Near-Infrared Spectroscopy of Low-Redshift Palomar-Green Quasars and Composite Spectra

Amy Cavanaugh, Michael Brotherton, Jacob McLane +1

The Palomar-Green (PG) Quasars have been used extensively to establish the spectral properties of luminous active galactic nuclei (AGNs) at low redshifts in many wavebands, but not…

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…

Monitoring AGNs with H Asymmetry. V. Long-term Variation and Evolution of the Broad H Emission-Line Profiles

Feng-Na Fang, Pu Du, Michael S. Brotherton +40

The physical origins of the diverse emission-line asymmetries observed in the spectra of active galactic nuclei (AGNs) remain incompletely understood. Monitoring the temporal varia…

Gemini Near Infrared Spectrograph -- Distant Quasar Survey: Rest-Frame Ultraviolet-Optical Spectral Properties of Broad Absorption Line Quasars

Harum Ahmed, Ohad Shemmer, Brandon Matthews +12

We present the rest-frame ultraviolet-optical spectral properties of 65 broad absorption line (BAL) quasars from the Gemini Near Infrared Spectrograph-Distant Quasar Survey (GNIRS-…

Monitoring AGNs with H Asymmetry. IV. First Reverberation Mapping Results of 14 AGNs

T. E. Zastrocky, Michael S. Brotherton, Pu Du +41

We report first-time reverberation mapping results for 14 AGNs from the ongoing Monitoring AGNs with H Asymmetry campaign (MAHA). These results utilize optical spectra obtained…

Long-term multiwavelength monitoring and reverberation mapping of NGC 2617 during a changing-look event

V. L. Oknyansky, M. S. Brotherton, S. S. Tsygankov +32

We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC~2617 carried out from 2016 until 2022 and covering the wavelength range fr…
