Supernovae anisotropy power spectrum
  We contribute another anisotropy study to this field of research using Type
Ia supernovae (SNe Ia). In this work, we utilise the power spectrum calculation
method and apply it to both the current SNe Ia data and simulation. Using the
Union2.1 data set at all redshifts, we compare the spectrum of the residuals of
the observed distance moduli to that expected from an isotropic universe
affected by the Union2.1 observational uncertainties at low multipoles. Through
this comparison we find a dipolar anisotropy with tension of less that
$2\sigma$ towards $l =171^\circ \pm 21^\circ$ and $b=-26^\circ \pm 28^\circ$
which is mainly induced by anisotropic spatial distribution of the SNe with $z
> 0.2$ rather than being a cosmic effect. Furthermore, we find a tension of
$\sim 4\sigma$ at $\ell=4$ between the two spectra. Our simulations are
constructed with the characteristics of the upcoming surveys like the Large
Synoptic Survey Telescope (LSST), which shall bring us the largest SNe Ia
collection to date. We make predictions for the amplitude of a possible dipolar
anisotropy that would be detectable by future SNe Ia surveys.
