Pim van Oirschot, Juliana Kwan, Geraint F. Lewis
Over the last nine years of cosmic microwave background observations, the Wilkinson Microwave Anisotropy Probe () results were consistent with a CDM cosmological model in…
Binary white dwarfs in the halo of the Milky Way
Pim van Oirschot, Gijs Nelemans, Silvia Toonen +4
Aims: We study single and binary white dwarfs in the inner halo of the Milky Way in order to learn more about the conditions under which the population of halo stars was born, such…

Geraint F. Lewis, Pim van Oirschot
It has recently been claimed that the Hubble Sphere represents a previously unknown limit to our view of the universe, with light we detect today coming from a proper distance less…
Through the Looking Glass: Why the "Cosmic Horizon" is not a horizon
Pim van Oirschot, Juliana Kwan, Geraint F. Lewis
The present standard model of cosmology, CDM, contains some intriguing coincidences. Not only are the dominant contributions to the energy density approximately of the same orde…
