Bright X-ray Pulsars: how outflows influence beaming, pulsations and pulse phase lags
Alexander A. Mushtukov, Simon Portegies Zwart
Extreme accretion in X-ray pulsars (XRPs) results in radiation-driven outflows launched from the inner parts of the accretion disc. The outflows affect the apparent luminosity of t…
Statistical features of multiple Compton scattering in a strong magnetic field
Alexander A. Mushtukov, Ivan D. Markozov, Valery F. Suleimanov +4
Compton scattering is a key process shaping spectra formation and accretion flow dynamics in accreting strongly magnetized neutron stars. A strong magnetic field affects the scatte…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
The Signature of a Windy Radio Supernova Progenitor in a Binary System
Almog Yalinewich, Simon Portegies Zwart
Type II supernova progenitors are expected to emit copious amounts of mass in a dense stellar wind prior to the explosion. When the progenitor is a member of a binary, the orbital…
The contribution of young core-collapse supernova remnants to the X-ray emission near quiescent supermassive black holes
Alex Rimoldi, Elena Maria Rossi, Elisa Costantini +1
Appreciable star formation, and, therefore, numerous massive stars, are frequently found near supermassive black holes (SMBHs). As a result, core-collapse supernovae in these regio…
Simulations of the tidal interaction and mass transfer of a star in an eccentric orbit around an intermediate-mass black hole: the case of HLX-1
Edwin van der Helm, Simon Portegies Zwart, Onno Pols
The X-ray source HLX-1 near the spiral galaxy ESO 243-49 is currently the best intermediate-mass black hole candidate. It has a peak bolometric luminosity of erg s…
