GALEX Spectroscopy of SN 2005ay suggests a UV spectral uniformity among type II-P supernovae
A. Gal-Yam, F. Bufano, T. Barlow +24
We present the first results from our GALEX program designed to obtain ultraviolet (UV) spectroscopy of nearby core-collapse supernovae (SNe). Our first target, SN 2005ay in the ne…
From Shock Breakout to Peak and Beyond: Extensive Panchromatic Observations of the Type Ib Supernova 2008D associated with Swift X-ray Transient 080109
Maryam Modjaz, W. Li, N. Butler +38
We present extensive early photometric (ultraviolet through near-infrared) and spectroscopic (optical and near-infrared) data on supernova (SN) 2008D as well as X-ray data analysis…
Observations of the Naked-Eye GRB 080319B: Implications of Nature's Brightest Explosion
J. S. Bloom, D. A. Perley, W. Li +18
The first gamma-ray burst (GRB) confirmed to be bright enough to be seen with the naked eye, GRB 080319B at redshift z = 0.937, allowed for exquisite follow-up observations across…
Constraining Cosmic Evolution of Type Ia Supernovae
Ryan J. Foley, A. V. Filippenko, C. Aguilera +27
We present the first large-scale effort of creating composite spectra of high-redshift type Ia supernovae (SNe Ia) and comparing them to low-redshift counterparts. Through the ESSE…
The properties of V838 Mon in 2002 November
Ya. V. Pavlenko, J. Th. van Loon, A. Evans +7
We present the results of modelling the 0.45--1 micron spectral energy distribution of V838 Mon for 2002 November. Synthetic spectra were calculated using the NextGen model atmosph…
A "Combination Nova" Outburst in Z Andromedae: Nuclear Shell Burning Triggered by a Disk Instability
J. L. Sokoloski, S. J. Kenyon, B. R. Espey +11
We describe observational evidence for a new kind of interacting-binary-star outburst that involves both an accretion instability and an increase in thermonuclear shell burning on…
Discovery and Evolution of an Unusual Luminous Variable Star in NGC 3432 (Supernova 2000ch)
R. M. Wagner, F. J. Vrba, A. A. Henden +15
We present photometric and spectroscopic observations of SN 2000ch, an unusual and extremely luminous variable star located in the galaxy NGC 3432. The object was discovered on 200…
Photometry and Spectroscopy of GRB 030329 and Its Associated Supernova 2003dh: The First Two Months
T. Matheson, P. M. Garnavich, K. Z. Stanek +4
We present extensive optical and infrared photometry of the afterglow of gamma-ray burst (GRB) 030329 and its associated supernova (SN) 2003dh over the first two months after detec…
Steps Toward Determination of the Size and Structure of the Broad-Line Region in Active Galactic Nuclei. XVI. A Thirteen-Year Study of Spectral Variability in NGC 5548
B. M. Peterson, the International AGN Watch
We present the final installment of an intensive 13-year study of variations of the optical continuum and broad H-beta emission line in the Seyfert 1 galaxy NGC 5548. The data base…
Outbursts of Classical Symbiotics: Multi-Wavelength Observations of the 2000-2001 Outburst of Z Andromedae
J. L. Sokoloski, S. J. Kenyon, A. K. H. Kong +11
We describe the first results from a program of multi-wavelength monitoring of symbiotic binary stars in outburst. The prototypical symbiotic star Z Andromedae was observed extensi…
Multiwavelength Monitoring of the Narrow-Line Seyfert 1 Galaxy Akn 564. III. Optical Observations and the Optical--UV--X-ray Connection
O. Shemmer, P. Romano, R. Bertram +36
We present the results of a two-year long optical monitoring program of the narrow-line Seyfert 1 galaxy Akn 564. The majority of this monitoring project was also covered by X-ray…
A High Peculiarity Rate for Type Ia SNe
W. D. Li, A. V. Filippenko, A. G. Riess +2
We have compiled a sample of 90 SNe Ia from 1997 to 1999 (up to SN 1999da) and studied the peculiarity rate of SN 1991T, SN 1991bg and SN 1986G-like objects. A Monte Carlo code is…
