The existence of a bullet cluster (such as 1E0657-56) poses a challenge to the concordance Lambda cold dark matter model. Here we investigate the velocity distribution of dark matter halo pairs in lar...

We revisit ghost dark matter, the possibility that ghost condensation may serve as an alternative to dark matter. In particular, we investigate the Friedmann-Robertson-Walker (FRW) background evolutio...

The premier alternative to the dark matter paradigm is modified gravity. Following an introduction to the relevant phenomenology of galaxies, I review the MOND paradigm, an effective summary of the ob...

We discuss the thermal evolution and Bose condensation of ultra-light scalar particles with Compton wavelength of galactic scales. We find an upper bound of 1.5 K for the dark matter temperature from ...
