The Deep Newtonian Regime in Late-Time Blast Waves: Inevitable Transition and Distinct Flux Signatures
Sk. Minhajur Rahaman, Jonathan Granot, Paz Beniamini
In many astrophysical transients, outflows drive shocks into the ambient medium, accelerating electrons to non-thermal energy distributions that produce broadband synchrotron emiss…
Persistent radio sources associated with fast radio bursts: Implications from magnetar progenitors
Sk. Minhajur Rahaman, Sandeep Kumar Acharya, Paz Beniamini +1
The rare association of three persistent radio sources (confirmed PRS1 and PRS2, candidate PRS3) with repeating fast radio bursts (FRB 20121102A, 20190520B, 20201124A) offers a uni…
Internal Shocks Hydrodynamics: the Collision of Two Cold Shells in Detail
Sk. Minhajur Rahaman, Jonathan Granot, Paz Beniamini
Emission in many astrophysical transients originates from a shocked fluid. A central engine typically produces an outflow with varying speeds, leading to internal collisions within…
Prompt Gamma-Ray Burst Emission from Internal Shocks -- New Insights
Sk. Minhajur Rahaman, Jonathan Granot, Paz Beniamini
Internal shocks are a leading candidate for the dissipation mechanism that powers the prompt -ray emission in gamma-ray bursts (GRBs). In this scenario a compact central source…
Pulsar radio emission mechanism II. On the origin of relativistic Langmuir solitons in pulsar plasma
Sk. Minhajur Rahaman, Dipanjan Mitra, George I. Melikidze +1
Observations suggest that coherent radio emission from pulsars is excited in a dense pulsar plasma by curvature radiation from charge bunches. Numerous studies propose that these c…
Externally-driven plasma models as candidates for pulsar radio emission
Sk. Minhajur Rahaman, Dipanjan Mitra, George I. Melikidze
Coherent radio emission from pulsars originates from excited plasma waves in an ultra-relativistic and strongly magnetized electron-positron pair plasma streaming along the open ma…
Mode changing, subpulse drifting and nulling in four component conal pulsar PSR J2321+6024
Sk. Minhajur Rahaman, Rahul Basu, Dipanjan Mitra +1
In this study, we report on a detailed single pulse polarimetric analysis of the radio emission from the pulsar J2321+6024 (B2319+60) observed with the Giant Metrewave Radio Telesc…
Pulsar radio emission mechanism I : On the amplification of Langmuir waves in the linear regime
Sk. Minhajur Rahaman, Dipanjan Mitra, George I. Melikidze
Observations suggest that in normal period radio pulsars, coherent curvature radiation is excited within 10 of the light cylinder. The coherence is attributed to Langmuir mode…
