Description
The Major Atmospheric Cherenkov Experiment (MACE) has been conducting
regular observations of very high-energy (VHE) gamma-ray sources since
2021. MACE has successfully detected gamma-ray emission from the standard
candle Crab Nebula, with its measured differential energy spectrum in
agreement with earlier results from similar telescopes. In addition to the
Crab Nebula, MACE has also detected VHE gamma-ray emission from several
sources, including Mrk 501, Mrk 421, and 1ES 1959+650. It was also
deployed for VHE emission searches from a sample of six high-redshift
blazars (0.3 < z < 0.998), for which upper limits on the integral flux
were estimated. MACE detected two episodic VHE gamma-ray activity from the
radio galaxy NGC 1275 in December 2022 and January 2023 and another
enhanced gamma-ray activity on January 25, 2025. Furthermore, on January
26, 2025, MACE detected VHE gamma-ray flare from the flat-spectrum radio
quasar (FSRQ) OP 313.
In this contribution, we will present key scientific results from MACE
over the past four years.
