Since the first detection of the gravitational wave from a binary black hole, the LIGO-Virgo-KAGRA (LVK) collaboration has detected in total 90 events from compact binary coalescences, establishing the field of gravitational wave astronomy. In addition to shedding light on the properties of compact objects e.g. black holes and neutron stars, the joint observation of such objects together with electromagnetic emission will bring us further enriched insight on nuclear physics and cosmology. Early 2023, the forth observing run is going to take place and various methods have been extensively developed towards it. Today, I will talk about methods to detect gravitational waves in low latency, which plays a crucial role in so-called multi-messenger astronomy. In particular, this talk will be focused on the methodology of a low-latency detection pipeline, GstLAL. GstLAL can also incorporate the detection method with negative latency, i.e. early warning. I will briefly describe its prospect in the upcoming forth observing run by the LVK collaboration.
