NuSTAR Spectroscopy of Multi-Component X-ray Reflection from NGC 1068

Franz E. Bauer, Patricia Arevalo, Dominic J. Walton +26

We report on observations of NGC1068 with NuSTAR, which provide the best constraints to date on its ~keV spectral shape. We find no strong variability over the past two decade…

The NuSTAR View of Nearby Compton-thick AGN: The Cases of NGC 424, NGC 1320 and IC 2560

M. Baloković, A. Comastri, F. A. Harrison +25

We present X-ray spectral analyses for three Seyfert 2 active galactic nuclei, NGC 424, NGC 1320, and IC 2560, observed by NuSTAR in the 3-79 keV band. The high quality hard X-ray…

NuSTAR unveils a Compton-thick Type 2 quasar in Mrk 34

P. Gandhi, G. B. Lansbury, D. M. Alexander +27

We present Nustar 3-40 keV observations of the optically selected Type 2 quasar (QSO2) SDSS J1034+6001 or Mrk 34. The high-quality hard X-ray spectrum and archival XMM-Newton data…

NuSTAR and XMM-Newton Observations of Luminous, Heavily Obscured, WISE-Selected Quasars at z ~ 2

D. Stern, G. B. Lansbury, R. J. Assef +30

We report on a NuSTAR and XMM-Newton program that has observed a sample of three extremely luminous, heavily obscured WISE-selected AGN at z~2 in a broad X-ray band (0.1 - 79 keV).…

NuSTAR J033202-2746.8: direct constraints on the Compton reflection in a heavily obscured quasar at z~2

A. Del Moro, J. R. Mullaney, D. M. Alexander +25

We report NuSTAR observations of NuSTAR J033202-2746.8, a heavily obscured, radio-loud quasar detected in the Extended Chandra Deep Field-South, the deepest layer of the NuSTAR ext…

NuSTAR Observations of Heavily Obscured Quasars at z ~ 0.5

G. B. Lansbury, D. M. Alexander, A. Del Moro +23

We present NuSTAR hard X-ray (3-79 keV) observations of three Type 2 quasars at z ~ 0.4-0.5, optically selected from the Sloan Digital Sky Survey (SDSS). Although the quasars show…
