Paschen-alpha Emission in the Gravitationally Lensed Galaxy SMM J163554.2+661225 (2009)
Papovich, Casey, Rudnick, Gregory, Rigby, Jane, Willmer, Christopher, Finkelstein, Steven, ...
We report the detection of the Paschen-alpha emission line in the z=2.515 galaxy SMM J163554.2+661225 using Spitzer spectroscopy. SMM J163554.2+661225 is a sub-millimeter-selected infrared...
Turning Back the Clock: Inferring the History of the Eight O'clock Arc (2009)
Finkelstein, Steven L., Papovich, Casey, Rudnick, Gregory, Egami, Eiichi, Floc'h, Emeric Le, Rieke, Marcia J., ...
We present the results from an optical and near-infrared spectroscopic study of the ultraviolet-luminous z = 2.73 galaxy, the 8 o'clock arc. Due to gravitational lensing, this galaxy is magnified by...
Freedman, Wendy L., Rigby, Jane, Madore, Barry F., Persson, S. E., Sturch, Laura, Mager, Violet
We present mid-infrared Period-Luminosity relations for Cepheids in the Local Group galaxy IC1613. Using archival IRAC imaging data from Spitzer we were able to measure single-epoch magnitudes for...
Madore, Barry F., Rigby, Jane, Freedman, Wendy L., Persson, S. E., Sturch, Laura, Mager, Violet
We present the first application of mid-infrared Period-Luminosity relations to the determination of a Cepheid distance beyond the Magellanic Clouds. Using archival IRAC imaging data on NGC 6822 from...
The Cepheid Period-Luminosity Relation at Mid-Infrared Wavelengths: II. Second-Epoch LMC Data (2008)
Madore, Barry F., Freedman, Wendy L., Rigby, Jane, Persson, S. E., Sturch, Laura, Major, Violet
We present revised and improved mid-infrared Period-Luminosity (PL) relations for Large Magellanic Cloud (LMC) Cepheids based on double-epoch data of 70 Cepheids observed by Spitzer at 3.6, 4.5, 5.8...
The Cepheid Period-Luminosity Relation at Mid-Infrared Wavelengths: I. First-Epoch LMC Data (2008)
Freedman, Wendy L., Madore, Barry F., Rigby, Jane, Persson, S. E., Sturch, Laura
We present the first mid-infrared Period-Luminosity (PL) relations for Large Magellanic Cloud (LMC) Cepheids. Single-epoch observations of 70 Cepheids were extracted from Spitzer IRAC observations at...
Spitzer view on the evolution of star-forming galaxies from z=0 to z~3 (2005)
Perez-Gonzalez, Pablo G., Rieke, George H., Egami, Eiichi, Alonso-Herrero, Almudena, Dole, Herve, Papovich, Casey, ...
We use a 24 micron selected sample containing more than 8,000 sources to study the evolution of star-forming galaxies in the redshift range from z=0 to z~3. We obtain photometric redshifts for most...
Studying Distant Infrared-Luminous Galaxies with Spitzer and Hubble (2004)
Papovich, Casey, Egami, Eiichi, Floc'h, Emeric Le, Perez-Gonzalez, Pablo, Rieke, George, Rigby, Jane, ...
New surveys with the Spitzer space telescope identify distant star-forming and active galaxies by their strong emission at far-infrared wavelengths, which provides strong constraints on these...
Millions of Single Cloud Weak MgII Systems (2001)
Churchill, Chris, Rigby, Jane, Charlton, Jane
We report on a population of absorption systems selected by the presence of very weak Mg II doublets. A sub-population of these systems are iron enriched and have near solar metallicities. This would...
