Advective accretion disc-corona model with fallback for tidal disruption events
T. Mageshwaran, Sudip Bhattacharyya
Tidal disruption events (TDEs) show a correlation between the UV to X-ray spectral index and the Eddington ratio, with non-thermal X-ray emission at the low Eddington ratio. We con…

The GMRT High Resolution Southern Sky Survey for pulsars and transients IV: Discovery of 4 new pulsars with an FFA search
Shubham Singh, Jayanta Roy, Bhaswati Bhattacharyya +3
The fast Fourier transform (FFT) based periodicity search methods provide an efficient way to search for millisecond and binary pulsars but encounter significant sensitivity degrad…
Impact of updated Multipole Love numbers and f-Love Universal Relations in the context of Binary Neutron Stars
Bikram Keshari Pradhan, Aditya Vijaykumar, Debarati Chatterjee
Neutron star (NS) equation of state (EoS) insensitive relations or universal relations (UR) involving neutron star bulk properties play a crucial role in gravitational-wave astrono…
Modelling the energy distribution in CHIME/FRB Catalog-1

We present the results of a model-based search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO detector data from the third observing run…
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…
