The NANOGrav 15 yr Data Set: Impacts of Customized Chromatic Noise Models on Gravitational Wave Analyses

Nikita Agarwal, Gabriella Agazie, Alessandra Amosso +120

We report updated nHz gravitational wave (GW) significance, characterization, and interpretations using the customized chromatic-noise models (CNMs) developed in Larsen, Baier et a…

The orientation dependence of quasar spectral energy distributions

Jessie Runnoe, Zhaohui Shang, Michael Brotherton

We investigate the orientation dependence of the spectral energy distributions in a sample of radio-loud quasars. Selected specifically to study orientation issues, the sample cont…

Does Size Matter? The Underlying Intrinsic Size Distribution of Radio Sources and Implications for Unification by Orientation

Michael A. DiPompeo, Jessie C. Runnoe, Adam D. Myers +1

Unification by orientation is a ubiquitous concept in the study of active galactic nuclei. A gold standard of the orientation paradigm is the hypothesis that radio galaxies and rad…

Rehabilitating CIV-based black hole mass estimates in quasars

J. C. Runnoe, M. S. Brotherton, Zhaohui Shang +1

Currently, the ability to produce black hole mass estimates using the CIV 1549 line that are consistent with Hb mass estimates is uncertain, due in large part to disagreement betwe…

Rest-frame optical properties of luminous, radio-selected, broad absorption line quasars

J. C. Runnoe, R. Ganguly, M. S. Brotherton +1

We have obtained IRTF/SpeX spectra of eight moderate-redshift (z=0.7-2.4), radio-selected (log R*~0.4-1.9) broad absorption line (BAL) quasars. The spectra cover the rest-frame opt…

An Infrared Excess Identified in Radio-Loud Broad Absorption Line Quasars

M. A. DiPompeo, J. C. Runnoe, M. S. Brotherton +1

If broad absorption line (BAL) quasars represent a high covering fraction evolutionary state (even if this is not the sole factor governing the presence of BALs), it is expected th…
