Tracing Interstellar Gas in Quiescent Galaxies Using Na I D and Ca II H&K Absorption

Arian Moghni, Timothy M. Heckman, Namrata Roy +3

For over two decades, Na I D ( Å) absorption has been the primary optical tracer of cool, neutral gas in galaxies. In contrast, Ca II H&K (3934.78, 39…

Galactic Rain: Cool Gas Inflows in Red Geyser Galaxies and Their Connection to AGN Activity and Interactions

Arian Moghni, Namrata Roy, Timothy M. Heckman +3

Red geysers are a population of massive (log[M/M]~10.5), quiescent galaxies that exhibit large-scale but weak, bi-symmetric ionized gas outflows, interpreted as signatures…

Predicting Resolved Dust Attenuation from Local Galaxy Properties Using MaNGA

Anilkumar Mailvaganam, Tayyaba Zafar, Pablo Corcho-Caballero +4

Accurate spatially resolved dust corrections are critical for interpreting the structure and evolution of star-forming galaxies (SFGs). We present an empirical model for predicting…

The Keck/DEIMOS Stellar Archive: I. Uniform Velocities and Metallicities for 78 Milky Way Dwarf Galaxies and Globular Clusters

Marla Geha, Debora Pelliccia, J. Xavier Prochaska +5

We present a homogeneous spectroscopic dataset of 22,339 stars in 78 Milky Way dwarf galaxy satellites and globular clusters. All data were taken with the Keck II telescope and Dee…

The Eddington Ratio Distribution of Narrow Line Active Galactic Nuclei

Michael R. Blanton, Arjun Suresh, Kyle B. Westfall +2

We measure the Eddington ratio distribution of local optical narrow-line active galactic nuclei (AGN) as a function of host galaxy properties, as a potential test of galaxy formati…

Robust support for semi-automated reductions of Keck/NIRSPEC data using PypeIt

Adolfo S. Carvalho, Greg Doppmann, Kyle B. Westfall +7

We present a data reduction pipeline (DRP) for Keck/NIRSPEC built as an addition to the PypeIt Python package. The DRP is capable of reducing multi-order echelle data taken both be…

The Future of Astronomical Data Infrastructure: Meeting Report

Michael R. Blanton, Janet D. Evans, Dara Norman +69

The astronomical community is grappling with the increasing volume and complexity of data produced by modern telescopes, due to difficulties in reducing, accessing, analyzing, and…

Ground Layer Adaptive Optics for the W. M. Keck Observatory: Feasibility Study

J. R. Lu, M. Chun, S. M. Ammons +12

Ground-layer adaptive optics (GLAO) systems offer the possibility of improving the "seeing" of large ground-based telescopes and increasing the efficiency and sensitivity of observ…
