Near-IR CO and CN in classical Cepheids
Scott G. Call, Thomas Griffith, Eric G. Hintz +4
We present medium resolution near-infrared spectral measurements of the carbon monoxide (CO) and the cyano radical (CN) features in 12 Galactic classical Cepheids. The pulsation pe…
CO Emission and Absorption-line Survey of the M87 Nucleus Using Archival ALMA Imaging
Benjamin D. Boizelle, Xueyi Li, Nicholas LeVar +5
We present an M87 molecular line search from archival Atacama Large Millimeter/sub-millimeter Array (ALMA) imaging, covering the circumnuclear disk (CND) as well as ionized gas fil…
Circumnuclear Dust in Luminous Early-Type Galaxies -- I. Sample Properties and Stellar Luminosity Models
Jared R. Davidson, Benjamin D. Boizelle, Jonelle L. Walsh +8
Dusty circumnuclear disks (CNDs) in luminous early-type galaxies (ETGs) show regular, dynamically cold molecular gas kinematics. For a growing number of ETGs, Atacama Large Millime…
Gas-dynamical Mass Measurements of the Supermassive Black Holes in the Early-Type Galaxies NGC 4786 and NGC 5193 from ALMA and HST Observations
Kyle M. Kabasares, Jonathan H. Cohn, Aaron J. Barth +10
We present molecular gas-dynamical mass measurements of the central black holes in the giant elliptical galaxies NGC 4786 and NGC 5193, based on CO(21) observations from the Ata…
