Tomsick, John A., Gelino, Dawn M., Kaaret, Philip
The X-ray transient, 4U 1730-22, has not been detected in outburst since 1972, when a single outburst was detected by the Uhuru satellite. This neutron star or black hole X-ray binary is presumably...
The UCSD Radio-Selected Quasar Survey for Damped Lyman alpha System (2006)
Jorgenson, Regina A., Wolfe, Arthur M., Prochaska, Jason X., Lu, Limin, Howk, J. Christopher, Cooke, Jeff, ...
As large optical quasar surveys for damped Lya become a reality and the study of star forming gas in the early Universe achieves statistical robustness, it is now vital to identify and quantify the...
The Inclination Angle of and Mass of the Black Hole in XTE J1118+480 (2006)
Gelino, Dawn M., Balman, Solen, Kizilouglu, Umit, Yilmaz, Arda, Kalemci, Emrah, Tomsick, John A.
We have obtained optical and infrared photometry of the quiescent soft X-ray transient XTE J1118+480. In addition to optical and J-band variations, we present the first observed H- and K_s-band...
The Low Quiescent X-Ray Luminosity of the Transient X-Ray Burster EXO 1747-214 (2005)
Tomsick, John A., Gelino, Dawn M., Kaaret, Philip
We report on X-ray and optical observations of the X-ray burster EXO 1747-214. This source is an X-ray transient, and its only known outburst was observed in 1984-1985 by the EXOSAT satellite. We...
The Low Quiescent X-Ray Luminosity of the Neutron Star Transient XTE J2123-058 (2004)
Tomsick, John A., Gelino, Dawn M., Halpern, Jules P., Kaaret, Philip
We report on the first X-ray observations of the neutron star soft X-ray transient (SXT) XTE J2123-058 in quiescence, made by Chandra and BeppoSAX, as well as contemporaneous optical observations. In...
Gelino, Dawn M., Harrison, Thomas E., Orosz, Jerome A.
We have obtained optical and infrared photometry of the soft x-ray transient prototype V616 Mon (A0620-00). From this photometry, we find a spectral type of K4 for the secondary star in the system,...
Gelino, Dawn M., Harrison, Thomas E., McNamara, Bernard J.
We have obtained infrared photometry for the soft x-ray transient GU Mus. We present J and K_s band light curves modeled with WD98, the newest version of the Wilson-Devinney light curve modeling...
Infrared Observations of AR Ursae Majoris: Modeling the Ellipsoidal Variations (2000)
Howell, Steve B., Gelino, Dawn M., Harrison, Thomas E.
We have obtained time-series infrared photometry for the highly magnetic cataclysmic variable AR UMa. Our J and K' band observations occurred during a low state and they show a distinctive...
