    Forming Young Bulges within Existing Disks: Statistical Evidence for External Drivers

    Full text link
    Contrary to traditional models of galaxy formation, recent observations suggest that some bulges form within preexisting disk galaxies. Such late-epoch bulge formation within disks seems to be linked to disk gas inflow and central star formation, caused by either internal secular processes or galaxy mergers and interactions. We identify a population of galaxies likely to be experiencing active bulge growth within disks, using the criterion that the color within the half-light radius is bluer than the outer disk color. Such blue-centered galaxies make up >10% of star-forming disk galaxies within the Nearby Field Galaxy Survey, a broad survey designed to represent the natural diversity of the low-z galaxy population over a wide range of luminosities and environments. Blue-centered galaxies correlate at 99% confidence with morphological peculiarities suggestive of minor mergers and interactions. From this and other evidence, we argue that external drivers rather than internal secular processes probably account for the majority of blue-centered galaxies. We go on to discuss quantitative plausibility arguments indicating that blue-centered evolutionary phases may represent an important mode of bulge growth for most disk galaxies, leading to significant changes in bulge-to-disk ratio without destroying disks. If this view is correct, bulge growth within disks may be a natural consequence of the repeated galaxy mergers and interactions inherent in hierarchical galaxy formation.Comment: 18 pages including 12 figures, AJ, accepte

The main problems of studying the mobility and stable operation of nuclear power plants with modular reactors are revealed. A dynamic model was created in the MATLAB/ Simulink environment for the HTR-PM type nuclear power plant with two reactor modules for studying the basic laws governing reactor modules and coordinating modules. The obtained simulation results confirm the stable operation of the multi-module nuclear power plant during the stage-by-stage reduction of the power of the first and second modules. The high-temperature gas-cooled reactor is a reliable concept for the fourth generation modular reactor, which can be considered as the basic option for further development of the nuclear energy sector of Ukraine

    Ultra-deep Large Binocular Camera U-band Imaging of the GOODS-North Field: Depth vs. Resolution

    Get PDF
    We present a study of the trade-off between depth and resolution using a large number of U-band imaging observations in the GOODS-North field (Giavalisco et al. 2004) from the Large Binocular Camera (LBC) on the Large Binocular Telescope (LBT). Having acquired over 30 hours of data (315 images with 5-6 mins exposures), we generated multiple image mosaics, starting with the best atmospheric seeing images (FWHM ≲\lesssim0.8"), which constitute ∼\sim10% of the total data set. For subsequent mosaics, we added in data with larger seeing values until the final, deepest mosaic included all images with FWHM ≲\lesssim1.8" (∼\sim94% of the total data set). From the mosaics, we made object catalogs to compare the optimal-resolution, yet shallower image to the lower-resolution but deeper image. We show that the number counts for both images are ∼\sim90% complete to UABU_{AB} ≲26\lesssim26. Fainter than UABU_{AB}∼\sim 27, the object counts from the optimal-resolution image start to drop-off dramatically (90% between UABU_{AB} = 27 and 28 mag), while the deepest image with better surface-brightness sensitivity (ΞΌUAB\mu^{AB}_{U}≲\lesssim 32 mag arcsecβˆ’2^{-2}) show a more gradual drop (10% between UABU_{AB} ≃\simeq 27 and 28 mag). For the brightest galaxies within the GOODS-N field, structure and clumpy features within the galaxies are more prominent in the optimal-resolution image compared to the deeper mosaics. Finally, we find - for 220 brighter galaxies with UABU_{AB}≲\lesssim 24 mag - only marginal differences in total flux between the optimal-resolution and lower-resolution light-profiles to ΞΌUAB\mu^{AB}_{U}≲\lesssim 32 mag arcsecβˆ’2^{-2}. In only 10% of the cases are the total-flux differences larger than 0.5 mag. This helps constrain how much flux can be missed from galaxy outskirts, which is important for studies of the Extragalactic Background Light.Comment: 24 pages, 14 figures, submitted to PASP, comments welcom
