Echoes of multiple outbursts of Sagittarius A* revealed by Chandra
Maïca Clavel, R. Terrier, A. Goldwurm +4
The relatively rapid spatial and temporal variability of the X-ray radiation from some molecular clouds near the Galactic center shows that this emission component is due to the re…
Fading hard X-ray emission from the Galactic Centre molecular cloud Sgr B2
R. Terrier, G. Ponti, G. Belanger +6
The centre of our Galaxy harbours a 4 million solar mass black hole that is unusually quiet: its present X-ray luminosity is more than 10 orders of magnitude less than its Eddingto…
Concurrent X-ray, near-infrared, sub-millimeter, and GeV gamma-ray observations of Sgr A*
G. Trap, A. Goldwurm, K. Dodds-Eden +13
The radiative counterpart of the supermassive black hole at the Galactic center (GC), Sgr A*, is subject to frequent flares visible simultaneously in X-rays and near-infrared (NIR)…
Multi-wavelength observations of 1RXH J173523.7-354013: revealing an unusual bursting neutron star
N. Degenaar, P. G. Jonker, M. A. P. Torres +14
On 2008 May 14, the Burst Alert Telescope aboard the Swift mission triggered on a type-I X-ray burst from the previously unclassified ROSAT object 1RXH J173523.7-354013, establishi…
Soft gamma-ray constraints on a bright flare from the Galactic Center supermassive black hole
G. Trap, A. Goldwurm, R. Terrier +11
Sagittarius A* (Sgr A*) is the supermassive black hole residing at the center of the Milky Way. It has been the main target of an extensive multiwavelength campaign we carried out…
Evidence for X-ray synchrotron emission from simultaneous mid-IR to X-ray observations of a strong Sgr A* flare
K. Dodds-Eden, D. Porquet, G. Trap +22
This paper reports measurements of Sgr A* made with NACO in L' -band (3.80 um), Ks-band (2.12 um) and H-band (1.66 um) and with VISIR in N-band (11.88 um) at the ESO VLT, as well a…
