    Examining the self-interaction of dark matter through central cluster galaxy offsets
    While collisionless cold dark matter models have been largely successful in explaining a wide range of observational data, some tensions still exist, and it...

    Extracting cosmological information from the angular power spectrum of the 2MASS Photometric Redshift catalogue
    Using the almost all-sky 2MASS Photometric Redshift catalogue (2MPZ) we perform for the first time a tomographic analysis of galaxy angular clustering in the...
