Discovery of periodicities in two highly variable intermediate polars towards the Galactic Center
Samaresh Mondal, Gabriele Ponti, Frank Haberl +5
We discovered Fe complex emission and pulsation in two highly variable sources (4XMM J174917.7--283329, 4XMM J174954.6--294336). The equivalent widths of 6.4 and 6.7 keV line…
Evidence for Fe K line and soft X-ray lag in NGC 7456 ULX-1
Samaresh Mondal, Agata Rozanska, Barbara De Marco +1
We report the first detection of a Fe K line and soft X-ray lag in the ultraluminous X-ray source (ULX) NGC 7456 ULX-1. The XMM-Newton spectra show the presence of the 6.4 keV…
Spectral state transitions in Circinus ULX5
Samaresh Mondal, Agata Rozanska, Patrycja Baginska +2
We performed timing and spectral analysis of multi-epoch Suzaku, XMM-Newton and NuSTAR observations of the ultraluminous X-ray source (ULX) Circinus ULX5, to put constraints on the…
An extreme Ultraluminous X-ray source X-1 in NGC 5055
Samaresh Mondal, Agata Rozanska, Eleonora Veronica Lai +1
Aims. We analyzed multi-epoch X-ray data of the Ultraluminous X-ray source (ULX) NGC 5055 X-1, with luminosity up to , in order to constrain the…
The connection between merging double compact objects and the Ultraluminous X-ray Sources
Samaresh Mondal, Krzysztof Belczyński, Grzegorz Wiktorowicz +2
We explore the different formation channels of merging double compact objects (DCOs: BH-BH/BH-NS/NS-NS) that went through a ultraluminous X-ray phase (ULX: X-ray sources with appar…
A Two Population Electron Synchrotron Model For Knots of Extended Jets
Samaresh Mondal, Nayantara Gupta
Radio observations by ALMA and upper limits on gamma ray flux by Fermi LAT have ruled out inverse Compton scattering of Cosmic Microwave Background radiation by relativistic electr…
The evolutionary roads leading to low effective spins, high black hole masses, and O1/O2 rates of LIGO/Virgo binary black holes
K. Belczynski, J. Klencki, C. E. Fields +31
All ten LIGO/Virgo binary black hole (BH-BH) coalescences reported from the O1/O2 runs have near zero effective spins. There are only three potential explanations of this fact. If…
