Hot UV-bright stars of galactic globular clusters
S. Moehler, W. B. Landsman, T. Lanz +1
We have performed a census of the UV-bright population in 78 globular clusters using wide-field UV telescopes. This population includes a variety of phases of post-horizontal branc…
Just how hot are the Centauri extreme horizontal branch pulsators?
M. Latour, S. K. Randall, P. Chayer +5
Past studies based on optical spectroscopy suggest that the five Cen pulsators form a rather homogeneous group of hydrogen-rich subdwarf O stars with effective temperatures of…
The Swift-UVOT ultraviolet and visible grism calibration
N. P. M. Kuin, W. Landsman, A. A. Breeveld +16
We present the calibration of the Swift UVOT grisms, of which there are two, providing low-resolution field spectroscopy in the ultraviolet and optical bands respectively. The UV g…
The Discovery of Pulsating Hot Subdwarfs in NGC 2808
Thomas M. Brown, Wayne B. Landsman, Suzanna K. Randall +2
We present the results of a Hubble Space Telescope program to search for pulsating hot subdwarfs in the core of NGC 2808. These observations were motivated by the recent discovery…
High-Velocity Line Forming Regions in the Type Ia Supernova 2009ig
G. H. Marion, Jozsef Vinko, J. Craig Wheeler +13
We report measurements and analysis of high-velocity (> 20,000 km/s) and photospheric absorption features in a series of spectra of the Type Ia supernova (SN) 2009ig obtained betwe…
Image Registration for Stability Testing of MEMS
Nargess Memarsadeghi, Jacqueline Le Moigne, Peter N. Blake +4
Image registration, or alignment of two or more images covering the same scenes or objects, is of great interest in many disciplines such as remote sensing, medical imaging, astron…
