Feeding versus Feedback in NGC 4151 probed with Gemini NIFS. I. Excitation
T. Storchi-Bergmann, P. J. McGregor, Rogemar A. Riffel +3
We have used the Gemini Near-infrared Integral Field Spectrograph (NIFS) to map the emission-line intensity distributions and ratios in the Narrow-Line Region (NLR) of the Seyfert…
A photometric study of the southern Blazhko star SS For Unambiguous detection of quintuplet components
Katrien Kolenberg, Elisabeth Guggenberger, Thebe Medupe +6
We present our analysis of photometric data in the Johnson B and V filter of the southern Blazhko star SS For. In parallel, we analyzed the V observations obtained with the ASAS-3…
MRC B0319-454: Probing the large-scale structure with a giant radio galaxy
V. Safouris, R. Subrahmanyan, G. V. Bicknell +1
We present an investigation of the relationships between the radio properties of a giant radio galaxy MRC B0319-454 and the surrounding galaxy distribution with the aim of examinin…
Spectroscopy of High-Redshift Supernovae from the ESSENCE Project: The First Four Years
R. J. Foley, T. Matheson, S. Blondin +23
We present the results of spectroscopic observations from the ESSENCE high-redshift supernova (SN) survey during its first four years of operation. This sample includes spectra of…
Lithium abundances of halo dwarfs based on excitation temperature. I. LTE
A. Hosford, S. G. Ryan, A. E. Garcia Perez +2
The discovery of the Spite plateau in the abundances of 7Li for metal-poor stars led to the determination of an observationally deduced primordial lithium abundance. However, after…
The Keck Aperture Masking Experiment: spectro-interferometry of 3 Mira Variables from 1.1 to 3.8 microns
H. C. Woodruff, M. J. Ireland, P. G. Tuthill +6
We present results from a spectro-interferometric study of the Miras o Cet, R Leo and W Hya obtained with the Keck Aperture Masking Experiment from 1998 Sep to 2002 Jul. The spectr…
