First-year Sloan Digital Sky Survey-II (SDSS-II) Supernova Results: Hubble Diagram and Cosmological Parameters (2009)

Kessler, Richard, Becker, Andrew, Cinabro, David, Vanderplas, Jake, Frieman, Joshua A., Marriner, John, ...

We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04 < z < 0.42, discovered during the first season (Fall 2005) of the Sloan Digital Sky Survey-II...

The Sloan Digital Sky Survey-II: Photometry and Supernova Ia Light Curves from the 2005 data (2009)

Holtzman, Jon A., Marriner, John, Kessler, Richard, Sako, Masao, Dilday, Ben, Frieman, Joshua A., ...

We present ugriz light curves for 146 spectroscopically confirmed or spectroscopically probable Type Ia supernovae from the 2005 season of the SDSS-II Supernova survey. The light curves have been...

The peculiar periodic YSO WL 4 in ρ Ophiuchus (2008)

Plavchan, Peter, Gee, Alan H., Stapelfeldt, Karl, Becker, Andrew

We present the discovery of 130.87 day periodic near-infrared flux variability for the Class II T Tauri star WL 4 (=2MASS J16271848–2429059, ISO-Oph 128). Our data are from the 2MASS Calibration...

First-Year Spectroscopy for the SDSS-II Supernova Survey (2008)

Zheng, Chen, Romani, Roger W., Sako, Masao, Marriner, John, Bassett, Bruce, Becker, Andrew, ...

This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band light curves of...

Greensburg envisioned (2007)

Anterola, Jeremy, Becker, Andrew, Blackwell, Jessica, Bonser, Skyler, Capps, Scott, Curry, Collin, ...

May 4, 2007, a tornado ripped across Kiowa County, Kansas, leveling ninety-five percent of the town of Greensburg and leaving the rest of the town severely damaged. Shortly after the tornado, a...

Lightcurves of Type Ia Supernovae from Near the Time of Explosion (2006)

Garg, Arti, Stubbs, Christopher W., Challis, Peter, Wood-Vasey, W. Michael, Blondin, Stephane, Huber, Mark E., ...

We present a set of 11 type Ia supernova (SN Ia) lightcurves with dense, pre-maximum sampling. These supernovae (SNe), in galaxies behind the Large Magellanic Cloud (LMC), were discovered by the...

The Fall 2004 SDSS Supernova Survey (2005)

Sako, Masao, Romani, Roger, Frieman, Josh, Adelman-McCarthy, Jen, Becker, Andrew, DeJongh, Fritz, ...

In preparation for the Supernova Survey of the Sloan Digital Sky Survey (SDSS) II, a proposed 3-year extension to the SDSS, we have conducted an early engineering and science run during the fall of...

The Large-Scale Extinction Map of the Galactic Bulge from the MACHO Project Photometry (2003)

Popowski, Piotr, Cook, Kem, Becker, Andrew

We present a (V-R)-based reddening map of about 43 square degrees of the Galactic bulge/bar. The map is constructed using template image photometry from the MACHO microlensing survey, contains 9717...

Frequency Screening of First Stage Turbine Blades in the T56-A-7B Engine (1998)

Becker, Andrew, Marsden, Paul

Historically it has been difficult to obtain accurate and repeatable frequency data for the first bending mode of turbine blades. This report summarises the technique used by AMRL to screen first...

Measurement of the Natural Bending Modes of Rotors in the TF30 Engine (1998)

Shilo, Mark, Becker, Andrew

The natural bending modes of the high and low speed shafts from the TF3O engine were measured in order to provide an unequivocal reference for validation of 3D Finite Element models of the shafts....

A Replacement Database for the CH - 47D Spectrometric Oil Analysis Program (1998)

Marsden, Paul, Becker, Andrew

A Spectrometric Oil Analysis Program (SOAP) operates on selected Australian Defence Force platforms to assist in the prediction of incipient machinery failure. Historically, the data from the...

A Health Assessment of Lubricating Oil in Two Australian Army CH-47D Helicopters (1998)
