Soft X-ray and FUV observations of Nova Her 2021 (V1674~Her) with AstroSat
Yash Bhargava, Gulab Chand Dewangan, G. C. Anupama +8
Nova Her 2021 or V1674 Her was one of the fastest novae to be observed so far. We report here the results from our timing and spectral studies of the source observed at multiple ep…
A Multi-wavelength Study of Swift J0503.7-2819: a Chimeric magnetic CV
Kala G. Pradeep, Kulinder Pal Singh, G. C. Dewangan +7
We present multi-wavelength temporal and spectral characteristics of a magnetic cataclysmic variable (MCV) Swift J0503.7-2819, using far ultraviolet (FUV) and X-ray data from Astro…
Swift spectra of AT2018cow: A White Dwarf Tidal Disruption Event?
N. Paul M. Kuin, Kinwah Wu, Samantha Oates +19
The bright transient AT2018cow has been unlike any other known type of transient. Its high brightness, rapid rise and decay and initially nearly featureless spectrum are unpreceden…
Superhumps linked to X-ray emission. The superoutbursts of SSS J122221.7-311525 and GW Lib
V. V. Neustroev, K. L. Page, E. Kuulkers +6
[Abridged] We present more than 4 years of Swift X-ray observations of the 2013 superoutburst, subsequent decline and quiescence of the WZ Sge-type dwarf nova SSS J122221.7-311525…
X-ray and UV observations of V751 Cyg in an optical high state
K. L. Page, J. P. Osborne, A. P. Beardmore +3
Aims: The VY Scl system (anti-dwarf nova) V751 Cyg is examined following a claim of a super-soft spectrum in the optical low state. Methods: A serendipitous XMM-Newton X-ray observ…
Swift observations of the March 2011 outburst of the cataclysmic variable NSV 1436: a probable dwarf nova (Research Note)
J. P. Osborne, K. L. Page, A. A. Henden +7
The March 2011 outburst of the poorly-studied cataclysmic variable NSV 1436 offered an opportunity to decide between dwarf nova and recurrent nova classifications. We use seven dai…
The soft X-ray spectrum of PG1211+143
K. A. Pounds, K. L. Page, J. N. Reeves
The narrow line QSO PG1211+143 has been a focus of recent attempts to understand the soft excess in AGN, while the 2001 XMM-Newton observation of this luminous AGN also provided ev…
Panchromatic study of GRB 060124: from precursor to afterglow
P. Romano, S. Campana, G. Chincarini +35
We present observations of GRB 060124, the first event for which both the prompt and the afterglow emission could be observed simultaneously and in their entirety by the three Swif…
Confirming the high velocity outflow in PG 1211+143
K. A. Pounds, K. L. Page
An XMM-Newton observation of the bright QSO PG1211+143 was previously reported to show evidence for a massive, energetic outflow, with an outflow velocity of v~0.1c based on the id…
Panchromatic study of GRB 060124: from precursor to afterglow
P. Romano, S. Campana, G. Chincarini +35
We present observations of GRB 060124, the first event for which both the prompt and the afterglow emission could be observed simultaneously and in their entirety by the three Swif…
