Polarisation angle variability in tidal disruption events
A. Floris, I. Liodakis, K. I. I. Koljonen +9
Tidal disruption events (TDEs) occur when a star is disrupted by the tidal forces of a supermassive black hole, and these events produce bright multi-wavelength flares. Polarimetri…
Repeating flares, X-ray outbursts and delayed infrared emission: A comprehensive compilation of optical tidal disruption events
D. A. Langis, I. Liodakis, K. I. I. Koljonen +10
TDEs have been proposed as valuable laboratories for studying dormant black holes. However, progress in this field has been hampered by the limited number of observed events. In th…
Polarimetric Diversity in Tidal Disruption Events: Comparative Study of Low-Polarised sources with AT2020mot
A. Floris, I. Liodakis, K. I. I. Koljonen +13
Tidal disruption events (TDEs) occur when a star is disrupted by the tidal forces of a supermassive black hole (SMBH), producing bright multi-wavelength flares. Among these events,…
The peculiar hard state behaviour of the black hole X-ray binary Swift J1727.81613
A. K. Hughes, F. Carotenuto, T. D. Russell +37
Tracking the correlation between radio and X-ray luminosities during black hole X-ray binary outbursts is a key diagnostic of the coupling between accretion inflows (traced by X-ra…
Birthplaces of X-ray emission lines in Cygnus X-3
Osmi Vilhu, Karri I. I. Koljonen
We investigate the formation of X-ray emission lines in the wind of the Wolf-Rayet (WR) companion in Cyg X-3 by analyzing their orbital dynamics using Chandra High Energy Transmiss…
Jet break revealed in the transitional millisecond pulsar candidate 4FGL J0427.8-6704
K. I. I. Koljonen, M. Linares, J. C. A. Miller-Jones
Understanding the formation and properties of relativistic jets from accreting compact objects has far-reaching implications in astrophysics. Transitional millisecond pulsars (tMSP…
