Testing the Blazar Paradigm: ASCA Observations of FSRQs with Steep Soft X-ray Spectra

Rita M. Sambruna, Lester L. Chou, C. Megan Urry

We present the first observations at medium-hard X-rays with ASCA in 1998 August--November of four Flat Spectrum Radio Quasars (FSRQs), characterized by unusually steep soft X-ray…

Understanding Blazar Jets Through Their Multifrequency Emission

Rita M. Sambruna

Being dominated by non-thermal (synchrotron and inverse Compton) emission from a relativistic jet, blazars offer important clues to the structure and radiative processes in extraga…

Coordinated RXTE and multiwavelength observations of blazars

Rita M. Sambruna

Results from recent multiwavelength observations of blazars are reviewed, with particular emphasis on those involving the Rossi X-ray Timing Explorer (RXTE). I discuss blazars' spe…

Radio-loud AGNs: The X-ray perspective

Rita M. Sambruna, Michael Eracleous

The X-ray emission of radio-loud (RL) AGNs is a powerful tool for probing the structure of the accretion flow in these objects. We review recent spectral and variability studies of…

Constraining the central engine of radio-loud AGNs

Rita M. Sambruna, Michael Eracleous, Richard Mushotzky

We present an X-ray spectral survey of radio-loud (RL) AGNs using ASCA and RXTE. The goal was to study the structure of their central engines and compare it to that of their radio-…

X-rays from the Highly Polarized Broad Absorption Line QSO CSO 755

W. N. Brandt, A. Comastri, S. C. Gallagher +3

We present results from a BeppoSAX observation of the BAL QSO CSO 755, observed as part of our program to investigate the X-ray properties of highly polarized BAL QSOs. CSO 755 is…

An X-ray Spectral Survey of Radio-Loud AGN With ASCA

R. M. Sambruna, M. Eracleous, R. F. Mushotzky

We present a uniform and systematic analysis of the 0.6-10 keV X-ray spectra of radio-loud active galactic nuclei (AGN) observed by ASCA. The sample 10 BLRGs, 5 QSRs, 9 NLRGs, and…

Exploratory ASCA Observations of Broad Absorption Line Quasi-Stellar Objects

S. C. Gallagher, W. N. Brandt, R. M. Sambruna +2

We present the analysis and interpretation of a sample of eight ASCA observations of Broad Absorption Line Quasi-Stellar Objects (BALQSOs). This is the first moderate-sized sample…
