We deploy a wide range of methods to achieve this goal, including cutting-edge instrumentation, high-fidelity simulations, machine learning, multi-wavelength observations, sophisticated data analysis techniques, and theoretical modeling. Together, we hope to bring both a broad perspective and deep expertise to tackling the hardest questions in cosmology today.<\/p>\n<p>BU Cosmology is an Inter-Departmental Effort between Astronomy, Physics, and Computing &amp; Data Science.
