First results from MIRI verification model testing (2008)
Lim, Tanya, Alvarez, Jose L., Bauwens, Eva, Garcia Bedregal, Alejandro, Blommaert, Joris, Dannerbauer, Helmut, ...
The Mid-Infrared Instrument (MIRI) is one of the three scientific instruments to fly on the James Webb Space Telescope (JWST), which is due for launch in 2013. MIRI contains two sub-instruments, an...
SDSSJ102111.02+491330.4: A Newly Discovered Gravitationally Lensed Quasar (2005)
Pindor, Bart, Eisenstein, Daniel J., Gregg, Michael D., Becker, Robert H., Inada, Naohisa, Oguri, Masamune, ...
We report follow-up observations of two gravitational lens candidates identified in the Sloan Digital Sky Survey (SDSS) dataset. We have confirmed that SDSS J102111.02+491330.4 is a previously...
Discovering Gravitational Lenses Through Measurements Of Their Time Delays (2005)
We consider the possibility that future wide-field time-domain optical imaging surveys may be able to discover gravitationally lensed quasar pairs through serendipitous measurements of their time...
SDSS J115517.35+634622.0: A Newly Discovered Gravitationally Lensed Quasar (2003)
Pindor, Bart, Eisenstein, Daniel J., Inada, Naohisa, Gregg, Michael D., Becker, Robert H., Brinkmann, Jon, ...
We report the discovery of SDSSJ115517.35+634622.0, a previously unknown gravitationally lensed quasar. The lens system exhibits two images of a $z = 2.89$ quasar, with an image separation of...
Determining the Lensing Fraction of SDSS Quasars: Methods and Results from the EDR (2003)
Pindor, Bart, Turner, Edwin L., Lupton, Robert H., Brinkmann, J.
We present an algorithm for selecting gravitational lens candidates from amongst Sloan Digital Sky Survey (SDSS) quasars. In median Early Data Release (EDR) conditions, the algorithm allows for the...
PMN J1632-0033: A new gravitationally lensed quasar (2001)
Winn, Joshua N., Morgan, Nicholas D., Hewitt, Jacqueline N., Kochanek, Christopher S., Lovell, James E. J., Patnaik, Alok R., ...
We report the discovery of a gravitationally lensed quasar resulting from our survey for lenses in the southern sky. Radio images of PMN J1632-0033 with the VLA and ATCA exhibit two compact,...
OGLE Cepheids have Lower Amplitudes in SMC than in LMC (2000)
Paczynski, Bohdan, Pindor, Bart
We selected cepheids from the OGLE database for the Magellanic Clouds in the period range 10^{1.1} < P < 10^{1.4} days. There were 33 objects in the LMC and 35 in the SMC. We find that the median...
