Principal component analysis of the Spitzer IRS spectra of ultraluminous infrared galaxies
Lingyu Wang, Duncan Farrah, Brian Connolly +4
We present the first principal component analysis (PCA) applied to a sample of 119 Spitzer Infrared Spectrograph (IRS) spectra of local ultraluminous infrared galaxies (ULIRGs) at…
The Hubble Space Telescope Cluster Supernova Survey: II. The Type Ia Supernova Rate in High-Redshift Galaxy Clusters
K. Barbary, G. Aldering, R. Amanullah +40
We report a measurement of the Type Ia supernova (SN Ia) rate in galaxy clusters at 0.9 < z < 1.45 from the Hubble Space Telescope (HST) Cluster Supernova Survey. This is the first…
The extraordinary mid-infrared spectral properties of FeLoBAL Quasars
D. Farrah, T. Urrutia, M. Lacy +7
We present mid-infrared spectra of six FeLoBAL QSOs at 1<z<1.8, taken with the Spitzer space telescope. The spectra span a range of shapes, from hot dust dominated AGN with silicat…
Reducing Zero-point Systematics in Dark Energy Supernova Experiments
L. Faccioli, A. G. Kim, R. Miquel +17
We study the effect of filter zero-point uncertainties on future supernova dark energy missions. Fitting for calibration parameters using simultaneous analysis of all Type Ia super…
