General Coordinates Network (GCN) is a collaborative platform operated by NASA to facilitate the quick sharing of alerts and communication within the astronomy research community regarding high-energy, transient, and multi-messenger phenomena. GCN has introduced the GCN Unified Schema, the foundation for the new GCN Notices, and employs a JSON format for easy machine readability and accessibility through an open-source repository. For GCN Circulars, Neural Topic Modeling with BERTopic is used to track the evolution of different observation types over the three decades of GCN. The large-language model has been utilized to extract redshift information in tabular form and has the potential for further use in extracting useful information from the database. Focusing on one of the transients, Gamma-ray bursts (GRBs), the spectroscopic study of the prompt emission of GRBs alone is insufficient to discriminate between the models. Therefore, another constraining observable, polarization, is of great importance for unraveling the emission mechanism and is an emerging hot topic. The Cadmium Zinc Telluride Imager (CZTI) onboard AstroSat is actively measuring polarization in hard X-rays. In this talk, the novel technique of spectro-polarimetry will be presented for understanding the science of GRBs.
