The evolution of the core rotation rate of red giant stars is a key parameter in understanding the stellar behavior in the late phases of stellar evolution. Thanks to the mixed-dipole modes, we can constrain the core rotation and internal rotational gradient as a star advances through the red-giant phase. This master thesis presents a pipeline

Superclusters are the largest massive structures in the cosmic web on tens to hundreds of megaparsecs (Mpc) scales. They are the largest assembly of galaxy clusters in the Universe. Apart from a few detailed studies of such structures, their evolutionary mechanism is still an open question. In order to address and answer the relevant questions, a

Spitzer Space Telescope observations of several quiescent black hole low mass X-ray binaries (LMXBs) have shown mid-infrared excesses above the emission of a companion star. The excess has been proposed to originate from either a relativistic jet or circumbinary disk. If the mid-IR originates in a jet, then it probes the region closest to the black
