Black Holes in Active Galactic Nuclei
M. J. Valtonen, S. Mikkola, D. Merritt +7
Supermassive black holes are common in centers of galaxies. Among the active galaxies, quasars are the most extreme, and their black hole masses range as high as to $6\cdot 10^{10}…
SW Sextantis stars: the dominant population of CVs with orbital periods between 3-4 hours
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +15
[Abridged] We present time-series optical photometry of five new CVs identified by the Hamburg Quasar Survey. The eclipses observed in HS 0129+2933, HS 0220+0603, and HS 0455+8315…
An integral monitoring of GRS1915+105: simultaneous observations with INTEGRAL, RXTE, the Ryle and Nancay radio telescopes
J. Rodriguez, G. Pooley, D. C. Hannikainen +1
Since the launch of INTEGRAL in late 2002 we have monitored the Galactic microquasar GRS 1915+105 with long exposures (~100 ks) pointings. All the observations have been conducted…
Homochirality in an early peptide world
Axel Brandenburg, Harry J. Lehto, Kirsi M. Lehto
A recently proposed model of non-autocatalytic reactions in dipeptide reactions leading to spontaneous symmetry breaking and homochirality is examined. The model is governed by act…
Recent observational progress in AM CVn binaries
G. Ramsay, C. Brocksopp, P. Groot +9
We present the results of some recent research on AM CVn systems. We present: X-ray/UV observations made using XMM-Newton; the X-ray grating spectrum of RX J1914+24; preliminary re…
Integrally monitoring GRS 1915+105 with simultaneous INTEGRAL, RXTE, Ryle and Nancay observations
J. Rodriguez, G. Pooley, D. C. Hannikainen +1
We report here the results of 2 observations performed simultaneously with INTEGRAL, RXTE, the Ryle and Nancay radio telescopes. These observations belong to the so-called and…
