| Abstract: | Markarian 501, a high frequency peaked blazar at a redshift of z = 0.0337,
is well known for its frequent flaring episodes across multiple
wavelengths, from radio to very high energy (VHE) gamma-rays. MACE
telescope detected a VHE gamma-ray emission with ~90% increase compared to
the preflare state on 27 June 2022. Quasi-simultaneously, an X-rays
flaring episode from Markarian 501 was detected by Swift-XRT in the same
month with the peak X-ray flux increasing up to ~80%
above its average preflare level. In this work, we present a comprehensive
multiwavelength analysis of Marakarian 501 using the data from the MACE
observations, high energy (HE) data from Fermi LAT and X-ray data from
Swift XRT and UVOT. The X-ray variability and its correlation with the
HE/VHE gamma-ray emission will be investigated. |
