"Dark matter" in accretion disks (2008)
Howell, Steve B., Hoard, D. W., Brinkworth, C., Kafka, S., Walentosky, M. J., Walter, Frederick M., ...
Using Spitzer Space Telescope photometric observations of the eclipsing, interacting binary WZ Sge, we have discovered that the accretion disk is far more complex than previously believed. Our 4.5...
The Rosette Eye: the key transition phase in the birth of a massive star (2008)
Li, J. Z., Smith, M. D., Gredel, R., Davis, C. J., Rector, T. A.
Massive protostars dramatically influence their surroundings via accretion-induced outflows and intense radiation fields. They evolve rapidly, the disk and infalling envelope being evaporated and...
"Dark Matter" in Accretion Disks (2008)
Howell, Steve B., Hoard, D. W., Brinkworth, C., Walter, Frederick M., Rector, T. A.
Using Spitzer Space Telescope photometric observations of the eclipsing, interacting binary WZ Sge, we have discovered that the accretion disk is far more complex than previously believed. Our 4.5...
Fast transition between Classical and Weak lined T Tauri stars due to external UV dissipation (2007)
The discovery of optical jets immersed in the strong UV radiation field of the Rosette Nebula sheds new light on, but meanwhile poses challenges to, the study of externally irradiated jets. The jet...
The 2dF BL Lac Survey II (2006)
Londish, D., Croom, S. M., Heidt, J., Boyle, B. J., Sadler, E. M., Whiting, M., ...
We report on our further analysis of the expanded and revised sample of potential BL Lac objects (the 2BL) optically identified from two catalogues of blue-selected (UV excess) point sources, the 2dF...
Faint Radio Sources in the NOAO Bootes Field. VLBA Imaging and Optical Identifications (2005)
Wrobel, J. M., Taylor, G. B., Rector, T. A., Myers, S. T., Fassnacht, C. D.
As a step toward investigating the parsec-scale properties of faint extragalactic radio sources, the Very Long Baseline Array (VLBA) was used at 5.0 GHz to obtain phase-referenced images of 76...
Image-Processing Techniques for the Creation of Presentation-Quality Astronomical Images (2004)
Rector, T. A., Levay, Z. G., Frattare, L. M., English, J., Pu'uohau-Pummill, K.
The quality of modern astronomical data, the power of modern computers and the agility of current image-processing software enable the creation of high-quality images in a purely digital form. The...
Active Galaxies at Milliarcsecond Resolution in the NOAO Deep Wide-Field Survey (2004)
Wrobel, J. M., Rector, T. A., Taylor, G. B., Myers, S. T., Fassnacht, C. D.
We are using the NRAO VLBA at 5.0 GHz to image about 200 FIRST sources stronger than 10 mJy at 1.4 GHz in the NDWFS.
XMM-Newton observations of the BL Lac MS0205.7+3509: a dense, low-metallicity absorber (2004)
Watson, D., McBreen, B., Hanlon, L., Reeves, J. N., Smith, N., Perlman, E., ...
The high-frequency-peaked BL Lac, MS0205.7+3509 was observed twice with XMM-Newton. Both X-ray spectra are synchrotron-dominated, with mean 0.2--10keV fluxes of 2.80+/-0.01 and 3.34+/-0.02 E-12...
A Search for Intraday Variability in the Blazar PKS 2005-489 (2003)
Rapid, multi-color optical monitoring carried out for a multiwavelength campaign during 22-27 August 2000 is presented for the bright and variable BL Lac object PKS 2005-489. Previous multiwavelength...
The Radio Structure of High-Energy Peaked BL Lacertae Objects (2003)
Rector, T. A., Gabuzda, D. C., Stocke, J. T.
We present VLA and first-epoch VLBA observations that are part of a program to study the parsec-scale radio structure of a sample of fifteen high-energy-peaked BL Lacs (HBLs). The sample was chosen...
While BL Lacertae objects are widely believed to be highly beamed, low-luminosity radio galaxies, many radio-selected BL Lacs have extended radio power levels and optical emission lines that are too...
Surveys and the Blazar Parameter Space (2000)
Perlman, E. S., Padovani, P., Landt, H., Stocke, J. T., Costamente, L., Rector, T. A., ...
The rareness of blazars, combined with the previous history of relatively shallow, single-band surveys, has dramatically colored our perception of these objects. Despite a quarter-century of...
The Properties of the X-Ray-Selected EMSS Sample of BL Lac Objects (2000)
Rector, T. A., Stocke, J. T., Perlman, E. S., Morris, S. L., Gioia, I. M.
We present updated and complete radio, optical and X-ray data for BL Lacs in the Einstein Medium Sensitivity Survey (EMSS). The complete "M91" sample first presented in Morris et al. is updated to...
