C++ what does <> tag mean [duplicate]

I have a line of code that I found, I had never seen this before.

auto pnt_header = mem::read<IMAGE_NT_HEADERS>(base + dos_header.e_lfanew);

I am confused what this right here does

<IMAGE_NT_HEADERS>

If anyone can tell me what this tag right here does, like what does <> do. I don't know what its called so I couldn't look it up.
