The Carnegie Supernova Project: Analysis of the First Sample of Low-Redshift Type-Ia Supernovae (2009)

Folatelli, Gaston, Phillips, M. M., Burns, Christopher R., Contreras, Carlos, Hamuy, Mario, Freedman, W. L., ...

We present the analysis of the first set of low-redshift Type Ia supernovae (SNe Ia) by the Carnegie Supernova Project. Well-sampled, high-precision optical (ugriBV) and near-infrared (NIR; YJHKs)...

The Carnegie Supernova Project: First Photometry Data Release of Low-Redshift Type Ia Supernovae (2009)

Contreras, Carlos, Hamuy, Mario, Phillips, M. M., Folatelli, Gaston, Suntzeff, Nicholas B., Persson, S. E., ...

The Carnegie Supernova Project (CSP) is a five-year survey being carried out at the Las Campanas Observatory to obtain high-quality light curves of ~100 low-redshift Type Ia supernovae in a...

The Carnegie Supernova Project: First Near-Infrared Hubble Diagram to z~0.7 (2009)

Freedman, Wendy L., Burns, Christopher R., Phillips, M. M., Wyatt, Pamela, Persson, S. E., Madore, Barry F., ...

The Carnegie Supernova Project (CSP) is designed to measure the luminosity distance for Type Ia supernovae (SNe Ia) as a function of redshift, and to set observational constraints on the dark energy...

The He-rich core-collapse supernova 2007Y: observations from x-ray to radio wavelengths (2009)

Stritzinger, Maximilian, Mazzali, P., Phillips, Mark M., Immler, Stefan, Soderberg, Alicia, Sollerman, Jesper, ...

A detailed study spanning approximately a year has been conducted on the Type Ib supernova (SN) 2007Y. Imaging was obtained from X-ray to radio wavelengths, and a comprehensive set of multi-band...

The He-rich core-collapse supernova 2007Y: Observations from X-ray to Radio Wavelengths (2009)

Stritzinger, Maximilian, Mazzali, Paolo, Phillips, Mark M., Immler, Stefan, Soderberg, Alicia, Sollerman, Jesper, ...

A detailed study spanning approximately a year has been conducted on the Type Ib supernova 2007Y. Imaging was obtained from X-ray to radio wavelengths, and a comprehensive set of multi-band...

A New Distance to The Antennae Galaxies (NGC 4038/39) Based on the Type Ia Supernova 2007sr (2008)

Schweizer, Francois, Burns, Christopher R., Madore, Barry F., Mager, Violet A., Phillips, M. M., Freedman, Wendy L., ...

Traditionally, the distance to NGC 4038/39 has been derived from the systemic recession velocity, yielding about 20 Mpc for H_0 = 72 km/s/Mpc. Recently, this widely adopted distance has been...

Theoretical Modeling of Weakly Lensed Polarized Radio Sources (2004)

Burns, Christopher R., Dyer, Charles C., Kronberg, Philipp P., Roser, Hermann-Josef

In this paper we present the theoretical basis for the modeling of weakly gravitationally lensed extended sources that are polarized. This technique has been used in the past to constrain the mass...

Theoretical modeling of weakly lensed polarized radio sources (2004)

Burns, Christopher R., Dyer, Charles C., Kronberg, Philipp P., Röser, Hermann-Josef

In this paper we present the theoretical basis for the modeling of weakly gravitationally lensed extended sources that are polarized. This technique has been used in the past to constrain the mass...

The DDO IVC Distance Project: Survey Description and the Distance to G139.6+47.6 (2003)

Burns, Christopher R., Tycner, Christopher, McClure, Megan, Blindert, Kris, McNaughton, Rosemary, Gladders, Michael D., ...

We present a detailed analysis of the distance determination for one intermediate Velocity Cloud (IVC G139.6+47.6) from the ongoing DDO IVC Distance Project. Stars along the line of sight to...

The DDO IVC Distance Project (1998)

Gladders, Michael D., Clarke, Tracy E., Burns, Christopher R., Attard, Allen, Casey, Michael P., Hamilton, Devon, ...

We present the first set of distance limits from the David Dunlap Observatory Intermediate Velocity Cloud (DDO IVC) distance project. Such distance measures are crucial to understanding the origins...

The David Dunlap Observatory IVC Distance Project: First Results (1998)

Clarke, T. E., Mallen-Ornelas, Gabriela, Sawicki, Marcin, Brodwin, Mark, McNaughton, Rosemary, Gladders, Michael D., ...

We present distance estimates to a set of high-latitude intermediate-velocity HI clouds. We explore some of the physical parameters that can be determined from these results, such as cloud mass,...

The Distance to the Draco Cloud (1998)

Gladders, Michael D., Clarke, T. E., Burns, Christopher R., Attard, A., Casey, M. P., Hamilton, Devon, ...

The understanding of the nature of intermediate and high velocity gas in the Milky Way is hampered by a paucity of distance estimates to individual clouds. A project has been started at the David...
