Stellar kinematics in blue compact galaxies (2009)
Cumming, Robert J., Östlin, Göran, Marquart, Thomas, Fathi, Kambiz, Bergvall, Nils, Adamo, Angela
In a programme of observations of local luminous blue compact galaxies (BCGs), we are investigating kinematics by using tracers of both stars and ionized gas. Here we summarise our program and...

Luminous blue compact galaxies, common at z~1 but now relatively rare, show disturbed kinematics in emission lines. As part of a programme to understand their formation and evolution, we have...
Dynamical masses of two young globular clusters in the blue compact galaxy ESO 338-IG04 (2006)
Ostlin, Goran, Cumming, Robert J., Bergvall, Nils
We present high-resolution echelle spectroscopy, obtained with the UVES spectrograph on ESO/VLT, of two luminous star clusters in the metal-poor blue compact galaxy ESO 338-IG04 at a distance of 37.5...
The type IIn supernova 1994W: evidence for the explosive ejection of a circumstellar envelope (2004)
Chugai, Nikolai N., Blinnikov, Sergei I., Cumming, Robert J., Lundqvist, Peter, Bragaglia, Angela, Filippenko, Alexei V., ...
We present and analyse spectra of the Type IIn supernova 1994W obtained between 18 and 203 days after explosion. During the luminous phase (first 100 d) the line profiles are composed of three major...
SN 1994W: evidence of explosive mass ejection a few years before explosion (2003)
Chugai, Nikolai N., Cumming, Robert J., Blinnikov, Sergei I., Lundqvist, Peter, Filippenko, Alexei V., Barth, Aaron J., ...
We present and analyse spectra of the Type IIn supernova 1994W obtained between 18 and 202 days after explosion. During the first 100 days the line profiles are composed of three major components:...
A very low mass of Ni-56 in the ejecta of SN 1994W (1997)
Sollerman, Jesper, Cumming, Robert J., Lundqvist, Peter
We present spectroscopic and photometric observations of the luminous narrow- line Type IIP (plateau) supernova 1994W. After the plateau phase (t >120 days), the light curve dropped by 3.5 mag in V...
Supernova progenitor constraints from circumstellar interaction: Type Ia (1996)
Lundqvist, Peter, Cumming, Robert J.
Searching for the presence of a circumstellar medium is a direct observational way to discriminate between different types of progenitor systems for Type Ia supernovae. We have modeled whether such...
Supernova progenitor constraints from circumstellar interaction: Type II (1996)
Cumming, Robert J., Lundqvist, Peter
All types of supernovae (SNe), except Type Ia, have been observed to interact with their immediate circumstellar medium (CSM). This interaction can reveal their progenitor's histories, and constrain...
A spectroscopic study of the progenitor of supernova 1987A / (1994)
Thesis (Ph. D.)--University of London, 1994.
Parton, Kevin A., Cumming, Robert J.
In this paper a description is provided of the development and use of a target-MOTAD model for use in consultative work with farmers who are under financial pressure. The analysis of downside risk...
