Descripción
In this paper we are exploring the possibilities of 3D printing in the fabrication of mirrors for astronomy. Taking the advantages of 3D printing to solve the existing problems caused by traditional manufacturing, two proof-of- concept mirror fabrication strategies are investigated in this paper. The first concept is a deformable mirror with embedded actuator supports system to minimise errors caused by the bonding interfaces during mirror assembly. The second concept is the adaption of the Stress Mirror Polishing (SMP) technique to a variety of mirror shapes by implemented a printed thickness distribution on the back side of the mirror. Design investigations and prototypes plans are presented for both studies.

    Constraining the core-rotation rate along the red-giant evolution
    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

    Identification of Superclusters and their Properties in the Sloan Digital Sky Survey
    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

    Rapid multiwavelength variability reveals jet emission in the black hole binary V404 Cygni in quiescence
    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
