Are there instruments that can detect stars and galaxies that lie along the plane of our galaxie on the other side of the center bulge? It seems like there should be a lot of material there that lies hidden from our view.

IR astronomy. NASA has published a map taken by the WISE space IR telescope.

^ What he said. Occlusion is much worse at some wavelengths than others. Infrared allows us to see much that is obscured in the visible spectrum.

I cannot remember what it's called but there is a dwarf galaxy orbiting the Milky Way, currently on the opposite side, that was detected with infrared.

This is the observable universe and Milky way makes these pointed dark zones for our observation even with IR technology:

That's what I remember seeing from the IR map, a big chunk of the universe is hiding behind the center bulge of the Milky Way. After all the stars at our galactic core are IR sources too so they blank out anything behind them.

Since the universal material distribution is similar everywhere behind those 2 slice of dark pizzas expect similar galaxies spreading. ;)
