Constraints on the outer radius of the broad emission line region of active galactic nuclei
Hermine Landt, Martin J. Ward, Martin Elvis +1
Here we present observational evidence that the broad emission line region (BELR) of active galactic nuclei (AGN) generally has an outer boundary. This was already clear for source…
A near-infrared relationship for estimating black hole masses in active galactic nuclei
Hermine Landt, Martin J. Ward, Bradley M. Peterson +4
Black hole masses for samples of active galactic nuclei (AGN) are currently estimated from single-epoch optical spectra using scaling relations anchored in reverberation mapping re…
The near-infrared broad emission line region of active galactic nuclei. II. The one-micron continuum
Hermine Landt, Martin Elvis, Martin J. Ward +3
We use quasi-simultaneous near-infrared (near-IR) and optical spectroscopy from four observing runs to study the continuum around 1 micron in 23 well-known broad-emission line acti…
Chandra Multiwavelength Project X-ray Point Source Catalog
Minsun Kim, Dong-Woo Kim, Belinda J. Wilkes +13
We present the Chandra Multiwavelength Project (ChaMP) X-ray point source catalog with ~6,800 X-ray sources detected in 149 Chandra observations covering \~10 deg^2. The full ChaMP…
Chandra X-Ray Observatory Observations of Neutron Stars: An Overview
M. C. Weisskopf, M. Karovska, G. G. Pavlov +2
We present a brief review of Chandra X-ray Observatory observations of neutron stars. The outstanding spatial and spectral resolution of this great observatory have allowed for obs…
Calibrating the Cepheid Period-Luminosity relation with the VLTI
M. Marengo, M. Karovska, D. Sasselov +3
The VLTI is the ideal instrument for measuring the distances of nearby Cepheids with the Baade-Wesselink method, allowing an accurate recalibration of the Cepheid Period-Luminosity…
