Long-term optical monitoring of TeV emitting Blazars

K. Nilsson, E. Lindfors, L. O. Takalo +17

We present 10 years of R-band monitoring data of 31 northern blazars which were either detected at very high energy (VHE) gamma rays or listed as potential VHE gamma-ray emitters.…

MAGIC observations and multifrequency properties of the Flat Spectrum Radio Quasar 3C 279 in 2011

J. Aleksić, S. Ansoldi, L. A. Antonelli +168

We study the multifrequency emission and spectral properties of the quasar 3C 279. We observed 3C 279 in very high energy (VHE, E>100GeV) gamma rays, with the MAGIC telescopes duri…

Spectropolarimetric observations of cool DQ white dwarfs

Tommi Vornanen, Svetlana Berdyugina, Andrei Berdyugin

Following our recent discovery of a new magnetic DQ white dwarf (WD) with CH molecular features, we report the results for the rest of the DQ WDs from our survey. We use high signa…

Open Science Project in White Dwarf Research

Tommi Vornanen

I will propose a new way of advancing white dwarf research. Open science is a method of doing research that lets everyone who has something to say about the subject take part in th…

Observations and Modelling of DQ White Dwarfs

Tommi Vornanen, Svetlana Berdyugina, Andrei Berdyugin

We present spectropolarimetric observations and modelling of 12 DQ white dwarfs. Modelling is based on the method presented in Berdyugina et al. (2005). We use the model to fit the…

Photometry of two DQ white dwarfs - search for spots

Tommi Vornanen, Andrei Berdyugin

Aims. The intensity profiles of the C_2 Swan bands in cool DQ white dwarfs cannot be adequately fitted with models that otherwise succesfully reproduce spectral features of the mol…
