Currently having problems with alignment of equations, I've checked multiple other threads and tried multiple methods to no avail. I'm sure it's a simple fix though.
I'm aware my code is also not the prettiest, I'm pretty new to Latex.
\begin{alignat*}{2}
\delta^{s(0)}_{\ell m}(k) &= \delta_{\ell m}(k) &&= \sqrt{\frac{2}{\pi}}\int_0^\infty dr\, r^2\, \int d\Omega \delta(r, \Omega)k \, j_\ell(kr)Y^\ast_{\ell m} (\Omega) \\
&&= i^\ell k \int d\Omega \,\delta(k, \Omega) \,Y^\ast_{\ell m}(\Omega) \\
\delta^{s(1)}_{\ell m}(k) &= \sqrt{\frac{2}{\pi}} \int_0^\infty dr \, r^2 \, \int d\Omega[1+\delta(r, \Omega]\frac{\mathbf{v(r)}\cdot\Omega}{aH}k^2 j'_\ell(kr)Y^\ast_{\ell m}(\Omega)
\end{alignat*}
As you can see I would like the two equations with one & to align at one point, and the equations with the double && to align at a different point. However my code is displaying this
It seems the equations with one & have aligned correctly but I can't get the others to align. I've also tried using &{}={}& and &&=& as I've also seen those used, but had no luck.
!!!EDIT!!!:
Following the first comment, I'd like to clarify I'd like the equation to align similarly to below but with the second line aligned with the second = on the first line.
