We present detailed NLTE synthetic spectra of hydrodynamic SNe Ia models. We make no assumptions about the form of the spectrum at the inner boundary. We calculate both Chandrasekhar-mass...
Direct Analysis of Spectra of the Type Ic Supernova 1994I (2007)
Jennifer Millard, David Branch, E. Baron, Adam Fisher, A. V. Filippenko, R. P. Kirshner, ...
Synthetic spectra generated by the parameterized supernova synthetic-- spectrum code SYNOW are compared to observed photospheric--phase spectra of the Type Ic supernova 1994I. The observed optical...
ON VAN DEN BERGH'S METHOD FOR MEASURING THE HUBBLE CONSTANT FROM TYPE IA SUPERNOVAE (2007)
David Branch, Adam Fisher, E. Baron, Peter Nugent
In a recent Letter, van den Bergh used explosion--model light--curve calculations of Hoflich & Khokhlov to calibrate the Hamuy et al. sample of remote Type Ia supernovae (SNe Ia), and obtained...

A Wavelength Multiplexed Bidirectional Fiber Ring Network (1998)
In this project, an eight-node optical fiber ring network was built that functions as a precursor to a local area network. The network uses four wavelength division multiplexed (WDM) channels and...
New Insight into the Spatial Distribution of Novae in M31 (1997)
Hatano, Kazuhito, Branch, David, Fisher, Adam, Starrfield, Sumner
We use a Monte Carlo technique together with a simple model for the distribution of dust in M31 to investigate the observability and spatial distribution of classical novae in M31.
Type Ia Supernovae as Extragalactic Distance Indicators (1997)
David Branch, Peter Nugent, Adam Fisher
Because Type Ia supernovae (SNe Ia) are not perfect standard candles, it is important to be able to use distance--independent observables (DIOs) to define subsets of SNe Ia that are "nearly...
Low Hubble Constant from Type Ia Supernovae by van den Bergh's Method (1996)
Branch, David, Fisher, Adam, Baron, E., Nugent, Peter
An interesting way to calibrate the absolute magnitudes of remote Type Ia supernovae (SNe Ia) that are well out in the Hubble flow, and thus determine the value of the Hubble constant, H_0, has been...
Type Ia Supernovae as Extragalactic Distance Indicators (1996)
Branch, David, Nugent, Peter, Fisher, Adam
Because Type Ia supernovae (SNe Ia) are not perfect standard candles, it is important to be able to use distance-independent observables (DIOs) to define subsets of SNe Ia that are ``nearly standard...
