A remarkable long-term light curve, and deep, low-state spectroscopy: Swift & XMM-Newton monitoring of the NLS1 galaxy Mkn 335
remarkable long-term light curve low-state spectroscopy Swift XMM-Newton monitoring the NLS1 galaxy
2012/2/23
The Narrow-line Seyfert 1 galaxy (NLS1) Mkn 335 is remarkable because it has repeatedly shown deep, long X-ray low-states which show pronounced spectral structure. It has become one of the prototype A...
Swift monitoring of the central X-ray source in RCW 103
pulsars: general – stars: neutron – X-rays: individual: 1E 161348–5055
2011/10/11
The X-ray source 1E 161348-5055 lies at the centre of the 2-kyr-old supernova remnant RCW 103. Owing to its 24-ks modulation, orders-of-magnitude flux variability over a few months/years, and lack of ...
X-ray monitoring of classical novae in the central region of M 31. II. Autumn and winter 2007/2008 and 2008/2009
High Energy Astrophysical Phenomena (astro-ph.HE) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M 31. We performed a dedicated monitoring of the M 31 central region ...
