IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
Colour variations in the GRB 120327A afterglow
A. Melandri, S. Covino, E. Zaninoni +42
We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate the possible causes of the observed early time colour variatio…
Stochastic modeling of multiwavelength variability of the classical BL Lac object OJ 287 on timescales ranging from decades to hours
A. Goyal, L. Stawarz, S. Zola +109
We present the results of our power spectral density analysis for the BL Lac object OJ\,287, utilizing the {\it Fermi}-LAT survey at high-energy -rays, {\it Swift}-XRT in X-rays…
The remarkable outburst of the highly evolved post-period-minimum dwarf nova SSS J122221.7-311525
V. V. Neustroev, T. R. Marsh, S. V. Zharikov +22
We report extensive 3-yr multiwavelength observations of the WZ Sge-type dwarf nova SSS J122221.7-311525 during its unusual double superoutburst, the following decline and in quies…
Effective Temperatures of Cataclysmic Variable White Dwarfs as a Probe of their Evolution
A. F. Pala, B. T. Gänsicke, D. Townsley +29
We present HST spectroscopy for 45 cataclysmic variables (CVs), observed with HST/COS and HST/STIS. For 36 CVs, the white dwarf is recognisable through its broad Ly absorption p…
