Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint objects, a flexibly-pointed instrument capable of high astrometric accur

Heating of galactic gas by dark matter annihilation in ultracompact minihalos

Autor: Clark, Hamish A., Iwanus, Nikolas, Elahi, Pascal J., Lewis, Geraint F., Scott, Pat

Publikováno v: JCAP 05 (2017) 048

The existence of substructure in halos of annihilating dark matter would be expected to substantially boost the rate at which annihilation occurs. Ultracompact minihalos of dark matter (UCMHs) are one of the more extreme examples of this. The boosted

Ultracompact minihalos as probes of inflationary cosmology

Autor: Aslanyan, Grigor, Price, Layne C., Adams, Jenni, Bringmann, Torsten, Clark, Hamish A., Easther, Richard, Lewis, Geraint F., Scott, Pat

Publikováno v: Phys. Rev. Lett. 117, 141102 (2016)

Cosmological inflation generates primordial density perturbations on all scales, including those far too small to contribute to the cosmic microwave background. At these scales, isolated ultracompact minihalos of dark matter can form well before stan

Investigating dark matter substructure with pulsar timing: I. Constraints on ultracompact minihalos

Autor: Clark, Hamish A., Lewis, Geraint F., Scott, Pat

Small-scale dark matter structure within the Milky Way is expected to affect pulsar timing. The change in gravitational potential induced by a dark matter halo passing near the line of sight to a pulsar would produce a varying delay in the light trav
