A Hubble diagram from Type II Supernovae based solely on photometry: the Photometric-Colour Method
T. de Jaeger, S. González-Gaitán, J. P. Anderson +20
We present a Hubble diagram of type II supernovae using corrected magnitudes derived only from photometry, with no input of spectral information. We use a data set from the Carnegi…
On the distance of the globular cluster M4 (NGC 6121) using RR Lyrae stars: II. Mid-infrared period-luminosity relations
J. R. Neeley, M. Marengo, G. Bono +12
New mid-infrared period-luminosity (PL) relations are presented for \rrl{} variables in the globular cluster M4 (NGC 6121). Accurate photometry was obtained for 37 \rrl{} variables…
Strong near-infrared carbon in the Type Ia supernova iPTF13ebh
E. Y. Hsiao, C. R. Burns, C. Contreras +51
We present near-infrared (NIR) time-series spectroscopy, as well as complementary ultraviolet (UV), optical, and NIR data, of the Type Ia supernova (SN Ia) iPTF13ebh, which was dis…
The Carnegie Hubble Program: The Distance and Structure of the SMC as Revealed by Mid-infrared Observations of Cepheids
Victoria Scowcroft, Wendy L. Freedman, Barry F. Madore +5
Using Spitzer observations of classical Cepheids we have measured the true average distance modulus of the SMC to be mag (corresponding to $6…
