  • CO kinematics unveil outflows plausibly driven by a young jet in the gigahertz peaked radio core of NGC 6328
    We report the detection of outflowing molecular gas in the center of the nearby (z = 0.014) massive radio galaxy NGC 6328. The radio core of the galaxy, PKS B1718-649, is identified as a gigahertz peaked spectrum source with a compact (2 pc) double radio lobe morphology. We used ALMA CO(2-1) and CO(3-2) observations at 100 pc resolution to study

  • Chemical abundances of 1111 FGK stars from the HARPS GTO planet search program. IV. Carbon and C/O ratios for Galactic stellar populations and planet hosts
    Context. To understand the formation and composition of planetary systems, it is essential to have insights into the chemical composition of their host stars. In particular, C/O elemental ratios are useful for constraining the density and bulk composition of terrestrial planets. Aims: We study the carbon abundances with a twofold objective. On the

  • Capturing the Physics of MaNGA Galaxies with Self-supervised Machine Learning
    As available data sets grow in size and complexity, advanced visualization tools enabling their exploration and analysis become more important. In modern astronomy, integral field spectroscopic galaxy surveys are a clear example of increasing high dimensionality and complex data sets, which challenges the traditional methods used to extract the

  • CanariCam Mid-infrared Drift Scanning: Improved Sensitivity and Spatial Resolution
    Ground-based mid-infrared (MIR) astronomical observations require the removal of the fast time variable components of (a) sky/background variation and (b) array background. Typically, this has been achieved through oscillating the telescope's secondary mirror a few times a second, a process termed "chopping." However, chopping reduces on-object

  • Black hole feeding and star formation in NGC 1808
    We report on Atacama Large Millimeter Array (ALMA) observations of CO(3−2) emission in the Seyfert2/starburst galaxy NGC 1808, at a spatial resolution of 4 pc. Our aim is to investigate the morphology and dynamics of the gas inside the central 0.5 kpc and to probe the nuclear feeding and feedback phenomena. We discovered a nuclear spiral of radius

  • Asteroseismology of iota Draconis and Discovery of an Additional Long-period Companion
    Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted transit depths. However, these giant host stars are also some of the brightest in the sky and so enable high signal-to-noise ratio follow-up measurements. Here, we report on new observations of
