Accretion geometry of the black-hole binary Cygnus X-1 from X-ray polarimetry
M. Chauvin, H. -G. Florén, M. Friis +13
Black-hole binary (BHB) systems comprise a stellar-mass black hole and a closely orbiting companion star. Matter is transferred from the companion to the black hole, forming an acc…
The PoGO+ view on Crab off-pulse hard X-ray polarisation
M. Chauvin, H. -G. Florén, M. Friis +11
The linear polarisation fraction and angle of the hard X-ray emission from the Crab provide unique insight into high energy radiation mechanisms, complementing the usual imaging, t…
Shedding new light on the Crab with polarized X-rays
M. Chauvin, H. -G. Florén, M. Friis +13
Strong magnetic fields, synchrotron emission, and Compton scattering are omnipresent in compact celestial X-ray sources. Emissions in the X-ray energy band are consequently expecte…
Exploring Gamma-Ray Bursts, Their Immediate Environment and Host Galaxies
Mette Friis
Lasting anywhere from a few milliseconds to several minutes, GRBs shine hundreds of times brighter than a typical supernova, making them briefly the brightest source of cosmic gamm…
GRB 140606B / iPTF14bfu: Detection of shock-breakout emission from a cosmological gamma-ray burst?
Z. Cano, A. de Ugarte Postigo, D. Perley +13
We present optical and near-infrared photometry of GRB~140606B (), and optical photometry and spectroscopy of its associated supernova (SN). The results of our modelling i…
Thermal emission in the early X-ray afterglows of GRBs: following the prompt phase to the late times
Mette Friis, Darach Watson
Thermal radiation, peaking in soft X-rays, has now been detected in a handful of GRB afterglows and has to date been interpreted as shock break-out of the GRB's progenitor star. We…
