The pulsating hot subdwarf Balloon 090100001: results of the 2005 multisite campaign
A. Baran, R. Oreiro, A. Pigulski +28
We present the results of a multisite photometric campaign on the pulsating sdB star Balloon 090100001. The star is one of the two known hybrid hot subdwarfs with both long- and sh…
A massive binary black-hole system in OJ287 and a test of general relativity
M. J. Valtonen, H. J. Lehto, K. Nilsson +23
Tests of Einstein's general theory of relativity have mostly been carried out in weak gravitational fields where the space-time curvature effects are first-order deviations from Ne…
The new sample of giant radio sources II. Update of optical counterparts, further spectroscopy of identified faint host galaxies, high-frequency radio maps, and polarisation properties of the sources
J. Machalski, M. Jamrozy, S. Zola +1
Our sample of giant radio-source candidates, published in Paper I (Machalski et al. 2001), is updated and supplemented with further radio and optical data. In this paper we present…
Multicolour photometry of Balloon 090100001: linking the two classes of pulsating hot subdwarfs
A. Baran, A. Pigulski, D. Koziel +3
We present results of the multicolour UBVR photometry of the high-amplitude EC14026-type star, Balloon 090100001. The data span over a month and consist of more than a hundred hour…
Search for Southern-Hemisphere Giant Radio Galaxies with SALT
J. Machalski, S Zola, D. Koziel +1
An extensive search for distant Giant radio galaxies on the southern hemisphere is justified. We emphasize the crucial role of optical spectroscopy in determination of their basic…
