Characterizing the Scale Height and Filamentary Structure of Radiatively Cooled MADs
Akshay Singh, Damien Begue, Asaf Pe'er
Radiative cooling can strongly influence the structure and dynamics of black hole accretion disks. Here, we perform general relativistic magnetohydrodynamic (GR-MHD) simulations of…
An unusual type-I X-ray burst from the neutron star X-ray binary IGR J17591-2342: a double-photospheric-radius-expansion burst?
Sudip Bhattacharyya, Akshay Singh, Andrea Sanna
Type-I X-ray bursts observed from neutron stars originate from intermittent unstable thermonuclear burning of accreted matter on these stars. Such bursts, particularly those reachi…
AstroSat timing and spectral analysis of the accretion-powered millisecond X-ray pulsar IGR J17591--2342
Akshay Singh, Andrea Sanna, Sudip Bhattacharyya +5
IGR J17591--2342, a transient accretion-powered millisecond X-ray pulsar, was discovered during its 2018 outburst. Here, we present a timing and spectral analysis of the source usi…
Radiative cooling changes the dynamics of magnetically arrested disks
Akshay Singh, Damien Bégué, Asaf Pe'er
We studied magnetically arrested disks (MAD) around rotating black holes (BH), under the influence of radiative cooling. We introduce a critical value of the mass accretion rate $\…
