Swift Discovery of a New Soft Gamma Repeater, SGR J1745-29, near Sagittarius A*
- J. Kennea, D. Burrows, +10 authors N. Gehrels
- Physics
- 9 May 2013
Starting in 2013 February, Swift has been performing short daily monitoring observations of the G2 gas cloud near Sgr A* with the X-Ray Telescope to determine whether the cloud interaction leads to… Expand
DISCOVERY, PROGENITOR AND EARLY EVOLUTION OF A STRIPPED ENVELOPE SUPERNOVA iPTF13bvn
- Y. Cao, M. Kasliwal, +24 authors C. Gelino
- Physics
- 4 July 2013
The intermediate Palomar Transient Factory reports our discovery of a young supernova, iPTF13bvn, in the nearby galaxy, NGC 5806 (22.5 Mpc). Our spectral sequence in the optical and infrared suggests… Expand
A CHANDRA/HETGS CENSUS OF X-RAY VARIABILITY FROM Sgr A* DURING 2012
- J. Neilsen, M. Nowak, +13 authors F. Baganoff
- Physics
- 22 July 2013
We present the first systematic analysis of the X-ray variability of Sgr A ∗ during the Chandra X-ray Observatory’s 2012 Sgr A ∗ X-ray Visionary Project. With 38 High Energy Transmission Grating… Expand
A four-year XMM-Newton/Chandra monitoring campaign of the Galactic centre: analysing the X-ray transients
- N. Degenaar, R. Wijnands, +5 authors M. V. D. Klis
- Physics
- 26 April 2012
We report on the results of a four-year long X-ray monitoring campaign of the central 1.2 square degrees of our Galaxy, performed with Chandra and XMM-Newton between 2005 and 2008. Our study focuses… Expand
A powerful flare from Sgr A* confirms the synchrotron nature of the X-ray emission
- G. Ponti, E. George, +21 authors I. Waisberg
- Physics
- 9 March 2017
We present the first fully simultaneous fits to the near-infrared (NIR) and X-ray spectral slope (and its evolution) during a very bright flare from Sgr A*, the supermassive black hole at the Milky… Expand
The X-ray flaring properties of Sgr A* during six years of monitoring with Swift
- N. Degenaar, J. Miller, J. Kennea, N. Reynolds, R. Wijnands
- Physics
- 26 October 2012
Starting in 2006, Swift has been targeting a region of sime 21' × 21' around Sagittarius A* (Sgr A*) with the onboard X-Ray Telescope. The short, quasi-daily observations offer a unique view of the… Expand
Discovery of 10 mHz quasi-periodic oscillations likely from IGR J17091-3624

X-RAY EMISSION AND ABSORPTION FEATURES DURING AN ENERGETIC THERMONUCLEAR X-RAY BURST FROM IGR J17062−6143
- N. Degenaar, J. Miller, R. Wijnands, D. Altamirano, A. Fabian
- Physics
- 19 December 2012
Type-I X-ray bursts are thermonuclear explosions occurring in the surface layers of accreting neutron stars. These events are powerful probes of the physics of neutron stars and their surrounding… Expand
An X-ray-UV correlation in Cen X-4 during quiescence
- E. Cackett, E. Brown, N. Degenaar, J. Miller, M. Reynolds, R. Wijnands
- Physics
- 16 October 2012
Quiescent emission from the neutron star low-mass X-ray binary Cen X-4 is seen to be variable on time-scales from hundreds of seconds to years, suggesting that at least in this object, low-level… Expand
THE PECULIAR GALACTIC CENTER NEUTRON STAR X-RAY BINARY XMM J174457-2850.3
- N. Degenaar, R. Wijnands, +6 authors G. Ponti
- Physics
- 17 June 2014
The recent discovery of a millisecond radio pulsar experiencing an accretion outburst similar to those seen in low mass X-ray binaries, has opened up a new opportunity to investigate the evolutionary… Expand
