Effort towards combined MAGIC & LST-1 data analysis along with an open and reproducible multi-instrument gamma-ray analysis

Very high energy gamma rays from space are created in the most violent processes in the universe and are unique and powerful probes for astrophysics and for fundamental physics in extreme conditions. During the last decade, the ground-based gamma-ray experiments around the globe have given an enormous boost to this eld through exciting discoveries of several astrophysical gamma-ray emitters.
 

MAGIC is one of the state-of-the-art ground-based gamma-ray experiments located on the Canary Island of La Palma, Spain. The rst Large Size telescope (LST-1) of the Cherenkov Telescope Array (CTA) is also installed at La Palma and is about 100 m away from MAGIC telescopes and is in its commissioning phase. The co-location of LST1 and MAGIC offers the great opportunity of cross-calibrating the two systems on an event-by-event basis. In this talk, I shall discuss our efforts for joint analysis for MAGIC & LST-1 data. In addition to this, I will also discuss the result of an attempt towards multi-instrument & reproducible data analysis with open-source software, which requires a common data format. I shall also talk about the MAGIC experiments. On-site data analysis pipeline along with its recently developed high-level analysis chain, and the validation of CTA Science tools through analysis of simulated data.
