AGN STORM 2. XII. Ground-Based Optical Photometry and Lag Measurements of Mrk 817
John W. Montano, Aaron J. Barth, Keith Horne +40
We present the ground-based imaging campaign and light curves of Markarian 817 as part of the multiwavelength monitoring program AGN STORM\,2. Observations were carried out over 1.…
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…
AGN STORM 2. XI. Spectroscopic reverberation mapping of the hot dust in Mrk 817
Hermine Landt, Benjamin D. Boizelle, Michael S. Brotherton +41
The AGN Space Telescope and Optical Reverberation Mapping 2 (STORM 2) campaign targeted Mrk 817 with intensive multi-wavelength monitoring and found its soft X-ray emission to be s…
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…
