Possible binary neutron star merger history of the primary of GW230529
Parthapratim Mahapatra, Debatri Chattopadhyay, Anuradha Gupta +4
Black holes (BHs) with masses between , produced by a binary neutron star (BNS) merger, can further pair up with a neutron star or BH and merge again within a Hu…

Identifying intermediate mass binary black hole mergers in AGN disks using LISA
Poulami Dutta Roy, Parthapratim Mahapatra, Anuradha Samajdar +1
We show that Laser Interferometer Space Antenna can uniquely identify the sites of intermediate-mass binary black hole (IMBBH) mergers if they occur in Active Galactic Nuclei (AGN)…
