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 ...
Swift UVOT Grism Spectroscopy of Comets: A First Application to C/2007 N3 (Lulin)
Comets Individual Methods Data Analysis –Techniques Image Spectroscopy – Ultraviolet planetary systems
2010/11/11
We observed comet C/2007 N3 (Lulin) twice on UT 28 January 2009, using the UV grism of the Ultraviolet and Optical Telescope (UVOT) on board the Swift Gamma Ray Burst space observatory. Grism spectros...
Spectral Cross-calibration of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT Data using Gamma-Ray Bursts
gamma rays observations
2010/11/11
We report on the spectral cross-calibration results of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT instruments using simultaneously observed gamma-ray bursts (GRBs). This is the first attempt to...
Photometric redshifts for GRB afterglows from GROND and Swift/UVOT
gamma rays bursts Techniques photometric
2010/11/11
Aims. We present a framework to obtain photometric redshifts (photo-zs) for gamma-ray burst afterglows. Using multi-band photometry from GROND and Swift/UVOT, photo-zs are derived for five GRBs for wh...
Swift: the science across the rainbow. Mission Overview and Highlights of Results
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
I present an overview of the Swift mission, which was launched on November 20, 2004 to discover and observe the most energetic of astrophysical phenomena, gamma-ray bursts (GRBs).
