First Co-spatial Comparison of Stellar, Neutral-, and Ionized-gas Metallicities in a metal-rich galaxy: M83
Svea Hernandez, Alessandra Aloisi, Bethan L. James +14
We carry out a comparative analysis of the metallicities from the stellar, neutral-gas, and ionized-gas components in the metal-rich spiral galaxy M83. We analyze spectroscopic obs…
Observations of the Disk/Jet Coupling of MAXI J1820+070 During its Descent to Quiescence
A. W. Shaw, R. M. Plotkin, J. C. A. Miller-Jones +8
Black hole X-ray binaries in the quiescent state (Eddington ratios typically 10) display softer X-ray spectra (photon indices ) compared to higher-luminosi…
The NANOGrav 12.5-Year Data Set: Monitoring Interstellar Scattering Delays
Jacob E. Turner, Maura A. McLaughlin, James M. Cordes +33
We extract interstellar scintillation parameters for pulsars observed by the NANOGrav radio pulsar timing program. Dynamic spectra for the observing epochs of each pulsar were used…
AGN Triality of Triple Mergers: Multi-wavelength Classifications
Adi Foord, Kayhan Gultekin, Jessie C. Runnoe +1
We present results from a multi-wavelength analysis searching for multiple AGN systems in nearby (z<0.077) triple galaxy mergers. Combining archival Chandra, SDSS, WISE, and VLA ob…
AGN Triality of Triple Mergers: Detection of Faint X-ray Point Sources
Adi Foord, Kayhan Gultekin, Jessie C. Runnoe +1
We present results from our X-ray analysis of the first systematic search for triple AGN in nearby (z<0.077) triple galaxy mergers. We analyze archival Chandra observations of 7 tr…
SCExAO/CHARIS Direct Imaging Discovery of a 20 au Separation, Low-Mass Ratio Brown Dwarf Companion to an Accelerating Sun-like Star
Thayne Currie, Timothy D. Brandt, Masayuki Kuzuhara +27
We present the direct imaging discovery of a substellar companion to the nearby Sun-like star, HD 33632 Aa, at a projected separation of 20 au, obtained with SCExAO/CHARIS i…
