another factor of ten, ~ 1011 years after the Big Bang. After that time, the only extragalactic sources of light in the observable cosmic volume will be hypervelocity stars being ejected continuously from Milkomeda. Spectroscopic detection of the velocity-distance relation or the evolution in the Doppler shifts…

The optimal cosmic epoch for precision cosmology
The statistical uncertainty in measuring the primordial density perturbations on a given comoving scale is dictated by the number of independent regions of that scale that are accessible to an
High-velocity stars from close interaction of a globular cluster and a supermassive black hole
Observations show the presence, in the halo of our Galaxy, of stars moving at velocities so high to require an acceleration mechanism involving the presence of a massive central black hole. Thus, in
Unbound particles in dark matter halos
We investigate unbound dark matter particles in halos by tracing particle trajectories in a simulation run to the far future (a = 100). We find that the traditional sum of kinetic and potential
Surviving in a metastable de Sitter space-time
A bstractIn a metastable de Sitter space any object has a finite life expectancy beyond which it undergoes vacuum decay. However, by spreading into different parts of the universe which will fall out
Understanding Our Only Universe
In an imaginary dialogue between a professor and a layman about the future of cosmology, the said professor relates the paradoxical story of scientist Zee Prime, a bold thinker of a future
Securing Fuel for Our Frigid Cosmic Future
Advanced civilizations will likely migrate into rich clusters of galaxies, which host the largest reservoirs of matter bound by gravity against the accelerated cosmic expansion.

This work attempts to construct a useful model for understanding the human deep future, and explores the potential deep futures of intelligence, and extrapolate towards two hypothetical versions of an “Omega Civilization”: Expansion and Transcension.

Hypervelocity stars from the Andromeda galaxy
Hypervelocity stars (HVSs) discovered in the Milky Way (MW) halo are thought to be ejected from near the massive black hole (MBH) at the Galactic centre. In this paper, we investigate the spatial and
Discovery of an Unbound Hypervelocity Star in the Milky Way Halo
We have discovered a star, SDSS J090745.0+024507, leaving the Galaxy with a heliocentric radial velocity of 853 ± 12 km s-1, the largest velocity ever observed in the Milky Way halo. The star is
The collision between the Milky Way and Andromeda
We use a N{body/hydrodynamic simulation to forecast the future encounter between the Milky Way and the Andromeda galaxies, given current observational constraints on their relative distance, relative
Probing the shape of the Galactic halo with hypervelocity stars
Precise proper-motion measurements (σμ ~ 10 μas yr-1) of the recently discovered hypervelocity star (HVS) SDSS J090745.0+024507 would yield significant constraints on the axis ratios and orientation
Long-term future of extragalactic astronomy
If the current energy density of the universe is indeed dominated by a cosmological constant, then high-redshift sources will remain visible to us only until they reach some finite age in their
Where are the old-population hypervelocity stars?
To date, all of the reported hypervelocity stars (HVSs), which are believed to be ejected from the Galactic center, are blue and therefore almost certainly young. Old-population HVSs could be much
The ultimate halo mass in a ΛCDM universe
In the far future of an acceleratingCDM cosmology, the cosmic web of large-scale structure consists of a set of increasingly isolated haloes in dynamical equilibrium. We examine the ap- proach of
The asymptotic form of cosmic structure : Small-scale power and accretion history
We explore the effects of small-scale structure on the formation and equilibrium of dark matter halos in a universe dominated by vacuum energy. We present the results of a suite of four N-body
