Magnetic field geometry of the gamma-ray binary PSR B1259-63 revealed via X-ray polarization

Philip Kaaret, Oliver J. Roberts, Steven R. Ehlert +6

Some X-ray binaries containing an energetic pulsar in orbit around a normal star accelerate particles to high energies in the shock cone formed where the pulsar and stellar winds c…

X-ray Polarization of the Eastern Lobe of SS 433

Philip Kaaret, Riccardo Ferrazzoli, Stefano Silvestri +103

How astrophysical systems translate the kinetic energy of bulk motion into the acceleration of particles to very high energies is a pressing question. SS 433 is a microquasar that…

The XMM-SERVS survey: XMM-Newton point-source catalogs for the W-CDF-S and ELAIS-S1 fields

Q. Ni, W. N. Brandt, C. -T. Chen +30

We present the X-ray point-source catalogs in two of the XMM-Spitzer Extragalactic Representative Volume Survey (XMM-SERVS) fields, W-CDF-S (4.6 deg) and ELAIS-S1 (3.2 deg)…

Chandra Observations of Excess Fe K Line Emission in Galaxies with High Star Formation Rates: X-ray Reflection on Galaxy Scales?

Wei Yan, Ryan C. Hickox, Chien-Ting J. Chen +4

In active galactic nuclei (AGN), fluorescent Fe K (iron) line emission is generally interpreted as originating from obscuring material around a supermassive black hole (SMBH) on…

Observational Evidence for Enhanced Black Hole Accretion in Giant Elliptical Galaxies

Michael McDonald, Brian R. McNamara, Michael S. Calzadilla +5

We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live a…

A Large Population of Luminous Active Galactic Nuclei Lacking X-ray Detections: Evidence for Heavy Obscuration?

Christopher M. Carroll, Ryan C. Hickox, Alberto Masini +5

We present a large sample of infrared-luminous candidate active galactic nuclei (AGNs) that lack X-ray detections in Chandra, XMM-Newton, and NuSTAR fields. We selected all optical…
