Hierarchical mergers

Webmergers encounter new black holes, resulting in so-called hierarchical mergers. Hierarchical events carry signatures such as higher-than-usual black hole mass and spin. Here we show that the recently reported gravitational-wave candidate, GW170817A, could be the result of such a hierarchical merger. In particular, its chirp mass ∼40Me and WebEducation : IIM Calcutta (PGDBA) , IIT DELHI (B.TECH) , Work Experience: 4+ years of work experience in the implementation of advance algorithms in • Neural Networks (BERT, Generative Adversarial Networks, Hierarchical Attention, Encoder-Decoder Models, LSTM, CNN), • NLP (Topic Modeling, Entity Linking (spaCy), WSD, Sentiment …
